How to use Android Device as Wireless Headphones for TV?

I know this app on the Google play: Wireless Headphone
that does exactly what you want. You need a 3.5mm-to-3.5mm audio cable and connect your TV's headphone output to your laptop microphone input. And then you can listen to the audio on your Android phone.


Motorola Moto G (2nd Gen) mobile hotspot not forwarding packets

I faced the very same issue with MOTO E, MOto G2, 3 and Now with 4. everything works fine if i use Bluetooth tethering or USB tethering. as soon as i connect my Laptop with WiFi of the G4 (WiFi threatening option) it connects but shows a yellow mark over Wifi.

I tried every single trick available over Internet but nothing worked. finally i did a small change and everything became fine. what i did is as follows:

click on wifi symbol and go to the available networks--> find the network of your hotspot and right click--> go to connection properties --> change encryption type to "AES" if already selected go to advance setting--> click over check box (enable FIPS compliance)--> click ok --> click OK again and you are good to go.

i tried this on windows 8, things must be more or less same for windows 7 and 10.


Long tap the username field, tap the three dots next to "Paste" and select autofill. There will be an option "Enable autofill for " where you can re-enable it.

Tried on Android P


Factory Reset apparently is the answer.  Came up straight away.  Having to blast the tablet every time you want to use the internet is not convenient.


You have to take it to a repair shop that has an ultrasonic cleaner.
You can't put it in rice or any other ridiculous mythical magical fix.
There is one option for you. ultrasonic cleaner.
Why does rice and those other methods not work?
CLICK HERE FOR CITATION
Water is not harmful to electronics, it's the impurities in the water that hurt the electronics and cause corrosion.
Tell me what rice is going to do? Nothing. Don't use rice. Don't buy kits at the 95cent store. Don't do anything you read online. Don't follow YouTube videos. It's all fake stupid advice that doesn't work and can cause more harm than good.
If you don't have access to a repair shop and you just want to try to fix it yourself you can try to take apart the whole phone. Get to the circuit board and painstakingly clean every single part of the phone with high grade alcohol and a toothbrush. This is not as effective as an ultrasonic cleaner.
Also keep in mind an ultrasonic cleaner is not a guarantee. Water damage is the worst possible thing you could do to your phone. You are 99% screwed. Even if you take it to a repair shop keep in mind they will have NO GUARANTEE for water damage. That means that if they don't feel like cleaning it they don't have to. They can just take your money and do nothing because there is no guarantee with water damage. Even if they clean and fix it afterwards the problem could come back. BE CAREFUL PICKING YOUR REPAIR SHOP. GOOD LUCK!


How are "ShareIt","Xender" etc able to install APK without requiring "unknown source" permission?

I did a bit of digging and it is possible without System permissions from API 21 onwards https://developer.android.com/reference/android/content/pm/PackageInstaller.html.

In fact, there is a code sample by Google which shows how to do it. https://github.com/googlesamples/android-testdpc/blob/master/app/src/main/java/com/afwsamples/testdpc/cosu/CosuUtils.java


Copy YouTube APK from Android Phone to PC

(Comments Reference) Since your main motive is to get the APK file, we can try three approaches here:

1) Using a backup app: There are a lot of great backup apps like Titanium, but since its just as a temporary solution with only motive to get the APK file, I would suggest using a simpler backup app like Android Assisstant. Using this, we first backup Youtube APK and then we copy it to PC.

Open the app after downloading from above link.
Go to Tools->Backup and Restore

In the list, check-mark the YouTube.apkand press Backup.
The app APK would be saved in directory /sdcard/AndroidAssisstant_appbackup which you can transfer to PC normally.

2) Using a Root File Manager: Since we dont need to root for reading system, any root browser would work. For simplicity, I would recommend using Solid Explorer (since ES could be a bit too much for first-time users).

After installing Solid Explorer, open the app and press the Jump button at bottom panel and choose Device->System Root.
Browse over to /system/app and copy over Youtube.apk to sdcard. Transfer this file to PC through whatever methods you prefer.

NOTE: Trial version of solid explorer allows you to only open it once. So an alternative would be Root Browser which has a very similar interface.

3) Using Terminal Emulator: Download/Install Terminal Emulator.

Open the app and use the command cp /system/app/YouTube.apk /sdcard/which should copy the APK file to your sdcard that you can tranfer to PC normally.

Hope this helps.


I guess you could do this using the "Conference Call" trick on android (natively!).

The screenshots below are for vanilla Froyo (Android 2.2) and may vary with your version/dialer app.

During your call (Don't hang up the call), after talking to that person, press the "Menu" button on your android. Press "Add Call" from the menu.

Dial and call the number you wish to "redirect" for him. (on your charge! (which is what you asked for right?) Means you will lose money for this call as if you are calling it)

Now press menu button again when call connects. Press on "merge call".

Finally, Press the menu button again and click on "mute" to make them think you have terminated your call. (you mute yourself but you can hear the conversation between him and the "redirected" call)

Remember, while doing these, you will be charged for 2 calls simultaneously!


I need authorization from Google before downloading Messenger but it wants me to sign into my Google account. I am signed in everywhere

You need to relogin as it may be a play services error. just remove your google account/accounts, reboot your phone, relogin to your account/accounts. if it still fails then look for google play services in

  settings > applications > google play services

and do a clear data. after restarting, relogin your account/s it should work fine.


Android App Downloading But Not Installing

Try following the methods below:

How about you try installing the app by manually downloading it's apk which I believe, shouldn't disappoint you.
You must have "Unknown sources" enabled from Security option in Settings menu in order to be able to install APKs.(Settings>Security>Check the Unknown Sources option).
For example, visit http://www.whatsapp.com/android/ and click on Download apk, when download is finished you shall copy the apk file anywhere in your SD Card or internal memory which you can access, or download the apk right-away in your smartphone. You your favorite file explorer(I use ES File Explorer) and navigate to the apk file location in your smartphone and touch to open it just like you would open any file and you will get an option of installing the app.
Power off your Moto G and reboot to bootloader by pressing Volume up + Volume down + Power button and you will be taken to bootloader, from there you should use volume down to scroll down to Recovery option. Use Volume up or Power button to enter Recovery mode and than wipe cache(do not execute wipe data as it will wipe the internal memory/sdcard) which can take 5-10min if on stock ROM. When done, reboot and post if you face the problem again.


Open command prompt to access folders of a USB connected Android phone

In order to assign a drive letter to a removable device, that device must support UMS (USB Mass Storage) protocol.  Unfortunately most newer Android phones, especially those without a removable SD Card, do not support UMS. Instead, they support MTP (Media Transfer Protocol) and PTP (Picture Transfer Protocol) protocols.  In such devices it's not possible to map storage as a drive in Windows.

See more details on this Superuser.com question.

With that said, on some selected Samsung and Sony Android devices it's possible to enable the UMS mode for external storage only (SD Card).  See this app.

Also, if your goal to simply copy files to and from an Android device via command prompt, ADB will allow you to do so.  This utility is part of Android SDK tools.  You will need USB drivers for your android phone to be installed, USB Debugging activated in Developer Settings on the phone, and authorize the PC to debug the phone (via a prompt on the device.)  After that is done, you will be able to use adb push and adb pull commands to copy files & directories, and various Linux shell commands via adb shell <command> (e.g. adb shell ls /sdcard/) to navigate the directory structure on the phone.


Are there any known rom(s) with full device encryption incorporated?

You mean like WhisperCore? Quoting from it's site:

  By default, WhisperCore encrypts your entire data partition at the device level, and can optionally be enabled for your phone's SD card as well. WhisperCore also includes smudge-resistant screen unlock patterns.

Unfortunately it only currently runs on the Nexus handsets.


Sometimes the phone just needs a quick restart. Try that and if it doesn't work then let me know.


How can I automatically re-connect to a WiFi network?

Your issue is caused by Captive Portal¹ Check kicking in and not permitted through by AFWall+. So if you can live without that auto-detection, you could simply disable it:

# check what the original setting is. Should give "1" for enabled, "0" for disabled
settings get global captive_portal_detection_enabled
# now let's disable it
settings put global captive_portal_detection_enabled 0
# if you want to re-activate it
settings put global captive_portal_detection_enabled 1

Implications:

no more pop-ups when connecting to e.g. a hotel network using Captive Portal. Easy work-around: just open a web browser and navigate to any url, the portal should "capture" you for login
no more x on the WiFi symbol – so you might miss the fact of not reaching any network until you try manually (e.g. by visiting some web page and ending up on the Captive Portal's login page)
automatic re-connect to "known WiFis" should simply work.

I've used that trick myself when having set up AFWall+ in a quite restricting mode, and it worked for me. As you (OP) just confirmed in a comment on the question, it did the trick for you as well – despite the additional complication of a VPN.

