how could I store Big file (30G of like) on an external SD?
I need to store on an android tablet or phone some big file : about 30G. To be read by an app as a database.
but because of Fat32 simple copy just fail after 2G.
Could I format my external SD under linux ext2 ? is NTFS format recognized ? Do I have a chance to carry such a file on an external SD ?

Generally this is not possible, external storage in most android versions and devices must be Fat32... Can you be more specific as to the device and Android version?

hi, I am not locked in a device or android version. I need to use kiwix with some ZIM database on some place were no internet is accessible. I can chose a stecific device but I can not reduce the size of the ZIM.

rooted phone can mount ext4 formatted MicroSD Card

nice @alecxs , I am not sure a rooted device will fit. still need a hardware guarantee

i can only guarantee its definitely not possible without modifications. the phones internal storage however can be extended with external sdcard (adoptable storage) but you must not remove this sdcard

@alecxs is an external USB disk a possible solution ?

the problem remains the same, you must place the ntfs binaries somewhere. i have found only this without root but does not work for me http://techapple.net/2016/08/how-to-readwrite-to-ntfs-disks-on-usb-otg-in-android-no-root-enable-ntfs-mount-without-rooting https://www.paragon-software.com/free/exfat-ntfs-fat32-hfs-android

@alecxs it looks a good solution to transfer data. my problem is that I do not have enough space on internal storage so I need a system wide enabled external space. I guess I have to root a tablet. thanks for the links.

As you mentioned you're developer? of a app, there is a Tutorial about adoptable storage shared from @yoloxolo you might be interested. You should be able to access adoptable storage from your app, this gives you enough space on a ext4 file system https://android.stackexchange.com/questions/213312

I am not a dev. @alecxs

Did you try exFAT? On which Android version and ROM you are? exFAT was natively added to Android Pie (not through FUSE): https://android.googlesource.com/platform/system/vold/+/refs/heads/master/fs (kernel must have exFAT support). Some custom ROMs do have NTFS support added to vold through FUSE. If your device doesn't support exFAT, you can try this module which replaces stock vold binary with a custom one: https://github.com/Magisk-Modules-Repo/vold-posix (requires Magisk root). Also with root access you can manually mount any removable storage with ext4 filesystem.

How Does Google Maps Detect Compass Accuracy?
Modern versions of Google Maps display a cone of various widths for the compass, depending on how accurate/in need of calibration the compass is.
Given that the compass is simply a magnetometer and could be detecting either real magnetic fields external to the phone or calibration errors/magnetic fields coming from inside the phone, how does Google Maps know how accurate/well-calibrated the compass is at any given instant?

I've been in situations where a nearby strong magnetic field gave me incorrect compass direction. I'm not sure how accurate that "view cone" is on Google Maps beyond a general "the app believes that you are facing in that direction"

fastboot commands don't do anything mtk device
I have an android device, locked / not rooted. I'm trying to unlock the bootloader on a mac, adb works fine.

adb devices
adb reboot bootloader

works ok
But then when I try most commands with "fastboot" it won't work,
the only thing working is:

fastboot devices
fastboot --version

fastboot version 28.0.3-5475833

when I try:

fastboot getvar all
fastboot oem get-bootinfo

It just goes to a new blank line, then stays there "frozen" until I cancel...
same happens with

fastboot oem unlock

edit,
I see that MTK don't need to unlock?
IS this correct?
Thanks!

Apart from MTK specifics: fastboot only works when you're booted into the boot menu – where adb commands won't work (and vice versa).

So you mentioned that
fastboot devices

is a command that works for you, but you didn't mention whether or not you saw any output from your device. While I don't have a lot of experience with MediaTek processors, I'm aware that most of them share the same set of drivers and as a result, you should be able to download the appropriate "universal" USB drivers for Mac.
You won't be able to run
fastboot oem unlock

because your computer doesn't currently detect a device that's plugged in, even if your phone or tablet is displaying the bootloader screen and is connected to your computer over USB.
What I would recommend is Googling the name of your device and the words "USB drivers for Mac" in the same search query and installing the drivers from the manufacturer's website that comes up, or if downloads are provided by XDA or Reddit, from those sites as well.
From Googling, this link: https://forum.xda-developers.com/showthread.php?t=1917237 comes up that mentions that macOS doesn't require fastboot drivers, but I don't believe that is true anymore, although if that is the case and you cannot find drivers, I would redownload the Android SDK from Android Studio and use the latest version of fastboot from the platform-tools folder.

hi @Gideon, thanks I will try that, but my question is, I can connect to ADB, so will the fastboot need an extra driver?

@manuelBetancurt At least on Windows, it does need extra drivers; Mac should not. And my experience with Nokia phones also tells me that old versions of fastboot will not support newer devices. If you know the vendor ID of your phone manufacturer, then adding it can help: fastboot -i {vendor-id} devices

Recover manually deleted call history
I was looking for an outdated third party call backup app which does not update instantaneously at the deletion of logs via the default phone app. Would that be necessary or is there any other way I can save the said deleted history?
If yes, could anybody suggest such apps? Thanks!

there are no apps (as in an android app) to my knowledge but you can look at the binary data because what youve done is a soft delete and you need a hard delete to erase that information off the physical memory..
long to do and could be draining since you have to translate the binary also into higher level form .... you need a compiler for this. thats AFTER you find the location of the binary anomaly youre looking for (you can do this after too, thatll be easier, but youd have to decompile alot more code)
as long as your computer (in this case android) hasnt replaced that unused space (ie you havent downloaded too much information since) then its possible
im sure there are programmes to recover your code as i used to use these kinds of programmes since like 1997.
good luck finding that in 2019
but if you do btw... let me know.. thanks

This is unlikely to be possible. Disk recovery software requires raw disk access which is only possible if your device is rooted.
Moreover, unlike regular desktop computers, your Android device is likely using SSD instead of hard-disk. Data recovery in SSD is a lot trickier than hard-disk due to wear balancing. However, the killer here is that your SSD device is likely TRIM-enabled, unlike with hard-disk where deletion simply marks the space as unused, TRIM will wipe the space moments after deleting the file.

How to create a VPN config file for sharing with others?
I've a VPN server and want to let others connect to it.
I'm not sure if it's possible, but I'd like to create a VPN config file with all the necessary credentials so that my friends can simply open it and have a VPN profile set up.
Is it possible to make a config file?

Which VPN (protocol) server you have set up?

@IrfanLatif L2TP

I have never come across a VPN configuration file other than OpenVPN. They have a kinda standardized .ovpn format. I have an OpenVPN server and I create configurations using a shell script. My friends have just to import the file in client app, no manual entry at all. L2TP has very minimal configuration and clients usually (AFAIK) don't support importing saved configuration. Check with your client apps (I suppose on Android) if they have some option to import configuration. Then a standard configuration file can be created.

Force proxy to be used by all of my Android applications
I'm looking to force some applications on my phone to use a proxy whose certificate is installed on my phone. Some applications (like Instagram, YouTube, etc.) are using this proxy and I can sniff the communication between my phone and the proxy.
To make this work, I need to use root permissions on my Android. I found an app that may help me do this, but I want to use the terminal to achieve this.
Any ideas that could help me would be appreciated.

IMHO your approach is wrong. You will never be able to force every app to use your proxy. Therefore use a separate network that is connected via transparent proxy to the Internet. Then you don't have to configure anything on the device.

