ADB Restore Stalling on "Full Backup" screen
I just upgraded from a Galaxy Note 4 running Android 6.0 to a Galaxy S8+ running 7.0.  Neither is rooted.  I've used Helium in the past to backup app data. However it's crashing or just not working when I'm trying to restore to the S8+.

I'm trying to use ADB directly to restore the ab files.  I found that the phone is getting stuck on a screen titled "Full Backup" (see below).  A) it says my device is encrypted.  Is it?  I didn't turn on encryption.  B) The "Back Up My Data" button is grayed out unless I enter a password.

I believe this may be the same issue breaking Helium.  What does this mean?  How do I restore backups?

(I still have the Note 4 in moderately good working condition, so I can recreate backup files if necessary)

LG Stylus 2 Wipe cache partition
My friend have LG Stylus 2 quite laggy and need to wipe phone cache

We have already wipe cache from apps with following method

Drag down the notification bar and tap the Settings icon Settings icon.png at the top-right.

Tap General > Storage. (If using List view, scroll down to 'DEVICE' and tap Storage.

Wait for menu options to finish calculating.

Tap Cached data, then tap YES.

Wait for the cached data to clear; depending on size it will take several seconds to complete.

When the wipe is complete, the storage screen refreshes and cached data will not be listed. This means your our cached data has been successfully cleared.

and now we have tried the following method

Power off your device.

Wait a few seconds

Boot in recovery mode by pressing the Volume Down and Power Button at the same time for 2-3 seconds until the LG logo appears on the screen.

Release the buttons and press them again until the Recovery Screen appears

But the option is only factory data reset/wipe all data

How can I access the recovery mode for just wipe cache partition, like other phones like Samsung, Oppo, Asus, etc.?

Any help appreciated

Sony Xperia Z5 Compact black screen
Yesterday I accidentally dropped my Sony Xperia Z5 Compact on the ground (from a height of about half a meter), and it appears to be broken since then. Details:

The screen was clearly on, but showed black. However, it still responded to touch on the places where the buttons should be. Rebooting by holding down the power button didn't work. Force shutdown by holding both the power button and the volume up button did work. When I rebooted, the screen remained black (but was turned on). It still responds to touches on certain spots where buttons should be. When trying to unlock it blindly, I found the emergency call keyboard.

I tried connecting the phone to my computer, and it recognizes the phone, but sees it as offline, or disconnected. I seem to have no way of remotely accessing it.

Is there anything else I can try without having it repaired at a retail store?

Unable to install ADB or any USB driver for lenovo k3 note
I have tried everything that I can think of here, but somehow my Win10 PC won't finish the driver installation.

I tried fastboot mode, recovery mode, MTP connection, USB debugging mode. Win10 fails to recognize the drivers at all. I also tried the universal drivers, they failed too. Just "Install failed" message when I use universal drivers.

I also tried removing all USB device drivers, but that didn't work either. So, right now, my phone is stuck in a weird position. I can't fix my IMEI issue because I can't connect to PC. And I can't connect to PC because it does not get installed properly. Device is getting detected but the device manager just shows error saying "A file could not be found", or "An installer cannot perform installation". No proper error code available here, but I can definitely provide exact error messages, if that helps.

Error Message in Fastboot/Recovery Mode: Device USB\VID_0BB4&PID_0C01\8PR8EMEEWCOFQ8AI requires further installation.

Edit:
Tried removing every usb driver, then reinstall, then use Lenovo usb drivers. Same problem. The drivers do not get installed.

Fix null IMEI on rooted phone without pc
So, the biggest drawback is I can't connect phone to PC (drivers not installing on Win 10, separate issue). And in my current ROM, I have already got root setup. Problem is I am getting null imei.

As you understand, I cannot go back to stock, or make any changes in this setup. Because if I mess it up, I can't connect to PC to fix it. I can however copy files to sd card and fix the imei that way.

How can I add the imei info using rooted phone, without a pc?

Edit:

I tried MTK engineering mode app as well. But the engineering mode contains no option for radio information.

Can't share in Google Keep via the app, only via the webpage
As you know, since late 2014 Google Keep allows sharing notes with others.

But I've noticed I can't share in Android (tried in Samsung Galaxy S4 mini GT-i9195i) with another Gmail account. There's a save confirmation with a "viewing shared note" message, but it doesn't actually share. As if I never shared in the first place. It also doesn't auto-fill when I start typing the other Gmail account.

As soon as I try it via Google Keep's webpage, it works flawlessly. It auto-fills the other other Gmail account and actually shares with it.

Any idea why?

问:
How to re-login on android phone after Google Account email changed

What has changed

I have recently changed the master email address used for my Google account. My issue is that my phone (Nexus 5X) is requesting I re-sign into my account, however it is specifying my old email address, and not letting me change it to the new one.

What I have tried

I have tried adding a new account to my phone and logging in with my new email address, for some reason the new account has not got my apps, folders, preferences, background, fingerprints, android pay e.t.c. settings, despite apparently having finished syncing with my google account. The new account is the same account that was logged in previously, so now I have two accounts on my phone for the same account, the old one with all my settings but the wrong email address and log in issues, and the new account which is logged in but has none of my user data/settings. This question suggests doing this.

Turning it off and on again (it was worth a try!)

What I haven't tried

I could add the old email address to my Google account as an extra address, though the email account doesn't actually exist anymore and I'd be left with a phone logged into my account with an invalid email adress, so I'd still need to update it and be asking this question.

Related Questions

This question has an answer suggesting what I tried above, claiming "You don't risk any data loss by doing this" however none of my data synced so that clearly wasn't what they meant.