See Captive Portal parameters for more details on manipulation.

¹ for those who don't know what a "Captive Portal" is, please see Wikipedia

How Can I get Google Natives apps in Samsung Galaxy S?

Installing from Market is preferrable, but you probably can sideload them if you exhausted all other avenues.

Download the apk: http://forum.samdroid.net/f10/google-updates-3468/

If you have adb, then you can install the apk using adb install.

If you don't have adb, then save those apks to the SD card and use a file manager (e.g. Astro, Estrongs, etc) to install them.

You need to enable non-Market installation: Settings > Applications > Unknown sources


How to stop an ongoing download in HTC desire 500?

You can go to download manager and long press on the entry and delete the file from options menu.
Alternatively you can force airplane mode or switch off net/wi-fi to cancel the download.

In rare cases when its stuck in notification then go and force close the downloads app or clear data for download manager app.


If you are located in the USA, Google Voice with Hangouts app may be what you're looking for.

Your wife doesn't need to change anything, as she can text using her carrier's SMS plan.  You will need to do the following:

Register for a new Google Voice number here using your Google account.
Install the Hangouts app on your phone.
Open the Hangouts app, and sign in with the same Google account you used in step 1.
In Hangouts app go to Settings -> SMS, tap on "SMS Disabled" and enable the Hangouts app to be the default SMS app.  This may be different depending on the Android OS version your phone is running.  Refer to this site for more details for pre-4.4 instructions.
In the same Settings screen ensure the "Send SMS From" option is set to "Smart Reply".

Now if you open Hangouts and tap on your wife's contact, a new Conversation screen will open.  On the bottom, to the left of the text entry area, tap on the green text icon and tap "More".  This will bring up all the options, including "... (via SMS)" and "... (via Google Voice)".  The "(via Google Voice)" is the option you want, as it will use your data plan instead of your carrier's SMS plan.

You're all set - your wife will only need to make sure that she texts you at your newly created Google Voice phone number, and not your cell number.  Other than that, she can continue using her SMS plan, while you will be using the data plan, and avoid SMS charges.

Once again, Google Voice is currently only available in the USA, and does not support sending texts to international numbers.


Yes, you can share your phone's WiFi connection which is connected via any wifi source to more phones, tablets and computers using Bluetooth so other devices can access internet. Here's how to share your Android phone's WiFi connection over Bluetooth.

Here is a clear explanation to share your wifi over Bluetooth.

You can download the APK file with bittorrent to you PC. The other link is not usable if you don't want to register to Google Play. After downloading you transfer it to your phone. Under settings and security you have to enable unknown sources and while tapping on the transferred .APK file, it will be installed.


Some of my apps disappeared after wiping cache and dalvic cache. Why?

As for as i know, when a rom boots up for a first time dalvik goes each and every apks and extract the dex (Android programs are compiled into .dex (Dalvik Executable) files) and put in the cache.So next time when you use your mobile it start faster and improved the performance, so when you wiped dalvik cache, it only clear cache memory. it will not delete application data.

i cannot say exactly one solution for your problem without getting more information, try to reinstall apk, maybe it will solve your problem because data is not deleted.


Android Wifi : How to change network interface used by android

Are you sure dummy is a wifi interface?   Typical wifi interface's name is wlan0.

If you're 100% sure it is right wifi interface, you might also need to change the wlan0 inside the wpa_supplicant.conf file.

If that still fails, run the wpa_supplicant command under strace and try get more info from there.


How do I sideload, i.e. install non-market apps, on at&t phones?

No need to load a custom ROM. You have two paths possible -- You can simply use special software on your PC to sideload apps or you can do some edits to the configuration databases on the phone to bypass the block permanently.

This page covers both methods -- http://samsungcaptivate.wikia.com/wiki/How_to_Sideload


What happened to the pop-up alternatives in Google Android Keyboard?

The workaround I found was to go to Settings->Apps->All->Google Keyboard and tap "Uninstall updates".  This reverted the keyboard app to the initial version of 4.021003 that was installed to my Nexus 5 when it updated to Lollipop.

Apparently the feature I am describing was broken/changed some time between 4.021003 and 4.1.22123. I'm going to report this as a regression and see what they say.


One Plus 1 - Logs out and immediately back in WiFi randomly

I used to get these errors till a few weeks back myself,especially on a friend's wifi hotspot, and strangely enough,same problem was on friends' oneplus 2 and 3, and not even a stutter on other friend's nexus6p/iphone6/moto turbo.

Flashing a new rom helped a lot,currently running Mahdi rom, works pretty great and wifi stutters have reduced significantly(still,not zero, although barely once or twice per hour compared to the old 5-6 times back on stock), so if that's a possibility,go for it!
PS Worked on oneplus 2 and 3 as well, Custom Roms in, wifi disconnections out!


According to AndroidPIT, this error usually occurs when trying to download larger applications. The app downloads, but the error message is displayed, saying the installation was unsuccessful do to an error.

As solution, the mentioned post suggests to head to Settings › All › Google Play Store › Uninstall updates. Once you've done this, try downloading the problem app again.

There's also a Youtube video on this issue.

Another article holds two more approaches:

simply restarting the device can already solve the issue
if not, do the same as described above
if still not, at the place described above clear cache and, if that doesn't help, delete data of the playstore app

More advice might be found by a simple Google search :)


Sync contacts and calendar from Outlook 2010 on my laptop with Android phone, avoid data in cloud?

You can easily turn of Google Sync for any Android phone.  Just go to Account Settings, Sync.  One problem is that whenever you get a new ROM, or Google does an update, these settings get turned back on.  So you need to check periodically.

There are a number of 3rd party sync products, with free trial periods.  Just give them a try.  You can find them online.  The best for security may be DejaOffice which has an encrypted mode to really lock down your data.


Is There *Any* Way To Increase Internal Memory?

Theoretically, of course, you could modify your hardware.  But this is not remotely feasible for 99% of us.

One thing you can do -- if you root -- is to install various apps that will allow you to move more to the SD card.  You could also try a custom ROM that is smaller than the stock ROM.  If rooted you will also be able to uninstall crapware system apps (be careful not to touch the important onces).


What are "Manual Updates" in Google Play Store?

It seams that Apps with updates are shown under "Manual Updates" when the update requires more permission that it's previous versions.

A speculative answer to the difference between "Manual Updates" and just "Updates" would be that "Allow Automatic download of updates" does not applies to "Manual Updates".


How can I find out which bands my phone supports

Phones based on Qualcomm Snapdragon, like the padfone X, have their band settings stored in NVRAM, in a field called rf_bc_config. This will be set in the factory to match the band choices embedded into the hardware (radio components in the RF front-end on the device).

The value can be readout using Qualcomm service tools like QPST or QXDM, but it is not a human readable value, it is a bit-field and the bits are not in the order one might expect.

I do not know the mapping of the bitfield, but have seen people speculating on xda forum.

There are no apps to retrieve this information, because it is kept inside the modem software and never offered up to the application processor. The only information ever offered up to the android processor is the current connected band info.

It is possible to change these values in the NVRAM, and many people have, to try and force extra bands to work on their handset - of course, this is unlikely to result in useful performance on the new band, since the hardware support is not present.


Turn off volume button notification sound in Galaxy S2

I haven't found any way to do this through the software. The only way I've found to disable the sounds is to go to /system/media/audio/ui on your phone and delete files Volume-1.mp3 through Volume-7.mp3 for the volume tones, and Charger_Connection.ogg for the connection tone. Just tested this on my phone and it does indeed work. You may want to back up the files first in case you want to restore them at some point. You may also have to be rooted to be able to remove the files.

Edit: Actually, I'm sure you'll need root, as I had to su in a terminal emulator to be able to do anything in that directory.


Is it possible to get multi-user support on Android with help from the boot manager?

you can use SwitchMe if you have root, which I believe does all you ask


I fixed this by disabling and re enabling the application that was forcing my device in portrait mode.

The application I was using was "Set orientation" V1.1.4 from package com.googlecode.eyesfree.setorientation.


How to flash stock ROM .DZ file on a semi-bricked LG Android phone?

There is currently no way to do this.

Where did you get the .dz file from?

You would have to ask the prividor to provide a .kdz file as well as the .dz file so you can flash with the KDZ Updater program.


Keeping your IP address and using a VPN is the complete opposite of what VPNs are invented for. VPNs make you part of a network through a tunnel connection so that your phone is on the same level as locally connected devices.
This means your IP address will be the one of the VPN. If you don't like this, then you should not use a VPN.
Also check your IP on your laptop. It is probably not the one you used to connect to the VPN.
One possible explanation could also be that your work's VPN transfers your IP address as HTTP_FORWARDED_FOR so the server knows you are using that server as a proxy server. This appears not to be configured in your university's VPN and therefore your IP address is not sent to the destination server, which is totally working by design.


