Meaning of lines in Charging History details view in 4.2.2 Jelly Bean

When the screen is off and no apps are running in the background (e.g. to check email), your device goes into a low-power state called sleep. In this mode, the CPU runs more slowly (or maybe the main CPU is turned off and a smaller, more efficient one takes over) to save power.

The Awake line in the battery chart shows when the device is not asleep: that is, it shows blue when the screen is on or when an app is running in the background. Depending on what kind of background apps you use, you might see brief ticks every 15 minutes or every hour, where the device woke up to perform some scheduled task. If there are long blue segments even when the screen is off, then some buggy app is keeping your device awake. You can investigate which with a tool such as Greenify or Wakelock Detector, and if an app is keeping the device awake, you should report this to the developer.

The GPS on line indicates when the GPS receiver is powered on. This happens whenever an app requests a precise location, and it'll show blue regardless of whether the GPS receiver has calculated a position or not. A brief tick means the GPS was turned on and then turned off as soon as it calculated a position. This is used by Google Play Services' geofencing functionality, by Google Location Sharing, Google Now, and other similar apps that don't track you all the time but want to sample your location occasionally.


benefits of disabling built-in apps on zte z777

On a ZTE Z777 phone, would I gain [usable] app space and storage by disabling built-in apps that I don't use ?

Yes and No. Yes, because if the system app1 has been updated then it would be storing the update (apk) under userdata2 partition (/data), which does consume good amount of space. Disabling such an app would get rid of the update (apk) as well as the user specific data stored under userdata partition. No, because not all the system apps get an update or stores considerable amount of data under userdata. However, if you disable such an app that miniscule amount of data would still be deleted, hence freeing up some space.

  [Some] built-in apps may or may not cause misbehaving of other things. How to know which apps are [okay] to disable?

You don't, although many Google apps (shipped with device) have proven to be safe to be disabled. Consider this rule: if you've a custom recovery installed or ready to sacrifice your data then you can risk going berserk by disabling whatsoever you want (provided that you can, as an ordinary user). Otherwise, play safe i.e. do a web search to reach what system apps have folks found safe to be disabled.

1 System apps are primarily saved inside system partition. You cannot remove them from system partition without root access.
2 All user installed apps, updates to system apps and all apps' data is stored in userdata partition. It is the space here which counts as usable.


Google Account Sync, high battery usage of Google Play Services

My guess is the problem is going to get worse, theoretically, since I an still on 4.2.2, so can't speak with practical experience.

Going by this, Android 6 has a great auto back up system, key changes are:

In addition to app data it saves your settings also
Reinstalling apps comes with data of those apps.
Games saved with 'Saved Games' feature of Google Play Games will have game data restored.
Back up is scheduled to happen every 24 hours or trigger based. This back up mechanism is moved to Google Play services, except for games which are in Google Play Games

The documentation configuring auto back up for apps as quoted in the link states "On devices running Android 6.0 (API level 23-API levels are tied to Android releases, so Android 1.0 was "API 1," Android 1.1 was "API 2," and Android 1.5 was "API 3."  Android 6.0,  is API 23) or higher, the default system behavior is to back up almost all data that an app creates."

I do not know how much has been implemented in the OS and the same article quotes " as of October 10, 2015: of the top 200 third-party, non-game apps, 190 targeted API 22 or lower and thus won't work on the new backup system."
How rapidly this situation will change is anybody's guess but eventually non-game apps I suppose will want to be compatible

So, my guess is that sync is going to carry a far heavier payload than before and surely be a bigger battery hog and also hurt those on data plan.

Bottom line is that it is better to disable sync or selectively sync in Google Play services and Google games services if you want to limit your battery drain, besides uninstalling those Google apps which you don't use. Since the third party app back up with data may take a long time to be fully implemented by app developers, creating custom recovery images as back up would still be required.


Unable to sideload a file to One Plus One. What are my alternatives?

You can flash the phone in fastboot mode.

First you need to unlock the bootloader (if it wasn't done before):

Power off your phone then boot into fastboot mode with power button + volume up button.
Connect your phone to your PC via usb cable.
Open a command prompt
Check your fastboot connection by issuing this command: fastboot devices
It should return your device serial number, if not you need to make sure your drivers are installed correctly.
Once you've confirmed your fastboot connection issue this command:

fastboot oem unlock

The device will now go through the automated unlocking process, just let it do its things.

Done

Flashing thee Cyanogen OS Fastboot Images

Download the latest stock images
Reboot your device into Fastboot Mode (power + volume up) and connect your phone to your PC via usb cable.
Unzip the file you downloaded and put its contents into your fastboot folder.
Open a command prompt.
Issue these fastboot commands (Every line ends by hitting enter):

fastboot flash modem NON-HLOS.bin

fastboot flash sbl1 sbl1.mbn

fastboot flash dbi sdi.mbn

fastboot flash aboot emmc_appsboot.mbn

fastboot flash rpm rpm.mbn

fastboot flash tz tz.mbn

fastboot flash LOGO logo.bin

fastboot flash oppostanvbk static_nvbk.bin

fastboot flash boot boot.img

fastboot flash cache cache.img

fastboot flash recovery recovery.img

fastboot flash system system.img

fastboot flash userdata userdata_64G.img

or

fastboot flash userdata userdata.img

(if you have the 16gb model)

Reboot your device with this command:

fastboot reboot
Done.

Let me know if something goea wrong.


Force all emails to display only the text/plain part

On my device (Samsung Galaxy S3 with Jelly Bean 4.1) I could change this by setting the "Size to retrieve emails" to the minimum (2kb here) on the account settings in the email app.


Wi-Fi connected but there is no internet access

You can try changing your wifi network settings from DHCP to Static and a little tweaking of DNS server addresses should work. refer this link for complete solution.

Under advance settings Change IP Settings from DHCP to Static

IP Address : Most probably your Gateway address will be 192.168.1.1 change your IP Address my changing last digit in this address use any value preferably between 2 to 20.

Change DNS1 to 8.8.8.8

Change DNS2 to 8.8.4.4


I'm using Android 2.1 and the latest official Facebook App.

I go to the gallery and long-press on an image. In the menu, select SHARE and in the list of apps displayed choose FACEBOOK.

I immediately am taken to a text field where I can type in a caption.

by default the images are sent to the MOBILE UPLOADS folder/album, but you can create a new album and specify that as your desired upload location.


How to use Tasker and call an activity within an app called WiWo?

I seem to be a bit late to the party, but here is my implementation for it.

I'm having trouble getting into safe mode trouble on galaxy ace

Well, what you can try is firstly make sure that you have switched your device completely off, next step would be turning the phone back on, pressing power button+and also hold the menu button, now continue holding the menu button until you see the Home Screen ! This will boot you onto the safe mode ! :)


How to create a hardware shortcuts in Android 4.3?

From the description, it seems like Button Savior Non Root can do this (and Button Savior (Root) even more). I didn't try it, and the description is slightly unclear whether it only emulates hardware keys using a floating menu, or you can re-map hardware keys; so your feedback is welcome if you try it.

Alternatively, the XDA developers offer an app called ButtonRemapper. While this explicitly states Tool to remap the hardware buttons, it requires root.

Last partly alternative I can name is tasker. Here I know for sure you can remap at least the camera button. Not sure about others.


How can I save all contacts into google account?

If you want to "sync on demand only": Just enable sync at the time of demand for, say, 10 minutes while connected to your local Wifi -- and then disable it again. Enough time for the service to get its job done. You can do so in "Accounts & Sync"1, after chosing your Google account:

If next to "Sync contacts" you see the same circular symbol as the screenshot2 shows next to Sync Google Reader, you probably do not even need to activate the permanent sync, but simply hit it for a one-time "sync on demand".


missing 3gb of internal storage on samsung galaxy grand 2

Files like downloads are included in misc. Try to click on misc the to view them. The misc items can also be seen from any file explorer. In the second image attached, the total storage is more than 5.17 gib. If you add the values visible, the total is 5.78 gib. From what I have seen, there is no missing storage.


Load the kernel .zip file into the PDA field of Odin, and (if you have it, should have come with Odin) load the 512 .pit file into the PIT field of Odin.  Then flash it just like you did for the Froyo ROM.

A stock ROM is just a ROM that's not modified by anyone, it came straight from Samsung.  If you aren't using a lagfix already, you probably don't need a stock ROM however.  You should be able to find one easily enough in the XDA subforum for your device, if you want it; use JS5, since that's what the kernel is based on.

Your paid apps are recorded in your Google account.  You will never lose your purchase rights to them (barring any service suspensions and that sort of thing).  You can, however, use something like Titanium backup to back them up (requires root).  You can back up the entire device using ClockworkMod / Nandroid; look for ROM Manager in the Market (requires root).

One question: Why are you using that over straight Voodoo?  Voodoo's perfect, and I believe Supercurio has taken stock kernels and added only Voodoo so you don't get any other random stuff.