This question has an answer claiming that if I change my account I cannot avoid a factory reset, though this question does suggest a way around it using 3rd party tools (which I'd like to avoid).

This question and this question suggest updating individual apps, though I have no idea how that would help change the actual email attached to the account in settings.

TL:DR

The main email of my Google account has changed, my android phone insists I log back into my account, but insists I use my old email address (which doesn't exist anymore). What do I do?

Disable wake on fingerprint sensor
I've spent a lot of time editing /system/usr/keylayout/Generic.kl in trials to disable waking on sensor touch.

What I've learned is that MENU and SLEEP "buttons", when assigned to key 353 (which is my sensor) don't wake the device up, BUT they work as actual keys, which is unwanted.

So, what key should I assign to the sensor?
I've tried avr, dvr, virtual, forward, media_close, meta_left, shift_left, escape, insert, button_l and a lot of other things. All of them wake the device, unfortunately.

P. S. Commenting or removing the line doesn't work either

Unable to remove encryption
I have a galaxy note 4 that isn't rooted but has TWRP 2.8.5 installed. I wanted to factory data reset the device, however, I was getting the error that it was unable to mount /data. I read on XDA that I had to format data. I clicked on format data and typed in yes.

I got the message "Formatting Data using make_ext4fs function. You may need to reboot recovery to be able to use /data again. Updating partition details ... done". I see the status as "Data Format Complete Successful".

I rebooted the device, and I know the OS loaded, but I was greeted with the error "Encryption failed, cannot decrypt your device storage. You need to reset your device to factory default settings". And a reset device button. I click on the reset device button, it boots me to recovery and runs a script and again reboots to the previous error.

I tried to factory data reset it now, although it showed as successful, I was directed to the same error.
Can you please advise what should be done?

Thank you

Can apps track visitors to your WhatsApp profile?
There are apps called "WhatsApp Tracker" or "Whats Tracker" that claim to display new visitors to my WhatsApp profile.

I tried those apps and turned out the apps didn't do what they claim. I am not sure about the logic behind the design for it to accomplish this function.

In my humble opinion, it is not possible with the current WhatsApp infrastructure to track down visitors who have been specifically seeing your WhatsApp profile (for example: looking at a display picture, watching status updates)

Is this really possible? Is the above-mentioned app genuine? I did not find it so... But if it is even scarcely, then what logic helps to track down visitors?

What config files are involved in master volume levels?
I recently took the plunge and installed LineageOS on my Nexus 5X. My hope was that this would allow me to increase headphone volume as my favourite headphones are not loud enough with the stock volume controls.

After much googling and trying of apps pre-root, I concluded that I would need to delve deeper. I've now tried a couple of methods touted as solutions, namely editing build.prop and mixer_paths.xml but neither of these approaches has influenced volume levels.

I would like to know:

Is this technically possible by editing config files?
Why don't apps claiming to boost volume on the play store actually work?
What settings/files do those apps try and alter?

Although I am specifically looking for information for LineageOS 14.1 / Android 7.1, this information might be useful to a broader audience.

I have tried:

Manually editing mixer_paths.xml and adjusting Headphone volumes in <path name="headphones"> and also editing earpiece and headset values in build.prop.

N.B I am not looking to increase the granularity of control over the volume but to boost the volume level beyond the loudest setting in stock Android

The Android OS is being updated with Internet turned off - how can it be?
A phone has mobile data turned off.

No wifi antennae is connected. We were in the wood, on the hill, minimally 3 km from the nearest village. The nearest, higher hill, has a mobile antennae. So, the mobile signal was on. Even if there was a wifi antennae, I hadn't connected to it.

So, obviously, no Internet connection was active.

But the phone suddenly decided to update the Android OS. And started to download the update. It was even finished - in 5 hours - without internet being on. How could it be downloaded? Will I have to pay for those data? (the phone has no prepaid Internet)

Galaxy S4 getting stuck in bootloop after random restarts
I have had my galaxy S4 for 4 years and the last 3 months it started to reboot randomly. After one such reboot it got stuck on the Galaxy logo in that I had assumed to be a bootloop. If I leave it off for about an hour it gets to the home screen and reboots and gets stuck again.

I have tried:

Factory reset.

Removing and replacing the battery.

Flashed 3 different ROMs.

After installing a new rom the device starts up normally but after a while(at the point of setting up wifi or just seeing the home screen) it would reboot and gets stuck on the Galaxy logo. At this point the phone would heat up a little bit, nothing dangerous.

So at this point I am wondering if its a software issue or hardware.

Any suggestions on what is causing the problem or where to look for solutions would be appreciated.

问:
How do I recover Chrome history when sync fails?
How do I restore the history for the Chrome browser? Do I need to root the device to access the history file and roll it back to a previous time? I was told that there is the possibility that this wasn't a complete delete since that isn't the case with SQL databases.

I wrote a post in the Google product forums for Chrome regarding how to export my Android's Chrome browser's format in a readable format with clickable links/time accessed, etc.

Unfortunately, the advice I was given was essentially, "try sync again." I had tried this several times which did not result in the phone's history getting synced to my account. Because the email I was using was an institutional email, I tried signing into a different email, which instead led to my browser history becoming inaccessible or deleted. I am not sure which. Usually, when I just sign out of the Google account in Chrome, the browser history is restored.

I had found a few threads regarding the location of the history data and others asking how to restore lost tabs and history (e.g. how can I fetch Chrome history in Android 6 Marshmallow? How to export Android Chrome browser history in a file? Retrieve history from Google Chrome on Android, Export Chrome for Android's history) but they either only have a few, general replies, or none at all.