They can flash stock firmware and resell it.

Without knowing the exact build number of the device, your data will not be kept after flashing. (I say this because it is possible to keep sdcard storage on some Samsung devices if you flash exact same build number, but it's a long-shot if you don't have it written down.)

They would have to spend a lot of money for professional equipment/service get your data off of it. To name some potential tools out there: reverse JTAG (privately owned, requires a specialist), government software, even Dr. Fone may be able to recover some pictures here and there, but that depends on how the flash image matches up (small chance).

IMO, there's not much to worry about as far as data. Report your IMEI stolen, then go on ebay and craigslist twice a week and see if you can find it! Search your imei # in titles and descriptions, and message sellers what their imei is, etc. You'll probably find it! Better yet, you may be able to track the loser down!


Problems Connecting Asus Transformer TF101 to Mac OS X 10.92

Sadly I can't give you a solution to your software problem (due to the fact that I haven't used a mac in a while) but I can give some suggestions on how to move forward from your current state (as far as development goes).

There are two situations you might be in, I have possible solutions for both:

Situation 1: You don't need the drivers

-As this article states "If you're developing on Mac OS X, it just works"
Meaning no drivers are needed. But there is still other things to be done (instructions in article)

Situation 2: USB isn't going to work/I don't know what the problem with USB is.

Short Term Solution: package up your app in a .apk and throw that on your device.

Long Term Solution: Look into connecting to your device over your network, from a quick glance this looks to be a good place to start: How can I connect to Android with ADB over TCP?

Let me know how it goes, and if you have any questions.

How to delete dumpstate/logcat on Moto E

You are running an USSD(SIM specific) code. Once you enter the last character of an MMI code(usually a pound or hash(#) symbol) your phones parses the code and open the menu for you automatically.

Dumpstate, logcat files are stored on the /data/log partition that, unless you root the phone, you and none of the apps you install will have access to it.

Dialing *#9900# and selecting Delete dumpstate/logcat clears the logs even if your phone is not rooted and this seems to work only on some Samsung Phones. So that excludes the Motorola phones.
(based on the comments from this blog post)

Note: If you enter the MMI code in the dialer app your phone's MMI parser will automatically open the secret menu after typing the last character of the code. If the MMI parser of you phone doesn't recognize the code, then it will not work in your phone and pressing the dial button after entering the code will run USSD code to your network provider

You can try using adb commands to see if you can get help clearing logcats of you phone. The following command clears/flushes the entire log and exits.

adb logcat -c

http://developer.android.com/tools/help/logcat.html

But before trying all these things you need to see the frequent questions under the insufficient-memory tag and its tag-wiki for what to do when your phone storage is almost full.


Spam in comment section on Google Play - what is more powerfull vote down or flag as spam?

I would say that as a general principle, spam and posts with offensive abuse should always be flagged.

Flagging brings them to the attention of someone who may be able to delete the post and the account of the poster.

Downvoting leaves the possibility that the posts remain visible.  It may take a while for a flag to be acted upon but - no flag - no action.


file sharing between android devices without bluetooth and internet connection

I use ES file explorer.  It lets me access my home network disk drives via WiFi.

To test this, I opened my phone to the DCIM photo area, press/hold one file, "copy to" then navigated UP from the SD card, where it gave me my network connections (which I'd already browsed to with ES File Explorer).

I could then navigate down to a directory and say [OK] and the file went to my NAS

I was able to view it (or transfer it) on another machine just fine.

IF you want to use WiFi directly from android device to android device, then both need to be able to go into "Ad Hoc" mode which means something like "without a central WiFi router".  I doubt that's in the "settings" but there may be something in the app store.  (Sorry I refuse to use that new name Google gave the app store, as I am serious, not playing around).  haha.


How do I export several days or events on my calendar as text?

It seems like by using Google Calendar app, an edit can happen on specific event and multiple event editing is not supported.

Below are the steps mentioned in official page of Android cal. app

Open the Google Calendar app Google Calendar.
Open the event you want to add people to.
Tap Edit Edit.
Tap Invite people.
Type the name or email address of the person you want to invite.
Tap Save.

Of course you can invite multiple guests/people to a specific event, but editing multiple event (to share it) does not seems possible at this time via Google Calendar app.

But if you are using Google calendar on Computer, it seems it is possible to share the whole calendar. You can read the instructions for this on the official page, but below are the basic steps.

Open Google Calendar on a computer.
On the left, find Drop-down menu My Calendars. You may need to click to expand it.
Find the calendar you want to share and click the arrow next to it.
Menu on hover over calendar name
Select Share this Calendar.
Under Share with specific people, add the email address of the person you want to share with.
For Permission Settings, choose an option in the drop-down menu. Learn more about these options below.
Click Add person, if they aren't already added.
Click Save.

If you shared your calendar with an individual email address, they'll see your calendar in their "Other calendars" list. If you shared your calendar with an email group , they'll see the calendar in their "Other calendars" list once they click on the link in the email invitation from Google Calendar.

How to recover Google account without username or Gmail address?

you can go through these links to see if you can get your google account back :

google account recovery - link 1

google account recovery - link 2


Applications restore or install from external sd card

This is due to the fact that by default non google-play applications are blocked by default in Android, as a security measure.
To allow these to be installed go to (this may vary in wording across Android Versions)
Settings > Security > Unknown Sources this allows things to be installed that are not form the known (Google Play Store) source.
You can, in later versions, set only the inital install to process or allow any further ones to install.
In android it is similar to this (slight variety in different versions)

On the Kindle it is slightly different:

Did you try flashing a custom rom again? If not please do. The recovery mode might some how removed your system (my guess). Try flashing some other roms.
Good Luck!


Recover data of app not on Play anymore?

Solved. I found a copy Epistle on the web, and installed it using:

adb install 2388.-Epistle_v1.2.1.apk

Now I can see old data again!

Warning: I was aware of the risk that during installation the app may reinitialize its database. If that had happened, then bad luck. The data was comprised of some notes that, while nice to have, would not have been terrible to lose.


Is the old app uninstalled when it is upgraded?

Not quite, no. When you uninstall a package, it also removes other data to do with that package: for example, the app's own private data, its data on the SD card, your default preferences for that app. It also tells any other interested apps that you've removed the app, via an intent broadcast. Other apps receiving that broadcast might take further action based on that: for example, a launcher (home screen app) would remove desktop shortcuts and widgets from that app, since they won't work any more.

When a package is upgraded (that is, replaced with a new APK file with the same package name and a later version code), the old version is stopped, so that nothing from the app is running any more. The old APK file is removed and the new one replaces it, but the other uninstall actions aren't performed: the private app data and default preferences are kept, and the uninstall broadcast isn't sent. Instead, a different intent is broadcast to tell any interested apps that the package has been updated.

So while the old APK file is removed, the effect of an upgrade is quite different to uninstalling the old package and then installing the new one.

In Google Play the situation can be a bit different if the developer has enabled delta updates (called Smart updates by Google).

In a delta update only the changes between the two versions are downloaded and applied to the existing APK. For example, if you have an app that is 15MB in size, and the developer decides to change the background image, you don't need to download the entire application again, you can just download the delta (difference), which includes the new image. The old APK is then duplicated, the new content is injected to the copy of the old APK, and if successful the old APK is removed. The end result is the updated APK.


Unable to login and load web page in Sony Ericcson W8

I assume your selecting Browser > Menu > Settings > Clear Cache ?

You can also try clearing the full app memory from your home screen (outside the browser):

Choose 'Clear Data' and also 'Clear Cache'.

If all else fails you could also factory reset the phone.


How to turn off the spell checker in Android 4.4.2?

Try going into Settings > Language & Input and configure the Google Keyboard.
In there you can turn off 'Auto-correction'. This should stop it from changing the foreign words to English.

You could also try adding additional dictionaries. This should allow you to enter words from different languages without it detecting them as mis-spelt English words.


Facebook stuck notification "cast device not connected"

Quoted from Lifehacker, referencing Android Police:

If you’re using the Facebook app—and there are plenty of reasons not to—you might have noticed a weird, broken Chromecast notification in your shade recently. Here’s what’s causing it and how to fix it.
As Android Police discovered, this notification is being caused by a bug in the way Facebook handles videos. The app now supports casting videos which is nice, but when you play a video, the notification you see above appears with two buttons that do nothing. The only way to get rid of the notification is to force close the app.
According to the site, this is a bug with version 100.0.0.20.70 of the Facebook app, but the problem is not present in the beta app, version 101.0.0.10.70, which you can download from APK Mirror here. Alternatively, you can download the stripped down Facebook Lite from APK Mirror here. Or, just use the mobile site like we’ve recommended for ages.