Screen going black when I press dial button in Lenovo P770 Android 4.1.1

Check this Call settings-> Auto screen off/on during calls

or just clean the proximity sensor with cloth


I use AVG antivirus security which has an option to limit the used mobile data(not wifi data).
I fill information about data pack i.e amount and validity then give the option when to turn the mobile data off (as used in my case it is 90%)
then it ask if I want to further use the data..

Hope it helps you..


The size of more than a gigabyte is true. I also flashed the official ROM of this device a short while ago. As already explained, this is caused in the difference between the very light CyanogenMod Rom (about i think 60 apps preinstalled) and the heavy, overloaded Samsung Touchwiz Rom (about 300 apps preinstalled).

For official samsung roms / firmwares i recommend the site SamMobile.com. They have all of the official roms for all samsung devices and are very reliable. The only negative point is that you have to sign up to download files and even then you have incredibly slow download speeds. You only get high speeds with paid subscription. But there is a "workaround" there:

An XDA user developed a brilliant tool called SamFirm Downloader. With this tool you don´t even need to sign up to SamMobile. You just need to enter the information of your device and ROM and the tool downloads this ROM with full (possible) speed from the SamMobile servers. You can get the tool here (download link under attachments of first post).

Step-by-step:

Download the newest version of SamFirm Downloader in this XDA post and unzip it.
Run the program
The only required information are model and region.
Fill in the model field. Model in your case is "GT-i9506". If you have a different phone you can google for the device model number or look on the sticker under phone battery.
Fill in the region field. This field decides which rom version (vendor) you get, as every single vendor like T-Mobile has its own firmware version. You need to enter the vendor code. You can find it for your specific country and vendor on this site. Just click at the Select country drop down menu, search your provider and copy or remember the short (3 letters) at the end of the line. Don´t download directly from this site as it´s very slow.
The checkbox needs to stay on Auto
Click on Check Update. If your model and region code were correct, it should have retrieved the correct (newest) firmware for your device.
If you want to get the ROM checked for download errors after download completed, check Check CRC32.
Check Decrypt automatically. You actually could do it manually after download, but why don´t let the program do it automatically?
Leave the rest as is and finally click on Download

You´re done! After some time you have the final zip-archive in the folder of SamFirm-Downloader which you need to unzip and then you can flash it with Odin.


Adding web shortcuts with icons similar to chrome's new tab thumbnails

Can't see how to get an individual bookmark with a thumbnail screenshot of the webpage, but there are a couple of similar things you can do with the default browser in ICS.

In the screenshot above the top row are bookmarks added to the home screen by going into the browser, opening the bookmarks list, long pressing on a bookmark and selecting "Add to Home Screen". These appear to be the using the site's "Favicon".

The next two rows are the "3x2 Bookmarks" widget, that just lists the contents of my browser's bookmarks folder. Add that by opening your apps list, selecting the Widgets tab at the top and then long pressing to drag the "3x2 Bookmarks" widget to a home screen. It then gives you a chance to pick a folder in your Bookmarks to show (you could create a new folder in bookmarks beforehand and fill that folder with only web pages that you want to show on your home screen).


Starting emulator for AVD 'Android_2.2' PANIC: Could not open: Android_2.2

Are you starting Android Virtual machine from within eclipse or directly ?

If you are running it from eclipse then before starting eclipse just make sure to run the below command:

sudo export UBUNTU_MENUPROXY=0

Now start the eclipse and try running AVD from it.
I hope this helps. It solved this issue at my end when I faced the similar problem.


Found it. Stupidly, you have to pull down, then scroll through the entire stack of notifications. "Select Keyboard" is buried at the bottom!


Can't sync or even access contacts of Moto G4 / E4 and fresh Android 7.1.1

As I was suggested (in some other source), factory-reseting the phone might do the trick. And it did, but source of problem was different and factory-reset only revealed it.

It turned out that for some reason the Calendar Storage application was disabled on both phones:

It is a system application, so you must tap on ⚙ > Apps > ⋮ > Show system in order to see this item.

After enabling back of this application everything started working with a snap of finger, without even a need of restarting the phone.

I figured this out after factory-reseting of the first phone mentioned in question, so I managed to fix the problem on the other one without need of factory-reseting it as well.

YouTube Premium: Downloaded videos - Original channel deleted?

From Google Support - Delete your channel, which addresses this from content creator view

  Closing your YouTube channel will permanently delete your content, including videos, comments, messages, playlists, and history.

Also here, support says

  ...  If you delete a video, it's permanently deleted — you can't recover it through YouTube.

(Emphasis added)

So, the videos are lost. Even if you download them for off-line viewing, you will not be able to play them because they aren't available any more. For more details on off-line viewing see this answer. It's an old answer but still valid because I see many videos which I bookmarked or downloaded go missing because of channels removed / videos being deleted because of ownership disputes (private videos) in addition to YouTube updates.

Your best bet may be to reach out the content creator and explain the situation to them and explore if it is possible that they upload to a private cloud and give you access (provided this arrangement doesn't run foul of YouTube copyright)


This field is intended to display the owner informations: name, phone or email on the lock screen. Perfect if you have lost or misplaced your device. So I would think that you entered those random letters by mistake.

To enable, disable or change, this go to Settings – My device (or **Sound and display section and then tap Lock screen) – Lock screen – Lock screen widgets.** Then at the bottom press Owner information. Here you can enter any information you want, such as your name or email address.

As a note, if your owner info length is more than 33 characters then your owner info will be displayed as a running text on lock screen.


Photos not sending when attched to a sms on a UMI Touch mobie

Delete some old messages to make some room. You've reached the limits for allocated space for messages. That's stupid, the phone should say: " memory full, please delete some of  your old messages and you'll be able to send new ones"


How can I encrypt my external SD card on Android?

Use BoxCryptor. It has companion applications for Windows, Mac, iPhone & iOS. You can keep your encrypted files in cloud (Dropbox, Google Drive or Microsoft SkyDrive) & access them on any platform.

I use it on regular basis for offline files too (what you are looking for). I keep encrypted container of BoxCryptor in my Dropbox and use FolderSync two-way sync to take all files offline on SD Card. Then, I use BoxCryptor to decrypt those files locally whenever I want.

If you don't want to use cloud, just don't use it. Choose SD card in BoxCryptor app. After inserting the SD card to PC or Mac, one needs BoxCryptor applications of Windows, Mac (Encrypted files are compatible with EncFS-Linux too) & password to read those files & folders (file names & folder names are also encrypted).


My phone is sending out mms messages to unknown numbers

I sounds like you have managed to install some malware - check the Application settings for those with permission to send MMS messages and disable MMS functions for any that you don't recognise or need to be able to send messages and possibly uninstall them. It is probably worth doing this periodically anyway.

If you go to Applications in the Settings area, (the gear), and select the options, (the pile of 3 dots on the top right on my version), you can select SMS to get a list of all the Apps that can send SMS, and presumably MMS.


Does the Kindle Fire original have a camera?

Are you sure that this is camera? It is more likely a light/proximity sensor...


Based on my experience, GPS always loses its accuracy after a few days. Its data becomes stale.

What I would normally do is:

Use FasterFix to make sure I am connecting to the NTP servers nearest me. Refer to this XDA list for suggested NTP servers. You can also use FasterGPS if you like; I have no issues with either apps.
Use wireless networks (Wi-Fi or mobile network) to help fix my location. In my Samsung Galaxy S4, this is in: System settings > More > Location services > Use wireless networks.
Reset GPS data with GPS Test Plus (or its FREE version). When you do this, make sure you are outside the building, where are are no obstructions (trees, etc).
After some time, I check Google Maps and see if my position has updated.

More often than not, this will improve the accuracy of my GPS location. When I notice that my position is off, I check those items I listed above. Also, when you are inside buildings, do not expect to get an accurate reading, unless your phone has a really awesome (i.e. POWERFUL) GPS.


You are asking something impossible here (at least at my knowledge).

If you disable Read receipt or  Last seen, you won't be able to see other Receipt or Last seen.

Staying incognito while being able to see other activities is not possible using WhatsApp. You'll need a clone WhatsApp to be able to do that, may be.


Google Photos deletes copy and original on device

After a while of trying around, I found a solution.
This behavior of the Google Photos app seems to be intended, because it is more an interface for the network service to synchronize images, and less of a gallery app. It keeps track of exact copies and synchronizes them as one. Therefore they are deleted as one instance, even though they are stored multiple times on the device.
Nevertheless, there is a (rather hidden) function implemented that does exactly what I wanted instead.
Instead of using the trash icon...

                            Screenshot of a device folder opened with Google Photos. Trash icon highlighted.
... under the available options, when an image is selected, there is a "Delete from device" option doing the trick:

        Screenshot of a device folder opened with Google Photos. Option menu open. "Delete from device" highlighted.
Note: With this method the image remains in the cloud even if it's removed from all synced folders.
I hope I could help someone who has encountered the same problem.