Why SManager can't wake network from sleep?
Here's the situation: I'm using SManager to run a very simple shell script on a regular schedule; all it does is run a ffmpeg command line to save an audio stream from a URL. If I run the script manually, it works great. If I schedule it for, say, 15 minutes ahead, then put the device to sleep, it works great. But if it's been sleeping for hours, like overnight, the script runs but ffmpeg reports that it can't access the network. Only difference that I can see is how long the device has been asleep, but I haven't done enough tests yet to figure out how long it has to be asleep before the network becomes unwakeable.

I've configured my scripts in SManager to get a wakelock and to run as root.

Wifi is set to never sleep.

I've tried deleting the wifi network and reconnecting.

Added sleep 30 at the top of my script in order to give SManager plenty of time for its wakelock to wake up the network.

Added ip link set wlan0 up to top of script to wake up the network.

Tried to install Kernel Audiutor to see if has any useful mods, but for some reason it fails to start on my device.

Tried a Wifi-keepalive app.

I have no "battery saver" apps of any kind installed.

Device is a rooted 5th generation Amazon Fire tablet with Lollipop Nexus ROM (which predates Doze, so that's not the issue).

Does this make sense to anyone; ideas about how to solve it?

Is there a way to turn off translation in Google Play

Any way to stop ridiculous translations in Google PlayStore?

I have an exactly the same goal as the above questions, but my situation is a bit different from above.

I don't want to change my system language (Chinese)

Changing Language Settings for my Google account doesn't work. It does not affect the user interface of Play Store app on my phone.

Tried App Settings, but it doesn't work at all. Maybe Xposed for N is too new.

问:
3 android devices possibly hacked and data compromised. Is it possible for devices to be hacked whilst offline?
In a museum we have 3 android tablets, 1 Samsung tablet and 2 commercial tablets. The tablets don't have internet connection, wifi is disabled, bluetooth is disabled. the tablets auto boot when power gets on, and autostart a fullscreen application to play video's.

A few weeks ago one of the tablets was missing his video files (stored on the external SD card). A few weeks later, one tablet was missing files again and the other tablet has the default videoplayer of android to play video files. After putting back the files everything worked again.

But this weekend, 3 android devices were not working. One commercial tablet is missing the video files on the sd card and .fuse_hidden file was on the external sd card, the samsung tablet is also missing video and photo files, and the other commercial tablet is giving the message Unfortunately, the process com.android.system.ui has stopped.

When I click ok the screen goes black and comes back with the same message. In the back of this message I see a unlockscreen, clock and text connect your charger. So so strange. After clicking multiple times ok, the message disappears but I don't have access to the tablet, because I don't know the unlock pattern, because I did not make that. On the external sd card no files are missing but a extra folder is there with the name .android_secure.

Are the tablets hacked? Is this possible offline? I am really frustrating about this, because I don't know what is going on. I hope someone knows.

Thanks in advance!


问:
Latin American Moto G2 locked in Europe?
I bought an unlocked Moto G2 (2014) in Chile last year, model XT1063. It was new but on display in a store, no connection to any service providers, no contract, no sim lock.
I use CyanogenMod 13, it runs fine.
However, now I am trying to use it in Europe and it won't work with my German SIM card. It says "SIM card is Perso locked" and requires my "SIM network unlock pin".

My Chilean service provider confirmed that the phone is completely unlocked (so SIM unlocking via web services does not apply).
According to willmyphonework.net, the phone should work in Europe.

Any ideas what I could try to make it work?
Thanks!

Screenshots (click images for larger variants)

The network unlock PIN is NOT the normal PIN protection of the SIM card; I use the SIM card in another phone, it works perfectly well.

edit: desperately, I wipe the phone and installed current LineageOS 14.1, but to no avail. The "Perso locked" message now simply reads "SIM card is locked".

4G signal with mobile turned off
Recently I have noticed that my cellular company (TIM, I'm in Brazil) has been charging me for network connections daily. I rarely use cellular network since at home and in my job has wifi and I don't mind being 30 minutes without internet.
I called them and they said it's due the device having its preffered network at 4G, not 3G. When I changed the preffered network to 3g, it stopped charging me. They won't retrieve my money because they received a signal so for them there was an internet connection (even though the data received is like 1kb). It's horrible to keep changing it to 3g/4g every time I need to turn it off or on.

But anyway, my device is a Motorola X Play running Android 6.0.1.
The question is: does Android send 4g signal even with mobile data turned off? If so, is there a way to make it stop?

I know this has been asked before but no real answer has been given.

I think the problem may be with ip problems and not the mac address. If I set up a static ip I can connect to the network but it would act as if I wasn't connected and no internet would be given. I connected to the network with my default mac and got internet access and found out the ip info and stuff and so I tried to spoof my mac address again and then set the static ip as that one and it would connect but yet again would get no internet. This makes no sense to me as it works fine on my computer.</p>


问:
Find out why my Android phone is rebooting
All of a sudden, my almost 2-year-old Samsung Galaxy S5 Neo starts rebooting at random times.

I did some research, and various forum threads on the Internet recommend different "try this" solutions: Factory-reset the phone, remove apps, remove SD card, etc.

Since I am not a big fan on shotgun debugging and I'd rather avoid spending hours to re-install and re-configure everything just to find out that this was not the cause of the problem, I'd prefer a more systematical approach.

Is there a way to find out why my Android phone is rebooting without randomly "trying things"? For example, are there some log files that I can view which can shed light on this issue?