@Robert thank you for your response. If I'm not dreadfully wrong the proxy that I am using uses a VPN to encrypt the data coming from my applications, the VPN then send those data to a VPN server that will decrypt them and finally transmit them to my server. So I already have a separate private network that is automatically created by the proxy. I'm trying this new approach because it was suggested here and it seems to be efficient.

Can be helpful: How to set up a socks5 with Android cli?.

HTTP Toolkit does this using an Android app that uses the VPN mechanism to proxy all traffic through your HTTP Toolkit server.

Prevent a file from being overwritten
An app, due to an unfixed glitch, keeps overwriting an important file
How to lock that file so that it cannot be overwritten ?
Have root. Don't have xposed

You can remove write permission on your file. You would need toybox (inbuilt in Android since v5.0) or busybox. Assuming you have toybox already, use these commands in a terminal emulator:

su
cd /data/media/0/DIR              # replace DIR with wherever your file is. E.g. if the file is in /sdcard/Download, then DIR should be Download, so that the whole command looks like /data/media/0/Download
toybox chown 444 FILE_NAME        # this would set read-only permission for every user in the system for that file. Change 444 to 666 to revert changes.
chattr +i FILE_NAME               # alternative to above command. This prevents writing as well as deletion of the file. Change +i to -i to revert changes.

If you're wondering why the commands are performed on file under /data/media/0, read the answer here from Irfan Latif.

Thanks. Your answer works fine. I used Busybox (playstore). In my Android 4.1 I didn't have to navigate to /data/media/0 before my dir

Solution 1: Move the file to another folder. Thus, the app won't have access to it and can no longer change it.
Solution 2: If the file can't be moved (maybe because you don't want to move it, or that the app needs to access it from that folder), change its permissions to read-only. Any good file manager should be able to do it. click on the file, select properties then remove the write permissions.
Solution 3: Use a terminal and make the file immutable as stated in the comment using the command:
su chattr +i /path/to/your/file

Bear in mind that the second and third solutions will work only if the filesystem accepts the change of permissions or flags.

Unfortunately, setting a few R-W flags with a file explorer was not enough (ES File Explorer in my case). The app (which uses the file, and needs it where it is, simply replaces it).

I didn't test your commands (They require Linux, everyone!). Having it, it probably works.

Flash the BTU version for your ROM. Download and full Instructions on fw.updato.com
Flash TWRP (tar) via Odin AP. Download and full instructions on forum.xda-developers.com
Immediately reboot into recovery without ever booting into system. If you boot into system this will brick your phone and you have to flash stock rom again.
Format Data from TWRP recovery (Wipe -> Format Data -> type yes). reboot recovery.
Now copy the following files via USB (MTP) to Internal Storage.
Install the no-verity-opt-encrypt.zip or Disable_Dm-Verity_ForceEncrypt.zip from TWRP. reboot recovery.
Install Magisk zip. reboot system. wait for the boot about 20 minutes. you are rooted now.
Note: If you see errors in TWRP, goto Advanced -> Copy Log, get the recovery.log from USB (MTP) and find the more detailed Error Messages

Device storage gradually increases after Android update for no reason
I have an Android smartphone whose internal storage memory get incrementally bigger after every software update for no obvious reason. I have looked everywhere over the Internet but the answers were pretty much suggestions that I have already encountered and tested.
The phone's memory is around 16 GBs. During each and every of the last four software updates the memory stands at about 14 GBs, leaving room for almost 2 free GBs. As several of my apps in the SD card get updated over the next days, they are normally saved in the phone storage and then I move them to the SD card once the update completes. During the course of approximately a month, as more apps are getting updated and consequently moved the storage gradually climbs up to nearly 15.5 GBs and my phone displays limited storage error and everything else that comes with it (e-mail does not refresh, no more apps get updated etc.). The only solution that seems the erase the memory back to the 14-14.5 GB range is another Android software update.
What I have tried so far (daily basis):

Moving apps and old/unused files to external SD card.
Cleaning cache from Android Settings, cleaner applications and by
wiping the cache partition (blue screen as Android boots).

is it related to also increased data usage?

I don't think so, data usage increases normally according to my usage of the 3G network. Do you have anything in mind?

Nope. My problem is different https://android.stackexchange.com/questions/211929

But you can inspect your phone storage https://android.stackexchange.com/questions/210216

I think I broke my phone while trying to root it
I tried rooting my phone a few minutes ago and it ended up erasing my data but now it keeps trying to reboot but it never makes it past the "Samsung galaxy j5 prime" screen. help? is there anything I can do to fix this?

Could you include the steps that you did?

You have bricked it.You have to flash Stock ROM.Download the Stock ROM for Samsung galaxy j5 prime and Burn it.

Samsung's are notoriously hard to gain root access on, and many people that own a Samsung prefer to use a separate device with root access.
The main reson is that Samsung's main goal ( in my opinion ) was to create a device that is secure enough to be used by law enforcement agencies.
The main selling point in that direction was a security feature called Knox, .. Knox is supposed to stop any modifications that could expose the devices sensitive data, if you do gain root access, it is usually by removing knox or disabling it somehow.
Usually to do this is to exploit the system and a specific vulnerability that will allow root access.
Gaining root access on a Samsung will disable many features that require a secure device, like payment methods for example.
You need to use a program called Odin to restore your Stock Firmware and then consider either using a different device or using a custom firmware that has root access already.

How to make full backup?
My phone is a Nokia 6.1. I'd like to do a factory reset, but preserving:

my personal files
the settings of all apps
the data saved by all apps (e.g. the alarms saved by the stock Clock app)
the collection of apps (I want them to be reinstalled after the reset)

Does the "Settings -> Advanced -> Backup" Android feature do all that? If no, then what part does it do?

And no, Google backup doesn't cover all. Especially when you consider restore.

Found the answer here:
If you back up to Google Drive, here's what's backed up:

Google Contacts data
Google Calendar events and settings
Wi-Fi networks and passwords
Wallpapers
Gmail settings
Apps
Display settings (brightness and sleep)
Language and input settings
Date and time
Settings and data for apps not made by Google (varies by app)
Note: Not all apps can back up or restore all settings and data. To find out about an app, learn how to contact its developer.

