Android MultiUser: show notification for all users
I have an LG Nexus 5 with Android 6.0.1, the device is rooted and with XPosed installed (if this can be useful to the question).

I have 2 different Android users, one is personal and one is for work. I'm using 2 different accounts instead of Android for Work because I care of keeping the data of the 2 accounts divided at max as possible.

The only (the very only) problem is that I do not receive notifications from an user until I switch it back to it. Is there a configuration, an app, a root procedure, even an XPosed module which can bring the notifications from the 2 accounts togheter?

Ghost touch problem with my Lenovo A3300?
It seems to be happening randomly. There are times where I can use it without any problems occurring and there are times where I can't even scroll properly due to that one spot of the screen getting spammed with random touches. It's honestly driving me nuts!

I know which place the ghost touches are happening as I've turned on the "Show Touches" option in the settings but how can I fix it? Does the screen need to be replaced or something?

问:
Can I adjust the graphics memory allocation on my phone?
My current phone is advertised as having 3GB of RAM. Under Settings/Memory Total Memory is listed as 2.8GB.

I recently saw a newer phone with a more modern System-On-a-Chip with 4GB of RAM. Total Memory showed as 3.5GB.

From reading around I believe the difference is down to the memory being set aside for graphics (or perhaps peripheral addressing at a guess, failing that).

If the former, as the screen resolution is the same (1920x1080) and I never had a problem with graphics on the old phone with 200MB set aside, is this something that can be varied, perhaps in a custom ROM, for instance Lineage, or would it be be buried too deep in hardware drivers?


问:
stop WhatsApp duplicating images sent with the camera
At least on my device (Galaxy S6) whenever I send a picture or video on WhatsApp using the camera, the following happens:

A low quality version is stored under WhatsApp/Media/WhatsApp Images/Sent

A higher resolution version is stored in WhatsApp/Media/WhatsApp Images

The same happens with videos under WhatsApp/Media/WhatsApp Video.

In some cases as well, sending pictures from another media source puts them all in "/WhatsApp Images" rather than on the Sent folder.

Every now and then I like to move all the media to my pc/back it up online, sort it on folders etc, which becomes a real pain due to this fact. I.e I want to keep the higher res. versions, then I must first identify them from the "received" folder (for things I send.. why not put them in /Sent??) then delete the low res. versions.

With already a few years on the market and its value you'd expect an app of this magnitude to have a significant team of developers behind, then it's almost unbelievable that such a mess is created by this app.

Am I missing something here, some issue with my device/settings, or does the app just suck at this?

问:
Possibly Soft-Bricked Droid Razr M
I'm currently in possession of a Droid Razr M that may be "soft-bricked". It's bootscreen won't progress beyond the red Motorola logo. I can't turn it off unless I do it via soft rebooting, in which case it just reboots and gets stuck at the logo again. I've already done a hard (factory) reset, which I assume succeeded. The device never had its bootloader unlocked, nor was it rooted. It did receive all available OS updates available for it (it only went up to some version of KitKat). This is also not a developer edition.

At this point, what I want to know is: can the device have its bootloader unlocked or be rooted in any way? If not, is there anything I can do to restore this device to some kind of working order? I'm unsure as to where I would get appropriate stock images for the device (it had a Verizon-customized Android installed on it), so I was planning on flashing something like LineageOS. If there is nothing I can do for the device at this point, I'd like to know so I can avoid wasting time on it. Thanks for any assistance in advance.

Installed TWRP recovery on a Verizon-locked device but didn't unlock bootloader: options?
On a Verizon Galaxy S3, I installed the TWRP recovery not realizing Verizon's bootloader is locked. Now it boots to "System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help."

Short of actually going to the Verizon store and begging them to recover this phone, what are my options for recovering from this mess? I imagine if I could just rewrite the original recovery then I could use an easy unlocker app inside the OS. I did back that up before installing TWRP so there's that.

Worth noting: through some combination of buttons I did once get this to boot into Odin(?). It said it was downloading something but never seemed to finish. Not sure if that's helpful.

问:
Why do some apps allow me to play sounds along other apps, and some apps don't, and can I control this?
The user: I like to play both white noise, such as brown noise or rainfall or other ambient sounds, at the same time as low key ambient music. It helps me concentrate when I work.

The goal: I want to play music from one app, such as Digitally Imported Radio while I simultaneously play brown noise with an app like Chroma Doze.

The problem: The apps take control of sound output exclusively of each other, so that when I play one, the other stops playing.

Almost solutions: I found one app, called Simply Noise, that will play alongside other apps. However, it is not very well developed or maintained. It can't be turned off unless you go to the Application Manager in settings and force close it. At least it partially does the job, though. Most apps, won't play alongside other apps using sound, and some can't be used in the background at all.