In case it matters: My phone is non-rooted and (for reasons of warranty) I'd like it to stay that way.

In Ubuntu Desktop my Arduino Uno shows up as /dev/ttyACM0 .... where is it in android?
When I connect an Arduino Uno via USB to my Linux Ubuntu Desktop 14.04, the arduino shows up as /dev/ttyACM0 .... When I connect it via usb to an android phone the device is powered and recognized in Android apps, but I can't seem to find it when i look in a terminal emulator at the /dev folder. When I browse android's directory structure using terminal, where can I find the analogous device?

Further elaboration:
On the desktop I can access the USB arduino device with no trouble, using

screen /dev/ttyACM0

or I can even pipe characters to it directly such as:

echo -n w > /dev/ttyACM0

On the android device, there are no tty* devices in that folder at all.

Someone I know recommended I install a full linux distro on top of android, GNUroot Debian, and maybe it would be there. I did this on both an LG Nexus 5 with android 6.0 as well as a Moto Droid 4 with Android 4.1.2, in hopes that those familiar devices /dev/ttyACM would show up, but they didn't.

Is there any similiar thing to /dev/ttyACM0 in android?

Open html file in Firefox through google drive
I am trying to set up a portable TiddlyWiki ecosystem where I can edit the wiki regardless of where I am/what device I am using.

I would prefer to use Google Drive over DropBox (or similar) because I mainly use GDrive these days and most of the other files related to my wiki is stored on GDrive already.

I must be able to use Firefox since it is able to directly save the wiki. Chrome (or similar) prompts the user to save as or download the file, overwriting the original. This makes it a serious hassle on Android because I do not have physical access to the file in GDrive. Downloading the html, editing it and re-uploading is an unacceptable workflow.

This works fine If I use DropBox. I am able to open with the file, select Firefox, do my thing, and save directly back to Dropbox.

In GDrive, when I open with the file, I do not get an option to use Firefox, only Chrome.

Apart from using Dropbox, is there a solution to my problem? Surely opening up an html file in the browser of your choice should be a doable thing?

Combine duplicate layouts into one layout on Gboard's multilingual support
I have been a SwiftKey user for a long time and for various reasons I am looking to switch to Gboard (one thing is the search feature). However, there is one thing that still keeps me to SwiftKey.

I generally use English, French and Greek layouts. I really enjoy the multilingual layout feature of SwiftKey and I was hoping that Gboard would do it in a similar way. However, this is not the case.

SwiftKey and Gboard both unify EN and FR layouts. However, SwiftKey only really displays one option (fr/en) in contrast with Gboard that displays two options: fr/en and en/fr. I don't know the purpose of this, but it means that I have to change two layouts in order to write Greek, which I don't really like.

How can I trigger an action on one Android device with another Android device?
I recently got a new device and my old device will now be used as a music player with my bluetooth speaker. However, I wanna save battery by not having the old device's bluetooth on the whole time. What's the best way I can trigger an action to turn off bluetooth in my old device using my new device (ie. as I'm heading out)?

I'm guessing there's a way to use Tasker to detect my new phone's location and then toggle bluetooth on the old device accordingly but is there another way that would be less resource intensive? I'm thinking maybe NFC? Like as I walk out of my room I tap my new device to my old device and it turns off the bluetooth and when I get back home the same action reactivates the bluetooth.

Switching app icon background from white back to transparent
I'm using a Xiaomi phone running Android 6.0.1 MMB29M with MIUI global version 8.5.3.0 (MALMIED). A while ago I foolishly tried out some of the themes available by default, then hoped to switch back.

How can I enable app icon transparency again?

Edit: I've looked at

How do vendors flash ROM in Android phones during manufacture?
When Android phones are manufactured, during their factory state they are just an electronic hardware with no piece of software in them. How does a vendor install its stock ROM if those new phones cannot communicate with PC? Is it done through a specialized flash tool which programs the chip for the first time?

Vendor's service centers even recover completely hard bricked Android phone and cost you high price for that. If flashing stock ROM in an empty hardware is so easy for them then why a normal user has to go in so much trouble to treat his hard bricked phone when an easy and free online solution can be provided by the vendor itself.

In my view completely hard bricked phone is equivalent to the newly manufactured device which is yet to be flashed with stock ROM because hard brick loses its ability to boot or enters into recovery mode.

But supersu keeps complaining: "Die SU-Binary muss aktualisiert werden. Fortfahren?" (i.e. super-su binary must be updated. continue?)
If I continue, I can choose between "normal" installation and "using TWRP/CWM" for installation. Neither works.

"Normal installation" yields "SU update unsuccessful" and leaves me a reboot or a link to some tutorials.

"Installation using TWRM TWRP manages to boot directly into TWRM TWRP (yeah!), but does not change anything. super-SU comes up with the same message after reboot.

I also downloaded the last super-SU zip and installed it from TWRM TWRP, but with the same outcome.

I have some suspicions.

the phone might not be rooted properly? I unlocked its bootloader according to the HTC standard process (fastboot and token generation on HTC's website). This at least allowed me to install TWRM TWRP and a modified ROM. I checked root access with two different root checkers and they told me, my phone was properly rooted

supersu is somehow broken?

Galaxy S6 Active stuck at No Command/Downloading
The problem as it stands

My Galaxy S6 Active is stuck in a sort of bootloop, except it never seems to attempt a boot. If it was turning on, without any combination of keys, it would go to the "No Command" screen. From there all I can do is force reset (power + volume down) to get it to restart to the same place or as it displays the Samsung splash screen, press volume up + power + home, it goes to the download screen. From the download screen, I can use my pc to flash a rom (that may not be correct) to the device and according to Odin, that is a success but my device freezes on "erasing".

