Which will work better on t-mobile: Samsung Galaxy S3 GT-i9300 or GT-i9305?

While this is sort of a "shopping" question, it is also a question about if these phones will work on t-mobile's network.

T-Mobile does not (currently) have LTE. So if the device has LTE, you will not use the LTE chip.

Will the devices work on T-Mobile? Yes. Will you get the T-Mobile 4G speeds? Well that depends on what bands (or frequencies) the device supports.

T-Mobile has support for the following bands for their 4G netowork:

1700 MHz | UMTS/HSPA/HSPA+
1900 MHz | UMTS/HSPA/HSPA+
1700 MHz | LTE (this is the band they will use when they roll out LTE)

According to the Spec Sheet on Amazon of the i9300:

3G Network | HSDPA 850 / 900 / 1900 / 2100

AFAIK, internationally, HSPA+ is not considered 4G, so based on this, yes this phone will give you T-Mobile 4G

The i9305 on the other had, according to Amazon, does not appear to have the bands available for T-Mobile:

4G Network: LTE 800 / 1800 / 2600
3G: HSDPA 850 / 900 / 2100

Now, what I am actually making here is just an assumption, because it supports the bands that T-Mobile supports. I cannot say with 100% certainty that it will operate with their 4G speeds.


Google Photos did not compress a few items, even on high quality mode

It's best to forget about it since the storage for the uncompressed items isn't coming out of the 15 GB Google Drive limit anyway; although the unlikely wish of downloading the items would mean downloading uncompressed items - a very small price to pay for a free service.


The Android built in screenshot function does not support to specify the filename.

One alternative way for triggering a screenshot would be to use adb shell via USB or Wifi from a connected PC. On the shell you can execute screencap /sdcard/screenshot1.png and therefore specify the filename.


How can I find the group id (gid) for the sdcard_r group on android?

Use the following command to see GID of the concerned group:

id -G group_name

Courtesy of this answer of doylefermi.

It is very much possible that the GID would be 1028 given this line in source code of Android.


It should be located under Android Settings > Location & Security.

But you need apps that support this feature in order to make full use of it. If you have a Google Apps or an exchange account your admin will be able to use the corresponding features like password reset etc.

Certain apps (examples: Llama / WidgetLocker / WaveSecure) when made as device administrators are then allowed a higher level of access to system features.


A problem with finding apps in the market on the Phone

Some apps have certain hardware requirements that your phone might not support (e.g. screen resolution.) The Market has the ability to filter out such apps from search results.


How can I factory-restore a Samsung J5 (2015) SM-500FN?

A friendly forum user pointed me to this updated version of TWRP which I could install using the already installed TWRP.

After upgrading the TWRP itself, I was then able to install the ROM I wanted. Problem solved!


I'm not sure what you're wanting to back up, but most backup applications on the Play Store will do this for you.  Examples are MyBackup Root, Titanium Backup, and Helium.

EDIT:  Scratch that.  As mentioned by Izzy in the comments below, you must be rooted for these apps to work, as there is a..."feature"...in Android 4.4 KitKat that prevents "rouge" SD Card access: link


It is recommended to wipe dalvik/cache, factory reset before and after flashing anything in recovery.

Google Messenger: Incorrect profile letter

It happens when you save your own phone number with someone's else name by mistake. If it's the case, you just need to double tap on the wrong "letter" (which is "S" in your case) that is showing next to your text messages and you'll be able to change the name associated with the texts.


Galaxy S3 , Supersu reports no SU binary installed

I would suggest you root again eg. with CF-Autoroot. You can find some answers in the FAQ of xda-developers: http://forum.xda-developers.com/showthread.php?t=2148708

If you have CWM-recovery already installed then just boot into it and reboot again. It should tell you that root access is missing and you should fix that by simply accepting the recovery's offer of fixing root for you. Then you just need to update SuperSU and use it to update the su binary.

Even though they advise you to use Odin on Windows using Heimdall should work as well.


Is it possible to add an audio bluetooth profile to my phone?

See my answer to a similar question - the problem is that within the Bluetooth AD2P profile (for stereo quality audio) Android phones aren't designed to be a "sink" (a receiver of media) only a source. You're right in that this is a limitation of the Bluetooth stack on your phone, but so far the info I've found says that trying to alter the stack comes with moderate amounts of pain and compromise. Perhaps you're more adventurous than I?


Reinstall Gallery app on Samsung Galaxy S3

Personally I would use the Google Photos app, but yes, you can re-download it.

Here is a list of downloads for the S3 stock apps for Jellybean:

http://www.the-area51.com/2013/01/samsung-galaxy-s3-jellybean-stock-apks.html

Download the gallery apk file on your phone, and open it. A promt will open, click install. Once it's finished, you can delete the file you downloaded, and open the app like you normally would.


How to diagnose battery drain on Android device using logcat?

Are you sure, it's not any app that is draining your battery? You can find this out by booting you phone into Safe mode. Read How to boot your phone into safe mode for instructions. If your battery doesn't drain in Safe mode, try uninstalling the apps that you installed after you started seeing this weird behavior. If you are not able to figure out which app it is, try factory resetting it. Also, if the battery is draining so quickly it might very well be a faulty battery.


bind mount / symlink - keep destination "tree" on removal of source?

That sounds really crazy...

At first glance, I have a guess that while you can unmount the source directory of a bind mount, you must keep the underlying device attached for a bind mount to work.

I confirmed my guess in experiments on my OnePlus 6 (Android Linux 4.9.65) and my Ubuntu 18.04 (real Linux 4.15.0) and the result is same.

On Ubuntu, I inserted a USB flash drive (ext4 filesystem) and mounted it to /mnt/usb, and I bind mounted /mnt/usb/data to /mnt/bind

I unmounted /mnt/usb while keeping the flash drive attached, and I can access /mnt/bind with no error. All changes to /mnt/bind reflected to <drive root>/data (verified later).
Then I detached the flash drive and attempted to access /mnt/bind, and got this message:

ls: reading directory '/mnt/bind': Input/output error

On my OnePlus 6, I inserted a USB flash drive via OTG (exFAT filesystem). I mounted the device /dev/block/vold/public:8:97 to /data/dev, and bind-mounted /data/dev/Android to /data/bind.

I unmounted /data/dev while keeping the OTG attached, and all the data remains in /data/bind and is accessible without errors.
Then I turned off "OTG function" in the Settings app, the Android mount point /mnt/media_rw/xxxx-xxxx disappeared, but I can still access my bind mount.
Next I detached the OTG drive and attempted to access /data/bind and got this:

ls: reading directory `/data/bind`: I/O error

A side note is, unlike Ubuntu, access to /data/bind remained available for around half a minute, but directories that I didn't previously visited weren't accessible anymore, only the directories that I visited before detaching the drive was still accessible.

That's it. The conclusion is in the top paragraph.


Why is internet switched off when switching 2G/3G?

The radio frequency of a 2G radio operates in the range of 900 and 1800 MHz (source)-  varying from country to country.  The radio frequency of a 3G radio operates in the range of 2100 Mhz (source).

As far as Samsung Galaxy Nexus LTE L700's specification is concerned, the 2G frequency is CDMA 800 / 1900, 3G frequency is CDMA2000 1xEV-DO and LTE (4G) frequency is LTE 1900.

As far as Samsung Galaxy Nexus I9250's specification is concerned, the 2G frequency is GSM 850/900/1800/1900, 3G frequency is HSDPA 900/1700/1900/2100 and LTE (4G) frequency is LTE 2300/2400.

The above examples clearly means that the phones use different radio frequency for each type of network and hence when switching from one to another it goes into no network mode momentarily and hence the data connection stops.

Altering left-right sound balance on Android 6.0.1

There's an older related post on this topic: How do I adjust audio balance of my Android phone headphones out? – but it seems that it's not matching recent versions of Android anymore. Like this CNET post it recommends going to Settings › Accessibility and check the "Hearing" section (which I could not found on my Lollipop devices – according to the linked question, it might be device-specific and not available on all devices – the Samsung S6 e.g. seems to have this, for other devices it seems to have been removed) for either the "Sound balance" or the "Music Effects" item. So if your device has that: great, you're done!

If your device does not have this setting, there are 3rd party solutions. But as far as I am aware, they all require your device being rooted. If that condition is met, you can e.g. use:

the Audio Balance XPosed module (see this XDA thread for details)
the Viper music effects app recommended in the linked question (still maintained; the download page mentions "Android 4.0~6.0")

As much as I've looked around, these seem to be the only options available currently.

Update by Victor Spinei after evaluation:

In order to download and install this you might need to check:

Settings/Security/Unknown source to be ON
Settings/Google/Scan device for security threats to be OFF
Close security applications like Lookout
Do not forget to restart all those services after installing the audio apps.


I was able to install the app "Find My Device" to the phone. I then used the app to "secure my device". This caused my account to be signed out from the device. I had to sign back in. My device now appears in the Find My Device webpage.

This didn't fix any of the "phone number not available" settings, so I guess they're not relevant.

How do I get to the "Home" in Play Store?

Whenever you navigate the Play Store using the app, each app page has a left-arrow just below the status/notification bar. I have just tested this to 20 levels deep, and the arrow brings you to one of 2 places:

Play Store home directly, or,
that account's navigation menu, including Store Home as the first option.