What is the FastBoot? and what is the difference to obtain the root on Nexus devices?

When talking about gaining root for a given device, it usually means obtaining it for the first time by developers. There are generally two ways of doing this. You can either find a software vulnerability that can be exploited to elevate permissions and sneak in the su (superuser) binary into write-protected system area, or you can flash an image of the device with root already in place. Needless to say, exploiting vulnerabilities is a lot more difficult. This is where fastboot comes in.

On some devices (mostly HTC and Motorola) Fastboot is a special start-up mode that allows you to flash pre-made images onto various internal memory partitions. It is similar to Samsung's "Download" mode, except instead of proprietary software like Kies or Odin (and Heimdall), it uses the fastboot utility that comes standard with Android SDK.

However, flashing can be, and usually is, restricted by device manufacturers to only images signed by the manufacturer themselves (or the carriers). This is what is referred to as bootloader locking. Most new phones ship with locked bootloaders, which makes it impossible to flash custom ROMs. You are back to having to root via the other, more difficult method.

Nexus devices come with unlockable bootloaders, so that you can flash ROMs easily and without restrictions.  Unlocking a bootloader of a Nexus device is very easy as well.  A pre-rooted image usually surfaces very quickly for these devices after they are released.

It is worth noting that with Android 4.3 (Jelly Bean) and even more so with 4.4 (KitKat) Google has changed some low level OS security policies, which renders old rooting methods obsolete. Unlocking the bootloader and flashing a modified image of the OS that circumvents these new policies will soon become the only way to really achieve root.  You can read more about this here.


No OK button in recovery mode on MyPhone Agua Rio Fun

I also have the same kind of phone (MP Rio Fun) and I am trying to partition my SD. In the Recovery mode, you have to use the volume keys/button to highlight the option that you want then you have to press the Option key (the key on the left side of the Home key) to enter the highlighted option.
Hope this help.


To record an online status, the WhatsApp client (the app in device) pings the server once a few seconds (maybe once 10 seconds or something, IDK) to mark that it's alive and connected. If the server doesn't receive a message from the client within that keep-alive timeout, the client will be marked offline..

The timeout (or frequency of sending alive packet) is kept large like this because to avoid flooding the server with pings. Also, it takes time for the offline status to be recorded in the database.. Hence the delay. This is not a bug, this is just how it works..


Gallery opens itself on ZenPad10 while the screen is off

After fiddling with some options earlier, I actually came accross the answer on accident. This is from a feature called ZenMotion, something ASUS started implementing in their Zen phones and tablets, I believe.

Note that not only this answered my question, it also showed me that there were 5 other shortcuts available, with each letter being able to be linked to a different app if I chose so.


Uninstall SetCPU and AdFree if you don't want to use them.  Beyond that, you should do a factory reset to erase your data and apps -- if the ROM/OS is vanilla, then that should be the only thing different from how your phone came in the box.


You might want to take a look at Autowipe for that:

Use Autowipe to automatically and PERMANENTLY WIPE your internal and external data by doing a factory reset. Enterprise and business users should find this useful! This is meant to be used in case your device gets stolen, misplaced, or lost.
Automatically wipes for: failed passwords to unlock screen, SMS password received, subscriber ID changed (SIM card). Use the new integrated test mode to test all these cases. Locks the screen while wiping.

The app does not require root, according to its Playstore description.

Download Contacts backup excel and email and run the app. It will backup all your contacts along with all their info stored I.E:addresses, emails, Google+ profiles. It won't however backup WhatsApp profile data. This is because that data is not contact data but rather data that belongs to the WhatsApp application.


How to play/record sound from Debian chroot?

I managed to make it sound by writing to /dev/msm_pcm_out:

mplayer something.mp3 -ao pcm:file=/dev/msm_pcm_out

Sound is choppy and it looks hacky in general.

Video output is something like -vo fbdev:/dev/graphics/fb0.


HTC Sensation won't boot but vibrates regularly

1-2 weeks later, I wanted to rescue my data, but again it went into the vibration loop. I replaced the back cover with the one from the other broken device I mentioned above and this helped. Once it booted with the replacement back cover, I tried to reproduce the problem with the original back cover but now it boots ok with that, too.
Anyway, the conclusion is that the phone isn't completely lost when this vibration loop occurs.


This page from HTC's website should help you. This might depend on your location and carrier. So please go through the site.

Another option, if you are ready to void your warranty, you can go for a custom ROM like CyanogenMod.


To download the update, I have to reboot my phone a few times.

To install the update however, I will need to unroot (to get the stock recovery), install the update (after downloading it you get the option to install) and then re-root my phone (not necessary but if you're like me, you will want to).


Is there a way to disable notification for whatsapp except from specific people?

The only way to achieve it is the following:

Open WhatsApp
On the main screen, long-press to select a contact
After the first contact is selected, tap on all the contacts you don't want to receive notifications from. You will have to select the contacts one by one because there is no "Select all contacts" button (if there are hundreds or thousands, then good luck selecting them)
Press the muted speaker icon. A pop-up will appear asking for how long the contacts should be muted. Select the time (don't enable "Show notifications" just in case).

The selected contacts will be muted, their notifications won't be shown except only those that were not selected. Note that if a muted contact calls, you will still receive the notification.


Gmail only reads my emails when I press the 'refresh' button - is this normal

Should Android kernel version date match the release date?

To create the kernel for your phone, Sony downloaded Linux 3.18.35 (released June 2016), modified it to include your device’s drivers and built¹ it on the 15th of September. The date you are seeing in version information is the build date, not the release date, of your device’s kernel.
The plus means changes to the code of the kernel were made without being committed to the git² version control system. (read this answer for more info)
Lastly, BuildUser@BuildHost means that the kernel was compiled by a user called BuildUser on a machine called BuildHost.

¹ Or compiled, which means converting from human-readable C code to processor-runnable machine code
² A version control system. After editing code, you commit it to your local git repository to make a record of the changes you made. Then you sync it to the central git repository so your team members receive the changes you made.


Find out if remote wipe has worked (Google find my device)

If it connected after you had the command prepared for it, it would continue to wipe the phone until all user data and apps were deleted once it synced, the only thing that can stop it after it starts is a force restart in which I believe it would continue trying once turned on again.

Once the phone is wiped there is no user data left including any login credentials, there is no way to know if it was successfully wiped and no way you can track it by yourself using google or any other online tracking solutions. If you still have the SIM active you should contact your provider and they might be able to track the phone with your SIM.


Switch to a new Gmail email address without losing account data?

Your email is the key identity for Google account and you are right about starting all over again, if you delete it. See what happens to my google acct if I delete the gmail service?
If your concern is only to have a respectable mail address for correspondence you can use an email alias,for which you can't use Gmail app but alternative explained here Sending email from an alias using Gmail app


Remove a package (upday) from stock theme

Sorry, really a stupid question!

Actually the problem was that I could not find the correct package name for Upday. After a lot of google digging I've been able to discover the mistery.

The package is de.axelspringer.yana.zeropage (so where is "upday").

a normal find / -iname '*axelspringer*' (followed by rm ...) did the trick.


How to get back colored app headers in recent apps list on Samsung devices running on Android Oreo?

It looks to me that this is not possible, because Oreo re-used the color coding for different purpose:

white header: standard app

and here, the original coloring concept is partially present in text color (instead of bg color)

light cyan header: app pair on split screen

I think that this new coloring purpose implies that the original coloring is gone.


How do I auto sync files between my Android device and Windows PC over USB?

MyPhoneExplorer Look Like It solves your problem it's compatible with syncing over USB and best of all it's now ad free.
http://www.fjsoft.at/en/


Not free, but you probably can use Taskerto do this.   I use Pocket Casts to listen to podcasts, and have a Tasker profile set up:

3 Contexts: Shake left-right; app Pocket Cast running; Not Docked Car

2 Tasks: Notify (turn LED on, title "Sleep"); Wait 12 minutes, then Pause Simulate Media Button, then Notify Cancel title "Sleep"

Net effect is that I can shake the phone left then right, and Pocket Cast will behave as if the Pause button on a headset were pushed 12 minutes later.   I used the notification LED so I could tell whether Sleep had been activated when the screen is off.

I'm guessing Pandora would observe the headphone pause function; if it does, this profile should work for you.


Try to install Clockworkmod Recovery, always getting stock recovery

It looks like the key was holding down volume-down, power, and camera buttons until the capacitive buttons (home, search, etc) lit up, which was longer than until the screen flashed (as stated in the CyanogenMod wiki).


Can I have a folder (on the home screen) with more than the default amount allowed per folder on the Nexus 5, which is 16?

While there are root apps/extensions such as Xposed GEL Settings that will let you modify all sorts of settings in the Google Now Launcher (formerly Google Experience Launcher), folder capacity limits is not one of them. Google's aware that this bothers people and it's a confirmed change in Android M. As the Google Now Launcher is installed and updated via the Play Store, it's not impossible that we may see this update reach Lollipop as well, but if so, we have no way of knowing when.