Imgur album with pictures of the accessible screens

Description of the problem when it was booting

At seemingly random times, the device would freeze and the only way to get it to do anything was to reset it. Sometimes it would enter a bootloop but through key combinations, I would be able to get it out. One time after a bootloop, I had the sense to back up the device's storage, so luckily I have that.

What I've done

I have tried wiping the storage in device recovery -- when it was accessible, I can no longer get to it.

I have tried using Kies/Smart Switch emergency software recovery -- but when provided with the model name and serial number they would both crash.

When the device booted, I tried using the standard recovery feature in Smart Switch. I can't remember the exact message but it was something along the lines of "This device does not support initializing"

I have tried using Odin to flash ROMs (again, I may be using this incorrectly) to the device. I have only tried Samsung release ROMs, meaning ones that have not been modified by a 3rd party. I followed the second and third methods of this guide. Odin never throws an error and it always says it was successful. During the device's initilization with this new ROM, it gets to 32% then goes to "Erasing". A few seconds later the animation freezes. I can leave the device here for hours but nothing happens. So I believe more than the animation is frozen.

I tried using ADB recovery via the device's recovery mode (when it was accessible) but from what I can gather, Samsung uses a proprietary ADB interface that would not work with what I was trying to do (I was following method 3 of the previously mentioned guide (I can't post more than 2 links). I would always get a message saying "ADB server out of date".

I may have done more than that but that's what I can recall.
Any help would be appreciated. Even if you know of a better place to post this, let me know.

Thanks

问:
Question regarding Google Play app compatibility check, x86 vs. ARM architectures, etc
This is more of a hardware question than anything, but it has to do with Android.

I saw on this question, somebody saying that Android apps were architecture independent, and should run on ARM/ARM64/x86 platforms.  Another reply was saying that the APK files can have architecture-dependent libraries, but not code themselves.

Now, here's where my question comes in.

I was looking inside the contents of an APK file, and I noticed that the only "lib" folder was for armeabi (32-bit ARM).  But, my phone has a 64-bit ARM processor (aarch64, with the arm64-v8a instruction set), and the app runs fine.  Hmm... how does that work?

So I thought I would try a few other things.

I installed Android-x86 in a virtual machine, logged into a Google account, and downloaded a few games.  The one in question, which only has the "armeabi" folder, showed up as being compatible (as in, the install button was there) - but it immediately crashed after opening.  I know there are some games that fake-crash on rooted devices (and Android-x86 comes pre-rooted), but the one in question is not one of them.  I've used it on CyanogenMod on a real phone and it doesn't care.

But something else I noticed: at least one other game I was looking for did not show up - the game Super Mario Run from Nintendo.  See my screenshot here:

Notice under "Library" there's no option to install it, and if you look at apps published by Nintendo, it's just not in that list (which means the Play Store is deciding my hardware is incompatible, and basically hiding it).  But, it DID seem to think my Android-x86 VM was compatible with the OTHER games, which just crash immediately.

So I decided to try something else.  I picked up a cheap Intel Atom-based processor (one of the Insignia brand ones at Best Buy, as it's all you can get these days that's carried in stores).  Run CPU-Z on there, you can confirm it's x86 and not ARM.  Super Mario Run shows up, however, and works fine - so do the other games with only "armeabi" libraries!

What piqued my curiosity is that, according to the specifications of the Intel Atom x3 processors, they actually have "ARM" GPUs.  (Specifically the PowerVR 6500 series)
CPU-Z shows this too, where it says the CPU is x86 but the GPU is ARM.  I found some other press releases from 2015, when they introduced the Atom x3 line, about the two being combined.

So in this case, is the tablet only able to run these games because its GPU is ARM? If so, what's the actual significance of the CPU portion being x86? I'm completely confused at that.

I was considering tracking down a used older tablet with an Intel Atom, that still used the "Intel HD Graphics", and was not a hybrid ARM chipset.  Something like a Toshiba Excite Go.  But this is really just to find out if it would act the same as Android-x86, or if those apps would work.  I'm curious what the incompatibilities/crashes are - is it just because Android-x86 is a hackjob and not official? Or do the apps with only "armeabi" libraries truly only work on ARM processors and somehow the Insignia can run them because of its hybrid chip?

(As far as my phone having ARM64, it might have some sort of compatibility layer much like x86-64 for running 64-bit PCs? I don't know much about ARM but I know in the case of AMD64, it's an extension on top of the traditional x86 architecture so you can natively run both x86 and x64 programs - also why they won over Itanium, which was not like this.)

Lastly, as far as the Play store recognizing whether an app is compatible or not - I would assume the developer doesn't have an actual whitelist of all devices the app can run on, that would be incredibly stupid and any time a new Android device came out, it would cause issues.  So how exactly does that work? Do they provide minimum required RAM/CPU/resolution, things like that? Based on architecture as well?  I know I've seen some apps that show as being incompatible with a larger-resolution tablet (like the Samsung View) that do work on phones, and always thought that was strange.

Edit: One of the suggested threads from this one was actually about how the Play Store knows an app is incompatible, based on the app's manifest.  And as much as it might make sense that it would be incompatible if it requires GPS and your device doesn't have GPS, or Bluetooth, etc., that doesn't really explain why an app would install fine on a 7" tablet but not a Samsung View.  That isn't the fastest processor in the world, but it's better than some of the older 7 or 10" ones...