Is a rooted phone safe for phone banking?

Stock roms are really unsafe with root because they are not made and optimized to be used with root access. Therefore it's always recommended to flash a secure custom rom. You can try lineage OS.. regarded as very secure.
I believe that custom open source Android ROMs like Lineage OS are secure just because of the fact that their full source code is open source.
And the professionals and hobbyists out there definitely would check and ensure that it has no secret bugs.
The developers would also not like to damage their reputations by open sourcing a software with spywares that everyone including the topmost brains in the world can scrutinize.


How to read data pertaining to running applications?

Cases 1+3 show the app is currently running; basically, both are "task manager" views.

Number 2 is rather related to "preferred apps" for a given action: if you e.g. have two web browsers installed, this decides which one is launched if you tap an URL.

Number 4 is the "application manager". Usually, an "active force-stop button" should indicate a running app which you can "kill" by clicking this; but I'm not 100% sure whether the button is always disabled when the app in question does not run.

How can I configure my phone to automatically connect to remembered wifi networks? (after having left the device to sleep)

I have this same problem, intermittently, with my N1/froyo/CM6. I don't know why it happens, but it's been happening since the froyo update afair.

I've noticed it happens less often if I stay in one place. This led me to the theory that, since I live at a university, the fact that networks will pop in and out of range even as I enter my dorm and walk up to my room will make my N1 think that the network's unstable and thus disable it.

Toggling definitely fixes the issue.


unable to connect i9100 in cwm recovery mode

You could give adb a try, and use adb push </source/on/PC/file.zip> <target/on/Nexus/file.zip> to transfer the files.

I you don't have ADB installed on your machine yet, and don't want to install the full SDK, take a look at Is there a minimal installation of ADB? Also, for more information on ADB, there's always our adb tag-wiki as a good starting point.


Connect a USB soundcard to an Android phone? And use it for videos?

Yes it is possible.
I'm doing this with several devices for amateur radio and video production with KineMaster Pro.
For amateur radio, I use the DigiMaster MiniProSC connected via OTG cable to a Nexus 9 via OTG cable. I also do this with SignaLink usb connected the same way. Both of these devices have internal usb sound cards with audio in, audio out, and usb connection between android tablet and the radio.

For YouTube videos, I use KineMaster Pro with Zoom H2 and H4 as external microphone or line in. Both connected via USB to the Nexus 9, and both work perfectly!

I know this is an old thread, but when I saw the answer from the guy who says it doesn't work, I wanted to correct this out-of-date information, letting everyone who makes there way here via Google search of the correct answer!

Btw, it also works on Samsung galaxy s4 i9506. I've tested on Android 5, 6 and 7 successfully.

Thanks


Bricked my Asus TF300T? Manual JB update

Solved. ASUS released the new firmware in its website.

Flashing it unbricked my device:

Download the stock firmware from ASUS’s official website. On the website, select Android in the OS drop down menu, then select Firmware, and download the latest firmware.
Extract the downloaded firmware file. You will get another archive file. Extract this one as well to get several files. One of these files will be named “blob”, which is the one we need to use.
Install Android SDK for Windows.
Shut down the tablet. Hold Power + Vol Down buttons until a message appears saying “Press Vol. Up to enter RCK (5s)”. However, DO NOT press the Volume Up button. Instead, wait for 5 seconds till a new menu appears. Then, in less than 10 seconds, press Volume Down once to highlight the USB icon, then press the Volume Up button to validate.
Open Command Prompt on your computer from Start » All Programs » Accessories (or open Start menu, type cmd and press the Enter button).
Now, type the following commands in command prompt to flash the stock ROM, pressing Enter after each command:

> cd C:...\Path-to-Andoid-SDK\platform-tools\

> fastboot devices

> fastboot -i 0x0B05 flash system C:...\Path-to-blob\blob

> fastboot -i 0x0B05 reboot

After some troubled tries I could save (not sync) all my contacts.
First try was to remove all contacts again and sync with Mac address book (which is also synced with Google) using Kies (Samsung); it always crashed when around 80% sync task was performed. Then I remove all contacts again, created a vcf file containing all Address Book data, copied it to the phone and finally imported data from file.

Just to check sync with Google I added a test contact to Address Book, synced to google and then synced from the phone. The contact was added despite 'Sync is currently experiencing problems...' was displayed again.

Galaxy S5 / Lollipop: video player not showing video, only audio

Solved. It was actually this app: https://play.google.com/store/apps/details?id=com.teamviewer.quicksupport.addon.samsung

After deinstalling this app and restarting my phone the Android video player app works again. Just deinstalling Teamviewer Quicksupport itself neither deleted this add-on nor helped with my problem.

EDIT: Also, deinstalling this app removed very strange lags and pauses at certain display animations (fade effects, e.g. of the lock screen camera button and in apps) that I experienced while I had this app installed.


I'm looking to buy a smartwatch. How can I tell if an app in the Play Store is compatible with it before buying the device?

The easiest way to check is to make sure it is labeled either "Wear OS", "Wear OS by Google" or "Android Wear".

Another way to check is if the watch supports the Google Assistant, it most likely is running Wear OS and should be supported as well.

Finally, if you want to be absolutely positive, you can always check the Wear OS website


Here is the XML of a Tasker Profile and Tasks that cycle WiFi on the cycle you describe above, as well as screen shots.

How can I get the APK file of an app after installing it from Google Play?

Multiple ways, but the easiest one, I suppose, is to install a backup type app such as App Backup Restore. Take the backup of the the target app and its APK would be saved inside a directory under the default storage (/sdcard).

  Once I find the APK file of an app, can I copy it out of my android phone to my Ubuntu laptop and then extract the hidden document file in the apk file? Or do I have to extract on my android phone?

An APK is an archive (MIME type: application/zip). You can copy it to your laptop alike any multimedia file.

As for the extraction of the contents, there are multiple apps on Play Store which supports extracting a ZIP file, so it is up to you to extract the app on Android or in your PC to explore its contents.


Settings -> Wireless and network -> Wi-Fi settings -> (Menu) Advanced -> Wi-Fi sleep policy -> Never.

How can I tell if my Samsung S7 supports connecting to a wired ethernet via a usb OTG cable?

Like any other computer system Android also requires a driver for talking to a device.

However unlike regular PCs you can't just install a driver, instead you only have the drivers the manufacturer included when building the Android system.

In a terminal or on an adb shell you can list all the drivers that were included in your kernel:

ls /system/lib/modules

If the list contains for example the driver usbnet there is a chance that an USB Ethernet adapter may work.


I was not able to mount ext4 with stickmount alone, but I had some success using USB OTG Helper with stickmount still installed.

External keyboard for Galaxy tablet 2 7.0

A female-to-female USB adaptor can't fill the role of a USB-on-the-go cable. A device that uses USB-OTG has the USB hardware and the drivers needed to act as a USB host or a USB peripheral. The wiring of the USB-OTG cable tells the device which role to act in. (The host side has two pins wired together, but the peripheral side doesn't.)

Most USB peripherals don't have the required hardware or software to act as a USB host. The Samsung Galaxy Tablet 2 7.0 does, but it needs a correctly wired adaptor so that it knows it's supposed to be acting as a host.

Samsung makes and sells a 30-pin to USB host adaptor, so you might be able to find one at your local electronics shop.

iPhone/Android Nearby Filesharing Systems Across Platforms

Currently, it is not possible as AirDrop uses Bluetooth to create a peer-to-peer Wi-Fi network between the devices.
But here are some ways Android and iPhone/iOS users can share files with each other:

1.Use email
2. Use an app to share locally Like Zapya or Shareit
3. Use an app to share semi-locally
4. Use an online file-transfer service

Or you can jailbreak you i-device then use your Bluetooth connection to share data between i-devices and  others.


I assume your recovery partition was wiped out partially during factory reset and I see the only solution here - to make full reinstall via Odin using one of the stock images.
Then you can flash TWRP again and re-root.


Phone borked after clearing dalvik cache

Never mind. I managed to uninstall some apps to free up some space and then after rebooting, I was able to use Link2SD to move the Dalvik Cache, which gave me about 230MB free instead of 12MB!

I still had some problems so cleared the Dalvik cache again but that put it back on the Internal Storage and used up all the free space again, so I had to uninstall a few more apps and move it again but at least it's usable now. I'm getting a new phone this week anyway, so I won't waste much time getting it perfect, as I'll just wipe it and reinstall a clean ROM before giving it to a friend.


How to stop Foursquare from turning on Wi-Fi?

You could try removing the permission to change the Wi-Fi state with something like LBE Privacy Guard. There's also the possibility of using the method described in a similar question on here, this involves changing the .apk file and no root is needed.

There's a few caveats though:

Biggest one is that when Foursquare tries to use the removed the permission it may well break depending on how the developers coded it.
LBE Guard needs root, so you'll need to have a rooted phone.
There have been suggestions here and here LBE Guard isn't all it's cracked up to be (buggy, hard to uninstall, might mine your data?) despite the high ratings in the marketplace.

How can I install ClockworkMod recovery on my Motorola Defy+?