Your only option, which I know you're not interested in, is a third-party launcher.


Encryption and Screen Lock without SIM card

The screen lock is set in Settings -> Screen Lock. The device can then be encrypted without  SIM card.


If the test is not displaying any red this is your LCD (all colors are created using 3 LED (light emitting Diodes) Red Green Blue (RGB)  Sadly your R is DEAD.  It might be something as simple as a loose correction which a technician with a test kit and some soldering could fix.

But I doubt you could do it yourself sorry to say.  Find a good computer repair shop near you.... Or contact Samsung and find an "authorized" repair shop if you are wonder warranty.

Good LUCK!


Need to narrow it down a bit, potentially three items assuming that your phone network operator is not at fault
Phone itself
Data cable
The PC
Can you if possible try your phone and cable on a different PC.
Do you have any data transfer issues with the phone on the PC ? such as backups etc,  worth trying another cable if possible.
Daft one but try the cable in a different USB port too.
Finally if you are able to try a different phone on your PC to test if tethering works.
It may not matter but others could need to know what OS your PC is running.


Repartitioning Internal Memory of Android Device

You can repartition the internal memory. In essence it can be done, but what many others have answered is basically correct. Not only is it quite difficult and risky to perform it, it also requires specialized skills which the average user may not have. There is one solution to the problem though.

The easiest way to do this is to look for a custom ROM for your phone. Many custom ROM providers recognize the issue already and have a fix for it in some way or the other.

Your phone model can provide more information if you like.

How to Remote Control Android smartphone, if not in same subnet

If your phone is rooted (which I'm assuming it is since you're running Oxygen), you could try androidscreencast. It allows you to interact with a rooted phone over USB using mouse and keyboard. It's not the fastest solution, but then again, neither is a VNC server and the like.

There's a fairly decent walkthrough on how to set everything up on How-To Geek. You'll also need to have adb in order to use androidscreencast (the Android SDK is one way; there's probably also some places you can directly download the necessary binaries).


I suggest you get a new battery. Leaving a phone unused for a while drains the battery completely.
Replacing it might be the only solution here.

Good luck!


The shown free space is without the size of the whole Android system. Your internal storage has a total amount of 4GB (Sometimes there is less because the manufacturer defines 1GB as 1 billion bytes). And the Android System and preinstalled apps are also using space.


Android updates availability in different countries

Well, software updates depend on different things:

the manufacturer (if they actually release any updates)
the carrier (unless you get the international version)
your internet connection (no internet = no updates)

You get the updates from the country where you bought the device from (unless you flash a different one, check on the CSC: Carrier/Country Specific Code).

Note that you might need to make at least a 5 minute call using a SIM originating from the buying location to unlock usage of international carriers' SIM cards. Also make sure all the needed bands for connecting to the network of your carrier (most phones support all bands, so no real problem there).

All these note are also printed on the package, in the user manual or both.


phone doesn't boot after installing launcher

Reboot in safe mode. Once in you should be able to delete the launcher.


How do i fix a white screen after replacing digitizer on Nexus 7?

Are you sure that both your screen and device are functioning, and the problem does not lie directly with either device but the connection between them?

Start diagnosing your problem by finding out whether the screen works correctly (with another device), or the device works on it's own and it's not a problem with the motherboard (another screen)?

Also try contacting the company that you bought the screen from for troubleshooting instructions and double-check you've setup the screen with your device correctly.


realme X50 5G - Restarting Each Night At ~3:00 AM

So this isn't really a fix, but it's a work-around that seems to stop the device from restarting in the early morning.
I'm using the "Automate" app to keep the CPU and screen alive. There are community flows that do just this if you search, or you can easily make it yourself.
What I don't know that I'll test tonight is if I can let the screen turn off, but keep the CPU awake. I'll report back how that goes as I'd rather not keep the screen on, even if it's super dim.


Omnirom is already rooted, if anything you might have to install SU.

as to the problem with your primary ROM on multirom, reflash the primary over the top of itself, then when complete install multirom again. As long as you didn't wipe data, your other ROMs should still be intact.....my primary ROM in multirom got glitchy, so I did what I recommended to you and its working perfect again


Can it be that you have unchecked certain contacts to be displayed ?

Go to contacts, press menu, more , display options and verify that you really display the names you want from the options on that screen.


Move the pointer and control it with the head

Welcome Stéphane! Although I am not personally aware of such a system, I imagine at least one does exist. Accessibility functionality on Android is fairly advanced, and I have a hunch a system exactly like what you describe is available. I'm sorry I can't be of more help in that regards.
As a possible simple alternative, years ago a quadriplegic colleague of mine was a computer programmer at a very prominent tech company.  He would strap a pencil-like device to his forehead using a specially-designed headband and write computer programs.  Instead of a pencil tip, the tip of the device was more like an eraser.  Back then, there were no touch screens, so he would be pressing physical keyboard keys.  I wonder if something similar would work for you, but with a tip that works with touchscreens.
Another quadriplegic friend had short 10-15cm (4-6") arms that were rounded at the ends. At the ends of each (or just one... I don't exactly recall) small appendage, was a small ~1cm cavity in which he could attach tools, including a similar pencil-like device (with an eraser-like tip) which he used to type.  He even drove a customized vehicle (a large van that had a wheelchair lift).
I don't know, but maybe some of the above gives you ideas!
I also have a hunch that organizations that help quadriplegics and paraplegics would have good resources for exactly the type of system about which you inquire.  I know that for people with very limited vision or blindness that there are some amazing organizations that help locate (and possibly help fund) obtaining tools like you describe to help accommodate their needs.  I imagine (and hope) similar organizations exist for quadriplegics and paraplegics.
In summary, I hope someone else here will be able to offer you a more specific answer to you question, but in the meantime, that at least a little bit of what I wrote will be of help to you.


How to set the Data Billing Cycle to one day in Nougat?

I reckon it is difficult to adjust the billing cycle to 1 day (if possible). However you can try third-party applications such as 3G watchdog, which is much flexible in terms of adjusting billing cycles (daily/weekly/monthly or custom cycles)

For instance, you can set a daily data plan which of course expires on next day, to start a new cycle (with option to carry over any unused data to next period:

Additionally, there are widgets which reflect current data used, and amount left.


Android keyboard and play store not working

You can fix Android Force Close Error by going through the solutions given in the presentation tutorial. Find it here http://www.slideshare.net/StenaGlass/android-force-close-error-fix

I am hopeful that you will resolve your problem as I have already fixed it!

Wish you best of luck.


In terms of non app data, just plug it in to a computer, and move it over. Just go to your device in an file manager/explorer, and copy the pictures, DCIM, Download and Music folders to your pc. Then, if needs be, you can copy them back.

App data will be different. Assuming you have a Google account, just sign in to it again when you get it back(if it has been reset), and it will re-download the apps automatically. If they have cloud save (most games do) it will re-download his progress.


You can compare your situation with the screenshots in our adoptable-storage tag-wiki: what's going on here is Marshmallow asking you how to deal with the card (it asks only once). If you chose to use it as "internal storage", indeed all its contents will be deleted (see tag-wiki again for details). But if you chose to keep it as "portable storage" (i.e. the same way it was used before), your data on it will remain intact – as Death Mask Salesman just confirmed in a comment on the question itself.


How can I fix the GPS on my Samsung Galaxy S?

Four ways: Upgrading the software, fixing the hardware, resetting the GPS settings/data, and using "fake" GPS.

Upgrading the Software

Samsung definitely released some bad GPS firmware, which does not help things.  Fortunately, good code is included in all of the recent 2.2 updates.  If you can, upgrade your software to 2.2.  It has many advantages besides just the GPS!

You can also try flashing 2.3 GPS code (see this XDA thread).  Apparently it's the best yet, and should work with any ROM.

Summary: Gingerbread great, Froyo good, Eclair bad.

Note: A minority of users have worse GPS performance after upgrading to Froyo.  If you have the very latest Froyo update and this is true for you, I believe you can fix it by continuing with the other steps below (or the 2.3 GPS code above).  You probably have bad GPS data and settings left over from Eclair, or perhaps it's just that your phone has been "cold started" and the GPS needs to collect some information about the nearby satellites first.

Fixing the Hardware

This might void your warranty, though if done properly it should be undetectable.

A major problem for many users is, yes, a hardware problem -- but not a GPS chip issue as some have claimed.  I was reluctant to accept this myself, but after trying everything else I finally resorted to this fix, and it worked!  The hardware has apparently been fixed in newer device versions, so if you bought your phone after October 2010 I recommend trying the other steps before doing this.  But the good news is that it's easy to do.  There's a detailed guide on XDA; here is the quick version:

Take off the back cover; remove the battery, SIM, and SD card.
Remove the 7 small screws in the back of the device, and carefully pry off the backing plastic.
You'll see 4 gold-ish contacts sticking out, approximately at each corner of the device.  You'll notice that the backing plastic has 4 flat contacts on it, which are supposed to touch the ones on the device.  (See the guide for details).
Slightly bend the contacts on the device upwards (a millimeter or so should be good, don't overdo it) so that they will contact the backing plate, like they were intended to.  You might want to insert something like a small folded piece of paper under the contact, so that it doesn't bend back down.
Put everything back together, and continue with the next section.