How to fix “fastboot FAILED (command write failed (No such file or directory))” error?
I was trying to flash TWRP recovery image in my MI 8 SE on my windows 10 laptop. I can detect my device in fastboot mode, but when i try to flash the image i get this error
target didn't report max-download-size
sending 'recovery' (25668 KB)...
FAILED (command write failed (No such file or directory))
finished. total time: 0.008s

My phone then exits from the fastboot mode and i get a black screen with a tiny text at the top left corner of the screen "Press any button to exit" or something like that. When i try to flash the same recovery imaget on my windows 7 pc it flashes without any problem. Not sure what the problem is i've tried installing drivers for the phone and trying different usb ports but nothing help. I can detect the phone when it's turned with no problem.

sorry did not read. this question is not related to android

maybe you should use fasboot from cmd.exe instead of powershell

Is there a way to enable USB debugging from fastboot?
I have a Nvidia Shield Tablet that froze on me. After powering down it hangs on the nvidia boot up screen when I try to boot it up. Nvidia support says it is a 'soft-brick', as I can't get into recovery mode from fastboot. I am trying to get a recovery image on the tablet. However, the bootloader is locked and I'm pretty sure USB debugging was not enabled ahead of time. Therefore, I can't perform an unlock using adb, and so can't flash a recovery image. When trying to access through a platform-tools terminal, it doesn't show in a list of adb devices.
I'm pretty confident I have the correct drivers installed on my windows PC, which is connected to the tablet via USB.
Nvidia Shield Tablet Wifi (2014 version)
Any help is appreciated at this point, I can't think of anything else to try. Sorry in advance for mixing up terms etc. I've just been researching the past few nights and trying to find a solution. I'm far from an expert.
I've tried these links, here and here but they seem to require USB debugging enabled or ability to access recovery mode from fastboot.
Thanks,

Nvidia support is wrong. it is not a 'soft-brick' it is a hardware failure

you have serialno, try to claim the battery maybe you will get a replacement https://www.nvidia.com/en-us/shield/support/tabletrecall/

when your serialno is between 0410215901781 to 0425214604018 you will get a new tablet for free

adb and fastboot are different modes. you can enter recovery without usb debugging. Press and hold Power + Vol Down. This is the bootloader screen. Now navigate to recovery with Vol Keys, Power to confirm. Wait a Moment. When the android symbol appears, press Vol Up + Power to enter recovery. Now do Factory reset.
If device is locked you may not be able to enter recovery. you can unlock it from fastboot and try again. Unlocking will factory reset your tablet. Download platform_tools from google. Enter fastboot mode from bootloader screen. Connect the usb cable. Install the drivers. Open the cmd.exe as administrator. navigate to the folder. check with fastboot if the serialno appears. unlock.
fastboot devices
fastboot oem unlock

then boot TWRP and see if partitions can be mounted. at least /system and /cache should be mountable, otherwise something is wrong. /data is encrypted but should be mountable too. for more info see here. Do not flash TWRP to recovery partition, first backup stock recovery!
fastboot boot twrp-3.3.1-0-shieldtablet.img

in twrp, there is a option reboot recovery which should you bring to recovery mode. if not, you still have to option to backup/wipe partitions from twrp. start with wiping cache. if phone is still not booting, reboot into twrp and format data. if any error occurs, you can pull the log from adb at any time. post the log file in the twrp support thread and ask for help. try another twrp version (3.1.1-0) depending on your android version
adb pull /tmp/recovery.log C:\Users\Admin\Downloads\platform_tools\recovery.log

if you need to enable usb-debugging from recovery, you may modify /system.
(but also the other methods you linked above should work)
pull the /system/build.prop and edit the following lines with Notepad++ (make a copy for backup)
persist.service.adb.enable=1
persist.service.debuggable=1
persist.sys.usb.config=mtp,adb

mount /system writeable, then push it back to phone. if you don't want to modify /system you can try to push it /data/local.prop (but i guess it is not supported on this rom) or do create a file /data/property/persist.sys.usb.config (i don't have exactly read this posts above)
adb push "C:\Users\Admin\Downloads\platform_tools\build.prop" /system/build.prop

Now place the RSA-Key somewhere on the phone and merge it into adb_keys
adb push "C:\Users\Admin\.android\adbkey.pub" /tmp/adbkey.pub
adb shell
mkdir -p /data/misc/adb
cat /tmp/adbkey.pub >> /data/misc/adb/adb_keys

if root access is required, you can change ro.secure=0 in build.prop too (but not recommended)

https://youtu.be/V9XpykHyJiA
https://docs.nvidia.com/gameworks/content/devices/shield_flashing_from_image.htm

Thanks very much for your reply. I initially tried navigating to recovery the method you outlined, however the Vol Up + Power has no effect when I'm on the android symbol screen - it just says "No command". I can see the serial number when I run the command terminal and use 'fastboot devices'. 'fastboot oem unlock' actually appears to be doing something. I see... erasing userdata...erasing user data done...erasing cache...erasing cache done. unlocking... but then it just hangs. I've left it go for 10-15 minutes. If I cycle power it's still locked. Appreciate any further input :)

maybe this triggers FRP Lock but this can be solved from twrp

Trying to boot TWRP returns an error: "FAILED (remote: 'Bootloader is locked.'). I admit you lost me a bit with the /system modifying. Not sure what you mean by 'pull'. Is this performed with an adb pull (like you have suggested to do with the log file?). I still can't get the device to be recognized using adb, so I'm not sure this will work. I'll have to read more about it tomorrow. I don't expect you to be too hand-holdy, but I appreciate your help.

You don't need usb-debugging, it is just to fulfil the question headline

Haven't found a solution yet, but here same problem https://forum.xda-developers.com/showthread.php?t=3178865

it should be possible to unlock from linux. but this is for experts only. unfortunately i haven't found a tutorial for this. https://github.com/NVIDIA/tegra-uboot-flasher-scripts

I can't permanently delete or download files
Whenever I try to permanently delete a photo in my photo gallery, I get a message saying "Can't delete from device." I've tried deleting files by plugging my phone up to my computer, but the files keep coming back sometime later after they're deleted. Not only that, but I'm also unable to download images or apps. Whenever I try to download an image or app it says "Download Pending" even though I have 114 MB of space free. Is there a way to fix this?

114MB free is not much. Also it can be free space on the wrong partition. Use an app like DiskInfo to check the free space on your partitions.

if you can not install apps, try if you can enable usb-debugging. from adb shell check the output of mount data and sdcard is rw. if it is ro (read-only) you probably have serious problems with emmc

I got a similar issue. When I delete photos from the gallery I get a message saying it deleted but when I check the gallery again those are still there. And also When I get new photos those are not saving in the gallery.it's a Samsung J1. finally, I did a factory reset and the problem was solved.

Why does sim tool kit is not appearing?
I'm using Asus Zenfone Max Pro M2.
Running on stable pie.
But sim tool kit is not appearing in my phone.
Does that mean my sim card is corrupted?
I face slower download speed using it.
So when I've checked other sim card of same operator then there's no issue.

The SIM tool kit may not have a lauchable activity, so it would not appear in launcher app, but should appear in system apps list under Settings app. Also, I don't think there is any correlation between it and download speed.

But I experienced such thing if it is not appeared. It is present under system app.

When system app would be in launcher sim tool kit is appeared only when sim is inserted so I'm sure sim is corrupted.

No one can hear me on my Galaxy Note 8 Edge! How do I fix?
No one can hear me on my Samsung Galaxy Note 8 Edge when they call me or I call them.  I hear them clearly, but I have to race to turn the speaker on before they hang up.  How do I fix this problem when it seems my mic works fine when I use an app to record myself

Most apps use secondary source to capture audio when the primary source is down. The source switching is automatically done and, in a phone with good memory, might be seamless.
It is highly probable that your Mic (primary audio source) is down. When recording, the app might actually be switching over to secondary source for audio (which might be the loudspeaker). My advice is that you change the Mic of your phone.

Carrier apps still appear after stock android installation
So I have been trying to install stock android on my phone, but not having the desired result. Before I try on my current phone (Galaxy S9), I've been practicing on an old S6 edge.  The phone was bought in Canada, and has the Telus build on it from the factory.