Luckily rooting the Motorola Defy is pretty simple and doesn't require any extraneous measures. Please see this link for a tutorial on how to root and install a custom recovery (ie. clockworkmod) on your Motorola Defy.

As far as installing an ICS ROM, after doing some research it appears there is not a fully functional ROM available yet. However, if you are willing to give up a feature or two, you may be able to get a stable release running on your phone. Please refer to the xda wiki page specifically for the ICS development status on the Motorola Defy for more information about the project.

Would rooting my phone prevent me from using device protection features

It appears my comment was incorrect, once you Enable OEM Unlocking in developer options, you have disabled Factory Reset Protection completely.

  then OEM Unlocking.
   - Source

And no, once you have unlocked the bootloader (required to root) you can not re-enable this switch, it is greyed out and non-functional, unless you relock the bootloader which cannot be done without have a completely stock image installed, meaning no root, custom recovery, or other modifications to the device.


What is the meaning of "Unfortunately, the process android.process.media has stopped."

android.process.media is a common issue which can occur anytime and is caused mainly because of two applications, the Download Manager and the Media Storage.

try the following

Go to Settings > Applications > Manage Applications and make sure to look under the ‘all’ tab. Scroll down and find Google Services Framework and clear the cache and data for this one.
After doing that, scroll down and find Google Play. Tap on it and clear cache+data for this one too.
Now press the back button and choose Google Services Framework from all apps > Force stop > Clear cache > OK
Now open Google Play from you app drawer and when given an error, click OK.
Turn off your device by holding the power button and clicking on Shut down/ Reboot


sync android calendar (tasks) with calendar from PC

As you're after a plain Android <-> Windows solution, apart from different hosted solutions, MyPhoneExplorer might also be worth consideration. AFAIK it can sync your Android calender with different Windows solutions, especially Outlook, but IMHO also others. According to its description, this also includes – tada! – even your favorite Windows calendar:

  MyPhoneExplorer is a powerful phone management software for your Desktop PC. Some features:

  sync your phone with Outlook, Thunderbird, Sunbird, Lotus Notes, Tobit David, Windows Contacts, Windows Calendar,...
  manage your SMS, Calllists, Apps, Files, handle Calls, create backups...
  Connection via WiFi, USB-Cable or Bluetooth.

  This is the client which is needed for phone, you'll need also the desktop-software which can be downloaded at www.fjsoft.at.

(emphasis mine)

I think this will suit you best. MyPhoneExplorer is said to be a real good solution (as a side-effect, it even helps you with backups, and other means of managing your Android device). Not being a Windows user, I cannot speak from my own experience, though – but a Playstore-rating of 4.6 with ~20k votes should mean something, too :)


I actually had the same problem recently. It might be one of those, "It's a feature, not a bug" things. I had my Dropbox associated with my desktop computer. When I deleted a folder of pictures from my computer, it deleted those pictures from my dropbox all together.

This seems like quite a mistake, as deleting a local copy should not delete the remote copy on Dropbox.

You should be able to restore your deletions on the Dropbox website. I was able to recover everything I deleted. It doesn't actually delete your items for a long time (scary).


Take the image of the phone that's working by the following code

First find out the dev block of the system partition

  cat /proc/mounts

Search for the system partitions and note down the corresponding /dev/block/ partition
For example for my phone it is /dev/block/mmcblk0p12
Now make the exact copy of the partition using dd command

  dd if=/dev/block/***** of=/sdcard/system.img

Copy this system.img from your phone to PC
Connect your other phone in fastboot mode

Why is the stock Android dialer app incompatible with my Samsung J7 2017?

Some apps are only set to install on the phones they are designed for. The workaround is you can get it from apkmirror.com and install it. It should work on your Samsung. I installed it from there last year on my LG V20 and it worked fine.


Google Play Services and Play Store crashing

Ouch...

So, I'm unclear on what exactly you meant by "took a backup"...

This sounds like a Google Play Services mismatch - either mismatched with the Android version you're running or different app versions installed.

I'm gonna need more info to troubleshoot it, but just a couple shots in the dark here:

Play Service and Store don't like being messed around with. Just, in general. That's why they're usually installed via a recovery zip file.
If you moved the latest version of Play Store (vending.apk) and Play Services (gms.apk) from userspace to /system/app, that's most likely what caused this.
Hopefully, you backed up the versions in /system/app. The Play apps usually rely on library files (.so files), which are sometimes updated in userspace. You're probably getting a mismatch between those.

If you backed up the previous copies, recovering from this is simple. Just restore the backups. If you didn't, this may be more difficult. What device are you on? Also, what Android version, and are you running stock or a custom ROM? (if you don't know the answer, you're probably on stock)


Way to send a barcode via SMS with as little user interaction as possible

barsent

....................................Weird name, I know right!

  barsent is a simple and free app that lets you set a predefined number in the
  options and then any subsequent BarCode scan results will be sent to
  that number instantly without any prompts.

The barcode reader by ZXing Team is however required for this app.

Get it here!

CLICK HERE TO DOWNLOAD THE BARSENT APK (not available on market)

Remember to turn on "install from unknown sources" in your options!

Btw, the app is made by me when I got some spare time and I thought while it may be too simple, it could be helpful to a few people. Your question inspired me to make such an app (lol I know im such a sucker for bounties) ; anyway, it was fun getting this done in the MIT's App-Inventor

The app is not well tested because I did not have much time. If you find bugs or want to request for a feature, maybe we can do it over the chat here on android stack exchange or via email preferably. Comments are probably not the right way.

A few things I'd like to say

Its simple and will always be free
If its slow or crashing, I might not be able to do much really since its made using appinventor, do tell if those things happen though.
If you don't like this, you can modify or build your own or ask me for features. Also, there could be potentially some apps in the market that does the same in a better way. I simply made this app for fun.
I don't know if I can support app2sd or crunch the size of the app.. its just appinventor and I didn't include any fancy media into this app.
There are no obtrusive ads, background services or airpush junk
Permissions are exaggerated by the appinventor I guess
Don't hold me responsible for anything
If you like this, you can upvote this, share it using the small and cute buttons to the left of this post.
Oh and after installing the app, I recommend scanning the barcode that's above in this post using the app. ;)
Screen Shots.. maybe later but the app's really ugly in terms of looks. :D
Exclusively for the stack exchange community! That's why I am posting here!


Remove thousands separator in Calculator app of Samsung Galaxy S2

No, there doesn't seem to be any configuration to remove the digit grouping on the stock calculator app.

If you are not particular about using that very app, you can try out some free calculator apps from the market. I tried RealCalc Scientific Calculator, and it's got an option in its Settings to remove digit grouping.


How do I change the call from my left earphone to right?

Go to Settings --> Accessibility. Then tap Hearing. Towards the bottom, you will find an option for Mono Output, switch that ON. Then you can drop the earphone from one ear.

There is also a left-right sound balance. You can shift the slider to the ear you prefer.

Here is a guide to using the hearing accessibility settings on your phone:

How to cast Youtube video, but keep sound in headset?

Robert's answer in comment:

When casting an online video your smartphone simply tells your TV
which web address to play. The audio is never processed by your
smartphone. Therefore it can not be played by the smartphone. Better
connect the headset to your TV.

So not possible the asked feature, but you need to connect your headset to your TV.


How does my tablet know when I open the cover?

Your device will have a little magnetic sensor hidden under the display that can trigger the display to turn on.

A small magnet lies embedded directly under the surface of the smart cover and lines up with the corresponding spot on the device. The device detects the removal of this magnet when opening the cover and turns the screen on, and can also put the device into sleep mode when the cover closes.


play.google.com and Google Play app out of sync

It may be the link to the Play store was lost. I think if you install an app from, say, the amazon app store, Google Play will not be able to update or uninstall it, as the link is gone. Similarly, restoring an app from a previous rom backup may not create that link.

Titanium Backup can recreate the links (the free version can can't do this). Or you could uninstall the app and try installing it fresh from Google Play.


Is it possible to have a higher level of lock-screen security only on boot up?

You can encrypt your phone and it then will ask for a pin each time you boot your phone

ADB backup archives are a "all or nothing" solution when it comes to restore – which is what the "unsafe warning" is about. Considering your circumstances, here are a few points to consider:

do one "full backup" excluding your system apps cannot hurt, so you could restore that as-is. Note, hoever, that this most likely also excludes data of system apps, which might include APNs, contacts, calendars, etc.
use e.g. Helium Backup (no root required) to create ADB compatible backups of all your apps separately, so you can restore them separately. This can of course also be done on the command line (specifying the package names), but this app makes it much more comfortable.
Create a full ADB backup nevertheless, including everything (except -shared, as data from your (internal) SDCard can be copied on file-level using any file manager). Though you probably might not wish to directly restore it, you might still have use for it

Considering you're after rooting in the first place, here's the background for my recommendations:

If you succeed rooting your device, and have no side effects, all the above backups just gave you a "good feeling", and you have no current need for them. But hey, it didn't hurt; could well be one of the following things happened:
If you succeeded rooting, but had to factory-reset the device due to some side-effects, you could either use Helium (or adb restore) to restore selected apps from their separate archives, or use adb restore to restore all of your user-space-apps in one run. But you could also use Titanium Backup to extract selected apps/data from the complete backup, and also restore some system data that way.
If rooting failed, and you have to factory-reset your device, you at least can restore your user-space-apps and their data from that archive, or chose to only restore selected apps as described above.