Speed of WiFi file transfer from PC to phone

Your phone seems to be a bit older as it runs Android 2.3 - therefore I assume it does not support any faster WLAN connection than 54MBit.

Hence the theoretical maximum would be 54MBit = 6.75 MByte/sec but only if you have just a router and a phone. With your PC in the network each device gets less than that.

Depending on the network protocol used you also lose a lot of speed. SMB/CIFS as used by Windows shares is very ineffective. Better use FTP protocol and suitable client for the best speed.

If that does not improve the performance I would suggest using an sd-card in and sd-card reader directly attached via USB 2.0 to your PC.

Is it possible to assign new function to "left swipe" on MIUI11

If you want to get rid off the news feed and have only google search enter in application google then in the settings of the application ( click on more that is in the bottom right corner then settings ) enter general and turn off discover.
If you want to remove the function of left swipe enter in settings then in the home screen then turn off google discover.
There is no option to change google app from function left swipe.


Stop calendar from asking me if I want to turn on notifications

I found the answer and am posting it here for anyone that's having the same issue. Open the calendar app, go to three dots at the top, select settings, go to set default reminders, set both to none. That should stop the anniying pop up.  I am still looking for a way to rearrange color order.  Apparently they will let you do it with stickers but not with colors.


Where does WhatsApp store Images/Videos when Media Visibility is disabled?

In most devices, I have used WhatsApp creates a folder in internal storage. The folder for media files is /internal storage/WhatsApp/Media. It contains subfolders for images, videos, etc.

I am being stalked with Android device manager

It's a really simple solution: change your Google password. This will lock him out of your Google account.

If he never had access to your Google account and he is tracking you from another Google account you are signed into on the phone, go into settings -> accounts and remove the offending account that gives him access to you phone's location.

If neither of these solutions work, you can disable the Android Device Manager for your device entirely. Go to settings -> security -> Android Device Manager -> Remotely Locate this Device / Allow remote lock and erase. This is a foolproof way of fixing the issue, but will remove your ability to use the Android Device Manager entirely and is a new setting added in Marshmallow, so you may not have it. The first 2 options, however should fix this.

As a side note, the fact that he is still tracking you with this against your will could give you legal grounds for stalking depending on where you live.

  Definitely add something about 2-step and make sure not to hook it up to phone number.

This is definetly something to be added, and I'll start out by explaining what it is since while it is thrown around as commonplace today, not many people really understand what it is. 2 factor authentification adds a second layer to the sign in process that makes it significantly harder to log in if you are not the account's holder. After entering the correct password, the application sends a message to the account holder with a second one time use code to log in. This code prevents others from logging in as you. However, this isn't terribly secure as the usual route of sending the message is with a text which can be easily intercepted. Instead, use Google Authenticator, which stores the second code in your phone. I won't go into the specific of why this is more secure. Just know that it is. It's an app you can download that will guide you through the process of setting it up. The second code will always be inside that app. When you need to sign in to a computer for the first time, it will ask for the second code. Open the app and type in the second code the phone is currently listing. Note that it changes every 20 seconds, so if you don't have enough time to type it in and hit enter, wait for the timer to reset.

Apply manual update on Xoom without an OTG cable

If you live in non-US country, then you can follow a guide for installing the US-based ICS on you Xoom that I've written up on my blog. The basic procedure is:

  Install Android SDK and Motorola USB drivers on your PC
  Download US honeycomb stock ROM from here
  Extract all files from this ZIP file into platform-tools folder under Android SDK
  Boot the device into fastboot mode.
  Then from command prompt (with current directory ‘sdk/platform-tools’) run following commands-

  fastboot oem unlock  (this is red pill, at this point your device warranty voids! welcome to matrix!!)
  fastboot flash boot boot.img
  fastboot flash system system.img
  fastboot flash recovery recovery.img
  fastboot flash userdata userdata.img
  fastboot erase cache

  now reboot the device
  go to settings -> about -> update, this will download subsequent ROM update and will install it, and then reboot
  repeat step-7 until all updates are done (will normally need 4-5 update cycles)

Note that it will void your device warranty


How to turn off all notifications of Android Facebook app?

Current solution is the differential solution which I use because the company has no plans and/or motivation to respect the users privacy.
The company tries to impress users by letting them individually change some features of the app, but does not let the user have complete privacy.
There are several contact requests to the company but they are not fullfilled.

Conclusion: uninstall Android Facebook application.


Moto X (2nd generation) international travel

According to the spec sheets, YES, a Moto X 2014 will work in China at 3G speeds.

China provides access to their GSM network over the 2100MHz (HSPDA, or 3G) and 2500MHZ (LTE) spectrums, shown here. A Motorola Moto X (2nd Gen) purchased in the United States (from either Verizon or AT&T) covers that 2100MHz band for 3G, but doesn't touch the 2500MHz for LTE, as seen here. In fact, the spec sheet shows it should work, to some degree, almost anywhere in the world that provides GSM service.


No, Stagefright doesn't work like that. It's not like computer virus/worm which can spread to other device, but it's an OS vulnerability.

It depends only if your device has been patched or not (e.g. OS update/security update). If it has, then you can be pretty sure that such MMS won't affect your device (for particular Stagefright attack vector. AFAIK, there are multiple, not only one).

For further reading, see Stagefright security issue: what can a regular user do to mitigate the issue without a patch?

Google Apps not responding even after factory reset

In case others have the same problem, I was able to solve mine by reinstalling the Android OS and giving Google access to all permission options which it asks for (e.g. using your location, collecting customary information about you, etc). In principle, the installation process gives you the right to forbid the mentioned options, however, when I did that the first time, the problem remained.

Frankly speaking, I would have liked if Google did not follow every movement of mine (like Big Brother in 1984), but at least now I can use my phone normally. It seems we should reconcile with the fact the our tech tools have permanently occupied our private lives.

Hide contacts from Contacts, but still have them appear when the contact calls

Here is the way I used to do it (make sure all of your contacts are backed up to Google):

Delete all non google contacts.
Add contacts to phone that you don't want to appear.
Delete the contacts from Google that you just added to your phone.
In you contact book:

  Menu Button > Contacts to Display > Google Only

Now your contact book will only show your Google contacts, but your phone contacts will show up if the person calls you. This is a little inconvienent if you like to use both your google and phone contacts for different things.

NOTE: this process can be reversed to get the opposite effect (store main contacts on phone, store contacts of people you don't want to see on Google).

What if a thief disabled Android Device Manager in settings

Law One of Computer Crackers: If I can touch your device, I own your device.
Law Two of Computer Crackers: If you device does not have a password, I definitely own your device.

Okay, so those are not really laws, at least not written ones. I am just stating them to make a point.

Because you have no device security to access it, anyone who gets hold of your phone can do anything they want.

What if the thief is smart enough to turnoff the Android Device Manager first before doing stuff with the mobile?
Does Android require Google account password first before disabling the Device Manager?

Then you are out of luck. You do not need a password to disable/uninstall any application through settings.

Will the Remote Erase work once the device goes online ? (Do they use device Id or IMEI for this)

No, it uses your linked Google account to erase the data.

No sim Card. Location Turned off. No Data/WiFi.

But before any of this, you say there is no sim card (meaning no carrier service available) and no wifi. That alone means that you are not able to do anything with device manager. If the thief were to connect it to the wifi, then you could, unless they have removed your account before connecting to the wifi.

load the scatter file, DESELECT all checkboxes (especially preloader)
switch off device completely
flash boot, system (click Download only, Download, then connect usb-cable)
flash cache, userdata (= factory reset if you wanna be 100% sure)

regarding OTA updater

readback boot.img with SP Flash Tool, patch with Magisk Manager, flash magisk_patched.img into boot, root the device and disable the OTA updater from terminal or adb shell

su
pm disable --user 0 com.adups.fota
pm disable --user 0 com.adups.fota.sysoper
pm disable --user 0 com.fw.upgrade.sysoper

after this, restore the original boot.img (unroot device) and uninstall Magisk Manager

(Note: unlocking bootloader is most likely not required for this old device, SP Flash Tool can flash with locked bootloader. However, be aware unlocking bootloader will perform factory reset)


I was looking for something similar and it is hard to find one that would work for android.

However it is not so expensive to have a really good phone switchboard, you may use a very old computer with phone modem and utilized the land line, for example you can get an almost-for-free, an old PC computer from garage sales or bank or company that is in the process of updating their IT systems, (like a Pentium II or III).

Then install either Windows XP or Linux along-side with a PBX server which you can download for free for both systems. Sure it will take a little bit of time and patience to configure, the end result will be worth it, if done properly.