Downloaded Odin (version 3.13)
Downloaded the firmware from Sam mobile (specifically, I have picked the XAC, carrier agnostic product code)
Flash with Odin
Reboot and wipe cache partition
Factory reset

But when I restart the phone - BAM! Telus bloatware remains installed.
Any idea what I am doing wrong, and how to do it correctly?
Edit: clarified question

Samsung have its own partition /preload for its bloatware which is usually not wiped on factory reset

If you really want to remove them, get root access on the phone and install Titanium Backup form the Google play store. Make sure you have unknown sources turned on. Open Titanium Backup, wait for it to set up, then select Backup/Restore at the top. Find the app you want to remove, and select it. On the menu that appears, tap Backup at the top of the menu, so if anything goes wrong you can try to restore it. Then press "Un-install !". After it's done, reboot your phone. If all goes well, you can go back to the list of apps, find the backup you made, and delete it.
!!WARNING!! IF YOU DELETE AN APP REQUIRED BY THE SYSTEM, YOU COULD SCREW UP YOUR ROM AND HAVE TO REFLASH IT! YOU HAVE BEEN WARNED!!
Edit: this probably isn't a good idea

rooting is not a good idea especially with samsungs vaultkeeper these days

(Lenovo A1000 MTK MT8317 only) Next time, first make a full read back. flash only cache partition from SP Flash Tool.

True, i have mixed up. Seems not all Lenovo are MTK. When fastboot formatting does not solve it, try booting twrp from fastboot. twrp has adb access, you can format cache manually with mke2fs

do not flash, try fastboot boot TWRP-3.0.2.0__A1000__by__nemo-nemo.img and in twrp adb shell and post output of ls -l /dev/block/platform/*/by-name

Try clearing the cache partition using Recovery Menu. After you open Recovery Menu (search methods online), navigate to Wipe Cache Partition using Volume UP and Volume DOWN buttons and then press Power button to select Wipe Cache Partition. Wait a while till it finishes wiping (if it doesn't fix the problem, try wiping again and flashing and fastboot, as said in other answers)
I'm having the same problem btw, I read this online but not sure if it works so let me know if it does!

I'd like to ask if there is a way to backup all my apps and data to transfer from miui to a custom rom. I've switched before, on another device but had to reinstall everything, which was pretty annoying, thus losing all my app data. I was wondering if there is an app which just backups everything, including contacts, messages, apps and app data, etc and then restoring everything back to normal. PS. I have gained root rights.

https://forum.xda-developers.com/showthread.php?t=3862763

Such an app would require root, as otherwise it hasn't access to "everything". Coming very close is e.g. Helium Backup, using a trick via ADB. Or you can use [tag:adb] backup directly – or use my tool Adebar to create a backup script for that. Won't cover "everything", though: apps + data yes (unless the dev has made his app opting out of backup). Contacts + messages you'd need to transfer by other means (the contacts app allows export and import, for example).

@Izzy right. I forgot to mention that I have gained root rights on the device. I'll edit it straight away. Though helium setup didn't work, as it kept asking me to switch to ptp and that my device was on mtp when my device was actually on ptp.

@alecxs thanks a ton!

Well, if the device is rooted things look a lot different. Ever heard about Titanium Backup? I use that for about 10 years now and migrated with it many times. It's definitely worth the 5 bucks license key to go "full featured" and use all the batch stuff (though for restore I still prefer the manual way, one thing at a time). TiBu would cover "everything" you've mentioned.

After I tried using the migrate app, which force closed everytime I tried to enter system apps, I went on with an app I had lying on my phone, called app2sd. I've backup up everything and I'm good to go. Thanks everyone. Case closed

Pixel Launcher crashing due to missing STATUS_BAR and MANAGE_ACTIVITY_STACKS permissions
I'm running LineageOS 16 on a OnePlus 3T. Whenever I try to open the Pixel Launcher, it crashes. In adb logcat, I saw the following lines that looked relevant:
05-25 16:13:31.293 16356 16356 W TaskStackChangeListeners: java.lang.SecurityException: Permission Denial: registerTaskStackListener() from pid=16356, uid=10003 requires android.permission.MANAGE_ACTIVITY_STACKS
05-25 16:13:31.476 16356 16356 E AndroidRuntime: java.lang.RuntimeException: Unable to resume activity {com.google.android.apps.nexuslauncher/com.google.android.apps.nexuslauncher.NexusLauncherActivity}: java.lang.SecurityException: Permission Denial: setShelfHeight() from pid=16356, uid=10003 requires android.permission.STATUS_BAR

I tried running these commands to fix the problem:
adb shell pm grant com.google.android.apps.nexuslauncher android.permission.MANAGE_ACTIVITY_STACKS
adb shell pm grant com.google.android.apps.nexuslauncher android.permission.STATUS_BAR

However, they failed:
java.lang.SecurityException: Package com.google.android.apps.nexuslauncher has not requested permission android.permission.MANAGE_ACTIVITY_STACKS
java.lang.SecurityException: Package com.google.android.apps.nexuslauncher has not requested permission android.permission.STATUS_BAR

I searched for this and found a post on XDA with someone having the same problem: https://forum.xda-developers.com/android/software/pa-gapps-continuation-t3098071/post77695616#post77695616
Responses weren't very useful though. They basically boiled down to "your ROM is broken; ask your ROM developer to fix it."
So how can I fix this crash?

I rebooted into TWRP and edited /data/system/packages.xml. Under <package name="com.google.android.apps.nexuslauncher" and <perms>, I added the following lines:
<item name="android.permission.STATUS_BAR" granted="true" flags="0" />
<item name="android.permission.MANAGE_ACTIVITY_STACKS" granted="true" flags="0" />

When I rebooted back into Android, the crash was fixed.

Very strange: 1. I don't have a <perms> but <permissions> section under <package name="com.google.android.apps.nexuslauncher" 2. In /data/system/packages.xml I have:

I had the same issue with after an upgrade to LineageOS 17.1 on OnePlus3T. In addition, using another launcher the "recent apps" button didn't work.Searching the XDA forum for the relevant version suggested re-applying Gapps. I just made a new update of Lineage (latest daily) immediately followed by the latest OpenGapps. After this all worked fine.
Looking at the changelog of OpenGapps, Pixel launcher FC was a known and fixed issue.

How can I put location in "Battery Saving" mode in Android Pie?
In Android Oreo, when location was on, there were 3 choices for how it worked: Device Only, Battery Saving, or High Accuracy. In Pie, it's easy to change to Device Only or High Accuracy by turning "Google Location Accuracy" on or off in Location settings. How can I change to Battery Saving?

Google has removed all of the UI from the OS to change this setting, but it's still changeable in other ways.
If an app has the WRITE_SECURE_SETTINGS permission, it can do this by calling Settings.Secure.putInt(contentResolver, Settings.Secure.LOCATION_MODE, Settings.Secure.LOCATION_MODE_BATTERY_SAVING);. The Tiles app in the Google Play Store includes a Location tile that does exactly this.
Alternatively, if you have ADB or root, you can do this with no third-party apps by running settings put secure location_providers_allowed +network,-gps from an ADB shell or a root shell.

WRITE_SECURE_SETTINGS permission is not for use by third-party applications https://developer.android.com/reference/android/Manifest.permission.html#WRITE_SECURE_SETTINGS

@Jim yes, but there's a workaround via adb to grant it to them anyway.

thanks~ i'll try, btw after putInt(LOCATION_MODE_BATTERY_SAVING) how can i use back to high accuracy mode? can i simply change it to LOCATION_MODE_HIGH_ACCURACY?