As for the size of 22 MB: That could be fine, or could be too small – depending on what apps you've installed, and how much data they have; there are no absolutes for "user-apps-only" backups (except of course for 0 byte files when you have at least 1 app installed).


Can I manually reattempt restoring SMS messages from backup?

I'll skip the basic parts where you know that a factory reset wipes the phone and address to what I believe to be the core of the question -

  Is there some manual way for me to reattempt the restore from backup?

I'm not totally sure if you ended up with an upgraded version of Android (from what version to what) or if you 'chose to restore everything from backup'.
Depending on the details here you could face the issue where you, even if you have a backup of the SMS database it may not be directly usable by a different Android version.

The SMSes are stored in a sqlite database, typically a file called
mmssms.db. On my phone it is located at the following location (a typical one) - shown for me by this command on my Android;

find / -iname '*sms*.db' 2&>/dev/null
/data/data/com.google.android.gms/databases/icing_mmssms.db
/data/data/com.google.android.gms/databases/ipa_mmssms.db
/data/user/11/com.google.android.gms/databases/icing_mmssms.db
/data/user/11/com.google.android.gms/databases/ipa_mmssms.db
/data/user_de/0/com.android.providers.telephony/databases/mmssms.db
/data/user_de/11/com.android.providers.telephony/databases/mmssms.db
1|herolte:/data #

The key file here is

/data/user_de/0/com.android.providers.telephony/databases/mmssms.db

Even if you may not be able to use this db on your (possibly newer/different) Android, you can always see/extract the messages inside using a tool on a PC for instance. Search for 'sqlite browser'.
You will have to decide if you need assistance with handling the SQL tables/format, but it should be easy enough to browse read-only.
(And, of course, always back up stuff before trying out changes.) That you do have a backup is very positive.

You could also (less manually) search for tools/apps that possibly not only backs up the SMS'es, but perhaps are able to restore from your backup. Also in this case case may the key file in question be the file mentioned above.


How to display the on screen keyboard when Bluetooth keyboard is connected

I was testing ways to toggle the on-screen keyboard. In Android 4.2.2 on a Nexus 7 I had to go through the following steps to toggle the on-screen keyboard from the tablet while a Bluetooth keyboard is connected:

To activate the "Choose Input Method" notification you need to have multiple keyboards available. On a stock Nexus 7 you can go into Settings then "Language and Input". Under "Keyboard & Input Methods" check the box next to another keyboard like the "iWnn IME Emoji input" or "Google Pinyin Input".
(Optional) If you don't have any other keyboards available you can install a 3rd party keyboard from the Play Store like the NullKeyboard or AnySoftKeyboard. Back in the Language and Input Settings check the checkbox next to the 3rd party keyboard you installed. Read the warning message and click OK if you agree.
Go to any text input box
A new notification appears in your notification bar (top left) labeled "Choose Input Method", tap the notification (not Select Keyboard Layout)
The first item in the "Choose Input Method" popup is "Hardware" with an on/off slider, choose "Off"
Use the radio buttons below to choose your software keyboard (I chose the Google Keyboard)
Tap the back button and the on-screen keyboard appears.
The Bluetooth keyboard is still functional.


Which camera gives more accurate image, the front or the back camera?

Resolution governs quality of pictures

The back camera invariably is of higher resolution and is meant for better quality. Typical resolution is upwards of 10 Megapixels
Front camera is not meant for high resolution and was intended for visiting the image during video chats. With demand for better quality (including "selfies", it is now typically upwards of 2 megapixels and in recent phones 5 or more. Dark images as reported is less for to quality of  camera but more to do with subject focus and lighting conditions

Edit

OPs concern is more about "distortion". To reduce distortion

Take the snap at arms length, picture would be smaller but less distortion
Reduce aspect ratio (if default is higher) to 4:3
Keeping the subject and camera at same level and experiment with aligning your face to the top/bottom edge of photo to see if it reduces distortion
Try an app like Cameringo, which augments photo taking capabilities considerably and adding effects (I use the pro version of this but more for rear camera shots and both trial and pro versions are good). This may also help tackle the rear camera issues faced


Google Play Services has to be installed as a system application. Assuming you have properly uninstalled that application, you have to copy the .apk file back to where it should be (probably /system/app or /system/priv-app).

To that No Carrier thing: This just means that your device didn't send Google any Information about the carrier that you have and that you should use the normal, non carrier-specific store (There are different stores with some extra applications/different listings for specific countries and even carriers).


Try going to 'Settings' and then go to apps/applications tab then go to 'all apps' you can then select the apps you do not require and then select uninstall, if you had the app already but it just updated it, it will just remove the update, but have factory version. Hope this helps.


Ultra STAMINA mode bug on Sony Xperia Z3?

Try charging your phone to its max and try again. This should work, do not turn on your phone until it shows that it is 100% charged. Reboot your phone and disable Ultra STAMINA mode, everything should be fine.

If your battery is less than 15%, Ultra STAMINA mode does not allow flash, camera location, 4G which requires maximum power and drain the battery.

Charge your battery to max
Reboot it

It's certainly possible to remote-brick a phone.  In fact, you might be able to use Tasker in conjunction with Mobile Odin or similar to remotely softbrick a Samsung device by flashing bad firmware after a text message, or something.  Of course these devices are also easy to unbrick; to brick them more permanently you'd need to flash a bad bootloader.  Chainfire has said that Mobile Odin can but won't flash bootloaders, so perhaps it could just be modified.

Bad bootloaders can be fixed sometimes if you have the appropriate hardware, but I doubt any petty thief would have it.  Most won't be able to fix a softbrick either.

Any app can be disabled, pretty easily too if you know what you're doing.

Importantly, though, I wouldn't do this.  All it does is guarantee that you can't get the phone back (you can't track it anymore) or that if you get it back, it won't work.  You should just install tracking software instead.  Remote bricking won't deter a thief who doesn't know about it, and while I see the revenge aspect it's not as good as catching them!


Can't recover Whatsapp messages on new phone from Bluestacks

First you have to change your whatsapp number in bluestacks and backup your messages to google drive. Then you have to install that number on mobile and follow the steps. Through that you can see a backup recovery option on whatsapp. Give your gmail and download the backup to mobile. Enjoy as like in bluestacks android emulator.


Is it possible to re-install Android OS When the OS is practically useless

Short answer is yes!
Long answer:
you can Flash* Android "Stock Rom" for almost any type of android devices, even if the old one isn't loading at all.
as long as the hardware doesn't have any problems
but there is some problems
1. To find the stock Rom:
you will find it with a little search depending on device manufacture
2. To flash it without breaking your device:
this process can be very risky and highly depend on device type
3. you will lose your warranty
safest way is to find a near service center to do it for you
but you can find very useful stuff here:
https://forum.xda-developers.com/


Odin error : NAND Write Start!! FAIL! (Auth) can't flash stock rom SM-G530H

I'm pretty sure you're in Recovery mode. Put your device in Download mode (turn your device off, press and hold volume down and home buttons, then press and hold the power button until the download warning appears, then volume up to continue, connect USB and run Odin) to flash with Odin.

Putting your phone in Recovery mode is done the same way except volume up is pressed with the home key instead of volume down.


What are the main differences between Android and iPhone implementations of application multitasking?

This is not an answer to your question, but it's worth clarifying that both operating systems are fully multitasking [1] under the hood (insofar as they can and do run multiple processes).

Your question is clearly about application-level multitasking ("can I leave one application running while using another?"), which is a relatively new use of the term, and isn't always well-defined, even if it does have some obvious examples (like listening to Pandora while reading email).  Specifically, many applications don't need to run in the background in order to present themselves to the user as if they had never stopped running, so long as they save/restore their state.  Applications which must perform periodic operations (like checking mail or popping up alarms) don't need to run continuously in the background either; they can invoked occasionally by the OS.  The big issue is usually applications which need constant CPU while in the background, like Pandora.

In general, Apple has worked much harder to discourage or prevent continuously-running background applications, whereas Android seems more open to it.  But they are converging, as Apple allows apps like Pandora to run in the background and Android provides richer tools to discourage needless background tasks when polling or saved state would suffice.

Does the Android emulator generate some sort of log file I can access if it crashes?

kernel panic

When a kernel panic occurs all user space programs are immediately stopped, preventing a user from detecting the cause of the panic: logcat; dmesg and /proc/kmsg will do you no good.

You can still check the /data/dontpanic/ folder for any files present, like:

apanic_console or apanic_threads

kernel boot

Method of logging kernel messages:

invoke "dmesg":

See it as it happens:

# adb shell dmesg

Direct to a file on your sdcard and see it later

# adb shell dmesg >/mnt/sdcard/dmesg.txt

"tail" the kernel if "syslogd" and /var are available:

# adb shell cat /proc/kmsg

dump the kernel file /proc/kmsg:

# adb shell cat /proc/kmsg

Note: You may need to issue su to gain permissions over some files if you're stuck with an error message. Alternatively, removing shell from the command will execute it on the computer side, not on the phone.

is CPU virtualization needed to run Android Virtual Device?