Fixing the Hardware (2nd option)

This really voids your warranty, but seems like the best possible technical fix so far.

  Problem is caused by bad gnd conductivity between mainboard and antenna. It is conduced by conductivity rubber. This kind of rubber was used for old nokia 8210 for connect display to mainboard. It was the mayor fault for nokia 8210.

There are 2 different methods which both require soldering skill but are said to significantly improve the GPS signal. Read more, see photos and a step by step guide on XDA.

Reset the GPS Data and Settings

Start up the phone, shut off GPS, and install GPSRestore (alternate non-Market link) and Captivate SGS Tools (don't worry, for our purposes it works for all SGS models).
Open the SGS Tools and, from the Secret Codes menu, go into GPS-Test and settings (LBSTestMode).
Hit Delete GPS Data.
Run GPSRestore.  I suggest running it with GPS off first, letting step 2 fail, then going outside, turning GPS on and running it again.  It may take 5+ minutes while your phone searches for satellites and figures out where it is.  This "cold start" should prep your phone with good data, and future locks should be much quicker.
Once the test is done, you should be good to go!

I recommend only trying the following if your GPS is still slow or doesn't work after trying everything else; in most situations the default server is fine.

Go into SUPL/CP Settings (in LBSTestMode as above) and change Server to supl.google.com (port 7276).
Install GPSTest, go outside, turn on your GPS, and open the app.  Wait for a lock; again, this might take some time.

Using "Fake" GPS

Even the best GPS doesn't lock on instantly.  You can use "assisted GPS", or aGPS, to help get a rough fix quickly while you wait for the more accurate GPS to get a lock; this only works when you have internet access, since it uses your IP address to locate you.  Go into your device's GPS settings (Settings -> Location and security) and make sure Use wireless networks and Use sensor aiding are both checked.  Use GPS satellites should, of course, be checked also.

Note: This might make things worse in situations where the phone relies on the inaccurate aGPS more than the "real" GPS.  Experiment with and without it.

And that's it!  I hope this guide works for you and you enjoy your newly functional GPS.


Displaying profile photo on others' phone when called

You can not do that. It is not possible to set a profile photo for yourself on other phones. Phone calls transmit nothing but your voice and phone number. You can not transmit a profile picture through a phone call. Third-party apps like Google Hangouts do not use phone lines, instead, they use data, so they use a custom protocol that allows them to send the profile pic of the caller.
The receiver of the call must set a profile photo for you. This must be done for everyone that you want to see the profile photo of:

For iPhone users: http://osxdaily.com/2015/11/07/assign-photo-to-iphone-contact/
For Android users: http://www.howtogeek.com/259513/how-to-change-contact-pictures-in-android/.

They will want to follow the instructions to add a photo to your contact, not theirs.


If the rubbish/random images aren’t in the camera roll on your phone, how are you determining they are coming from your phone?

I’m wondering if one of two things is going on:

you’ve not signed out of google+ on some other device and that device is doing the uploading (sold or given away a phone or computer? used a machine or phone of someone else’s?) or
you have a security app installed and the app has been activated and taking random images (and helpfully sending them up to google) to help you nab the “thief”.


Contacts, asking to Block or add to contacts

If Android Version Marshmallow or above, you have to give permission.

Go to Settings
Apps
Whatsapp
Tap on Permissions
On Contacts permission and check.


Recovering google authenticator codes on a broken phone

You cannot recover codes from this app as it produces new ones every minute and doesn't provide Backup codes functionality. Perhaps, file recovery software might help you in recovering them from laptop but that's more like an opportunity lost here.

I always have my backup codes saved in a cloud in case any tragedy occurs.


Problems installing Lineage OS 14.1 on Lenovo P2 (black screen/blue LED)

OK, fixed - in the end I did this:

Tried "flashback" to stock android 6 with this zip file.

That didn't just work, so I tried with the automated script "flashall" in the zip.

That failed for the partition/image prov/prov32.mbn with the error message:
FAILED (remote: Do not allow to flash Bootloader image on Unlock device)

I then went into the
PRODUCT_CONFIGURATION_KUNTAO_ROW.xml file and looked at the command list.

I then executed all remaining steps except the ones to delete partitions, for instance

<KUNTAO_ROW_IFLASH>
...
<step operation="flash" filename="prov32.mbn" partition="prov"/>
(first failure in script)

<step operation="flash" filename="sbl1.mbn" partition="sbl1"/>

became

  fastboot flash sbl1 sbl1.mbn (failed with same error)

<step operation="flash" filename="sbl1.mbn" partition="sbl1bak"/>

became

  fastboot flash sbl1bak sbl1.mbn (worked)

and so on all the way through, but skipping the instructions to erase (although I would have done it if the phone didn't start up). It did and I now have ROW (Rest Of World or normal) firmware rather than a carrier-specific version blocking OTA updates due to compatibility with one of their own apps.

I could then pick up a series of normal OTA updates from Lenovo, including Android 7, so I now don't need Lineage OS to get an upgrade for this device (at least not before they do an official Android 8 ROM for it :) ).

It looks like your bootloader or recovery has been messed up. Were you trying to flash anything while this happened?
Best way to fix this is to get the phone in "Download Mode," then flash a new bootloader or recovery. To enter into download mode, press and hold the volume down, home and power buttons together until you enter the download mode. From there, you can flash a new recovery image over. Make sure the recovery image is specific to your phone model.


Nexus 5 full disk encryption stuck 12 hours in?

Could it be that your device is rooted? If yes, google a bit, there are some tutorials which could help.
In that case killing or deactivating SuperSU (or similar) could bring success.

Here is what sometimes seem to work (answer is from aikidork):

Install Busybox (I have Stericson version), RootExplorer file manager, a terminal Emulator (or enable USB debugging), and SuperSU (no promises about this working on other root managers!)
Set up a fingerprint lockscreen. Configure ALL your fingers you want to use ahead of time since this won't be configurable later!
Using Root Explorer, copy/backup the following files to external SD:

/data/system/locksettings.db ,

/data/system/locksettings.db-shm ,

/data/system/locksettings.db-wal
Kill all running apps.
Launch command prompt in ADB or Terminal Emulator.
Execute su so that your prompt changes from "$" to "#" (you are now root)
Kill the SuperSU daemon to temporarily disable root mode (lasts until reboot):

pkill -KILL daemonsu
Your root daemon will kick you out of privileged status during shutdown, changing "#" prompt back to "$" (root is temporarily disabled).
DO THIS STEP IMMEDIATELY without rebooting or launching more apps!
Go to the default security screen and select Encrypt Device. Set up
a password lock screen as required (8 digits with at least one
number). Plug in to power if not using ADB. Confirm the encryption
operation.
If everything is working well, you will see the encryption screen,
 a soft-reboot splash screen, and then a progress indicator counting
 up to 100%. If it moves beyond zero, congrats your encryption is
 working! Wait for this to finish.
Now, to restore the lock screen, unlock the phone and launch your
 Root Explorer again.
Restore the three files you backed up earlier to their exact
 locations, overwriting the replacement ones that the encryption
 setup created.
Wait for phone to lock (or reboot once more) and confirm that you
 can unlock the phone with fingerprint.

PS: I currently have the same problem but none of the mentioned solutions helped so far.

UPDATE: This seems to be a common issue when an app is still holding open files. However, there is no official way to determine which process is causing these issue so far and it is recommended to have a chat with the support.


How do I know if my phone's touchscreen supports Electro Magnetic Resonance (EMR) technology?

If you scroll down on your linked page to the Noris Digital stylus, there is a section on compatibility which links to this pdf document

The only mobile device I recognize are the Samsung mobile devices supporting S-Pen.

Your alternate Bamboo Tip link also has a compatibility document: https://www.wacom.com/en-us/comp which lists support on all of Bamboo's devices. The Bamboo Tip section lists a number of Android devices: like the Google Nexus 5X, Amazon Fire HD 10 (7th generation), Samsung Galaxy S8 as well other manufacturers. This tells me that the Bamboo Tip is capacitive and should work with most phones (unless using the older resistive screen for speciality devices).

As to how the Bamboo Tip can handle palm rejection, I can't be sure, but expect that it is still limited to what the device is capable of, as app developers typically depend on the system to handle errant touches.


How can I circumvent regional restrictions in Google's Play Store?

Try the Market Enabler app (download the APK and side-load it.)  It allows you to spoof your region, so that the Market thinks you're in the US.

As an alternative, you may want to see if this app is available via other distribution methods, such as from other reputable markets (e.g. Amazon Appstore, SlideMe.org, GetJar.com, etc.)  Also reaching out to the developer can sometimes help.