Cannot move app to SD card: "Not enough storage space"
Disclaimer: There are many similar questions, but: 1) No answer there helped me, 2) This one provides additional info and questions, 3) Others seem to be related to Android versions < 8, so the scheme looks different. So it wouldn't really help adding a bounty.
I am using Android 8. As far as I could find, I cannot install apps directly to SD card. I have to install them regularly, and then move them via Settings -> Apps -> Workplace (App info) -> Storage.
I mean to move Facebook Workplace to the SD card, and I keep getting "Not enough storage space".
I have plenty of space there (more than 6Gb).
The app shows as taking up 138Mb. I have 530Mb available in the internal memory.
What I tried:

Moving other apps to the SD card. It worked.
Removing and reinstalling Facebook Workplace. Moving to SD card. It failed the same.
Ejecting the SD card and inserting it again. I had to rebuild my home screen, but still cannot move the app.

What I did not try:

Formatting the SD card. I guess it is too much work to try, and many others reported it does not work.
Reinstalling the OS. It is a corporate device.
Rooting the phone. Ibid.
A custom ROM. Ibid.
Using an app. It seemed to me that this was required for older Android versions. Now Android has that capability builtin.

Other similar questions are:
Unable to move few Apps to SD Card .
This answer provides reasons why an app might not support moving to SD, but I guess Android 8 is already aware of this, and shows the option only if possible.
Plus, I wouldn't know how to tell if Facebook Workplace is one such app.
And none of this has an answer that helps me (many of these are very old questions):
Getting "not enough space" error even i have enough space in sd card
"Cannot Move App Not Enough Storage Space" Error Message
Cannot move app to sd-card?
Storage space in SD card
Getting "not enough space" error even i have enough space in sd card
why do I keep getting message saying unable to move app not enough storage space ?
Move app to SD card
Move apps to SD card in Marshmallow without using internal SD Card storage?
My apps don't move to SD-card
Move apps to internal SD card
"Couldn't move app. Not enough storage space." I have factory reset my phone, inserted & formated a new 64GB MicroSD Card
Why do I keep getting "not enough storage space"
More old questions:
App can't be moved to SD card
What does the 'Failed to move application. Not enough memory' error mean when choosing 'Move to SD card'?
"Couldn't move app. Not enough storage space." I have factory reset my phone, inserted & formated a new 64GB MicroSD Card

Why does npm fail in termux?
I have an Acer Chromebook 13 with Termux installed. I've run termux-setup-storage and I have nodejs installed (no errors). I'm trying to make a small node app under the downloads directory -- as termux references it: /data/data/com.termux/files/home/storage/downloads/_dev/base_app/api
I have created a package.json file there, and when in that directory, I ran npm i -s express
this seemed to run ok, but it didn't update the dependencies in the package.json file.
npm install express --save produced a long list of warnings (the same one over and over - tar EPERM: operation not permitted, futime) and then an. I failed to copy the error at that point.
then I tried running npm install mongoose --save had similar behavior. The error I got then was

side note: tsudo doesn't work. ANy command I run with tsudo tells me Permission denied.

It tries to create a symlink and fails – as symlinks are not supported by VFAT (internal SD card is presented as VFAT, via FUSE, despite of the underlying system being something else, usually ext4 nowadays).

does that mean a node based dev environment is going to be impossible without linux/crostini?

I cannot tell, I've null experience with NodeJS. That question is better asked in a NodeJS community. One possible solution I could think of is creating e.g. an ext4 volume (on a separate partition of the external card, or in a "container" – I've no idea on details for the latter, though), and locate your NodeJS stuff there.

Does this answer your question? Unable to install express ( of node.js) in Android termux using sdcard0 as directory

Moving Chrome saved passwords to Brave browser
Is it possible in any way to replicate Chrome passwords to other Chromium-based browsers such as Brave? I have a rooted device. I tried copying the "Login Data" file from the Chrome data folder to the Brave data directory. But Brave didn't pick it. And there is no option to import CSV passwords in Brave browser.
The desktop version of the Brave browser has an option to import CSV passwords, and I did that, but there is no option to sync passwords between the desktop version and the Android browser.

Reading Brave support page it seems that you need to

install brave on your desktop machine
Import your chrome profile https://support.brave.com/hc/en-us/articles/360019782291-How-do-I-import-or-export-browsing-data-
Sync your android phone with brave installed on your desktop. https://support.brave.com/hc/en-us/articles/360021218111-How-do-I-set-up-Sync-

So far, not yet. The Brave Dev team said it's on the roadmap, there are several overlapping issues (with sync, bookmarks, general browser data and specific password import/sync) but there has been no feedback from the Devs on an implementation timeline. Very frustrating. Brave is a great browser and has lots of potential, but if it's to compete with the other browsers it has to include basic features that users expect. Password sync, or at least import and export on mobile/laptop/desktop, is one of them. Payment, Address and other browser data would actually make it comparable to other browsers...

Using Android to Answer calls of iPhone
My primary device has always been an iPhone. But recently i saw android auto and it is way more responsive and offers a great experience.
So I am planning to get an android tablet for my car. But the problem is that if I connect the android and not my iphone then I would not be able to take calls coming to the iphone on my car's speakers. Is there any way I can do this, something like handoff?
Call forwarding is not really an option as it would always forward my call to android tab which I do not want. I just want the phone calls to come on android when I am in the car (or iphone is nearby the android tab).
Hope there is something like this available!

http://www.mrhandsfree.com/en/customer-service/product-faq's/blue-multi-how-do-i-connect-2-mobile-phones-at-the-same-time-(multipoint-pairing)

@alecxs thanks! I read the link, it is a hardware change required in my car. I do not want that. Instead, I am looking for some application which can do this. I own a Jeep Compass and it already has a pretty good Uconnect system installed.

Some sort of Bluetooth Headset application is all i can think of... The IPhone sends out a Bluetooth signal for Headsets to receive the call... This was also one of the first methods of In-Car stereo connectivity after FM Transmitters died out...

@Zillinium yes that should work for me, let me explore it a bit more. Thanks for the suggestion.

Will Android be able to install OS updates without Google account?
I am working with android phones at work, we want to remove all google accounts from the phones before we give it to our customers.
I know that the phones are not able to receive app updates, but what about os update from android?

OS updates are provided by the device manufacturer. They are retrieved directly by the device and don't require any user account.
The only requirement for an OS update is a working Internet connection and enough free space on the device.

I would correct it to device manufacturer and / or ROM developer.

Adding to the answer Android plans to provide security patch updates through play store in future called project "Mainline", so with advent of android Q you will probably need to have a Google account to install at least security updates. Also Google has been trying hard to streamline the OS update procedure across vendors so you never know.
Hope my answer added some value.

Does deleting your Android apps data delete your personal files?
I use Redmi Note 3 with Android 6.0.1. Out of 10 GB internal storage, 4.5 GB is occupied only by apps. I see that app data and app cache eat up a lot of free space. I safely delete app cache data.But since that's not enough so I want to delete my app data also. But all my files in my phone are important to me so I want to be sure that deleting my apps data won't delete my personal files. Some of the apps whose app data I intend to delete are Google play services, Google drive, Mi Browser and Google chrome. I am not sure what files does this 'app data' contain and I don't know if there's any method to know that.