A switch-board that will change a PC at your office to a desk phone. Even, you can also have a intercom facility as well (where users can call each other without using land line just over your LAN - just PC to PC), even you can join remote branches or offices into one phone system.

Then you can have internal numbers like 1214 or of your own preference and choice, and share the one line over many users, and the most beautiful part is that there's no need to make new wires and getting phone sets!

Search google for 3cx (for windows) or Asterix for Linux.

What's the correct stock ROM for my unlocked Moto E5 Play?

I've figured it out. Besides the carrier-specific ROMs, Motorola has a "retail channel", called RETUS (Retail - US, I believe).

This is not tied to any carrier, and you can match the factory version by comparing with what you get here:

# fastboot getvar ro.build.fingerprint
(bootloader) ro.build.fingerprint[0]: motorola/james/james:8.0.0/OPP27.9
(bootloader) ro.build.fingerprint[1]: 1-121/42:user/release-keys

Combine the two lines, and we have

motorola/james/james:8.0.0/OPP27.91-121/42:user/release-keys


What's the differences between the different processors available in the current lineup of devices?

From my answer on the When will dual core android phones start to become available? question, there's a good comparison of the HummingBird vs SnapDragon processor systems here. Hummingbird is a system made by Qualcomm and used in phones like the Nexus One and HTC Desire, the Snapdragon is made by Samsung and used in devices like the Galaxy S and Galaxy Tab. OMAP is another system chip brand, this one by Texas Instruments and used in phones like the Motorola Droid and the Palm Pre.

All of three of those are "System on a Chip" systems, where the CPU, some memory, and some other processors like the Graphics Procesing Unit, digital signal processors or wireless signal processing unit are all built into the same chip. Building all of this into a single chip instead of having all the individual capabilities spread out across separate chips gives a lot of savings in power usage, size and space used inside a phone.

The CPU inside all of them uses the ARM processor architecture, which is a standard set of instructions and abilities that the CPU follows. As do the iPhone's processors, the iPhone 4's processor is also made by Samsung and is very similar to the SnapDragon processors used in Galaxy S's. Other processor architectures that you may have heard of are the Intel x86 processor architecture, or the AMD64, one of which is probably powering the machine you're reading this at.


Why does heat problems cause purple tint / pink spots on my camera (HTC One)?

The HTC One's camera has bigger pixels than the regular phone cameras ("Ultrapixels"). When you use your camera in low light, it tries to draw more light from the sensor, so the image looks brighter.

The "purple" issue is caused by bad heat insulation of the camera sensor from the rest of the phone, so when you try to take a photo the heat can cause distortion of the data the image processor chip collects from the sensor and converts to digital image (when you open the camera app it puts the screen brightness to max, so even this can cause the phone to heat up). When you use the camera in low light the image chip relies more on the sensor to collect more light, so this might cause only low light pictures to be affected (especially the color black, where the sensor tries to deliver as much light possible and there just isn't one, as it is dark). When you take a photo in normal light (or with flash) there is enough light and the sensor doesn't try to replace the color black with purple.

The damage to the camera sensor caused by heat seems to be permanent and if it's in an early stage it can be fixed by a software update which just calibrates the image chip to ignore the "purple" image data. But, as you stated, this is a hardware issue and if the software update doesn't fix it, the phone should be sent to a repair center for the sensor and the insulator around it to be replaced. As of November - December 2013 the new sensors are made by a different manufacturer and lack the issue.

How do I turn off screen turnoff during call?

The screen off feature in phone apps use the proximity sensor rather than the luminosity sensor. I am saying this because my device doesn't have a luminosity sensor, but the screen turns off as soon as I bring it near my face during a call.
To answer your question: There is no Android system setting for this as far as I know. It is completely up to the phone app whether it will turn off the screen. If the caller app that you are using does not give you an option to keep the screen on, your only option is to try other apps that have this feature.


The battery charging animation is usually a series of images, displayed in the status bar. Assuming that you are talking about them (the images in the status bar), they are animated when an event is broadcast.

Giving some more detail, whenever a charger is connected, an intent is broadcast, which is received by the SystemUI to animate the status bar's battery indicator image. When a charger is disconnected, another intent is broadcast so as to stop the SystemUI from animating the battery indicator images.

All of this is handled by the file BatteryService.java in frameworks/base of the android source.

The other charging animation that you are talking about, is when an image is displayed on the screen when the screen is turned off, but the charger is connected. This is usually known as off-mode charging, which takes over the framebuffer, and draws an image over it, according to two conditions:
1. charger is connected
2. display is turned off

Answering the second part of your question, the former method, BatteryService.java is in userspace, and you can not do much about it; as booting up the phone with only one service, and it showing the charging images. The latter, if exists on your device, would be when your phone is turned off, and connected to a charger, it usually boots up into the recovery, where it is 'checked' at boot time init whether the charger is present/not, and usually, shows the charging images.


You may need to update your device. If you have already updated your device, you may have downloaded a bad update. Unfortunately, this happened to me too. After i downloaded my update, my phone kept on freezing on the facebook market place. Sprint suggested that i just bring my device to the store. Hope this was helpful.


Will it work if I set up a http/ssh/ftp server on my android phone using the cellular mobile network?

That entirely depends on your carrier's setup. For security reasons, several carriers (not all) block the required ports for incoming connections – so though your setup theoretically runs fine, you can't reach your services as the carrier blocks access.

I have not tried it, but in that case it might be possible working around using a VPN (some apps for that purpose can be found in my app list); a VPN should tunnel those requests to your device then. Again: I've not tested this, so it might or might not work.


Why is my internal memory almost full while the files add up to only a few gigabytes?

Devices have different partitions for different purposes. Data storage is bigger because you will need to store your pictures etc. BUT the partition that your device uses for apps is always limited. You might want to move some apps to sd if you are able to.
For example here is the partition table to a Samsung Galaxy S5:

aboot -> /dev/block/mmcblk0p6
apnhlos -> /dev/block/mmcblk0p1
backup -> /dev/block/mmcblk0p18
boot -> /dev/block/mmcblk0p15

Why does my phone charge more quickly at some outlets than at others (with the same charger)

Could be because

Coffee bar may  be using charging stations which may look like regular charging wall outlets but seem to be designed to charge faster (have not been able to get technical view to back that yet and am searching)
Outlet at home is not providing sufficient wattage either in terms of voltage or amperage, may be because of poor electrical earthing


Phone isn't detected via USB but still charges

A USB connector has two pins for 5V and two for the data signal. Seems like the first are still connected while the latter are not.

Have you tried another cable and restarted your PC?
It's also possible that the phone's socket is damaged or has connectiviy problems.
It's soldered onto the phone's logic board. Did you once drop it with the cable inserted?


Do apps that claim to increase SD card performance really work? Strain on card?

Here's the original XDA thread.

Basically, it shows a fairly significant improvement for some devices.  2048 kB might not be the best setting for your particular device, so you might want to experiment.  I'm running it on my device and noticed a minor improvement; it certainly wasn't harmful.  I'm not 100% sure but I would think it would not increase wear.


There IS a way of creating the picture files (which is what you want - a thumbnail is a small version of a picture file), but not the way you want to do it.

(There's no way of "creating a thumbnail" from a list of instructions for an embroidery machine.)

Moto G2 internet connection switch from 3G to 2G network

The default setting provided in the Phone settings menus is

Setting > More > Mobile Networks > Preferred network type > 3G

Screenshot - Preferred Network Type selection(Click to enlarge image)

This is a WCDMA(3G) preferred setting and that means it switches to 2G network if you have a weak 3G signal recepition in your area.

For enabling 3G only mode follow these steps:

Firstly we need to define in which SIM we want to enable 3G. For this go to-

Settings > Dual SIM settings > Mobile Data > choose the desired SIM.

Now,

Open your Phone (Dialler) app.
Enter this code: *#*#4636#*#*
An app known as "Testing" will be launched.
Touch the first option "Phone information". (Don't touch other options)
You will notice a drop-down option above "turn off Radio" button. Tap on it.
Select the third option "WCDMA Only".

You will see that network has changed to 3G mode in the notification bar. If network doesn't change, touch the "Turn off Radio" button. you will see your phone's signal are lost. Now again turn it on by tapping on the same button. Your 3G/HSPA/UMTS must have been enabled now.

Note: If you set WCDMA only mode and if your 3G network is weak, then it will not switch back to 2G network as a fallback and you will eventually lose your connection until you get back the 3G network. So you might face some interruptions while downloading/streaming etc. Instead of entering the code in the phone dialer you can use this tiny app from playstore called Testing

How to switch back to default?

Select ‘WCDMA preferred’ from the above dropdown list and you will go to 2G/3G mode where your phone will connect to best network mode depending on strength.