The ideal: The best thing would be to find a white noise generator app that is full featured and lets me play alongside my music apps, as well as letting me set volumes independently of each other. Chroma Doze has the nice feature of letting me play with various EQ levels so that I can tweak my perfect noise.

Another option: Is there such a thing as an app that will allow me to mix sound from other apps, so that I can run them simultaneously and control their volumes independently? I looked for that kind of app, but only came up with apps like App Volume Control Pro, which seems to allow me independent volume setting, but does nothing to allow for simultaneous playback.

The Question: Why is it that sound apps are all over the map when it comes to playback? Some allow simultaneous playback, some don't, some have independent volume control, some force you to use the system volume, some won't play in the background, some will... Are there any options to help me play two apps at once, with independent volume control?


问:
android "insta apps" updating without permission
Happened to open my android Marshmallow based screen on my unrooted phone.  Saw a message that "insta apps" was updating.  Download completed before I could stop it and update history does not show this package as being updated.

I have:

verified that there is no package installed in the settings->apps list with insta apps in it's name.

verified that install from 3rd party source is turned off in my settings->security options

made sure that my play store settings for auto-update apps is set to do not auto-update apps.

did an adb backup and had a look at the package list and did not find any apps with insta in their package name.

I did download a audio recorder application from the play store which kept flashing dodgy messages.  Maybe it installed something else?

Anyway to track down what this is?  My phone is not rooted but I do have dev studio access to it.  Maybe it's time to put the phone in the wood chiper and never use the playstore again?


问:
Is it possible to find and recover a Word for Android document?
I have an Acer Iconia B1-A71 which I bought about a year ago, if I remember right. It has Microsoft Word for Android pre-installed. In my naivety I assumed it was a free no-strings-attached app.

Today I was taking a train trip, 2 hours each way, and I thought I'd try using it to work on a fairly large Word document. I sent it to myself via email. Clicking on the .docx attachment started the Word app. It went though an initialization process, but I am very sure that it did not warn me that by using the app I would have to sign up for a Microsoft account and provide permission for Microsoft to access my contacts.

I spent about three hours working on the document during the trip.

When I got home I tried to "share" it by sending it to myself again. What I got was the original unmodified document. Then I tried to "Save as" on the device, and the app crashed or went into a loop, spinning the circular arrow and saying "Working on it". After 4-5 minutes I killed the app.

Now when I start the Word app it demands that I sign up for a free account, and share my contacts with Microsoft. This I refuse to do on principle.

Where I come from this kind of thing is called "bait and switch".

So my question is, is there any way I can find and recover the edited .docx file using File Manager or something (I have tried to find the edited document but can only find the original one), or do I accept that Microsoft has cheated me out of three hours of my time?

ARM big.LITTLE effectiveness in custom roms
In stock roms it's obvious that the manufacturer tries to make use of big.LITTLE technology as mush as it can (cluster managing, workload distribution etc.); I'm wandering what will happen to "these under the hood optimizations" when we install a custom rom on the phone?

问:
Dimming service still works after app uninstall
I have installed a sleep monitoring app (Sleep as Android) on my LG G3.

It has a feature that dims the screen when the monitoring starts.

It was very annoying, so I disabled it in the settings of the app.

In the mornings I stopped the monitoring and resumed using my phone.

For a few days now, in normal usage (even if I read emails, or even play games!), my screen dims until it becomes dark grey (it is not locked) and I can't undim it, just lock and unlock.

I stopped the application but the dimming kept happening.

So ultimately, I uninstalled the app.

The dimming still happens, so I presume the app had some service installed that makes the screen dim.

When my phone tries to lock itself (after 2 minutes of idle screen time), the dimming wakes it up and they fight! You can see how it looks:

Can I somehow uninstall the dimming service?

Problems in copying files on Android 6
I use a Huawei p9 with Android 6. I notice a big problem. When I connect the phone with a Lubuntu pc trying to share files, I get e.g. that for copying 7 folders - each containing several small files for constructing html's pages - from pc to phone they are required about 10 minutes, when the total size of the folders is just 30MB!

On the other hand, when I perform the same action e.g. using instead 3 multimedia files of the same total size (i.e. 30MB), the amount of time is just 1 second (as indeed I expect).

Can someone explain why do I verify such an exaggerate discrepancy in time between the two mentioned cases? I think it may depend on the Android system (potentially by the emui p9 redesign -- otherwise every Android 6 device should have this problem!).

I  finally notice that with a more dated device mounting Android 4.2, I don't encounter that inconvenience.

Is there a time limit for downloading/installing a large app?
I have a Shield Android TV (first version with 5.2 installed).  I'm trying to install Half Life 2: episode one from the play store.  But it's not working properly.

The app is 2.6GB and over DSL it's going to take a while.  I'm not getting any errors, but after a while (something more than 50 minutes) when I check I find the install has stopped and I'm back at an "install" prompt with no indication of any saved progress.  Selecting install just starts the process from the beginning again.