While running AVD I got the error:

[2015-05-04 23:02:01 - TESTapplication] Launching a new emulator with Virtual Device 'TEST_5.1_5.1.1'
[2015-05-04 23:02:01 - Emulator] emulator: ERROR: x86 emulation currently requires hardware acceleration!
[2015-05-04 23:02:01 - Emulator] Please ensure Intel HAXM is properly installed and usable.
[2015-05-04 23:02:01 - Emulator] CPU acceleration status: HAX kernel module is not installed!

and I got the thread which talk about this error.

https://stackoverflow.com/questions/27720064/hax-kernel-module-is-not-installed

so Conclusion is my Intel Core to Duo T6400 CPU do not support hardware virtualization and will not be able to run AVD. I need to get new Laptop to get this CPU function and AVD running.


LogCat shows exception in SyncProcessorQueue every 5 seconds

As per this thread, it's related to Google Currents. Either disable the automatic syncing feature of Currents or uninstall Currents completely to get rid of this error.

I don't think it's a "bad" error though and should not cause any other problems (such as battery drain, etc.)


Not a solution for this problems specifically, but have you tried using StackMobile? It's a mobile-friendly ubersite for all Stack Exchange sites.


What does 'extract exception, please check files' mean?

The most likely explanation is that the compressed file is corrupt. Are you trying to uncompress a rar file, or a standard zip file? rar extraction is only supported with certain processors.

The easiest way to tell, is to try and extract the same zip file on a computer, and see what it says.


Can I update Motorola Moto E to Android Lollipop 5.1.1?

The phone runs 4.4 and then requires Motorola Update Services from Google Play to update to 5.1. NOT 5.1.1. Wasted cash :(


Do "unlocked" phones come pre-unlocked or just the ability to be unlocked?

They aren't related at all
Unlocked phones refer to phones that aren't bound to any carrier.
It looks like you are mixing this up with bootloader-lock, whose tag wiki says

Some bootloaders are locked by the manufactures to prevent the phones from booting unofficial firmware images.

(Read the wiki and linked questions for more information)
These two are totally independent and as a security measure practically all mobile devices are shipped with boot loader locked while they may be carrier locked /carrier unlocked. For instance, in India we don't have the concept of carrier locking (barring a negligible few cases) and therefore all phones are carrier unlocked, while they are boot loader locked. How easy or difficult is it to unlock boot loader depends on the measures taken by the OEM and again has nothing to with carrier lock/unlock (carriers often make it more complicated)


Fastest way to transfer small files to PC

I use BitTorrent Sync a cross platform sync program using the P2P protocol. The files will only exist on your devices unless you set up a cloud based service to watch your file(s)/folder(s). Send & receive files of any size on any network, encrypted & visible to anyone whom you share the private key(s).


Want to sync data (music) to sdcard on Android 7.0

If you really want to keep the entire directory (and possibly its sub-directories) in sync, so that their content is "mirrored", FolderSync would be a good candidate. It's an app running on your Android device that can communicate with a plethora of protocols:

FolderSync Screenshots (click images for larger variants)

As you can see in the first screenshot, it not only supports many clouds and FTP, but also Samba/CIFS (Windows PC, second from bottom). SSH can be used as well (that's how I use it with my Linux machines). FolderSync also allows you to schedule syncs, even limit that to when you're connected to your home WiFi. The paid version also has tasker support.

I'm not affiliated with the product or company, but I'm using the paid version happily for years on multiple devices :)


How do I diagnose a WiFi Error when the phone just reports "Unknown"?

Try to search for Google the appropriate Kernel for 2.3.6 (presumably you are running on 4.5.141 firmware). Then flash it. When I say "flash", I mean a flash by CWM. Good luck.


If your phone is rooted you can use Stubborn Trojan Killer.


Hard Reset to Factory Settings without USB access

2) Enter your email id and password(which one used in asus zenpad z300c)
3) If you have multiple device with same id then selected Asus zenpad z300c carefully.
4) If only one device is register then skip step 3. And In left hand side select option ERASE DEVICE .
5) Might be Google will confirm password again. So enter it again.
6) Done.
7) Your device is factory reset.

note **Your device Asus Zenpad z300c need to connected to internet to perform this operation prefer wifi connection **
Good Luck.....

Please update it is successful or not.


Can not uninstall an app(hi app lock) which has device administrator rights

Unable to boot Galaxy S - only see a picture of phone -> "triangle with an exclamation point" -> computer

Now, the only option you've left is to Flash your ROM. Flash any one of OFFICIAL firmware from below:

Gingerbread 2.3.5 XFJVA
Gingerbread 2.3.5 XXJVT

Follow the links & do EXACTLY what it says. It'll take less that half an hour. Just, do it.. Nothing more!

Don't do any experiment before you boot your device. Plus, don't follow any non-matured instructions from forums etc.


How do I export my Samsung Galaxy 551 contacts to my Samsung Galaxy S2?

If you want to do it without going via Google, just follow these steps. To make it easier for others to follow, I refer to your Samsung Galaxy 551 as "old phone", and the Samsung Galaxy S2 as "new phone":

On the old phone:

Open the Contacts app
Tap the "menu" button to bring up its extra menu
Select "Export/Import", and chose to export your contacts to SDCard
Pick the created file (it's most likely named 0001.vcf, or at least similar – .vcf stands for "VCard File") and copy it to your PC

On the new phone:

Copy the 0001.vcf from your PC to the SDCard
Follow steps 1-3 from above, but in step 3 this time chose to import the VCard File
Select the VCard file from your SDCard, and have it imported

You're done – all contacts from your "old phone" should now be on the "new phone". Additionally, you've got a backup on your PC which you can easily import to other PC applications as well: most contact handling applications should understand this format.


Samsung galaxy tab2 P3100 "android.process.media" stopped issue?

hay it's a simple problem to encounter, go to settings reset the system don't forget to backup your important data before doing so.


Yes.

Even stock ROMs have a feature named Scheduled Power-On.

Phones have a built-in battery to allow RTC (real time clock) to run while the device is powered off, and it's the base that scheduled power-on is designed.

Here's Settings -> Advanced -> Scheduled Power On/Off on my phone (OnePlus 5, Stock 7.1.1)

Delete constrained 2048px images and upload "high quality" < 16MP photos

Right, so I think I've roughly worked out the process, please feel free to comment, or correct if you find this is inaccurate:

It appears that deleting from google photos (at least on my Galaxy S5, and Tab 3) does not delete the original. My photos are held on the external SD card on both devices. Not sure whether this matters. Having deleted the photos on the web, I can still see the originals in my camera folder. I'd be extremely cautious attempting this test on a stock Android phone as it may be different.

What deleting does do, is it seems to retain the record of the file on their server. So even when I cleared app data after deleting the photos, and backing up again, the photos did not back up.

Now what I have found useful, is that despite this shortcoming on Android (may be a workaround somehow, perhaps going a step further and deleting the app?), I can import the previously deleted photos onto a computer, and upload via the Photo Backup service, or manually via the web app.

I think it's theoretically plausible that I could delete all my smaller photos uploaded previously and re-upload without issue, but I think I'm going to do them slowly and carefully.

I wish Google would provide a bit more insight into how Photos checks that a photo has been previously uploaded (and perhaps deleted) but I hope this is helpful.


"USB Debugging" mode not visible, Samsung Galaxy Note II

Apologise for my ignorance as I dont have a Galaxy Note II but since you have the SAMSUNG Android ADB Interface I am presuming when you run command (and get this from google too)

adb.exe devices

Do you at least see a Serial Number??

I had a similar issue with my Nexus 5 and noticed I too have the same drivers however for my computer to connect to the device I had to make sure my device is:

NOT in a Locked State (meaning the phone is not on the lock screen)
Debugging is enabled (You already have)
And accept the adb connection physically on the phone (just do the adb connection and it'll prompt your device for privileges.)

EDITED - 01/08/2014


Use the free app ics Databridge. It works perfectly. The size is just 25kB.


Make sure your network/gps location is correct, then clear app data.

I had a similar issue with Google Maps (hotel price in foreign currency) after international travel.


unable to remove google play store search history

Follow this instructions listed here.  On Android:

  Tip: If you want to delete your recent searches under the search box, touch and hold the search you want to delete > OK. The search will be deleted from the Google app and your Web & App Activity.

  Delete items one at a time

  Visit your Web & App Activity page.
  Check the box next to the items you want to remove.
  Touch Remove items at the top of the page.

  Delete multiple

  Visit your Web & App Activity page.
  In the top right corner of the page, touch Options > Remove items.
  Choose the time period for which you want to delete your history. (To remove all items, select The beginning of time).
  Touch Remove.

  Note: If you turned on the option to include history from Chrome and other apps in your Web & App Activity, visit the additional Web & App Activity page to see that information. If you only want to remove additional Web & App Activity from a certain device, choose that device in the "Remove items" dropdown menu.


get information from devices which connect to same wifi hot spot

There's an app on Play Store called Fing that's probably close to what you want. You don't even need to be the host, it detects all devices on your network.