To make an example, a browser's app data would contain e.g. your history and login information, among others. In other words, deleting an app's data is the same as installing the app from scratch, from a casual user's standpoint.

Clearing an app data DO delete files from your phone. Becuase those files are associated directly with the apps that you are deleting. Any other files which are not AUTOMATICALLY created by the app being deleted will not be deleted when you clear an app's data.
So, go ahead and feel free to delete an app's data. But be careful deleting an app's data actually resets that app into a freshly installed app state. And if you delete the Google app's data chances are that you might lose some bookmarks, history or any preferences you have set previously.

Lenovo tab 3 7" TB3-710F Android 5.0.1 won't start after installing wrong TWRP
Basically I wanted to root it and every TWRP I tried came up an error that the file was too big,. moments later I tried different versions..many other versions btw,, scaling down to the smallest in size was 2.0.1.2 I think..
Anyway, it got stuck in a bootloop for about 2 hours. Mind you the computer makes the beep everytime I connected it and reconnected, so I thought it's still alive. Now, it won't turn on and I've tried most of the method's to get it flashed but nothing even lights it up... brick
I have tried most XDA and Google without any possible fix.

Possible duplicate of ROOT Lenovo tab 3 7" TB3-710F Android 5.0.1. also to that's stuck in FASTBOOT MODE

I added it  it the notes with a link because they are different questions

the size of recovery partition is 16 MiB (hex 0x0000000001000000 = 16777216 bytes)

@alecxs Tried all that. I even tried different ADB commands. Error no device detected or waiting for device,...,........I even tried kingroot, to see if it would recognise anything...

Thanks for that really detailled answer, dear alecxs.. At first it didnt work because i had the wrong ROM , than i take the correct one , followed the tutorial really exactly from 1-20 and what should i say , i reanimated this Tablet which stucked in a bootloop a long while. Workes well now .. I struggled a little bit with Google Play Services which i cant update  but i kicked them after i rooted the tablet and reinstalled them manually again..
Thanks for this great tutorial

1 - download the latest ADB and Fastboot binaries
2 - install MediaTek MT65xx USB VCOM Preloader USB Drivers
 enlarge view
Note: This driver does only appear for less a second (and during flash/ readback) watch video
3 - install MediaTek SP Flash Tool
4 - install 7-zip
5 - download Stock ROM, extract it
6 - remove the checksum at end of (Stock ROM) MT8127_Android_scatter.txt (last two lines):
# [huaqin]
# checkSum = 0x0f5e

7 - open the (Stock ROM) MT8127_Android_scatter.txt file in SP Flash Tool -> Download
(and SP_Flash_Tool\MTK_AllInOne_DA.bin as Download Agent, if not already selected)
WARNING: Make sure not to "Format All + Download" devices with secure boot or flash using "Firmware Upgrade" option. This will damage/hard brick your device
8 - de-select the check box "preloader" (EMMC_BOOT)
9 - remove the battery

10 - click Download in SP Flash Tool
 enlarge view
11 - connect Tablet to PC using USB Cable
(Note: the flashing starts immediately when connected. if nothing happens, wait for the drivers recognized first time, disconnect and repeat from step 7)
12 - wait for green checkmark Download Ok
13 - insert the battery
14 - press and hold Volume Up Button
15 - disconnect the USB Cable (still holding Volume Up)
16 - reconnect the USB Cable (still holding)
(Note: you may hear multiple connecting sounds - don't release the Volume Up Button yet)
17 - when Android system recovery appears, release Volume Up Button
18 - select Reboot to bootloader with Volume Down, confirm with Power (or Volume Up sometimes)
19 - open the platform_tools folder from cmd.exe (as Administrator)
20 - unlock the bootloader by typing following commands:
fastboot oem unlock
fastboot reboot

Note: If you want to flash custom recovery with SP Flash Tool, recovery.img must fit the size 16 MiB.
If the bootloader is unlocked, you can test the recovery before flashing, then flash from fastboot instead:
fastboot boot "C:\Users\Admin\Downloads\recovery_twrp302_Lenovo_TB3-710F.img"
fastboot flash recovery "C:\Users\Admin\Downloads\recovery_twrp302_Lenovo_TB3-710F.img"

Tried all that. I even tried different ADB commands. Error no device detected or waiting for device,...,........I even tried kingroot, to see if it would recognise anything...

Sorry. I didn't see the reply brb

step 10 nothing happens I click download and everything just gets greyed out and I plug in the device and I can hear the sound but nothing happens absolutely nothing I've tried all different ADB commands to start server it says the server is out of date and also the device is not detected in a VB anymore after the bootloop I think I killed it

thats not possible except you flashed a wrong preloader. can you hear one sound, or two? open device manager (com ports): between the two sounds, can you see the driver for a second? i attached a screenshot

thanks for your patience this is really tricky one it beeps twice and here is the new image

https://i.imgur.com/ifYuUum.jpg

I don't think I've got the correct stock ROM for it each one I download has different codes at the end of them I've downloaded three different roms all for the same device this is really confusing I'm pretty sure I've got wrong rom. I think we're just going to start at square one and but I'm going to need a link if you can to the correct ROM file for this device because this is doing my head in at your leisure of course if you've got time I can do a Google search in the meantime but I've already got about 20  tabs open

the ROMs provided in answer are confirmed working. The two sounds indicating that preloader is still working, no worry it is not hard bricked. from your picture i can not see you installed preloader drivers. it is under (Ports COM & LPT), you missed step 2

ITS WORKING thanking you muchly. But can you pleas show me the steps to install the TWRP IMG file. I definitely don't want to brick it again.. my mind is like jelly and I lost the page of rooting it with the recovery img

Its all there, just follow step 20) fastboot commands

THANK YOU SO MUCH

How to delete app remnants without root privileges?
I installed Chrooma Keyboard on an Android Nougat device.  It worked fine, including swiping to enter text.
After adjusting Chrooma's settings several times, it started to have a problem where keyboard swiping always resulted in an exclamation point instead of a word.
No problem, I thought.  I cleared Chrooma's cache and data, and tried it again.  The swiping error persisted.  I then uninstalled Chrooma, cleaned the device using SD Maid Pro and CCleaner, and rebooted.  I thought for sure those steps would clear everything out in order to reset Chrooma to its initial state (and fix the bug).
But alas, even after taking all those steps, the bug in Chrooma (which was not present when it was first installed) persisted.  This indicates that it likely wrote some sort of configuration file to a storage location that was not cleared by clearing the app's data and cache, and even by uninstalling it.
Without root privileges, how do you completely delete remnants of an app?
Note: I only use Chrooma Keyboard as an example in this question... the question applies to any app.

Most likely the bug was introduced by an update of Chrooma. In such a case nothing you can do will change the situation. Contact the app developer for a fix.

@Robert Thanks for your comment.  It all happened within 30 minutes, and there was no update to Chrooma during that time.

Mac Fails to recognize my Android phone through USB
I installed ADB via homebrew but running adb devices returns an empty list. I also tried system_profiler SPUSBDataType but I still fail to find my device here. I don't have EasyUSBTethering issues on my system. After connecting to my iMac, my cell phone starts charging, but fails to start USB debugging even though I have turned both "Develop Mode" and "USB Debugging" on. The version of my MacOS is 10.14.4.
There is no problem with the cable because I can USB Debug with it on my PC.
I know this situation seems awkward. Any possibility is welcomed and please feel free for requesting more relevant information about my devices. Thank you in advance!