Where does Android get its DNS information when connected to Wi-Fi?

Thank you all for the comments. They helped me work it out.
I'm not 100% sure of the cause of the behavior. It stays even when I switch off 4G and restart the phone. In the post linked to by Irfan Latif it is suggested that Android favors IPv6 dns servers. That could be the cause since my network is IPv4 only.
But the hairpin NAT provided the solution. (Called NAT Reflection in pfSense) After enabling this, things started to work.


Enabling both normal wifi and wifi hotspot to get RSSI values of wi-fi hotspots

What you probably want is your phone work as adhoc and as an AP at the same time I guess it's called bridging
http://compnetworking.about.com/cs/wirelessproducts/f/apbridgingmode.htm
I don't think that at first android phones support the adhoc mode at all yet.
https://stackoverflow.com/questions/1932150/can-android-do-peer-to-peer-ad-hoc-networking
The bridging is only possible for normal wifi routers not for android phones. Routers also support WDS http://en.wikipedia.org/wiki/Wireless_distribution_system
There's no such thing as WDS for android phones yet AFAK.

hope it clarifies the matter abit. thanks.


What needs to be set up in an Android device from another region for a Russian user in Russia, and how?

Simple things

The obvious group of settings that needs to be changed (simply by selecting the appropriate value) is the interface language, time zone.

Keyboard

One unexpected difficulty is the input method.

The factory Samsung OS (from another region) doesn't include a Samsung Russian keyboard, nor does it include the standard Android keyboard (which might have a Russian keyboard). Further complication: The standard Android keyboard cannot be installed separately!

As a solution, I chose to install AnySoftKeyboard (which is also available on F-Droid, which guarantees it is free/open-source, can be rebuilt from sources, and has been inspected by more people for not having spying features). Then in its settings menu, I chose to download a Russian pack.

Mobile networks and internet

For internet to work, one needs to set up an APN (for example, for Megafon, a Russian mobile operator, one needs to add a new APN with "internet" as the value for the field "APN" -- the only essential field; and select it).

(Regressions)

(Still, as compared to Samsung Galaxy S sold in Russia, this one has much more unstable connection to the mobile network (loses the connection, i.e., is offline very often). Perhaps, this can be solved by upgrading the ROM/modem firmware from the present Android 2.2 I9000XXJPK (kernel 2.6.32.9) FROYO.XXJPK.)


Can I track my phone if the thief has reset it?

No, there isn't. There are third party apps that were able to do this with root (unless the thieves flash a completely new rom/firmware). However, you would have had to install that beforehand.

And why there isn't? I think it's for privacy concerns. Basically, Google/Redmi cannot know if the phone got stolen or just sold. So tracking the phone might be in conflict with local law. Also, sometimes the law values privacy concerns higher than simple cell phone theft. Therefor, even in that case it would be against the law to track the phone.

So again: no, it's not possible. Unfortunately, there's nothing more you can do.


You'll need to "flash" the firmware on the phone to stock firmware to overwrite everything (including system files) that you had on it before.

Go to http://www.sammobile.com/ and enter your device model number. You'll be directed to a long list of each country variant of every Android version made for the device. If you have a preference for version, (AKA you hate 5.0 Lollipop), then download 4.4 Kitkat. This is a good 3 hour download, and you may have to download it multiple times before you get a perfect download (MD5 matching file). Also, sammobile requires you to sign up before you download. It's not a big deal, I used my real e-mail.

You will then download Odin v3 from XDA onto your computer as well as the Samsung USB Drivers (Official link) and install each.

Boot your phone to Download Mode (by pressing Power + Volume down) and hook it up to your computer. You'll then click on the PDA button in Odin and find your .tar file. If your download is a .zip you'll have to extract the zip. If you're below Windows 7, the zip extraction wizard will appear to have frozen for about 10 minutes. It takes much longer than usual with a single .tar file.

Make sure all the checked boxes are as so:

..And flash!

When finished, it may or may not boot right up! If not, go into stock recovery (by pressing Power + Volume up) and "Clear Dalvik Cache". Now, your phone should be up and running. If not, clear data as well.

Hope this helps!


When an app is moved to an external microSD card, to where is it moved?

Apps installed on the SD-Card are stored in the ".android_secure" directory.

You cant see the APK files directly in that folder because the it is encrypted to prevent direct access to the APK file of paid apps.


Where is the Samsung Galaxy setting for answering lock/unlock?

lock options for your device, from the Home screen, touch Menu Menu key > Settings Settings Shortcut > Lock screen > Screen lock.W hen you select the Samsung lock feature, Swipe (or the With swipe lock option), additional features become available by opening Settings Settings Shortcut > Lock screen > Lock screen options.For any other query you can check at Samsung India site.


What information is available to an app from the magnetometer?

Magnetometer reports the magnetic strengths on the three axes of the phone. Can work as compass , metal detector and can also be used to increase mapping accuracy.


How can i stop Android OS updare after tapping "INSTALL OVERNIGHT"

Yes, there is an app or settings dedicated to handle OTA updates by visiting that app/settings one could easily choose to install now/schedule installation time/install later option.

This app/settings may vary brand to brand. So, there are all possible ways:

Open Settings-About Phone-Software Update.
Open Settings-Software Update.
Open dedicated app from app drawer( app name vary from brand to brand e.g. Updater in Xiaomi).

If in case homepage of the app doesn't show you any of the above written option. Please tap 3 dots on the upper right corner of the screen, there you will see options and choose accordingly.


ClockworkMod needs to be updated to properly understand Android 4.2's new filesystem structure so it can see its previous backups.

Technically, everything stored on the sdcard is actually stored under /data/media, however Android uses bind to essentially make a really fancy shortcut to various other places. This includes /storage/emulated/ and /sdcard.

As for deleting, without knowing the errors you were running into, it limits my options on recommendations. But you can use adb to delete files (with the code below, replace "old-backup" with the folder name containing the backup you want to remove).

adb shell
su
rm -rf /data/media/0/clockworkmod/backup/old-backup


ADB screen record command to mirror Android screen to PC via USB

To know where the file is stored (if any) then you can use Process Monitor (on Windows) to see where this file is created.


New "On cbvl" notification on lock screen

Figured it out.

My pocket was busy. It went to:

Apps> Settings> Lock Screen> Owner Info

And checked the checkbox, and then closed everything out.

Nothing nefarious. My owner name is just apparently "cbvl", and my lock screen was telling me that.


How can I search for a specific string in an email thread in Microsoft Outlook for Android?

Unfortunately, it is not possible as of today with Outlook version 4.0.90.

You can always open the mailbox in your web browser and use the Find in Page functionality.


Make Galaxy S7/Android install drivers for MTP (Nougat, Win 7)

Try this:

Open the dialer
Type *#0808#, should open the USBSettings menu.
On the window that comes up, on USB, tick AP. On USB Settings tick MTP + ADB
Reboot the phone. Windows should now install drivers and the phone should be detected in debugging mode.

  Can I make Nougat's developer settings' USB debugging default to PTP? Every time I unplug the phone, Android sets it back to MTP.

Try:

Pull down the notification panel
Then touch the USB sticky notification
Select Tranferring media file (= MTP)

Your phone should remember this setting and never forget again :D

UPDATE:

Try *#9090# and select DM/DUN over HSIC

Also try revoking the USB debugging authorizations in the Developer options. Works fine in most time.


Is there a reliable way to tell if my call is blocked by the call recipient?

You won't be able to tell this information: the target phone could be switched off or unplugged for example.

SignIn to Youtube (Android App) with Gmail but without adding Account

You tube is Google owned and therefore, is closely related to the purchases you make, your viewing habits which are monitored by Google (read ad and revenue generation). So, the tight coupling is inevitable as answered here
That leaves you with the option of signing out of Gmail  (of the youtube related account) or  use alternative approaches like FireFox addon or IMAP approach so that you have mail access as also youtube stand alone

It's a workaround


Is Restoring a previous backup results to happen bug again

No backups are not connected to hardware problems. Hardware means physical part/s of the device. The backup is software, by that I mean the non-physical part (or correctly data).

If you want detailed, please write us what was the problem with you phone. What did the service sad about the problem.


My phone (Google) thinks I live in a town that doesn't exist

I noticed recently that both my husband's M9 and my M10 started displaying Brooking Township instead of Raytown. I'm close the Kansas City city limits and I share a zip code with that city so I'm accustomed to having the wrong city display on occasion. However, I did some research and residents of a small area of Raytown named their area Brookings Township. When the city was finally recognized as a city, the official name was set to Raytown. I live on the opposite side of the city with respect to the area that was once known as Brookings Township. I found a US website with all the information about US towns lists and the township was archived as soon as it was recorded for historical purposes. I did a quick poll via the NextDoor app and everyone that has responded verified the same issue began within the last month, for various device models and service carriers. It feels like a purposeful change to jack with us or something. Or it is just an interesting weirdly targeted defect in some part of the software.