As this is a paid app, I doubt I have the option to just download an APK via a different tool and sideload.

Is this a timeout on the system?  Any workarounds likely (short of a faster network)?

On earlier attempts, when I cleared the screensaver, there was no message.  On my most recent try, I kept the screensaver off and around (exactly?) an hour into the download an error appeared.

How can I make sure apps that are moved to the SD card stay there?
I'm using a Samsung Galaxy S4 (GT-I9505, Android 5.0.1, not rooted). Have 16GB total internal storage, and a 32GB SD card - the internal storage always seems to fill up quite quickly (not least because of the 7GB used as a base by the system) so I prefer to keep as many apps as possible on the SD card instead of the internal storage.

The problem that I have is that, if I move an app across to the SD card via the application manager, it seems to only stay there only until the next time an update's installed via Google Play. Something about the installation procedure seems to bring the entire app back to the internal storage (by which I mean, the "SD card app" becomes 0B; however, it does appear to leave the "SD card data" intact), which means that I then have to laboriously go through the process of transferring everything back to the card one-by-one -- obviously less than ideal.

Is there any way I can tell the app manager and/or Google Play  to "move to SD card and keep it there"?

How to Destroy Android Phone permanently
I recently found an old Android phone in my drawer, which I would like to destroy permanently.

What I mean by that is:

I want to completely and irrecoverably wipe/erase absolutely everything.

Not just the free space, not just the data partition. Everything. The system partition, the firmware, every single byte of the phone's storage. Absolutely everything. The entire storage chip. I do not plan on using this phone ever again or selling it. I will also physically destroy this phone afterwards, however first I want to ensure that all data is permanently gone.

Is there any ADB or terminal command I can use to accomplish this?
Again, keep in mind that I do not care if the phone becomes unusable after doing all this, because that's exactly what I want to achieve.

On my Linux machine, I'd just run a command such as "dd if=/dev/zero of=/dev/sda" and it would erase every single byte of storage. Is there any equivalent like this for an Android phone, perhaps?

Thank you very much.

问:
Save and hide notifications and then show them later
Is there any way I could hide notifications from certain apps entire, but then have them appear later at some specific time or event? Essentially, I'd like to contextually delay notifications intentionally.

I know there are plenty of apps that can log notifications, or even roll them up into a single notification. Theses are very close to what I want, except I don't want the notifications to be intercepted at all times, and I don't even want to see that notifications have been blocked until some predetermined time or I check on them myself.

I'm pretty sure I'd have to hack together a solution, maybe using Tasker to prevent some of these apps from working and hiding the notifications from these notification loggers.

I'm on a stock, unrooted Galaxy S8 (Android 7.0).

Hide birthdays from MS Activesync calendar
I've a Samsung Galaxy A5 (2016) with Android 6.0.1

I've added recently my Microsoft Live account to it as MS ActiveSync to be able to synchronize calendar (Samsung S-Planner).

The calendar is synchronized correctly, however I can't hide birthdays and national holidays.

I want to see only my appointments, and not all those community ones.

For other accounts on my phone I can control synchronization for events / birthdays / Contacts ..., however for live account there are only "Calendar" and "Task" options.

Everything is categorized under "Calendar" if it's on I see everything, otherwise nothing.

(in web access, or MS Outlook on pc I can hide birthdays and holidays correctly).

I've searched the web for a solution, however the advice for similar situations was always to go to settings and hide holidays, which option I don't have.

Using TASKER to automatically change launcher/theme when launcher/theme is changed by other program
I am using a Huawei P9+ running on Android 7 (Nougat) and one of the annoying things with it is from time to time, the theme reverts back to the ugly Huawei Home theme, even though I use Nova Launcher by default.

Right now my strategy is I manually go to Apps -> Default App Settings -> Launcher to change it to Nova Launcher, however from time to time it would revert back again randomly.

I have Tasker installed and I am wondering if there is some way I can configure it so that whenever the launcher is changed to something other than Nova Launcher, it would be able to switch back to Nove Launcher automatically?

Forgot to mention I have Secure Settings (paid version) installed and my phone is rooted (using Super User, there is no proper SuperSu that works on this one yet).

How to improve visibility of Android Nougat quick setting tiles?
Android Nougat introduces Quick Setting tiles that are available from pulling down the status bar on the top of the screen.

Unfortunately, on many devices, the tiles are light gray icons on a white background, which makes them very hard to see.

Furthermore, when they are enabled, the icons switch to cyan on white.  This makes differentiating between the on and off states challenging in good lighting, and nearly impossible in bright light.

For non-rooted devices, how can the quick setting tiles be changed to use a dark background, or at least, implement a higher contrast?