My tab still asks me to sign in to a wifi network which I have been using perfectly well till last months

Nobody else is having the same problem that I have

These are the remedies that I've tried:

Obvious reset of router/phone, I've even restored the router to default and reconfigured it again but still didn't work

Changed wifi setting from dhcp to static but still didn't work.

Cleared cache data but still didn't work.

问:
Android x86 on Hyper-V - The mouse point not following
I installed Android x86 on Hyper-V. I understand there are many difficulties to do this, like the display issue.

But I have to use Hyper-V since my main test environment is hosted on Hyper-V. I need the Android emulator also run on Hyper-V.

I got only one thing not completely solved - The mouse pointer.

The mouse pointer in Android is just not following my real mouse pointer, it is useless in Hyper-V. I noticed it is related to a module, called hid_hyperv. It's considered the HID driver for Hyper-V.

In Hyper-V console mode, I rmmod the hid_hyperv module, and it works fine when I use console directly.

However, if I RDP to the Hyper-V host and use the Hyper-V console, the mouse will not be captured without the "hid" module. Error message:

Mouse not captured in remote desktop session.

I think the cause is still related to the "hid" module, as once I insmod hid-hyperv, the error message won't show again, just that the mouse in Android still not follow my real mouse pointer.

I am frustrated to keep digging, any one has any suggestions or workarounds for this? I don't want to compile a hid_hyperv module for this to resolve it. But if there is some one already did this, I am glad to know. :)

Phone keeps crashing and restarting after rooting
My phone (Samsung Galaxy S6 Edge SM-G925F) keeps crashing, freezing and/or restarting after I rooted it. Previously I also updated the firmware but the problem only rose after rooting it.

Update: I reflashed firmware again after phone shut down by itself and went into a bootloop, phone stayed frozen on the recovery screen for a long time giving me a mini heart attack. Could it be that Knox is making problems, the counter was tripped when I first rooted the phone.

High volume warning, Android
In Android 5.0 and up (from what I've noticed), unplugging a jack device triggers a "volume reset" that lowers the audio output volume. Upon increasing the volume, a toast message appears stating the risk of listening to music at high volumes.

Upon some research, this is as a result of EU regulation. I don't know if this affects US devices, but I would like to know how to prevent the "volume reset" behaviour, as I find it particularly frustrating.

WiFi goes to sleep when device asleep
On my Samsung Galaxy S7, whenever the device goes to sleep, the Wifi goes to sleep as well.

Meaning:

* If I'm connected to a WiFi network and the device is idle for about 10 minutes (tested it), the device won't be connected to the WiFi network anymore (ping is unreachable)

* If entering a WiFi network area and device is idle, it won't connect to the network until I turn on the device manually.

There are exceptions:

* While charging

* When disabling deviceidle option via adb (adb shell dumpsys deviceidle disable), the problem is the option is reset after reboot

What I've checked so far ?

* Different Wifi networks

* All 'Keep WiFi on during sleep' options

* All 'Smart network switch' options

* Setting my router to specific channel and not auto

* Manually disabling almost all possible apps under 'doze' option

* An app to 'keep the device alive'

IMHO, as disabling 'deviceidle' actually fixes the issue (until next reboot), it's some kind of a bug in Android which tries to optimize the WiFi process, but, I hope someone proves me wrong.

Reviving a bricked MediaPad M2 10.0
I own a Huawei MediaPad M2 10.0 (M2-01AL). It was rooted since long.

I wanted to try to install Magisk, so I did it from Magisk Manager. I don't exactly remember what I exactly did, but eventually I screw up the tablet entirely that it entered a boot loop at the Huawei logo.

I just want to reflash it from stock, or something that boots

I have tried several fastboot flashing, but eventually got my hands, thanks to XDA, on what look like official stock firmwares by Huawei. File names:

Huawei_MediaPad%20M2%2010.0%20LTE_Firmware_M2-A01L_V100R001C178B003CUSTC178D001_Android%205.1.1_EMUI%203.1_Finland.rar

These archives contain the magic update.app to be put into SD card and then boot the tablet with all keys pressed.

The firmware flashes the entire contents of the archive into the ROM. However such a flashing stops at around 90% with a generic failure message and request to reboot.

The tablet won't boot.

This is entirely a software problem with the device.

Also tried extracting the .img from the .app with Huawei Extractor and flashing system via fastboot, no result. Phone is still unlocked and FRP is unlocked, as the bootloader reports. I can flash recovery successfully, but I haven't yet found an English TWRP, only luck Chinese and Russian.

Question is: how do I restore this tablet to at least a bootable state? I would like to try this alone before going to a repair shop in my city, there are plenties of it.

Updates

I have successfully installed TWRP in a language I understand. I can see that the system partition is damaged because TWRP, on reboot, says that no OS is installed. This is a first step. I also reflashed stock boot just to make sure, because I found that in order to uninstall Magisk one has to flash the backup Magisk makes. Unfortunately I had no time to fetch that backup, I was too lazy. Anyway I extracted system from the update.app and flashed it via fastboot. No result, the tablet is still in boot loop

Customize on-screen function buttons on Insignia Flex tablet
We just bought an inexpensive, low-end Android Tablet (the Insignia Flex 8") running Android 6.0.  The navigation bar buttons (which are also called, apparently, the "Home Touch buttons", "On-Screen Virtual Buttons", are the default set of three: Back, Home and Overview buttons (the same set shown in What is the offical name of the third on-screen button?).