Is there a way to block access to or wipe my Google data for a lost/stolen phone

EDIT: I now personally use AndroidLost. In addition to everything listed below, there is also an AndroidLost Jupstart app that will launch the service remotely if your phone is already lost without any locating software on it. It's pretty sweet:

Read SMS'es
Read the latest SMS'es from your phone and send them to your email.
Remote control alarm
Have you ever misplaced your phone which was put on silent mode? Now you may sound the alarm on your phone from your PC!
View on map
Find the location of your phone on a map. With AndroidLost you can find your phone with GPS precision. Even if the phone is indoor you will get a nearby location by network accuracy.
Send SMS'es from your PC
You can send SMS'es directly from your phone by typing them on AndroidLost. All replies will still go to your phone.
Lock the phone
You can lock and unlock the phone from the web. If you forget your pincode you can simply overwrite it or remove it by entering an empty pincode on the web.
Wipe the phone
Don't want your personal messages in the hands of anyone else? With AndroidLost you may wipe the entire phone so all SMS'es, contact and google setup is removed.
Pop up messages on the phone
Send a message to the friendly guy who have found your phone so you may let him know where to give it back.
Forward your calls
You can send keys to the dialer of your phone. That way you can forward your calls from your mobile to a nearby phone.
No battery use
AndroidLost will not use any battery since it does not poll any server to find out if it is lost. It uses the latest technology from google to send messages to the phone.
No pre installation required
You didn't install AndroidLost on your phone? No problem! You can push the AndroidLost app to your phone from google market and initiate the connection to googles servers by sending an SMS with the message "androidlost register" to your phone.
Read status
Detect how much battery is left, display IMEI, SIM card ID and much more.
SMS commands
You can set up a phonenumber which can control you phone, i.e. start the alarm by sending an SMS to your phone.
Erase SD card
Click a button and your SD card will be erased! Very useful if you have some naughty pictures on your sd card.
SIM card changed
When the SIM card is changed an email will be sent to the owner of the phone.
Hidden SMS
When the phone receives an SMS it plays a sound and displays an icon in the notification bar. But if it starts with androidlost it will not play any sound and not display any notification.
Call list
A list of incomming and outgoing calls will be sent to your email.
Camera
AndroidLost can take pictures with the front facing camera in case the phone is stolen. Only for android 2.3.
Tablets Honeycomb
I think I have fixed it so AndroidLost works on tablets. The call functions will obviously fail if the tablet have no phone installed.
Text to speech
You can make your phone speak out load. Suppose you have lost it on a café then you can make the phone say: 'I am lost - please pick me up!'
Multiple phones on the same account

Here are some others you can use:

SeekDroid does the following:

Locate your device
Remotely Enable GPS
Display its location on a map
Audible alarm (even on silent) w/ custom message
Lock device w/ custom code
Retrieve recent calls
Remotely wipe entire phone
Remotely wipe SD Card
Hide from app drawer
Disable App from being uninstalled
Virtually no battery drain
Works without a SIM Card
Reteive SIM ID, IMEI, and active phone number

and WatchDroidPro does the following:

Get your phone position (by network or GPS)
Retrieve current SIM information (useful when someone put another SIM card in your phone)
Share your position to friend
SIM substitute protection
Make it ringing even if the ringer is off
Wipe data
Lock your device

All of these should do what you're looking for :)


I've just checked that again: "Error -24" in most cases is caused by a failed install/update. To solve it, uninstall the app from your device. After that, you should be able to install it again.


Is there an Android web browser which can upload files from a local file system?

The stock android browser, as long as the website uses a file upload control it can.

I just used the upload tool on twitpic, which uses flash, allows me to select audio, video or image files, and uploads them to twitpic.


As far as I know, there is no such app. But you can still solve your problems. There are many keyboards available to try out whose auto-correction features are totally acceptable.

You can try these from Play Store:

Swift Key
Fleksy
Swype


Do I need an SD card to add apps to an Advent Amico Android Tablet?

You could try emailing them to yourself or downloading them from somewhere (Dropbox public link or a web host of some sort). On most (if not all?) devices you can just launch an .apk after it's been downloaded and it will open with the application installer.

You'd most likely also need to allow "Unknown Sources" for this to work, which should be found in the settings menu under Settings->Applications->Unknown sources.


How do I unroot my Evo (using unrevoked 3.21)

You could start with this method. It's basically just two steps:

If you used Unrevoked Forever on
your phone, then flash their S-ON
tool.
Flash a stock PC36IMG.zip
from HBoot.

There's also the RUU method, though I think you'd still need to run the S-ON tool if you used Unrevoked Forever (I don't believe the RUU will re-enable S-ON). Either one of these should get you back to a stock unrooted system.


How to disable wallpaper blur effect on Samsung Galaxy S9 home screen?

Whatsapp: iPhone to Android: 0 messages restored

It seems like Wazzap Migrator was the answer, it costs money to restore media as well.

To extract the conversations + media:
1. Download the free backup extractor http://www.wazzapmigrator.com/faq/free-itunes-backup-extractor-windows.
2. Open it and select your iPhone (it should be plugged in to your PC of course).
3. Go into advanced and check "Applications".
4. Click "extract selected files".
5. The conversations should be stored in "Desktop\Extracted from backup for WazzapMigrator\Applications\net.whatsapp.WhatsApp\Documents\ChatStorage.sqlite"
and the media folder in "Desktop\Extracted from backup for WazzapMigrator\Applications\net.whatsapp.WhatsApp\Library".

Make sure your have to paid version of Wazzap Migrator installed on your android phone. (Or you will only be able to restore conversations without media).

To put the extracted conversations + media on your android device to select in Wazzap Migrator:
1. Plug your android phone into your PC.
2. Go into your phone's internal storage via Explorer.
3. Create a folder, named anything, and drag ChatStorage.sqlite and the media folder into it.

To restore:
1. Install Whatsapp.
2. Open Wazzap Migrator.
3. Select your conversation file and media folder manually.
4. Start the conversion.
5. Reinstall and start Whatsapp.
6. If it detects a backup in your devices storage, tap restore.
7. That's it.

Keep in mind that my memory of what I did is sort of fuzzy. You should know what to do, however.

Flashtool gives DOWNLOAD OK but the tablet is not booting anyway

If you downloaded even the preloader.bin your device is done with but if you never ticked preloader that's incompatibility issues between the ROM and the phone


How to see which applications are saved on phone

In the settings option you have Application Manager. In Application Manager if you swipe to the left you will get apps installed on the sd card. It should look something like this:


How do I disable notification sounds and vibrate in messenger?

As of now, notifications for chats and calls in Messenger are grouped and can only be enabled/disabled together.
Your best bet is to contact facebook/messenger and ask them to add the feature, by splitting the notifications into channels, which can then be controlled seperately.


How to upgrade a phone with only 8Gb. internal memory

Well, I finally found out about what happened, after learning a bit more about how Android works. It turns out that, although the bloatware apps are installed in /system, their updates are installed in /data. In other words: Google and Sony's bloatware not only eat up space in your system partition, but also in the space that is supposedly for the user.

What I did then was to disable every unnecessary app, and hit the "revert to factory version" option (don't remember the exact wording). This way, although you can't delete them from /system nor shrink said partition, at least you free up internal memory. After doing so, we had more than 900 Mb. of free space, and so we could update the apps that my relative actually wants to use.


Playing subtitles - and only subtitles - on Android

After more searching, I found SubtitlePlayer in the Google Play Store.

It seems to work adequately for what I need, but because its name is two words jammed together, doesn't show up when you search for "Subtitle" in the market.

Also, the page says it needs 'Unicode' subtitles; after a few tries, I got it to work correctly with UTF-8 encoding, without a BOM.


disabling sms content and just seeing name on the lockscreen

I do not have an HTC One, but I use Go SMS Pro which is a third party SMS/MMS app that has a easy setting in there to only show a "New Message" notification instead of actually showing the message's contents. You said you didn't want another application, so you might be able to look through the settings of the default messaging app on the One and see if there is something similar.

If not, I highly recommend Go SMS Pro to solve this issue and several others.


Can one avoid losing everything on a Galaxy Nexus when applying a new ROM (safely)?

You can use adb backup command to back-up everything to your PC. Use this manual on XDA for correct parameters.


How do I keep capitalization I put in? My Galaxy S7 switches it to lower case

Being that autocorrect is on, your keyboard will naturally change words to lower case when it sees fit. Being that the examples you gave, are regular words which are written in lower case,  the keyboard will not differentiate between the times that you mean to write the name of a city or just an English word. As for your dogs name, i would imagine that you wrote it once and now it's saved in lower case

Here are two things to try:

Add the upper case word to your keyboard dictionary.
To add a word to your Swipe keyboard, all you have to do is write the word a few times, and the keyboard will get used to it.

In your case you should type the word 'Stone' in upper case, and before you press on the space bar, press on the word on the suggestion bar where the word appears in orange font (as shown in the screenshot). Do this 2-3 time for each word. This way the keyboard will "learn" the word, and will not correct it next time.