Error occured while flashing Galaxy Y with JELLYBLAST V3.0.2

This error comes normally for two reason.

You have a corrupted .zip so you should try re-downloading.
You have an unsupported recovery.

According to your ROM's requirements, You must have stock kernal. Most of the time while rooting, we flash a different kernal. So you may have to flash your stock kernal back again.
And also you must have a CWM recovery, as they say.  You can find it here http://techcure.wordpress.com/2012/10/17/how-to-root-and-use-cwm-for-galaxy-y-gt-s5360/

If you have already done these steps, please let me know. I will try to help as much as I can.


Flashing new rom, are old files deleted or hidden?

What happens to existing files when flashing a new ROM very much depends of the location in question:

your SDCard (internal or external) is not touched at all, apart from the fact you're placing the update.zip for flashing there.
your internal storage (/data and /cache) is neither touched by the flashing process itself. But when switching between different ROMs, it's recommended to wipe these two to avoid complications
some other locations are usually wiped and rewritten. This includes for sure /system, and in most cases also /boot

I know of no case where files are "hidden". Either the entire partition is not touched at all, or it is wiped. It might be that on some partitions files are simply overwritten, though I've never heard of such a case either.


Prevent app installation when switching phones

I finally got an answer for this by contacting google, so here goes:

On your old / current phone, open the Play store app
Go to "My Apps"
Select the "ALL" tab
Scroll and click the gray "X" next to the app to prevent its install on the new phone

This does not delete the apps from your Play account; you can install the apps at your convenience via the Play store web interface and purchased apps don't need to be re-purchased.


Can I clear out broken/uninstalled apps that still show up in the app list?

I also had this issue.

Android apps keep crashing with android.database.sqlite.SQLiteDiskIOException

I encountered exactly the same problem as yours on my Galaxy S2 with CM9 earlier this week.

I figured out it might be the problem that the internal USB storage had some error on it.

Unfortunately, formate Dalvik Cache and Cache won't fix the problem.

You can try to mount your phone onto your computer and try to fix the error using some disk check utilities, which I tried but phone freezes after mount as USB.

At last I fix the problem by doing a hard reset. So I suggest you start from trying mount your phone to your computer and do some quick backup first.

If you cannot even copy out your files, it is the problem of internal USB storage with some logical errors.


Can one app read text field(s) of other apps?

A keyboard can do this - that's how a keyboard works, after all. Not only that, but for some scripts, what you describe is the most common way to enter text. For example, in Japanese, one enters む by typing "mu" (the Latin characters representing the same sound).

You can't do it with a normal app without rooting. Anything else would be a big security flaw.


Problems with syncing emails on Galaxy SIII

I think software update has reverted all your settings, follow the steps :

Do Samsung batteries actually charge to 100% capacity?

First, a battery is not like a watter bottle with a clear, definite capacity. It's more like a balloon that you can charge more than it's designed for, but if you overcharge it, it gets damaged. There's a threshold that the battery manufacturer thinks "safe to charge to", and that's what you're presented with.


Battery meter went crazy and now stays at 0%

Wife had a somewhat similar issue. I went into recovery mode and formatted the cache and it solved her problem. To get into recovery mode it is usually Hold volume up + power, let go of power once the phone vibrates but keep holding volume up.


Check to make sure that you have Google backing up your data on the phone you want to sync from. On your old phone, navigate to Settings > Backup & reset > (Google Backup) and ensure that Back up my data is On. Also ensure that your Backup account is the account which you're logging into on your new phone.

After your old phone syncs (which may take some time, but it will let you know when), you should be able to see your phone on your new device as you are setting it up. You may need to factory reset your new phone in order to see the list of Google backup devices.


How do I play Flash websites on my Samsung Galaxy S3?

There's a HowTo at MakeUseOf.Com describing how to install Adobe flash player on JellyBean. Excerpt:

Enable unknown-sources on your device
Grab the .apk for flash player from XDA-Developers and save/copy it to your SDCard
Use a file manager (such as e.g. ES File Explorer File Manager), navigate to the place you've stored the .apk, and tap the file once. This starts the installer.

Once the installation is finished, you should be able to play flash again. However, not every browser might support it. The very same article mentions how to enable flash support in Firefox:

  Open Firefox, tap the menu button and open Settings > Plugins and choose Enabled.

That way you should be able to use it with your favorite websites.


How can I tell Google Play Music to store the audio files on the removable micro SD card (and not on the internal storage)?

If your phone is rooted you can solve this via a shell command:

  mount -o bind [Path to new Location] /mnt/sdcard/Android/data/com.google.Android.music/

(Replace [Path to new Location] with a Folder on your external SD-Card)

It will basically redirect every access to the default folder to the Folder which is specified.

You probably need to do this every time you reboot your Phone, so you may be interested in putting a script which does that into Autostart.

How to mute phone completely but keep watch's notifications vibrate?

There is an option in the Android Wear app to mute your phone when the watch is connected. This will mute your phone (even stop it from vibrating) but your watch will vibrate (for all notifs that would normally vibrate on your phone).

BUT: there has been a bug since forever where the watch suddenly starts buzzing again. It works most of the time though..


On your phone you can install Show Java or Dexplorer to decompile the apk. Usually such media files are kept in assets folder, but can vary on their development practices. On your PC you can use apk tool to decompile the apk and check the source there.


You are mixing up adb and fastboot.

When a device is booted and visible via adb it can't be accessed via fastboot (and the other way around). Fastboot is only active while the bootloader is active.

Hence if your device is visible via adb devices you have to access it via adb.

If you want to switch to fastboot mode have to boot boot to bootloader mode by executing adb reboot bootloader.

Then you can use fastboot.


Do you have adb installed? Added the android rules and etc? I was in the same boat last night kind of, was trying to run a logcat. Google adb for whateverdistro you are using. Once I set up adb/android rules, my phone would show up via lsusb

Also, not sure if it matters, but do you have USB debugging turned on?

I assume since you are trying to build an image, that you know the basics, but have you tried searching/posting on xda as well?


Does Bluetooth drain power when it's not in use?

Yes.
When it is on, but not in use, it continually scans for the device it has been previously paired with.

This allows for it to do things like-- automagically connect to your car when you get in it.

However, the amount of battery drain is still minimal, even if it is continually scanning.


How to erase all contacts from an Android phone?

Replacing a new capacity battery and re-calibration

You can't recalibrate, even if your device is rooted since the battery capacity files are coded in the kernel (see Where are the battery capacity files located?)
Since you don't want to install another app , the only preferred option is to make sure that you are alert and switch off the battery when it reaches 90% (difference of 200 mAh being 10% roughly). Reason for saying preferred option is that while the battery should stop charging when it's fully charged, it appears (to me at least) that the hard coded battery capacity files have a role to play on some cases. This is to avoid possible overheating of battery
This can be inconvenient, so you would need an alarm to alert you that it has reached 90% level. You can do this by automation or by using an app like this, which allows you to set an alarm for custom battery charging level ( I haven't tried that app out, picked randomly from many such apps on Play Store)
You may like to read this Ideal charging / discharging percentage for maximum battery life? and set the alarm lower around 80%, if you are keen on battery longevity. This is a theory that is being debated , so it's your choice


Some Google Apps Accounts Stuck On "Waiting for Sync"

Are you using your main Gmail password, or a 1-time use password.

Check out this link
http://support.google.com/mail/answer/1173270?hl=en


This is a bug in Cyanogen OS 13.1. Go to Settings > Personal > Apps, open the three dots menu and select Show system. Find Google Contacts Sync in the list, select, and tap DISABLE.

I am not sure as of yet whether this breaks any functionality.


For versions above 2.3.6, you could check the Google Developers page for the stock images for the nexus phones. They could provide a context for the sizes of pure Android.

There is another site i had seen comparing all the features of all the versions of Android. I can't seem to remember the name though

Edit: Found the site here.


How would you use your ext4 formatted thumb drive via OTG on Android?

External SD cards and USB OTG drives (since Android 6) are handled by vold which supports only FAT[N] (vfat) and exFAT (since Android 9 provided that OEM adds support to kernel) filesystems on stock Android. ext4 and f2fs are supported only for private volumes (Adoptable Storage). Public volume (secondary external storage) is not directly accessible to apps or readable as emulated filesystem. But it's writable only through Storage Access Framework APIs. For details see How to save files to external SD card?

With root access you can manually mount ext4 filesystem (on USB stick or SD card) with proper permissions (after vold fails) and read/write files there. Use sdcardfs or FUSE to emulate the filesystem for fixed permissions. But this way Android framework is unaware of mounted filesystem and Android apps won't be notified of new storage. Neither you can manage the mounted storage from device Settings.