Now, my LG K7 phone (running 5.1.1) also came with the same default set of buttons, but they are customizable:  by going to Settings > Display > Home touch buttons > Button combination I can choose up to 5 buttons to include in that row.  I can't figure out, though, if there is a comparable setting in the Insignia Flex. Is there a way to customize those buttons?

The device, by the way, is not rooted, and I prefer to keep it that way.  I am looking for a way to do this using only the built-in features of the device.

How to dump Android's external SDcard that is used as internal memory?
although StackExchange sites have helped me a lot in the past, it's now the first time to actively post a question here.

I have an issue with my Motorola Moto G which is running with Android 7.1.1 (Lineage OS) - I was searching throughout the whole Internet but w/o success.

I want to do some forensic work on the memory of this device. It has an internal flash, and an external SDcard, which is formatted in a way to extend the internal memory as well. I think, since Android Marshmallow there is this option to do that.

I can dump the internal userdata partition and mount on my Linux PC w/o problems:

```<code># ADB Shell:
-> ls -l /dev/block/platform/msm_sdcc.1/by-name/
      ... userdata -> /dev/block/mmcblk0p42
# Host PC:
-> adb pull /dev/block/mmcblk0p42 mmcblk0p42.img
-> sudo mount -o loop mmcblk0p42.img mmcblk0p42
-> ls mmcblk0p42
       adb app-ephemeral backup ...
</code>```

I am trying the same with the external SD-Card formatted as internal:

```<code># ADB Shell:
-> ls -la /dev/block/platform/soc.0/7864900.sdhci/by-name/
      ... android_expand -> /dev/block/mmcblk1p2
# Host PC:
-> adb pull /dev/block/mmcblk1p2  mmcblk1p2.img
-> sudo mount -o loop mmcblk1p2.img mmcblk1p2
       mount: wrong fs type, bad option, bad superblock on /dev/loop1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so.
</code>```

What is wrong here? If I put the SDcard to a card reader then the partition are recognized but cannot be mounted due to unknown file system.

Any help is very appreciated. Jens


问:
Bug in text selection on Android O?
Nexus 6P, Android O (8.0.0), not rooted.

When I long-press (or double-tap) a word in a textarea field, often the result is that much more than the targeted word is selected. Roughly two lines of text may end up selected. Obviously this makes text selection more difficult, because then I have to use the handles on the selection to resize it to just the word I wanted.

This doesn't occur every time, and I'm having a hard time understanding why/when it does or doesn't occur.

I normally use Swype as my keyboard, but I tried switching to GBoard and saw the same behavior, so I don't think it's related to the keyboard.

I've seen this behavior in Twitter, Fenix (third-party Twitter app) and Google Keep (maybe other apps but I don't remember). But like I said: not always.

I've never had this problem before Android O.

Has anybody observed such a behavior? Is there any known fix for it?

One thing I'm beginning to note as I write this post: this problem doesn't seem to occur if the text is in English; only if the text is in French. It seems a little weird but it's the only criteria that I'm able to discern for now. (I use both languages frequently; I have Android itself set to English.)

Example (screenshot below): long-pressing any word after "montre" (first line) results in this exact selection. Long pressing any word before (and including) "montre" gives the normal result (only one word selected). (In case you're wondering, the selected text has absolutely nothing to do with Google Maps.)

UPDATE

No solution found yet, but in case it helps somebody, I noticed that once this larger selection is set, you can tap a third time on the word you want to select, and then the selection will be reduced to this word. So the problem is not as bad as I first thought. No need to use the selection handles, you just have to tap three times instead of two.

Android Nougat 7.0 Wifi Internet Drops after ~10MB

First a bit of background

Bare with me as all of below should be relevant.

I currently have a HTC 10, so does my father. My phone I bought from eBay and it came with the Nougat (7.0) update already installed (lets call it phone 1). My dads phone came directly from HTC with Marshmallow installed (phone 2). Both devices are the same factory unlocked EMEA version of the phone.

On "phone 1" I had no Wi-Fi issues, and initially neither did "phone 2". Shortly after purchase we updated "phone 2" using OTA updates to the same version of Nougat (7.0) as I have (it had the same HTC version number). This started causing Wi-Fi problems on "phone 2". Because it became a problem only after the update, that rules out a hardware issue. Furthermore because "phone 1" didn't have the issue I can rule out the Wi-Fi router as the cause.

HTC released a new OTA update for 7.0 with the July security patches. I updated "phone 1" using this OTA and suddenly I have the same Wi-Fi issue as on "phone 2". I tried to no avail wiping the cache partition and also going to the extreme of doing a full factory reset. The problem remains on both phones.

Debugging

After some playing around with various Wi-Fi settings on the phone (static IP, disabling battery optimisation, disabling mobile data), I the issue remained.

We then tried to do the OTA update on "phone 2" and it revealed some interesting information. During the download it would happily download roughly 10MB of data (sometimes 7MB, sometimes 10MB, once it jumped 30MB). After this the Wi-Fi would remain connected, however the phone could no longer contact the internet. If I turn the Wi-Fi off and on again, it will download another ~10MB and then no internet again. Repeat ad infinitum.

I tried to download a couple of apps from Google Play on "phone 1" and noticed the problem is the same - it downloads ~10MB then no internet. Turning the Wi-Fi off and on again, another ~10MB.

I saw on Reddit (here) that entering into the phone app the number *#*#4636#*#* loads some testing phone settings. Looking at the Wi-Fi status in that I can see that the phone connects to the internet after turning on the Wi-Fi by running the ping test which passes. After downloading a chunk of data over Wi-Fi, the ping test fails stating "unknown" as a result, then shortly afterwards changing to "Fail: Host unreachable". This shows the internet connection was for some reason lost, however the Wi-Fi status still shows that the network state is still "Connected to SSID".