Finally it turns out to be a cable issue - but very weird! On Windows both USB 3.0 and 2.0 Cables are supported. On Mac, however, only USB 2.0 cables are supported. Initially I was using a 3.0 cable and thus by confirming that everything runs smoothly on PC, I directly denied the possibility of cable issues. I wish my sorrowful experience could help prevent some valueless efforts.

Can't launch Google Play Store from within other apps
Recently, I am having a problem with my Android phone. Generally, when an app tries to show something in the Play Store, the Play Store app opens up. But, recently I noticed that Play Store is no longer opening up from other apps, instead, I get an app chooser which asks me to choose between the two browser apps installed in the phone.
Screenshot:

When I choose a browser app from the app chooser, then also Play Store doesn't launch.
So, I think that the system can't find the Play Store app. What to do?
I have Micromax Q437 mobile with Android 7.0.

Check open by default setting for Play Store under Settings > Apps and tell us what is mentioned below Open Supported links entry. If it is Don't open in this app, than you know the problem now.

No, that's not the case. Under the Open supported links entry, Open in this app option is selected.

Export all WhatsApp Chats at once
how can I export all WhatsApp Chats at once, without having to click every single one of them to export it.
Can someone help me with that problem?
BR Sarah

There's no such functionality yet, so you're gonna have to export each

Isn't there a possibilty to write a clickbot for whatsapp web?

not that I know of

Is there any hack involving decrypting a WhatsApp back up on Google Drive? Or alternatively, a paid tool that does this for you?

The only solutions I've come across for this specific question: https://stackoverflow.com/a/15427040/6728517 Disclaimer: the answer is old and I haven't tested it. Having researched this a little, it looks like exporting chats individually is the only other option.

App Installation "blocked by your IT admin"? (Galaxy Note 8)
I use YMusic to listen to music/audio books, which is an outsider app from xda-developers. When I tried to install an update, I got the message below, as if YouTube is preventing me from installing the app. Here's a Screenshot:

I wanna mention a couple of things:

This is my personal device, so there's no IT admin
developer mode is enabled on the device
It's not the first time I install apps from unknown sources. Usually I have to authorize them during the installation, and this source is authorized
It's not a rooted device
it's the latest available version of Android, security update May, 1st 2019

EDIT: After a couple of days, that message didn't appear anymore. Maybe the app had something that conflicts with YouTube, and it was updated? I don't know.

Check the Android security settings for "device admin apps". These apps can restrict certain functions on your device, therefore this interface is at the moment used by IT admins to manage devices. Therefore I assume the massage assumes you have a managed device.

@Robert The only app enabled there is a "Find My Device" app... nothing with YouTube.

You misunderstood me. Device admin apps can block certain actions (like installing app xyz) on your device. But if you only have "Find My Device" active this can't be the source of the restriction.

While this is your personal device, did you log in with any managed account (e.g. work account)? Is "Device Policy" app installed?

@AndrewT. Nope. Absolutely unrelated to anything at work. Actually at work we cannot do that due to security procedures.

Is it possible to install an FM Radio application to get local frequencies?
Samsung Galaxy S10 has a built-in radio application. But it catches only USA and Canada frequencies. I do not live in USA nor in Canada. So is it possible to install an FM Radio application from Google PlayStore to get locale FM radio frequencies in my country ?

There is an related question on Stackoverflow: https://stackoverflow.com/questions/8559612 I would also suggest to read this article which explains the problems: https://github.com/mikereidis/androidfm/wiki/Creating-an-Android-FM-app

That really depends on if there is an app to stream stations from your country, unless you are talking about a real FM radio receiver function in the phone.
My s10e doesn't have an FM radio function, so the only way for me to get 'FM stations' is by streaming the station over the Internet with an app. I assume yours is the same. If not, read below. Carriers like to disable the FM radio to force you to use your data.
So if some company has built an app to stream stations like 'Iheartradio' in the US, then you can use it. Also, some US stations have websites that allow you to stream their station using a web browser. You might try that.
If you are talking about an actual FM rađio receiver app that uses 88Mhz to 108Mhz and your country doesn't use those frequencies, all I can tell you is you can try to find an app for your country. But if the radio in the phone is the US format, changing the app probably won't change the frequency capability of the hardware radio inside the phone.
As far as I know, the only areas that haven't switched to the 88-108Mhz band is Japan and Eastern Europe so Samsung may not make hardware specifically for your region.

Google account was hacked: how do I get my phone working with my new account?
My Google account was hacked, I think because somebody SIM-hacked my T-Mobile account. (Thus the Google account recovery process was short-circuited.) I've asked Google for help via the recovery process but I'm not at all hopeful. In the meantime (as the recovery process suggests!!!) I've got a new Google account.
Now I'd like to get my Android phone (ZTE Axon 7) working with the new account, but even after a factory reset it still wants to access the Google account it thinks is associated with the phone. In other words, from the "Let's get started" screen, it won't take my new account login, instead insisting that I provide the password to the former account.
Can anything be done to deal with this problem?

they claim it is working (i don't believe it) but give it a try http://www.teamgsmedge.com/2018/02/bypass-google-account-zte-axon-7-mini.html

@alecxs yes I saw that, I think ZTE patched the vulnerability that allowed the USB connection to work. Also that was for an Axon 7 Mini, not an Axon 7 (though I think the software is pretty similar).

Please see https://android.stackexchange.com/questions/127739/how-to-bypass-verify-your-account-factory-reset-protection

Possible duplicate of How to bypass "Verify your account" (Factory Reset Protection)

Please look for posts before asking another question

The hindsight version:
Factory reset protection is supposed to prevent thieves from stealing your phone and using it. To do this, the phone requires you to login with a Google account that was on the phone before the factory reset. Add the new account to the phone before the factory reset. Or, alternately, remove all accounts before the factory reset.

You cannot remove accounts without the account password.

When that happened to me, I had to flash the rom again. Some phones are protected against this, but it doesn't hurt to try.

That would probably work, but it's pretty drastic and I'm not sure how to do that on this particular phone.

Instructions for your device are here:
https://ztefirmware.com/zte-axon-7-a2017

Goto Settings option. In settings find Account option. Scroll through account option to find out the hacked account and remove it from the device. Then in the same menu, add a new Google account

SMS messages are coming slower after moving from S8+ to S10
Recently I moved from my Samsung Galaxy S8+ to Samsung Galaxy S10.
One thing that caught my attention is the time required for an SMS to arrive after being sent by a service that uses SMS messages to 2FA logins.
On S8+ the SMS would come about the same moment I click the button on the website. On S10 that process takes some three seconds.
Is that normal? Maybe S10 is a smaller device with less powerful hardware to talk with the provider. Maybe the same SIM card* that I have been using for the last six years needs to be replaced. Or such.
* This card originally came in the standard size. It had been cut down to the nano size.

Modern SIM cards are not only smaller but usually use different voltages. As you found out most Smartphones are backward compatible, however I strongly recommend to replace your SIM with a current one. I don't think the SIM card has an effect on the SMS reception, however SMS reception is done by the radio subsystem - a system that is mostly a black box. Therefore you never know what effect changing the SIM card has.