问:
Difference between "unmonitored apps" and mDeviceIdleWhitelist
I've got a Galaxy S8 and have come across an interesting situation. Now, either something strange is going on, or I've got no clue how it actually works!

I've downloaded an FTP Server app on my phone which I wanted to leave running in the background. The problem was that, once the screen turned off, the wifi connection would drop after 5 mins and I couldn't connect to my phone.

I had enabled the setting for WiFi to always be connected and I know that the app has both PARTIAL_WAKE_LOCK and WifiLocks so I had expected the connection to remain in place.

I added the app to the list of "Unmonitored Apps" in the battery optimisation settings but this had no effect.

Using adb I could see that the UID of the service holding the WAKE_LOCK was not listed in mDeviceIdleWhitelist so I ran adb shell dumpsys deviceidle whitelist +PACKAGE_NAME and saw that the UID was now in the list.

After running this command, the app behaves as expected and I can continue to connect once the screen has been off for a while.

So my question is whether there is a difference between "Unmonitored Apps" and the mDeviceIdleWhitelist? If there isn't, is this a bug in the phone software?

问:
What permissions I shouldn't block with my Privacy Guard?
I have installed LineageOS with "stock" version of Open GApps. I noticed Privacy Guard can control which apps have access to which information. I have changed nearly every permission to "ask me" and my system refused to cooperate (was freezing immediately after booting, see similar problem).

Therefore, there must be a critical set of permissions that must be enabled (in Privacy Guard) in order for the system to work properly. What are those permissions?

I am using LineageOS v14.1 (Android 7.1.2).

Note: I do not want to troubleshoot my problem. I need an answer saying "if you block this information for that app or that information for that app your system will stop working". I have solved my problem by flashing the phone again, so I'm safe.

Recent apps list repopulates on Samsung S7 (Nougat)
I've got a question for the experts here. I've recently begun clearing my recently used apps list before bed. When I awake, I check it to find that a bunch of apps that have popped into the list - some apps that I haven't used recently at all (if ever?), let alone obviously not used during the night. This is happening even after clearing the apps and a reboot of the phone.

Any idea why this could be happening? Is this a feature? A bug? A hack?

ps - this happens during the day as well. After a period of inactivity in my pocket, there might be a few new random apps in the list. They range from config apps to messages to anything really. I have PIN lock enabled and lock-screen notifications disabled.

问:
How to access google drive app backup data manually?
Since there is no way to restore app data from google drive's automatic backup outside of first setup (which has come and gone), is there a way to manually access and download the files for manual restoration via root/recovery?

Background: I migrated phones and backed up via adb backup (did not have root).  Unfortunately, many apps disable backing up of data through that method.  Curiously, some of these apps actually use Android's google drive backup.  Most notably whatever version of GMail I had on my phone.  After a day of restoring adb backup and setting up my phone, I realized that GMail's and other apps data was not recovered.

Using google drive, I can see that data exists when managing backups and selecting my old phone.  How can I download it or access the raw data on my google drive?

The plan would be to use TWRP that I have to put the files in the /data partition.

For the curious, GMail is a pain to configure because I use a large array of filters move mail into various tags, making them act like folders.  To see any of that mail, I have to manually click through each tag and synchronize+notify, even though the ones I want to sync are nicely categorized under one encompassing higher priority tag.  Of course one day I'm sure they'll make it easier to configure.

Red State.

But it does not boot. The screen simply goes black, and reboots to the same screen.

I can enter the "meta mode", but I don't know what use that is, because neither in the normal mode nor in the meta mode the phone recognized by adb or fastboot.
Linux still recognizes the phone a some sort of USB device, though:

usb 3-3: USB disconnect, device number 3
```

Pressing volume down + power button does nothing.
The phone simply remains off.
If I keep pressing the power button a long time the phone vibrates, but still does not boot.

I have no I idea what I can do. Did I brick my Moto M?

I don't really care anymore about custom ROMs or stock ROMs, I simply want my phone to work again at all. :(

问:
Why doesn't Motorola Moto G4 sometimes not accept phone calls?
I'm using a Motorola Moto G4 Play with LineageOS. From time to time I get a message that someone tried to call me, but I wasn't available. This hasn't happened with other phones, so I suspect that it is some bug/bad behaviour.

From what I can tell this usually happens when the phone is locked. However at least once it happened when I was using the phone. The phone itself is not in "Do not disturb" mode. But I try to disable it (although it is disabled) my impression is that phone calls come through. As far as I can tell the phone always has radio reception. So I'm out of ideas what can cause this behaviour.

How can I debug this behaviour or do know what can cause this behaviour?


问:
Bug or feature? Android ignores DNS servers with IPv6 ULAs when in an isolated ULA network?
This has cost me some hours of finally tracking it down, but I would like to know if someone can please shed light on this issue?

Android 6 and 7 do not accept DNS servers with IPv6 ULA addresses. Using some diagnosis apps, I can see that Android does in fact learn the DNS server addresses from router advertisements. But after some seconds, Android deletes them. But it keeps any SLAACed ULAs. Unfortunately, without DNS, these devices are pretty much useless in IPv6 networks with ULAs.
(But see note below.)

In contrast, when using GUAs for the DNS server address, Android 6 happily learns and uses them.

Any reason why Android dislikes DNS servers with ULAs and only accepts "real" global addresses? Seems to take the meaning of "globalization" to a new level... ;)

Update 2: Android 7 in general does not accept ULAs, but instead considers such a network as not working and won't connect to it (tested with an Ethernet-wired Samsung Tab S7 running Android 7.0).
Update: Android 6.x actually can accept DNS server ULAs, but I'm seeing this only when the network interface not only has an ULA, but also a GUA assigned. No GUA, then DNS server ULA get rejected. Now that is strange. I've updated the title to reflect this finding.

How to identify which app is reading from my disk
Except for disabling one app at a time or all at once and then enable them all slowly again (The Elimination method) - How do I identify what app is reading my disk ?

Is there a way of switching this off? I have scoured the menus / preferences and can't find a way of doing this. The next step ... ICS source code :-/

How to debug bootloop?
I built custom Cyanogenmod 13.0 for Galaxy S5 Exynos (G900H), however after I flash my ROM, the phone is stuck on bootloop with the Samsung logo turning off and on in a loop.

since CM and LineageOS does not support my specific S5 model (G900H) - I added the missing folders (device, kernel, hardware etc.) from fevax's repositories (https://github.com/Fevax).

After fixing some compile errors and adding all of the needed fevax's repositories, I successfully built a CM ROM zip file using the 'brunch k3gxx' command.

However, as I said, flashing it (after factorty reset) using TWRP recovery goes into bootloop. I also tried flashing only recovery/boot/system partitions using heimdall but it also leads to bootloop.

I thought that maybe the problem was the toolchain but after a long research I found out that it was probably ok (prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi-).

In addition, fevax has published his own ROM for this exact model and I flashed it successfully and it works fine. I tried to contact him (Email, xda messages etc.) but he didn't answer me yet. I want to make my own custom ROM, so his ROM only proves that it is possile to create a custom CM ROM for this special S5 model.

Currently I have no idea how to even understand what causes the bootloop, the 'brunch k3gxx' log does not show any unusual warnings or errors.

So, is there any way to debug a bootloop in Samsung Galaxy S5? Or any other way to get information about why that bootloop occures?

He's dead, Jim! -- Phone is bricked, how screwed am I?
This morning started with a catch-up, as always. I clicked a YouTube video, and the phone crashed. Just instantly crashed to the HTC logo screen, like it was rebooting.

It crashed again. And again. And again and again and again...

Eventually, it gave up.

It is so crashed, that plugging in the charger doesn't even light up the "charging" indicator light. Plugging it in to my PC causes it to identify as "Qualcomm HS-USB QDLoader 9008 (COM4)", which is about as far as "HTC 10" as you can get.

Considering I just last night achieved the highest level in a game I was playing, I'm somewhat more frustrated about this than normal.

What are my options, if any, for data recovery - bearing in mind it's encrypted (I enter my unlock pattern when I boot it normally)?

In one mail account the sent messages got stuck. They are in the Outbox folder marked as "Queued". Every now and they they change to "Sending" and then back to "Queued". The other accounts (different servers) work fine. The server type is IMAP+SMTP. The outgoing server settings are identical to settings used on a laptop (Thunderbird app) where they work fine. The laptop and phone are in the same WLAN.

Bluetooth connection fakeout
I have a Nexus 6 running Nougat. I've always had it connected to my car speakers via Bluetooth. Last night, I hit play on my music app, and although the car's display screen showed the song info and the progress timer, and I was able to navigate through my playlist (i.e. the car thought it was playing), the sound came from the phone.

I thought it was an issue with the car's connection, but then today I tried to connect my bluetooth earbuds, which have worked fine in the past. The phone's bluetooth settings showed that the earbuds were paired, and the buds gave me the little beep tone to indicate pairing, but again, when I hit play, the sound came blasting out the phone speaker, rather than through the earbuds.

I've tried unpairing and setting up from scratch, and that doesn't seem to make a difference. Any ideas?

Signal, WhatsApp, etc. without Gapps on Copperhead
There is seemingly no way to install gapps on Copperhead OS anymore, as indicated by the Copperhead OS bugtracker.  Yet, Mike Perry does it by installing Copperhead piecemeal.  What is going on here?  What in Copperhead OS's unified install breaks gapps?  Is it just the android-info.txt file in the image zip?

As an aside, I only wanted to install Google Play Services because it sounded like Signal, WhatsApp, and maybe Wire might not receive messages in the background without gapps pico installed.  Signal warns about this, and asks to burn oodls of battery to fix it, but I do not know if this really matters.  I do know microG cannot be used to fix it currently because the way microG spoofs Google Play Services breaks security throughout the phone.


问:
Use Android as an AVRCP client, not server
I paired via bluetooth my phone (Moto G5, Android M stock non rooted) to a linux box, and among the services that it advertises I found out that the phone can act as an AVRCP remote (that is, send play/pause requests etc just like a bluetooth headset with buttons would do). In linux (which uses the BlueZ stack) this is automatically handled by creating a virtual keyboard that can generate events such as volume up and whatnot, so the receiving side is working. However, I cannot find a way to actually send these commands from the phone. Using the bluetooth volume slider doesn't seem to do it (it must be a knob of the software mixer on the phone).

Is an app necessary to use this functionality, even though the service is always advertised by the phone? If so, which one?

Apps abruptly close and/or keyboard minimizes while using Gboard (6.0 & 7.1)
Ever since purchasing this OnePlus3t brand new with 6.0.1 installed, the pre-installed Gboard I've been trying to type on abruptly minimizes, sometimes closing the app with it.

I haven't hooked it up to adb/ddms yet but I was wondering if there are any known issues with Gboard, OxygenOS or perhapse the OnePlus3t hardware in general.

Though this behavior occurs mostly in Messages, the proprietary Messenger (like every time I use it), it does also happen in Chrome and Jota. Interestingly it only occurs "the first time" the keyboard's been used in a while. After that first "crash", it works absolutely fine. Once the phone has been idle/asleep/un-used (di.fm is usually streaming) for a "while", it happens all over again, severely burning my marshmallows (apples are probably healthier and not so sickening sweet, i just don't want to turn into an iFruit).

The recent 4.1.6/7.1.1 patch installed recently didn't resolve the issue either.

This device is for all intents an purposes completely stock. It hasn't been rooted, loaded with a custom launcher, or any other potentially problematic software (I've got a few main stream apps like Jota, di.fm, terminal (installed recently), ...).

I tried turning off some text-prediction features in the Gboard settings to no avail.

installing gapps without custom recovery
i have a SM-J7008 which was recently flashed but has no google apps installed. i read it was possible to in stall them using busybox. i would like a little more detail with the method mentioned here:

If you want to install without modifying /system then it's impossible.
  So the answer is "No, you can't" with neither root access nor recovery
  flashing. But if you simply wany to DIY without using a custom
  recovery, it's OK. Takine OpenGApps as example. Download their ZIP and
  extract it.