Is it possible to force an app to use cellular data instead of WiFi?

As far as I know, android won't use cellular data at all when wifi is enabled. On a regular machine I'd create routes for whatsapp to use the celular interface, and have a default route using the wifi interface.

One solutio might be to use a VPN server at home, and connect to that on your phone. If you run OpenVPN op tcp port 443, then you'll probably successfully evade the firewall. The downside: it can eat battery like crazy (at least, it did when I tried).


Why my apps are getting auto-updated despite "Don't auto-update apps" checked?

Now apps have separate auto-update option in Play store. So disable it, uncheck it.


Choose your go keyboard app. Then themes. In the top right corner there is a icon that looks like a gallery its right about the word LOCAL. once you choose that it says customize theme.. you can from there choose your portrait or landscape background and customize it.. To choose your own photo you will need to have the photo saved in your gallery of pictures.

I tried flashing SuperSU .zip file and after a few attempts it worked. No idea what was the problem, but it is fixed now.


Is Google Allo supposed to capable of being the default SMS app?

It's not possible - it's universally the case:

  First off, Allo isn't a Hangouts replacement. You can't set the messaging service as the default SMS client on your phone. It does offer the ability to message a contact that doesn't have Allo installed through Play Services, but that's about it. You can also talk to contacts over SMS, with the message itself routed through Google's servers, but Allo isn't an SMS service by design. In this regard, it has more similarities to WhatsApp than iMessage.

Emphasis added by me.

Note: It seems that Allo is going to be discontinued.


I'm definitely not a expert on this but hopefully I can be a little help.

Usually the devices measure the voltage of the battery.
When a battery is discharged it gradually degreases it voltage level.
When the voltage level is dropped below a certain point the hardware doesn't work anymore.
This is one of the reasons why the older ipod/ipad/iphone devices didnt shut down at 0% battery but a lot earlier (If I remember correctly my old ipod touch would shut down around 11%.

EEVblog made a great video about debunking a product that claims that it can extend battery life of electronic products EEvblog Video. Too debunk the product he gives a lot of information about what happens when battery discharges and about when electronic devices shut down.

Hopefully can this information help you a little bit with your project.


How to import my Contact from google contact to Coolpad Android Phone

If you visit https://contacts.google.com (Contacts Preview) you cannot export contacts. You need to vist the old Google Contacts website i.e. https://www.google.com/contacts and export all your contacts to restore in your phone.

Visit the old Google Contacts website
Click More > Export
select All contacts radio button to export all your contacts
Select vCard format to export your contact as a single .vcf file
Now move this .vcf file to your phone and import the .vcf file to your phone using the inbuilt Contacts app.


How can I control media volume from a 3-button in-line remote?

You can use a headset controller app from the playstore (e.g. Jays or Philips Headset or HeadsetButton Controller) to use the "middle button" for that. Might take a few tries to find the correct app (if one doesn't work fine, try another -- I did the same and finally found one working perfectly, see my answer here). I'm not sure if they affect the other two buttons at all, or if you even could configure them -- but they allow me (having a headset with a single button) to perfom all the most necessary functions like play/pause, skip, vol+ and vol- with a single button.


You said that when you plug in the earphones the music pauses and when you resume it starts playing on the phone speaker.
That is because the connection between your earphones and the headphone jack in your mobile isn't established.
The main reasons behind this is maybe there is some dirt in the headphone jack. You can remove it with an earbud.
In some other cases usually the headphone jack is damaged and needs to be replaced. I have this same issue and I didn't find any solution to this. So I bought a pair of bluetooth headphones.


Carbon backup discovery issues with Nexus 7

As it turned out, all the other apps had their corresponding .json file missing. Not a big deal: As badp's answer shows, one can simply use adb restore to restore the backups. But as not everybody might have the SDK (or even a minimal ADB) installed (or even a computer available -- one might be on a journey), my answer will take a different approach.
What we need
First, you will need to make a backup of some app, to get a working .json file. As the question states, there was such one from the Adobe Reader. To visualize it for you, this is what the corresponding file (com.adobe.reader.json) looks like:
{
  "enabled":true,"system":false,"flags":10010180,"packageName":"com.adobe.reader",
  "versionCode":73784,"label":"Adobe Reader","versionName":"10.5.2","locked":false,
  "date":1367072517125,"apk":false,"backup":true
}

You will also need:

a file manager
an editor

Of course, you could also perform the steps below from your Linux computer; using a different OS, take care for the file's encoding and line breaks.
What we do
I pick an example app here: Kindle for Android. In the question's screenshots, it's listed close to the Adobe Reader as com.amazon.kindle. For your apps, just pick the corresponding values based on this example:

copy com.adobe.reader/com.adobe.reader.json to com.amazon.kindle/com.amazon.kindle.json
open com.amazon.kindle/com.amazon.kindle.json with an editor

replace com.adobe.reader by com.amazon.kindle for packageName
replace Adobe Reader by Kindle for Android for label (actually, you can put anything here -- but might prefer to know what you've got :)
optionally, replace the versionName accordingly (it will work without)
save the file

I'm not sure what versionCode or flags stand for, so we better don't touch those. We also can safely ignore the rest:

"enabled"="true" should mean "this app is enabled (i.e. not frozen)"
"system"="false": It's no system app (matches: Kindle is no system app)
"locked"="false": This app is not "protected"
"date" obviously holds a Unix timestamp (most likely that of the backup)
"apk"="false": Ah, data only (Cabon's default is to not include the .apk with the backup, to speed things up)
"backup"="true": Is this a joke? What else could it be?

Now, first let's see whether Carbon accepts our trick. If it correctly lists up Kindle for Android as being available for a restore, you might want to repeat above steps for your other backups as well.


How to open winmail.dat file email attachment?

Microsofts Outlook e-mail program sometimes sends e-mail attachments as "Transport Neutral Encapsulation Format" (TNEF). This attachment is usually named "WINMAIL.DAT".

You should install the Winmail.dat Opener(1.7mb) or Free Winmail Viewer(6.9mb) app from the play-store. Opening the file will reveal you multiple files packed into it just like a zip file.

  How to open a winmail.dat file?

  Select Winmail.dat Opener from the context menu of the winmail.dat attachment.
  Start Winmail.dat Opener and use the built-in file dialog to select a previously saved winmail.dat file. Once you are at the
  contained files list, you can long click a file to open it or select
  files and click the "save" icon from the action bar to save all
  selected files to the sdcard. All files will be saved to a directory
  called "winmaildatopener".
  After successful export of a file to this
  directoy an open file dialog will enable you to start further actions,
  like open, share on the exported files.


Is it possible for a device to consume more power than it is wall-charging?

Yes, it's definitely possible.  Most USB chargers are fairly limited in their output and devices like tablets are not really designed to be used while charging, unlike laptops.  You'd think it would be OK to simply sit and remain on while charging and unused, but perhaps the Nexus 7 does not have very good power management.  You might want to look at having sync pause while the device's screen is off.

If you want to crunch the numbers and verify what's happening, take a look at my answer here about the PS Vita.  If you get the specs/numbers for the Nexus 7 and its charger you could do a similar analysis to see whether the power use is exceeding the charger's output.

Is there a way to trigger hover behavior in the Chrome Beta browser?

One way to trigger the hover on links is to long-press the link, wait for the menu to appear, and the press the back button to cancel the menu. This also works in some other browsers.

Note that this doesn't work on all links. Just tried on the example you mentioned, doesn't work, probably because there's a slight delay between the onMouseOver event and showing the menu. But on other pages, where it's a simple onMouseOver trigger this method works.


Bluetooth keyboard pairs but does not appear as an input device?

Found a possible solution from Android Central questions give it a shot.

Specifically, this post says to do the following:

  When pairing the keyboard with your device, it will prompt you to
  enter a pin and say "try 0000 or 1234." You need to:

  Step 1) enter "0000" on your android device (tablet or phone
  keyboard) Step 2) hit "okay" Step 3) type "0000" and hit enter
  on your BLUETOOTH keyboard


Wifi won't turn on after rooting, still won't turn on after factory reset

There can be two causes:

Hardware failure. Unlikely, but a possibility.

Each device has multiple sub-models, and each sub-model has multiple roms. You need to be sure you're installing the Rom meant for your exact device model, even if you are re-installing a Stock Rom. If you do install a rom not meant for your device, you often face issues like these.
The solution for this is to first confirm your exact device model:

Boot into your device's bootloader and look up the device version/model.
Open the download page of the Rom you installed
Download the version specific to your model
Install the Rom the usual way, but be sure to do full wipe/clean of all partitions first from the Recovery.


Does OnePlus 2 "DUAL SIM 4G" support dual 4G?

No, OnePlus 2 is not any different.

In fact, users on the forum report that the dual SIM functionality apparently requires the presence of a 2G GSM network.

https://forums.oneplus.net/threads/dual-lte.328953/page-2

  I have the OnePlus 2 (A2005) and am using it in Canada. SIM 1 on Telus (4G/LTE) and SIM 2 on Wind. When I want to use data on Wind, it switches SIM1 down to 2G. Except neither Telus nor Wind has 2G. So when I choose either one for data, it shuts down the other one completely due to lack of 2G. It doesn't just step it down to 3G. This makes the phone pointless for me. Due to their advertising I was hoping that both would be 4G simultaneously, not 4G on one and 2G on the other.