Question

Is there a solution to this issue?

It's an odd problem that seems to be very repeatable, but I can't seem to find any settings that fix the problem.

View all app ratings/reviews in one place irrespective of language
I have been using Google Play and Google Play Developer Console for monitoring the status and ratings/reviews for my apps on Google Play.

One thing I have observed is that, we can only view some the ratings and reviews in our current locale (language) on the Developer Console. If a user rates my app, say in Spanish or Portuguese, I am not able to see that rating anywhere (neither on Google Play nor on the developer console). Only, if such a person also writes a review, would I be able to see it on the Developer console.

One way out of this, is to individually append the hl-(locale code) say, hl-es or hl-fr on the URL of the page on Google Play. But this is tedious as I have to guess which locale the current user who just rated my app (and didn't put a review) is from.

I can also download the ratings from the console in .csv format, but this is never up-to-date.

On desktop PC, there are great apps / Chrome addons such as Gorgias that allows to write abc <TAB> and this will be automatically expanded into a long text, thus saving many keypresses.

On Android, there is Texpand app that does mostly this, by using accessibility features of Android.

Problem: it works when writing a SMS, but this doesn't work in text fields on web pages (for example in Chrome, while using gmail.com). (the Texpand FAQ item 3 says it doesn't work and I can confirm).

Sadly this is exactly where such an add on would be the most useful: to write emails faster on phone.

Question: how to have text expansion on Android in Gmail?

Using an Android phone to pass through a dial-up modem signal
I have a Samsung Galaxy A5 (2016) and an old laptop with a built-in dial up modem.

I would like to know if there is any way to connect the modem to my mobile and use it to pass through the modem signal (as if it was just connected to a normal wall socket). I assume there would have to be some sort of special cable, but I've done some googling and there only seems to be suggestions on how to turn the phone into a modem itself instead of just passing through a signal. Is there any way that this is possible?


问:
Give app resource priority?
I have a couple apps I use regularly that take a lot of resources, the biggest hog is Vainglory which being essentially a desktop-class game uses most of the ram, CPU power and network bandwidth my Galaxy S5 has to offer when running.

It works fine most of the time, but occasionally while I am playing, the operating system or other apps will start doing things in the background causing my framerate and ping to drop dramatically.  Also when the app looses focus, even for just a second, it has to reload completely due to the large amount of memory it requires.

Is there a way to tell Andriod to give high resource priority to particular apps and prevent other applications and processes from working in the background while those apps are running?

Moto G Play gets wako. Speaker fault. How to find source of problem?
Every 24-48 hours my Moto G Play / Android 6.0.1 gets wako meaning:

(most often) During call I can't hear the other person and other person can't hear me,

(rare) Notification sounds are played very quietly (nearly silently) even though sounds volume is set to maximum and other tones (i.e. ringtones) are played correctly.

Things that I'm sure:

restarting phone always solves above problems,

if phone gets wako, problem always narrows to speaker / microphone; all other functionalities (SMS messaging, emails, Internet browsing, playing games, using apps) works normally,

these situations happens only on my phone; my wife has exactly the same model with exactly the same Android version and nearly exactly the same applications set and hasn't noticed this behavior so far.

Things that I'm uncertain:

if I'm not mistaken described problems occurs only if phone isn't used very often -- i.e. if there was 6-8+ hours since last call made or received; if I'm calling often, phone doesn't get wako.

How can I check or what can I do to check, if this is software (Android), network (LTE operator) or hardware (Lenovo) problem? What tests or operations should I perform?

I could say (given that wife's phone has absolutely no problems) that this is certainly hardware problem. But then, restarting phone always solves problem, so this would indicate Android / software problem.

Play Store crashes when trying to open "Manage Instant Apps"
Well, it's not like I want to use instant apps but this is frustrating me either way. When I open Play Store and go to Settings and try to open "Manage Instant Apps", the Play Store just crashes and starts again with a message.

I'm on stock Marshmallow, Play Services for Instant Apps version is 1.19.

Here is the log when it comes to crashing:

Flash zips in download mode
I have an old Galaxy Ace II with no installed ROM and stock recovery, and I am trying to put a custom recovery/ROM on it but all I can find is flashable zips intended for flashing in recovery. I cannot transfer them to the phone as adb reports the filesystem as read-only (adb shell tells me the shell doesn't exist).

I don't know whether what I'm trying to do is possible, I don't know if I'm being stupid, but is there a way of transferring or flashing the zips in download mode using Odin/Heimdall, or is it possible of transferring the files to the phone any other way?

EDIT: Recovery download

问:
Get around Exchange screen lock policy
I am accessing my company's email via Exchange. I'm running Android 6.0. The Exchange Policy sets the screen lock as soon as the screen timed out (immediate). Even though the timeout is set to 10 min, when I press the power button, it is considered screen timeout and I have to unlock. (power button instant lock is NOT checked).

I like to turn screen off whenever I am not using the phone to save battery. I found it very inconvenient to enter unlock code even after a short screen off. Is there a way around that?

Restore single app from Google backup
I have two devices that both have automatic backups enabled through settings. I see both backups on Google drive.

The settings have an "auto restore" option, which implies there's most be a non-auto way to restore, but I can't find it. (Not that I managed to decipher how auto restore works).

So how can I restore the app data from it's backup, and,
Can I restore the app of 1 device to the backup of the other?