```<code>Install BusyBox
Use busybox lunzip to extract the .tar.lz files in Core/
Move files other than APKs to /system. You will find things to be merges into etc/ and framework/. Take care of file mode (permissions)
</code>```

and owner/group.
      Install GoogleServicesFramework.apk as system app. In my experiments it sometimes fail if not installed as system app.
      Install the rest of the APKs as normal.

You can't install GApps without modifying /system. As you see, there
  are quite a few configuration files that will be merged into
  /system/etc during installation, and a few essential framework JARs to
  be installed to '/system/framework. They won't work if installed
  elsewhere.

HTC 10 Multiple Wallpapers
I've recently got an HTC 10 which is running Android 7.0 and is set up to have 5 pages on the home screen with the HTC sense clock/weather widget on the central page (which is set as the default page).

I was looking for a way to set the home screen wallpaper to have a different image on each page - actually the plan was to have one large wallpaper of 7200px x 2560px (5 screens @ 1440p) split over the pages so it's effectively one large screen.

In the personalisation settings, there is an option to set the home wallpaper to have multiple pages with a different image for each page. However this option so far as I can see only allows for three pages to be defined and gives no option to set which page on the home screen is the centre one. So if I split the wallpaper in 3 pieces (lets call them A, B and C), it ends up displaying on the home screens as A B C C C.

Is there any way to change the wallpaper to have 5 different images spread across the 5 pages as A B C D E? Alternatively if I'm limited to 3 images, is it possible to change which is considered the centre page (i.e. have it display the images as A A B C C)?

I'd prefer not to do it with a separate app, but if not possible is there is free low-weight app that will allow me to do this?

But, if I visit the same site, for example " https://www.google.com " , with an another browser, for example Opera mini, that have a VPN integrated, it works perfectly.

The strange thing is if I use another connection, for example another Wi-Fi network, it works, also with the basic browser.
This problem doesn't happen with other devices, the modem/router works perfectly with all the type of devices that I have on my house.
I already perform a factory reset on my device and also a factory reset of modem, but the problem is still here.

Side load apps on android wear watch through iOS app
I am wondering if it's possible to side load apps on an android wear watch through Bluetooth debugging from the android wear app on iOS.