Remove the lower case word from the keyboard dictionary.
Type the word in question, then before pressing the space bar, long press on the word in the suggestion bar and select 'remove'. After successfully removing the word from the dictionary write it again in upper case, and you should have an option to add it to the dictionary. If there is no such option, then write the word a few times in upper case till the keyboard 'learns' that this is how you want it.

Note: from now on, when you write the word mountain it will automatically turn into upper case even if you didn't mean to write the name of the city.

Hope this helps.


Mute text notifications for single conversation only

If it is your app, then you could provide a provision for this by maintaining a flag. Else, if it is Android's SMS app or Hangout, then long press the conversation. It will provide mute notification option in Toolbar.


Can PowerTutor app measure exact whole power consumption of device's GPU?

As already mentioned, Power Tutor doesn’t display power for the GPU. Power Tutor is a very cool app, but it's based on research that was done in 2011. It uses modelling to estimate power consumption. No actual power is displayed. Power Tutor is surprisingly accurate when it is run on the phone that was used to create the model, but that phone (the HTC Dream) was released back in 2008. According to Google Play, the Power Tutor app hasn't been updated since April of 2013.

On my Samsung Galaxy Note 3, Power Tutor only reports LCD and CPU power and both are very inaccurate. The actual power consumption of my device when idle is 528 mW. Power Tutor says it's 623mW to 818mW. That's an error of up to 55%. The per-rail estimates are off even more. On my device it shows the GPS uses up to 400mW. That's an order of magnitude off. It shows my audio power usage is around 350mW, which is also way too high. Power Tutor shows my screen uses a little under 600mW. That's too high. It shows the processor uses around 0-150mW. That's too low. On my device the per-rail WiFi doesn't work.

It's true that Android has power profiles, but those don’t appear to be accurate either. I can provide more details if anyone cares.

A better way to measure total system power is an app called Trepn Profiler. It doesn't estimate power. It reads the actual current and voltage from the power management IC and converts that to into power. Because it runs on target, that does make readings a little higher than they should be, but it’s a very useful tool for this who are lucky enough to have a device that reports accurate battery power.

If you have money to burn and you want to measure accurate per rail power of the CPU (Cores 0-3), CPU (Cores 4-7), Graphics (GPU), LCD Backlight, Front Camera, Rear Camera, System Memory (RAM), Internal Memory/SD Card, Wi-Fi/Bluetooth, Sensors and USB, you could get a Snapdragon MDP tablet from Intrinsyc. I don’t want to provide more details here because I know this isn’t a commercial forum.
In the unlikely event that you are willing to share both versions of your app with me, I’d be happy to let you know what the power consumption is of each. You could also get a Monsoon Power Monitor and measure this for yourself.

Disclosure: I’m part of the team who produced Trepn Profiler. Trepn is free in Google Play. We’re working on a new app that will be released later this year that will also show modelled system power on the most popular mobile processors. Sorry for the blatant plug. I only mention this in case some of you would like to Beta test this app.


Finally, I got a workaround - the Wi-Fi has to be turned off and then the installation over USB works as expected.


How to force a time/date update in my phone?

try this:

uncheck "update from network"
set it to a wrong time (something that's clearly not right)
close settings (not sure if this is actually needed)
check "update from network" again (which should correct the time)


Buying an album from Google Play of which I already have some songs

In my experience... Yes, you will be charged full price for the album even if you already have some songs on that album.  You will not have duplicate songs in your library if the copy of the songs you previously had were from that exact same album and also purchased from Google Play.

However, if the songs you already had were from a different album than the one you are purchasing (eg. a regular album vs deluxe edition album vs a single or an artist album vs a soundtrack with the same song on it), then you will end up with a duplicate copy of that song in your library even if both were purchased from Google.

You'll also get duplicates in your library if the songs are from the same album but from a different source like iTunes, Amazon or ripped from a personal CD and uploaded to Google Music, but in your case you already said they were purchased from Google Play so this added comment is for others that might have this situation.


Batch remove entries from Multiling dictionary

You can edit the file in the preferences (gear symbol), then Misc, then Import/Export and there you find the user dictionary.

I’ve written this down, because I’ve been searching so long to find how to backup my user dictionary of the Honso Multiling O Keyboard.


The best solution I could come up with was to install Power Toggles, and add a shortcut to my homescreen. From unlocked, this is 1 tap. And if locked, because I use fingerprint unlock, it's hardly more than 1 tap anyway.

I can't use root because this is a work-supplied phone, and some required software won't work if the phone is rooted.


Is there an FTP server which supports resuming failed downloads?

Or, if not FTP, and not rsync/scp, but an SSH server (like DroidSSHd, a free/libre SSH server which I could find that would work on my non-rooted Galaxy S with Android 2.2), you could use the simple script rpush-into to continue an interrupted transfer.

In rpush-* scripts, I've implemented the file-transfer through SSH with the help of only the basic cat and ls on the remote side. So that it can be used even if the SSH server on Android doesn't provide scp, sftp, or rsync.


how can I know which Gmail account was on my Android device?

Go to Android Device Manager on your PC and log in with every Google account you have and check what account has your phone in it.
In Android Device Manager just log in, check for the device, if not there, try with a different account.

Screenshot:

Android Device Manager: click here.

Hope my answer helps.


Unfortunately for you, the Android log files use a "ring buffer" (think of it as an Ouroboros), so you might not be able to see the startup logs anymore. But here are some things you can do:

Check the "battery monitor" in Settings. Provided you didn't put your device to charge again since, it should show you how long it's been running without being attached to a charger
Using a terminal app or adb shell, run the command uptime – which tells you exactly how long the device has been running since it was last powered up (should also be listed in Settings › About › Status on your device)
different logs can be obtained via logcat, dmesg, and others (see our logging tag-wiki). On ICS (Android 4.0.x), you also can use Logcat & Co..

Keep in mind that every action the device performs "scrolls on" the ring buffer, so older events get flushed out; installing an app will do so, but the other actions as well: screen tapped/swiped etc. are also events. I'd suggest starting with Settings › About › Status if you're after the time your device was robbed of its card.

As for the modified files: At least the Playstore app periodically checks things in background (not sure about the Youtube app here).


How did I get my Nexus 7 homescreen into landscape?

More of a status update than an answer: Jelly Bean 4.1.2 allows a landscape rotation on small screens.

I previously had the same experience (accidentally changed the rotation but could not reproduce it) -- I received the system update yesterday and was pleasantly surprised after the reboot  :-)


How can I see the upcoming calender event in the always on display?

Go to settings. Then Lock screen and Security. Scroll down to Lock Screen and Always on Display. Select Information and FaceWidgets. Then select FaceWidgets. From there you can select "Today's Schedule" as a screen on Always on Display. (I have the Note 8, but I would imagine you'd do something similar or the same thing.)


Is there a way to switch to charging only before plugging my phone into an USB?

Enable developer options - To enable Developer Options, go to Settings and select About phone. Now, scroll down and find out Build number. Tap on this option around 7 times. You will get a success message
You will find Select USB configuration . Tap on that too open a sub menu and choose Charging only
Next time you connect, it will revert to charging automatically


Google apps losing connection to the servers when on mobile data

This turned out to actually be a network provider problem (in my case: SimpleMobile in the US) and the fix is incredibly simple: remove the proxy server from the APN and everything works.

The final hint I needed was the Google Now error message, googling that took me to this thread on xda-developers.

I have no explanation for why 'clear data' fixed the issue for a few minutes and why this didn't occur when tethering the tablet through the phone (maybe a cached server connection somehow?). It does however explain why the problem occured again when putting the SIM card into the tablet (the APN comes with the problematic proxy as a preset), and that should have tipped me off, I guess.


What actually determines whether I see H+ or 4G in the top panel?

It is the speed that determines what is shown in the indicator
For the conventions regarding the symbols and speed , see this - which are in line with what is mentioned in your question
Advertised throughput speeds are not the actual, real world throughput speeds experienced by the end user. See this for factors affecting the speed

Coming to your main concern regarding different speeds and variance with symbols displayed:

Situation described is India specific and regulated by Telecom Regulatory Authority of India. AFAIK, they are aware of operators delivering lesser speed than advertised and are in the process of streamlining it. Details are being skipped here being broad / opinionated

Does GPS require clear view of sky to lock satellites?

GPS uses radio frequencies between 1 and 2 GHz (L1 signal at 1.57542 GHz and L2 signal at 1.2276 GHz).  These have to get through for GPS to work, which is not the same as visibility.

For example, my GPS (Garmin Etrex Legend HCx) gets a fix on the top floor of the house, below the roof made of tiles, insulation and drywall. It doesn't get a fix on lower floors, where there's too much concrete and steel in between.

BTW, I had a Motorola Defy for a while, if I remember correctly it also worked, but had a much lower precision, sometimes it was hundreds of meters off.