To summarise:

You can connect to any network from any SIM (e.g., can make either SIM a primary one)
The non-primary SIM can only connect to a 2G GSM network
If your non-primary operator lacks a 2G GSM network (which are being shutdown worldwide, and some GSMA operators never had any to start with), the non-primary SIM cannot connect to UMTS or LTE, and will thus be getting no signal at all


How do I recover contact from android phone(one plus one) after touchscreen stopped working?

If only touch stopped working and screen is properly visible then you could try the USB OTG with keyboard and mouse to go to contacts app and export your contact or sync them to google account


copying music, pictures and movies from a galaxy s 4g to the pc

It would be really helpful if you mention which operating system your PC is running.

On Windows 7 and above, you simply need to connect the phone to your PC using a USB-MiniUSB cable. You should then be able to access the files on the phone via Windows Explorer. You can then use Windows Explorer to copy files to and from your PC.

On Windows XP and below, you will need to either:
a) download and install Samsung KIES

b) download and install the Samsung Mobile Device USB Drivers

Once the drivers/software are installed, follow the same steps as for a Windows 7+ PC.


Is there any downsides to rooting the tab s?

I don't see any harm in rooting unless you brick your tab.

Also, if your tablet in under warranty you will void the warranty on rooting the tab.


I found myself needing to do just that. Here's how I managed to get the job done.

First, I create a raw contact by doing:

adb shell content insert --uri content://com.android.contacts/raw_contacts --bind account_type:s:SOME_ACCOUNT_TYPE --bind account_name:s:MY_ACCOUNT_NAME

This will effectively create a new Contact (you will be able to see a new contact in Android's Contact app) but with no extra information (phone, name, email, etc...)

Next, I add name information to the recently created contact:

adb shell content insert --uri content://com.android.contacts/data --bind raw_contact_id:i:1 --bind mimetype:s:vnd.android.cursor.item/name --bind data1:s:MY_CONTACT_NAME

After this, you will notice how the new contact now has a display name in Android's Contacts app.

Notice how, in this case, I need to pass the raw_contact_id of the contact I'm trying to set the name for. I used 1 just as an example.

You can query this information by checking the data from all contacts:

adb shell content query --uri content://com.android.contacts/raw_contacts

Or if you want the straight anwser:

adb shell content query --uri content://com.android.contacts/raw_contacts --projection _id --where "account_name=\'MY_ACCOUNT_NAME\'"

Finally, I add the phone information:

adb shell content insert --uri content://com.android.contacts/data --bind raw_contact_id:i:1 --bind mimetype:s:vnd.android.cursor.item/phone_v2 --bind data1:s:MY_PHONE_NUMBER --bind data2:s:SOME_PHONE_TYPE --bind data3:s:SOME_LABEL

And we are done! You can check Android's Contacts app and see a contact with a display name (MY_CONTACT_NAME) and a phone number (MY_PHONE_NUMBER).
There's plenty more information you can add but I guess this covers your needs or at least gives you a good idea of how to continue.

Bonus: I know it isn't exactly on topic but you can even run a little program to automat this using UiAutomator. For example:

InstrumentationRegistry.getInstrumentation().getUiAutomation().executeShellCommand("content query --uri content://com.android.contacts/raw_contacts");


Why is the Verizon Cloud app generating Instabug text files in my File Manager Documents folder every time I start up my phone?

Well, it appears that the culprit app is the VERIZON CLOUD APP.

I went to the Instabug website. I was thinking of actually sending them a message because the path shows their software name. But, I found this article. It appears that Verizon uses Instabug, and the person interviewed for the article is Mohammad Hariri, DMTS for Verizon’s Communications and Cloud division. So, I thought I would try disabling the Verizon Cloud and and IT WORKED!!! I have turned my phone on and off three times. I don't get the text files!

https://instabug.com/customers/verizon

So, now the question is: How can someone in charge of that Verizon Cloud app look at this issue?

Extra: I reinstalled the Verizon Cloud and instantly got a text message in that Documents folder.


both solutions mentioned by @Izzy and @darknight in comments could work, But I found the easiest way is to replace steps 8,9,10 of the instructions by the following terminal command:

sudo apt-get install android-tools-adb android-tools-fastboot

and then continuing as normal (and of course write fastboot instead of fastboot.exe in steps 15,16).

That saves the trouble of manually downloading and installing flashboot and configuring files and so.


These happens sometimes. But after 1 or 2 try it will work.
Try these steps.

How to copy 2GB video from Samsung Galaxy Orbit running Android 9 to Windows 10?

Files successfully transferred with SD card.


There are multiple misconceptions in your "workflow", so let me try to explain them one by one:

You've copied the files to your device and placed them into a directory.
Once that was done, Android's MediaScanner found them and added them to its "library"
I've never heard they are added to the Music folder, so that might be something specific here. They were obviously not duplicated (that wouldn't make sense), so what you see as "Music folder" (you didn't specify where you checked that) is most likely rather a "virtual folder" / "Library" / "View".
As the second place was not a copy but rather a pointer, that pointer disappeared as well as soon as you deleted the file.
A "playlist" can be compared to a text-file listing up available music files, it doesn't contain the files themselves. So as you removed the files, their "pointers" were removed here as well.

So much for what has happened. Next point is that Android is not Windows (but rather based on Linux). By default, there is no "recycle bin" (though there are apps available to emulate that). Gone is gone.

For recovery (and recycle bin) you might wish to take a look at:

my listing of De-Deletion (Recovering) apps
questions tagged data-recovery
our data-recovery tag-wiki

I recommend following these links bottom-up ;)

I am unable to run Google assistant on my phone

According to DeviceSpecifications.com, your Lyf Flame 8 (LS-4505) device has only 1GB of RAM and a 480p (480x854) display. It shipped with Lollipop, but further research indicates it was upgraded to Marshmallow.

According to 9to5Google, Google Assistant requires the device have Marshmallow or newer Android, 1.5GB of RAM, and a 720p display. Your device does not meet the minimum requirements to use this feature.

As far as alternatives, a simple Google search will yield a variety of options, I did not investigate them to see if your device meets the requirement for any one specifically (this is not the Software Recommendations site), but you can start here doing your own research.

What is the criteria that Android depends on to join contacts from different accounts?

Raw contacts are joined according to rules described at Using the Contacts API:

  Two raw contacts are considered to be a match if at least one of these
  conditions is met:

  They have matching names.
  Their names consist of the same words but in different order (for example, "Bob Parr" and "Parr, Bob")
  One of them has a common short name for the other (for example, "Bob Parr" and "Robert Parr") One of them has just a first or last name and it matches the other raw contact. This rule is less reliable, so it only applies if the two raw contacts are also sharing some other data like a phone number, an email address or a nickname (for example, Helen ["elastigirl"] = Helen Parr ["elastigirl"])
  At least one of the two raw contacts is missing the name altogether and they are sharing a phone number, an email address or a nickname (for example, Bob Parr> [incredible@android.com] = incredible@android.com).

  When comparing
  names, the system ignores upper/lower case differences (Bob=BOB=bob)
  and diacritical marks (Hélène=Helene). When comparing two phone
  numbers the system ignores special characters such as "*", "#", "(",
  ")", and whitespace. Also if the only difference between two numbers
  is that one has a country code and the other does not, then the system
  considers those to be a match (except for numbers in the Japan country
  code).

  Automatic aggregation is not permanent; any change of a constituent
  raw contact may create a new aggregate or break up an existing one.

There is also explicit aggregation, that can be set for raw contacts, if a user explicitly wants two contacts to be joined. Read more about it in the article.


Why do the buttons on my Incredible occasionally light up?

You phone should light up when you activate it.

When an internal process either stops or wakes up you phone (like you said to start data transfer) or on other actions the lights can light up.

When a process crashes my phone lights up the control keys too, usually with a buzz.


Battery Popup at 25% english with system in spanish. Possible malware?

Settings > battery > advanced settings and turn off the app power monitor.

I haven't seen the pop-up since yesterday morning when I did changed them.


How do I backup my website homescreen shortcuts?

Everything on the home-screen is organized by the configured "launcher" app. Therefore it depends on the used launcher.

Some advanced launchers include a functionality to export the complete launcher configuration including web-links and all the other launcher icons.

The default launcher is usually modified by the manufacturer hence it is difficult to say what it supports.

As a fallback mechanism you can try to create an backup of the launcher via Android Debug Bridge (adb). However this requires to

Enable Developer menu
Activate in the Developer Menu the Android Debug Bridge
Connect your Android smartphone to your PC via an appropriate USB cable
Install the ADB drivers and ADB on your PC
Identify the package name of the used launcher
Perform the backup on the command-line/terminal of your PC via adb backup <packagename of launcher app> launcher-backup.ab.
Check the created file launcher-backup.ab if it is larger than a few kilobytes then the chance if good that the backup was successful

On the new device (or after a factory reset) you have to more or less perform the same steps. Just execute adb restore launcher-backup.ab as the last step.


Why can't I delete pictures I've sent in Google Hangouts in my gallery?