I have a Moto 360 2nd Gen and I recently bought an iPhone. I feel quite limited in terms of watch faces and apps In general.

Unfortunately, my watch doesn't have any ports as it charges wirelessly and the only way to sideload apps is by doing it through Bluetooth. Now seeming as there is a debug function on the android wear app for iOS (haven't seen this function yet, so correct me if there isn't) I can conclude that if i download the adb drivers for my watch, the computer can communicate with the watch, using the iPhone as a tunnel.

My main question is whether this is possible. I may have misunderstood something, in case of that please correct me and direct me towards the right way.

Thanks for your time, any help and suggestions are much appreciated.

问:
Why is Cortana failing to search online?
In case it matters: Samsung Galaxy Tab A 8.0, running Android 6.0.1 (plus whatever Samsung's put on top of it, too). Region is Australia.

Just got the Cortana Assistant app a couple days ago. Mostly just to try it out, but actually really enjoying it all so far. I even have it set as my default assistant app now, so that with one long home-button press, up she pops from any screen, ready to take my request. There is, however, one glaring issue...

If the app can't find what I'm looking for, it looks like it tries to find it online (which is correct behaviour, of course) but... it can't? To wit, I'll just type in something like "linkedin", it'll think about it for about 5 seconds, then this screen will come up saying "No results found for linkedin", plus generic terms for making sure I'm searching correctly, e.g. "Ensure words are spelled correctly", "Try rephrasing keywords or using synonyms", etc.

She can say jokes, put in reminders, do all the stuff she needs to do to integrate with other apps on my tablet. But when I ask anything which requires an internet search, she fails onto this screen.

I thought maybe it was some weird thing to do with Bing, so I then did things like install the Bing app, made Bing the default search engine in the Android settings, then restarted the tablet, but that did nothing (I didn't think it would do anything - I thought if Cortana relied on having another app installed then she would've just told me rather than having this generic "no results found" screen - but I thought it was worth a shot).

I also looked extensively online, but I couldn't find any answer to this particular problem.

So... Any help?

EDIT: Hmm, it seems like Bing can be reached, or not quite? Now it's getting stranger...

It looks like Bing can be reached, possibly, because if it's something that clearly was meant to be a search, it will occasionally show Bing Ads above the message telling me that nothing could be found for the query. However, the Bing ads are definitely related to the query I entered.

Other times, if it's looking for something, the screen which is obviously meant to show results from a search is just completely white/blank.

Something else is obviously going on here, but I'm still stumped as to what...

Screen privacy : Xposed module for keeping away prying eyes

Anyway, searching for solutions lead me to BlackBerry Privacy Shade (amongst others ), which does an admirable job of blanking out portions of screen ( reasonable permissions ) , as you can see from pictures from Play Store. Other apps weren't as good and some had questionable permissions

How to Properly Reverse Boot Unlocking

No new ROMS were flashed, it was only used to get Magisk to install. This resulting in a warning that the bootloader was unlocked. So I thought it just needed to be locked again and I did it with fastboot. This unfortunately resulted in another warning which says validation failed.

How to add adoptable storage on android 6
I read an article claiming that on android 6, it is possible to format an SD card as adoptable storage (about time).

I have an ASUS Zenfone, with a PNY 128Gb SD card.  I have used an identical card for some time as external storage, but that's not very useful.

First, in settings -> System ->About indicates that the system is running Android 6.0.1

The article claims Settings -> Storage and USB, that I can click on the device, and it will offer to format as internal storage.  The only option I can see is portable storage, there is no choice for adoptable.  After I format, there are only two choice, eject and format.

How can I get the system to adopt the storage?

I found a video claiming that ASUS disabled the feature, and showing how to use adb and enable it by hand. Before I do this, I want to know if there is any easier way, and if there is any potential problem, including what might happen at the next upgrade.

Last, any idea why ASUS would do something as obnoxious as disabling a major feature like this?

Battery Drains Way Too Quickly. What's Going On?
I know there are many forums and posts already discussing battery issues, but I am posting here because I would like constructive and detailed feedback.

I have a S7 Edge running Nougat 7.1 not rooted, and a couple months ago, the battery used to drain by 5-10% overnight. Now, it drains by about 20-30%. I have tried different things to try to pin down the issue and/or alleviate it, but none seems to have worked.

Note that I have used the pm uninstall to get rid of some known bloatware and services.

I have tried 1) factory reset, 2) booting to Safe Mode, and 3) wiping the cache partition. The attached figures show the battery status at night and then the morning, and the captions indicate what action had been performed that night. I have pictures for all actions, but due to my reputation I can only post 2. Basically, the trend is that Android OS and Android System seem to always be in the range of 5-12% battery usage by the morning.

After all these methods, I really don't know what can be going on. Another interesting observation is that I lose more battery overnight, than during the day if my phone is just sitting in idle mode. Any constructive help/advice would be appreciated.