Going Android-ish way, many custom ROMs include a patched vold which can handle NTFS, ext4 and f2fs filesystems, as well as Linux (0x83) partition type. GUID for that type was added in another patch in order to correctly identify ext4. This patched vold is also available as a Magisk module vold-posix, or you can build yourself from source code to manually add it to /system. Filesystem type might also needed to be changed in fstab if it's not auto (particularly on Android 5 and before).

Another way to access ext4 formatted USB stick on non-rooted devices is through USB host mass storage APIs. While it's theoretically possible and there exist solutions like open-source libaums (for FAT32) and closed-source like Paragon's (for exFAT/NTFS), I don't know of any stable working solution for ext4 at the moment. Related question is: How to read ext4 filesystem without mounting on a non-rooted device?

Google Play Books is available in the US, UK, Canada and Australia. You can find this information on the Google Play help page, and it has also been noted on the @googlebooks Twitter account.


What is the average maximum file size (by default) for incoming email on the Android?

Is this an Android version specific? (ie Gingerbread)

No, this has nothing to do with the Android version, I have several close to me and none have such option. It's probably a carrier-specific setting on the stock app.
bahamat answer easily justifies the reason as to why carriers would prefer such low limitations and how this benefits users.

Is this a configuration one makes when setting up a device with the Android OS regardless of the version? Meaning every device is different?

It may vary depending on the device and carrier, but what usual happens with settings like this is that they are silently applied, but as you've found out, the user can update the value to a more desired one.

How many devices are set with a max file size this low, what's the standard setting out of the box?

There's no standard about the size for an email that goes this low. What actually exists is a general conception regarding the emails maximum size that accounts for the sum of the message's body and the encoded attachment.
Since a message will often pass through several mail transfer agents to reach the recipient, and since most of them have to cache messages for a certain period of time, this brings storage issues that need to be addressed. Since the early days, 10Mb was considered to be more than acceptable for an email.
You can read all about this at Wikipedia.


Problem with unlocking the HTC Wildfire bootloader with HTC unlocker

I think your HBoot needs to be upgraded, and it sounds like perhaps you didn't run the RUU to do so. The HTCdev site notes that phones with an asterisk (*) next to them in the list must run an RUU before unlocking because the bootloader on the device did not originally ship with unlocking capabilities. So first you need to make sure your firmware is up to date (which it sounds like it is), and then you also need to download and run the RUU:

  BEFORE beginning the Unlock Bootloader process your product requires
  that you update the ROM to the version listed in the table below
  first, then download the RUU next to it to enable the unlocking
  capability.

The RUU's filename itself also seems to confirm this. It is listed as PC4910000_Buzz_Froyo_hboot_1.02.0000_R3.exe, indicating (to me, anyway) that you need HBoot v1.02.0000 in order to perform the unlock.


Try flashing the stock firmware with Odin. This should work.
Stock firmware download here
Odin flasher download here

Open Odin
Unzip the firmware zip file
Click on APP and browse to where you extracted the firmware zip file
Boot the phone to Download mode (Volume down + Power button)
Connect the phone and click Start.


Ya one click root apps can have funny side effects like that. since you can root i'd assume your bootloader is unlocked id suggest you use a program called odin on your pc and flash Chain fires auto root https://autoroot.chainfire.eu/
first do a hard reset deleting everything from the device. then flash the appropriate version on your device. i've used chainfire for a long time with no issues.

good luck


You cannot lock the recovery. That's not recovery is intended.

The only chance to do so is locking bootloader.

However, if the bootloader on your device is not locked when it's out-of-the-box, then it can't be locked. Factory Reset Protection won't have much effect in this case.


What happens to my Google Play Music library when I unsubscribe?

What happens when you cancel your subscription from Google support page says (emphasis added)

When the end of the billing period is over and your subscription is canceled, you won't be able to access music you downloaded to your device, or playlists you created.
If you subscribe again, you'll get access to your radio stations and also the playlists and music you uploaded.

What's the purpose of Strobe frequency adjustment in Torch?

Strobe light is a kind of light which goes on and off a given number of times. The inverse of the number of times it goes on and off in a second is called its frequency. Strobe lights are used to see rotating objects to give an illumination that the rotating object is stationary.

By adjusting the strobe frequency the speed of the rotating object is matched to get the desired illusion effect.

There are many uses of strobe light from testing and instrumentation to dancing!


Can I use the default music app in ICS without linking it to my google account?

I'd guess this isn't CM9 specific, but based on a quick test on my Kindle Fire you can just hit the Back button on the account select screen the first time you launch Music and it will simply skip it. Also, you can unlink your account by clearing the Music app's data in your settings (Settings->Applications->Music->Clear Data).


Why alarms in "To-do" applications are shown as notification

Astrid has this functionality. Add a task by giving it a title and then clicking ADD A DUE DATE if you wish. This opens a page where you can tap a due date + time. Click OK after making the necessary changes. Click the blue + sign on the right to add the task to your list.

Now tap the task to edit it - Scroll down if you need to and select DETAILS and then REMIND WHEN DUE & OVERDUE

Choose the options as you see fit and ensure that the RING/VIBRATE TYPE is set to UNTIL I DISMISS ALARM.

Click ADD AN ALARM and choose when you want to be reminded.

To avoid this rigmarole in the future, you can choose to set by default that reminders should ring constantly until you dismiss them. Click SETTINGS > NEW TASK DEFAULTS > DEFAULT RING/VIBRATE and then select UNTIL I DISMISS ALARM

Also see REMINDER SETTINGS where you can choose a ringtone of choice.


What is default "fstab" file in Android?

It can be in / (ramdisk), /odm/etc/ or /vendor/etc/.

Android Storage Configuration:

  For Android releases 4.3 and later, the various fstab files used by init, vold and recovery were unified in the /fstab.<device> file

Next change occured with Treble when vendor/SoC specific code was separated from Generic AOSP code. So fstab was moved to /odm or /vendor.

default_fstab_path reads GetFstabPath():

// Identify path to fstab file. Lookup is based on pattern fstab.<hardware>,
// fstab.<hardware.platform> in folders /odm/etc, /vendor/etc, or /.

Commit states:

  fstab contains device- and soc- specific content that should reside in
  /odm or /vendor partition. This change searches the fstab.${ro.hardware}
  file from /odm/etc, /vendor/etc and /, then use the first one found.

fstab contains entries for all filesystems to be mounted on boot or in recovery from partitions including system, vendor, userdata, cache, misc, persist, modem, dsp etc. See details in Android Partitions and Filesystems.

Some of the entries of fstab are moved to DTB. See "WHERE FSTAB IS?" in How to disable dm-verity on Android?


Is it possible to do DNS resolution based on connection?

DNS resolver always consults local /etc/hosts file before sending DNS query to configured name server (see details in How does Android OS do DNS name resolution?). So this approach cannot work based on connection.

The possible method is to run a DNS server on that specific network and configure DHCP server (mostly your router) to send local DNS server's IP address in response to DHCP requests. Configure DNS server to always resolve a domain name to a fixed IP. Or you may resolve the domain name to required IP using a VPN app temporarily (it's less hassle than editing hosts file every time). See linked answer for details.

This app is actually part of the Google Play services app. Google automatically updates Google Play services on all supported devices via Google Play Store to ensure API consistency across devices and versions, and to deliver fixes and new features in a timely fashion.

It is installed on any Android device running Android 2.2 or higher and is updated every 6 weeks and the updates are pushed silently to all supported devices meaning if you uninstall it then it will be re-installed automatically.

It also allows Google to patch some vulnerabilities in Android without requiring a full O/S update or involving manufacturers/carriers.


Real time events show up with a 4 minute delay

It sounds like your clock is 4 minutes fast.   Check to see if your phone is getting its time from the network (on Gingerbread, it's Settings/Date & Time, not sure about CM 7.2).

If you are getting time from the network, try disabling automatic updates and set the time manually to a source like time.gov or time.is.


"adb devices" gives "no permission" when on charge-only

Thanks to the pointer provided by Firelord, I was able to solve the issue. The solution might look weird, but works perfectly:

As root, edit /data/property/persist.sys.usb.config. The only line in that file should read:

mass_storage,adb

We all know there is no usb-mass-storage anymore with Kitkat (except maybe rare exceptions). Well, maybe that's the reason nothing "pops up" anymore, offering to mount some resource :)

To revert from this, either:

open the notification area while connected via USB, find the "connected as …" notification, and tap it
or: go to Settings › Storage, tap the "overflow menu button" (the "3 stapled dots"), and tap the (only) entry which reads like "USB connection"

Then select either MTP or PTP, and there you are.