You can delete the photos via the Google+ app or web interface. From the left-hand menu, click Photos. If you haven't turned on auto-upload and don't want to, click Not now to get rid of the prompts. Then, if you're in the app, open the menu that slides in from the left again, and choose Albums from the menu; or in the web interface, click More on the top, then Albums on that menu.

From there you can see the Hangout photos, listed separately from the 'real' photo albums. You can select and delete them to your heart's content. Note that "deleting" a photo from this view doesn't delete it right away: it moves it to the "Trash" or "Bin". To finish them off, you can find that on the same menu you were just on, or just wait for 60 days.


Samsung Galaxy S5 quick message responses limited to 160 characters

A "solution" is to use a different app. It's not ideal but the changeover is smooth enough.

The app I've switched to is called Textra. Use it with the program NiLS to configure notifications on your lock-screen that you can reply to. This program also works with programs like WhatsApp, Snapchat, etc.


I too had a same problem on Xeperia X8. I guess the cause was I kept on downloading the android apps without restarting the mobile for months. After experiencing similar issue like you I have just restarted my mobile, did not revert any settings to default or upgrade OS to latest.

It solved !!.


How to downgrade to Stock Rom [HTC One X 3.20.401.1 CID HTC_203)

This guide is marked as "noob-friendly". Haven't tried it myself as I try to stay far away as I can from Sense:

I had the same problem when I originally rooted on my Droid with Stock ROM.  Eventually a newer version of Froyo came out and I had to upgrade (and lose root) or switch to a custom ROM.  I ended up switching to CyanogenMod.  No more nagging update messages and I kept root.  You might want to consider rooting your phone and switching to a custom rom for the Incredible.


I don't know anything about this phone, but this thread on xda has dump of the stock ROM. I am not sure if it includes the boot.img or not. The dump seems to be android 1.6, the original thread is here and is HUGE.

There is also a 2.2 thread here and it does look like the Zio has its own section on XDA as well. In the Development section, i found this thread. It has the boot.img, but someone posted saying they were unable to use them. I would suggest sending a PM to the person that pulled the boot.img off the device in that thread.

I hope this helps you in some way... I know what it's like to brick a phone, good luck.

Using only your Android:

Kaspersky's Parental Control software does exactly as the title says.

Mind you, it's still in beta, but I did install it and tried it out, and it seems to do it's job of blocking websites as well as applications.

By the way, Kaspersky's not the only app out on the store that you can use, but I chose it due to its reputation. It's after all an application that is going to monitor the network traffic and if it's just any other app, it could steal your credit card numbers maybe. Who knows.

PS: As far as I know, this application cannot be hidden, unless of course you installed a launcher like Smart Launcher. Even then, there is an option for you to show the hidden applications, so it's not going to do much good.

If the phone/tablet is accessing the internet through the Wifi alone:

In this case, you can setup your router settings so that it blocks certain sites etc. It won't be too hard to find the settings; just enter this URL in your browser - 192.168.1.1 - and you should get an interface to login to the router.

For more info, I suggest you did a search on Google on how to block sites through your router.

Advanced Option

I'm not very sure about this method but it should work.

Get a server setup to act as a proxy.
Setup a program on the machine so that it'll be able to monitor and restrict access to a selected number of websites.
Route the phone through the proxy server... and it should do the job.

PS: I welcome comments from anyone who knows if this method is really workable.


How to distinguish Nexus 7 (2012) and Nexus 7 (2013)

There are several physical differences

Most notable is the different orientations of the "Nexus" logo.
The 2013 model drops the dimpled texture on the back.
The 2013 model also has a camera on the back, which the 2012 model lacks.
The 2013 model has a notification LED on the front, which the 2012 model lacks.
The 2013 model has a speaker grille on the top for stereo sound in landscape, while the 2012 model only has the bottom speaker grille.

From @AndrewT 's comment, I gathered this:

Referring this answer on StackOverflow

What does stop do?

stop entered in a root terminal basically stops the Android process called zygote. This in turn stops all processes registered in the context of zygote, that is, all services (including system services) registered to zygote. This includes the SurfaceFlingerprocess responsible for rendering the Android UI.

So, nothing displays on your screen once you enter this command, but the Linux kernel below Android is still going, as you can check if you have a UART connection to the device, or have set it up to specially broadcast output to ADB even if zygote has stopped.

A power-on isn't possible after stop as technically the device isn't powered-off.

What is zygote?

zygote is the hosting process for any Android app. That is, it holds the context of the app and the app itself, and on versions of Android below 5.0, hosts the Dalvik VM instance for the app. It is a system-level process, started on boot.

So how can you recover your device?

Try a hard reboot. That is, pull out your battery, leave the device alone for 15 or so minutes, and then put it back in and boot it up again.

If your device lacks a removable battery, the workaround is to hold down the power button until the device vibrates or shows the bootloader splashscreen. This usually takes about anywhere from 10 seconds to 1 minute.

If you can get the bootloader splashscreen, you are (relatively) safe, you aren't hardbricked. Further steps can be added if Android fails to boot past that step. If that happens, and you have a custom recovery and a NANDroid backup, just restore that.

If you can't get the bootloader splashscreen, check if your device charges when connected to a mains source. If it does, you're still relatively safe and a restore is possible (but out of scope of this answer, as it is very device-specific).

If it doesn't even charge, a recovery may still be possible but you are effectively hardbricked. Maybe the service center can help you further.

Note that the cause of the soft or hardbrick wasn't the stop command, probably something else. What, can't be said without further details.


Why can I not assign exec permissions to a file on the SD card?

Unless you've done something unusual with your device, the SD card will be formatted as a FAT file system, which does not support *nix file permissions. This Linux FAQ entry from one of MIT's professors explains it a bit, and also explains how you can potentially use mount options to change the permission mode of the device (this would require root, though, and affect all files/folders on the device). Also, the SD card in Android is mounted by default with the -noexec flag.

For the exec bit you'd probably want to remount with a umask of 0000, since the umask is essentially a binary NOT of the permissions you want (so umask 0000 says don't mask out any permissions, allow them all). Untested, but doing it temporarily would be something along the lines of:

mount -t vfat -o umask=0000 /dev/your/sdcard/device /mnt/sdcard

The mount point may need to be changed from /mnt/sdcard to something slightly different depending on your device. Again, though, I believe mount requires that you have root permissions for this.


Successfully installed TWRP and Magisk means bootloader unlocked?

Install Google's ADB drivers, connect your phone to your PC, open a command prompt and type:

adb reboot bootloader

Then:

fastboot oem device-info

And you will see the bootloader's status, either in the command prompt or on the device's screen.

To unlock a locked bootloader, type:

fastboot oem unlock

Remember that unlocking the bootloader will wipe all of your user data, as a factory reset does. Backup your data first.

Since you have a Samsung phone, remember that Fastboot isn't supported, while Odin is. To unlock the bootloader, simply find the OEM unlock entry in the device's settings and enable it.


Some questions regarding apps on a rooted Nook Color

A vast majority of it. My device says I have up to 5gb of internal storage that I can use. Additionally you can throw in an SD card.
In my experience about 98% of the apps on the Market will work on your rooted (stock) Nook Color.  If you flash CyanogenMod 7 or similar, then they all should work.  If you remain with stock, there are some minor quirky issues because there are a few things missing from the OS.  For example, trying to create a "shortcut" will cause a Force Close.


How do you securely delete android 6 phone?

Yes, a factory reset of an encrypted device will wipe your device and delete the encryption key; it's a secure wipe (you can see some of the requirements here).  If your SD card is not encrypted you might need to handle that separately — a full (non-quick) zeroing format from a PC should be sufficient if you don't want to reuse or destroy it.

A "hard reset" can either refer to a hard power off and reboot, or to a factory reset; obviously in this context it would be the latter.

My Galaxy S has had a software upgrade and now it only types digits on the 3 x 4 keypad

Go into:

Settings
Language & Keyboard Settings
Samsung Keyboard
Keypad types, tap that

There is various styles , 3x4 keypad is probably selected, the one you need is Qwerty Keyboard.


I'd personally use Tasker for something like this. The process would be quite simple:

New Trigger -> Time
Give a time window (workday 7:00 am to 5:00 pm)
Check "Repeat:" every xx and change to Minutes
New Task -> Name (something like "Open Webpage")
New Action -> Net -> Browse URL
Type in URL

That Task should cause the device to relaunch the webpage every xx minutes through the default browser, so we're assuming that's set to your Kiosk browser.


Is there any way to do automation/repetition based on user input?

Try Repetitouch: https://play.google.com/store/apps/details?id=com.cygery.repetitouch.free

It Allows you to input a set of touches and swipes, and the app will repeat exactly what you have recorded.  You can also set stuff like delays, speed, or amount of repetitions.


Is there a way to control the app and notification volumes at once on a phone like there is on a tablet?

That depends on your Android version and device, but based on what you said it seems like you should be able to. You can try Volume in Settings, or you can download Volume Control and control various different volume levels and settings.

Several attempts to get this are posted here, but it doesn't seem like some devices have it.


You can install a new launcher, such as Google now launcher, if you do not like the new Touchwiz layout.