Update: Usually, the battery plot needs to stabilize overnight, indicating the phone is in deep sleep (or doze mode). I am thinking my phone is not able to reach doze and/or stay in that mode for a long time. Any ideas on that? I already have optimized all my applications.

Connecting S7 to home wifi brings the wifi down
I have a WiFi network at home and several devices connect to it fine. As soon as I connect my phone to the wifi, all other devices and my own get disconnected after a couple of minutes. After this the wifi becomes unavailable for hours. I can still use the internet with a wired connection but the WiFi is gone. I have tried switching wifi channels and any other settings but nothing works (including restarts). Sometimes if I power down my phone the wifi comes right back up and all other devices can connect again, sometimes it takes a few hours. </p>

<p>I haven't been able to key any pieces of this together. My phone, which is a galaxy S7 edge is clearly the cause but I can't understand why. </p>

How to force sleep after a timeout regardless of app?
I'm letting my little kid use an old Android phone (Galaxy S5) as a camera. I've got the camera app pinned so he can't do anything except take pics. He hits Home to wake it up and then can tap the screen to take pics to his heart's content.

The problem is that the camera app keeps the phone awake and screen on, bypassing whatever the phone's global options are. Apparently the screen stays on forever, too. I'd like it to have a normal timeout so kiddo doesn't need to remember to hit the power button. (Worst thing in the world for him is to have him pick up his 'camera' only to find it has a dead battery, right?)

Unfortunately there's no option in the Samsung camera app to change this. The system sleep setting is ignored. I tried a few apps that will auto-change screen timeouts based on app, but it has no effect - the camera app overrides this. I tried a couple other camera apps, but they have the same result. Anyway I like the Samsung camera - it's really easy for my kid to manage.

How can I force this phone to go to sleep after x seconds of inactivity, even when a camera app is running?

Is this a job for Tasker? (I haven't tried that yet - really complex app last I messed with it.)

Android devices not able to access the internet when certain router is on
I have a TP Link Router model TL-MR6400 and then to extend this wifi I have a Eircom D1000 modem, which is set up in Bridge mode. All my devices are able to access the internet using this setup(Windows laptop, Macbook, IPhones, printer, etc) except for the three android devices(A HTC 10, a HTC M8 and a Asus Tablet). All three of these are able to connect to both of the routers however when the Eircom D1000 modem is on then they cannot access the internet. When turned off my android devices are able to access the internet properly within three seconds, so I am confident that this is the cause of my problem. On all other wifi networks I have been on this problem does not arise.

Sometimes however these devices are able to access the internet, this can happen randomly throughout the day and lasts from 5 minutes to a few hours. Usually though the internet speed is much slower on them than on other devices.

This leads me to believe that the problem lies in the DHCP Server as when the devices are connected but not able to access the internet they are not appearing in the DHCP client list on the TP-Link. On the Eircom router the DHCP Server State is set to DHCP relay and DHCP Relay Server Address is set to the TP-Links IP.

Somethings I have tried already are changing the TP-Link's primary dns server to googles(8.8.8.8) as advised in this question and assigning a static IP to the devices as advised here. Both of these didn't help.

New Disadvantages of Rooting since 2010?
We have great a question from 2010 with some great answers about potential issues arising from rooting but newer versions of Android have become stricter about rooting and now allow apps to do some device checks.

What new disadvantages are possible since 2010?

From answers to the linked question, we already knew then that rooting can potentially brick a device, void its warranty and stop updates. I've also recently encountered SafetyNet which can cause an issue but have no idea what else I got myself into since rooting my phone.

Unable to connect to VPN through OpenVPN app
I have imported the .ovpn file, but when I try to connect I get the following error:

```<code>OpenVPN core error: option_error: cannot connect via TCP-based proxy
because no TCP server entries exist in profile.
</code>```

I have not messed with my phone in anyway (root, etc). It is just as I bought it, if that helps.

Can anyone help with this?

"device isn't compatible with this item" - why?
I would like to download and install this app on my Samsung Continuum SCH-I400 running Android 2.2.2 but instead of a download button, the Market displays an error message that reads:

Your device isn't compatible with this item.

I checked the minimum requirement for this app and it says Android 2.2. Why would Android Market flag it as incompatible with my phone?

Is there a way to get from the Android Market more details about this incompatibility?

What do I need to add or change in my Samsung Continuum SCH-I400 to make it compatible?

Can I change the NAT type when using my phone as a tether for Gaming?
I want to play online with my Switch while I'm on the go, but it seems my NAT type is D, which is too low to enable online play.

So is there a way to change that NAT type while tethering to my Android phone? Can I change the NAT type from my phone, or do something in my Switch parameters to force another NAT type?

PS: If the solution could not involve rooting my phone I'd prefer it.