References:

This is the content of /data/property/persist.sys.usb.config on one of my tablets running Android 4.1 (stock)
This setting is mentioned in this answer, saying if you want to eanble ADB, you can setprop persist.sys.usb.config=mass_storage,adb

Postscriptum

Thanks to the context, one could set up some "toggle" using tasker, executing either setprop persist.sys.usb.config=mass_storage,adb (to "get rid of the popups"), setprop persist.sys.usb.config=ptp,adb (to have it back in PTP mode), or setprop persist.sys.usb.config=mtp,adb to re-enable MTP for data transfer. I don't need any of this, as I use adbfs to access my files ;)

I did not have any issue making a similar change myself, using the guides online that walk you through switching your Samsung or Telco branded Galaxy Nexus (on the Samsung upgrade track) to a Google branded one on the much faster Google upgrade track.

Don't skip any steps, and be sure to back everything up, and be aware that you are probably voiding your warranty. I linked to a 4.1.1 upgrade guide; I am sure there are newer ones out, though most of the guide will be identical.


you can change the numbers by going into Settings>>Account>>Change Number.

Also you can select an option if you want you contacts to get notification about this change.


Find lost device without Gmail account configured and without SIM card

No, there is no way to track it without having it configured in some way to connect to a wireless source of data.  Without a SIM card you can't do that via a service provider and without having the Google account configured (and thus an authentication token that identifies your phone) you can't do it via WiFi (if you have it turned on).


How to use OTG cables for NEXUS4 without rooting

The Nexus 4 does not support USB-On-The-Go. From the Nexus Media Importer description on Google Play it states that:

Is it feasible to install 3000 mAh battery to MMX A89 mobile?

According to this site, your Micromax A89 Ninja phone has a removable back plate with a replaceable battery.  It should be possible to replace the original 1400 mAh battery with a higher capacity one. However such battery will definitely be thicker in size, so you would most likely need to buy a different back plate to accommodate for the added thickness (see an example for Galaxy S4 here.)

I have not found any online merchant that sells extended batteries for Micromax A89, but you may have better luck with local cell phone dealerships in your part of the world.

How can I make it so that any user can chmod in my fuse-mounted ext4-formatted /sdcard?

Chmod will never be supported. That's on purpose according to comments in the source code.

Here's a reference to the FUSE implementation on Github pointing to a comment that says this.

And the original head on Googlesource (a bit harder to navigate than Github).

Even root cannot bypass it:

shell@android: # id
uid=0(root) gid=0(root)
shell@android: # touch /mnt/sdcard/x; ls -l /data/media/0/x
-rw-rw-r-- media_rw     media_rw        0 2013-01-05 17:35 x
shell@android: # chmod 777 /mnt/sdcard/x; ls -l /data/media/0/x
-rw-rw-r-- media_rw     media_rw        0 2013-01-05 17:35 x
shell@android: # chmod 000 /mnt/sdcard/x; ls -l /data/media/0/x
-rw-rw-r-- media_rw     media_rw        0 2013-01-05 17:35 x

Note that ownership is hardcoded to media_rw:media_rw (below /data/media). PS: /data/media is another story, all the regular permissions apply here, it's ext4 and root is allowed to do whatever it wants.


How can I set Android Galaxy Ace to only use 3G network?

I was in trouble getting my 3G to work, and I did these steps, that solved my problem:

Scroll down, you will see GSM selected;
Open the list and select WCDMA only;
Turn the radio off and turn it on again (there's a button for that on the screen)
Press Home Button, not back button

If you still can't get 3G, reboot your phone and that's it ;)

How to enable silent mode during calendar events?

Llama will let you do this, and it is free (Tasker costs money). It has many of the features as Tasker and Locale, and it can even use Locale plugins. I have grown fond of this app and have set up many automated events.

To do this in Llama, you create two events and two profiles.

Profiles

Create a new profile and name it something like "No Notifications". Uncheck all of the volume options except for Change notification volume. Set the volume level to 0.
Create a second profile and name it "Normal". Again, uncheck all volume options except for Change notification volume. This time, set the volume level to whatever you want, like 5/7.

Events

Create a new event.
Under Actions, click Add Condition and select Calendar Event. Use the defaults.
Next, click Add Action. Select Profile and choose your silent profile.
Create a second event. This one will be the opposite of your first event, so change the condition of the calendar to "Event finished/Not current event" and set the action profile to your normal profile.

The developer of Llama is still working on it and adding new features, and you can get details here.

Samsung S3 i9300 rooted with Heimdall.  Am I able to unroot with ODIN?

You don't "unroot" per se with Odin; you just flash a stock, unrooted ROM that wipes out everything currently on the phone.  It shouldn't matter whether you use Odin or Heimdall.

Note also that unrooting won't matter if you've flashed anything with Odin, since that also voids your warranty and is recorded on the device.


Android tablet disconnects from wifi every ten minutes

Just a stab in the dark, but according to one site, you can try turning off the "disconnect on sleep" option.

How to bypass lock screen in Cyanogenmod 7.2

The answer to this question is hideously complex.  It requires ADB set up on your mobile and PC.  Cyanogenmod enables adb on the device by default.  Instructions for setting adb up on the PC can be found here.

With the phone connected to the PC, using a command prompt go to the directory containing adb, and start a shell.  On my system the command to do this is as follows, but it may be different on yours.

cd "\Program Files (x86)\Android\android-sdk\platform-tools"
adb shell

You will then get a prompt consisting of a single # if all is well.  Enter the following command:

sqlite3 /data/data/com.android.providers.settings/databases/settings.db

The prompt will then change to

sqllite>

Enter the command

select * from secure;

This will produce a list of parameters.  The one you are looking for will be something like:

440|lockscreen_gestures_disable_unlock|1

The number on the left hand side is an <id> which varies from phone to phone.  The next command is then

update secure set value=0 where _id=<id>;

So in this example the command would be

update secure set value=0 where _id=440;

Reboot the phone, and the unlock button will have returned and you will have access to the phone again.


How to recover deleted photo album saved on internal memory - Note 3

Considering you phone is always writing some kind of data to your internal storage, it's going to be a very difficult to recover them - at least not all anyway.

Unless something like PhotoRec can do it (as mentioned in the comments), I'd say they are gone for good.

An alternative, and probably a very expensive one, is to take it to someone who specialises in data recovery. Search for 'mobile phone data recovery' on Google and see what appears in your area. It may mean sending your phone away.

What does it mean to "brick" your phone?

The term "brick" usually refers to the stone, which means: "device can only be used as paper-weight". Taken literally, there's no way to "unbrick".

However, you also find terms like "hard-brick" and "soft-brick" used, which makes the term "brick" less absolute: A soft-brick is something you easily can recover from (count it as a "temporary paper-weight"), mostly by software-based solutions (e.g. re-flash your phone) -- while a "hard-brick" is rather meant in the way the original term points to.

Still, technically spoken, even a "hard-bricked" device could be "unbricked" -- but mostly this is more expensive then getting a new device.

As for the warranty declaration you quoted: For a normal user, it's almost impossible to (hard-) brick his device. Even when flashing a custom ROM, this can rarely happen, as there are many security-layers involved. Almost always you can boot your device into some fall-back mode where it is at least recognized by some "flashing software", so you could simply flash another/the original firmware back. Which means, the risk you are taking is to "soft-brick" your device1. A "hard-brick" is quite unlikely with "normal operations" like rooting or flashing custom ROMs.

Pretty much.

Smart phone batteries last around two years of normal use. Once the 80% capacity is hit, batteries lose their charge quickly.

Even worse, the voltage decreases which causes unexpected shutdowns. Apple tried to solve low voltage with throttling but never informed the customer. Apple is now hit with plan obsolesce lawsuits.

How to keep screen OFF while charging (S3 and Note 2)

I too have not figured out the intermittent screen turn on problem but will address one other issued mentioned.

Lithium ion  batteries have internal circuitry which shuts the charging down when the battery is at 100%. Unless the electronics are bad, you cannot overcharge them. Leaving them discharged for long periods CAN harm them. You can get roughly 300 to 500 recharges, its best to not run it all the way down, recharge often, when not using it, the charges are cumulative, so a 30% discharged battery is best charged then, not when it runs down.

This can easily be verified at manufacturers web sites. Ive learned this from years of being involved in electronics and seeing the evolution of rechargables


How to prevent Android from creating Android and Lost.dir folders on external otg storage?

Android folder is used to keep data about your apps. Deleting it from the internal storage or external storage (when used as adoptable storage) will cause the loss your apps' data.

LOST.DIR is a folder used to place recovered files during boot. It is usually empty. Deleting this folder is safe.

In your case, you can delete both folders without creating any issue. Delete the folders, then disconnect the SD card as mentioned by @Chrisii. It is a process that you will have to accomplish every time because the folders will be re-created by the Android OS when the SD card is connected.