One reason i can think of is to combat SMS Bomber services... I imagine the device is actually doing a check for anymore incoming SMS that might be the exact same... The peeiod that it checks for another SMS sounds around 3 seconds.

what is the meaning of the output of the users list command
I'm using the cmd user list command and this is the output I'm getting from the shell.

UserInfo{0:Owner:13}
UserInfo{23:shalevM:20}

what does the last variable means? the first one is clearly the user's id and the second is the user's name, but the last one is changing from time to time and I don't know what does it mean.

The structure of the output is as follows:

UserInfo{id:name:flags}

Flags are basically bits of information describing the data model's level of access and/or permissions.
You can read some of the code comments on the flags defined in the UserInfo class here:
https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/content/pm/UserInfo.java

Why would it be changing... could that be a sign of changing permissions on the account ?

They most likely change as the user accepts/rejects permissions or other functional app settings because the value itself is a bitmask representing multiple data points in one integer value.

App not shown in Android app list
I am trying to install one app(updated version) but when I install it it says this app can not be installed because same kind of app is already installed but when I check apps on android phone I do not find that app of same name that I want to install as updated version.
I believe it is blocked by the user of the phone, (phone isn't mine now)
what should I do if the app is in the phone but invisible or blocked ,
how do I see it and uninstall it so that I install updated version on it.
kindly guide me what to do in this situation .
thanks and stay blessed

The app list on some device do not show all apps. Use an app like AppInspector to see the full list.

other application has the same package name

How do I make my kid’s Android phone ring even if silenced when I call him?
Sometimes my kids forget to put their phones on ring mode and then I can’t reach them. I’m looking for a solution that will unmute their Galaxy S7 when my or my wife call them.

you can send a voice note - 99% sure they will hear it within a minute ;)

especially when parents call their kids :D but they can not resist to click on play on any stupid voice note

"voice note"? I've never heard this term.

@SiXandSeven8ths lol i don't use WhatsApp but i am sure you know what i mean. It is that nice feature when they push the microphone button, speak, send a 00:02 / 2 MB *.opus file and bleed out their monthly data volume instead of typing "yes" in a sms text message

It might not be applicable if your kids are older, but my kid just got his first phone and I manage it with Google Family Link. Even when the phone is on silent I can make it play a sound and get him to answer a call or message. It's worked out really well for me, the one thing I don't know is if you can have more than one family device managers to manage the family's devices. It might be worth checking out at least.
I can also use it for managing screen time restrictions and other parental controls that I really felt were missing in cheap, stock Android phones.

I have Google family link and I see nowhere on the app where I can make his phone ring and on top of it now hes not listed under find my device (a separate Google app) now that I'm supervising his and so now we have no way to make his phone go iff so we can find the dang thing every time he loses it ..

"share via" doesnt pop up any appliction I choose
"share via" had been working for years, it stops to work a few days ago (i didnt update anything the last few days)
I click app "simple Gallery" -> choose a picture -> click "share via" ->  a list of apps I can choose (like viber, whatapps, mail ...) -> choose Viber (or some other) but nothing happens afterwards (no error, nothing. Just the picture)
But If i using the default camera -> display picture (it has its own viewer)  -> "share via" works
What can it be? "simple gallery" had been reinstall, reboot ...nothing help

Check the Android log for error messages. If there are errors there is a chance to understand what is going wrong and how to fix it.

Many thanks for the link, i use "logcat extreme" (catlink requires root, which i dont had). I tried twice, I cant see any permission issue, at the second try, there was "AppCompatDelegate:"?  05-30 17:21:10.266 17939 17956 I [MALI][Gralloc]: [+]r_hnd(0x7f8b470f00), client(32), share_fd(62)

sorry coudnt make End a line with two spaces to add a  linebreak"  this work :-(

the developer wrote: I expect you saved a default share setting for some app. This can be confusing to fix. You might try to install the free version and see if it works. If it does, then the default share setting got screwed up.

i wrote back: yes, default share settings, i did try to reset the default settings for ALL apps. i try reinstall S&R (send and reduced app)  several times with 2 different version, still issue

I developer ask me to reinstall the free version again....some magic thing happens,  "share" works again as it should.

sorry, it failed again few hours late. I discover at last "my smartphone policy" (may be me who click somtheing week ago) somehow disable 2 options for "send reduced" at permission -> other permission -> send & reduced. when you enable them and reinstall the app they got disable again. So now everything is ok again. Thanks Robert

"Mark all as read" in Messages... doesn't mark all as read?
I've asked the Microsoft Launcher to add a badge (unread message count) to the Messages app's icon
The badge always shows "34" even after I've done "Mark all as read" in the app.
Any clue as to how getting the count to 0 so that the badge disappears when I have no unread text messages?

What phone do you use (Phone model and Android version)? App icon badges with numbers are supported since Android 8. Some device are able to show them before 8 but these devices require a non-standardized way.

Oops... I must confess I didn't provide much information about my setup... My Nokia 7.1 phone runs Android One 9 with the Microsoft Launcher.

Unknown "________ would like to send a message to 45567" notification
I keep getting these random SMS permission notifications. The app or service requesting to send the message is always changing.

Pixel 2 XL on Android 9 on Freedom Mobile in Canada.
Play Protect and Malwarebytes don't detect any malicious apps.

How do I determine what's causing this?

Looks like this is an issue specific to Freedom Mobile users happening since May 9, 2019. Possibly caused by a software update from Freedom around that time, it appears to affect Google Phone (beta) users with Visual Voicemail enabled.

Background
There is a thread on Google's official support for Pixel Phone, which mentions the same issue about some multiple random processes requesting permission to send an SMS to 45567 on multiple setups:

Device model: Pixel 2, Pixel 2 XL, Pixel 3, Pixel 3 XL,
Android version: Pie, Q (beta)
Process name: com.android.sdm.plugin, Connectivity manager, Oemdmtrigger, com.qualcomm.data, uceShimService, Phone and Messaging St..., Modem Service, SDMService, [etc.]
Software update: After the May security patch, or after an update to "Carrier Services" and "Actions Services" but before the May security patch.

Temporary fix/workaround
As per Matthew Naugler Klassen's post, the (temporary) fix is to disable Visual Voicemail in Google's Phone app:

Open Phone app
Open Settings
Under Voicemail, disable Visual Voicemail

Additional Remarks
Freedom Mobile seems to aware and has acknowledged the issue, promising to escalate it and deliver the fix as soon as possible.

Block calls by area code but whitelist contacts
I've noticed a huge uptick in robo-calls using the same area code as my phone number. I no longer live in that area of the country, so I know that calls from this area code (that aren't in my contact list) are spam.
I've tried a few of the most popular call blocking apps, but have failed to find any that both let me block by area code and also let me whitelist the numbers in my contact list (so the people I know aren't blocked).
A user has asked a similar question here, but given the comment discussion below the answer, it seems that it no longer works.

I'd be interested in this as well, especially if I can also block by prefix. App recommendations are off-topic though.

Direct HDMI output at the start up?
I have an Android 6.0.1 Vibe P1 Turbo with literally dead screen(I closed the phone months ago and did a complete disassembly).
What I want to do is get the phone output the screen through USB right when it starts up. I was thinking about octopus micro USB with USB A legs and attach both a mouse and an "USB to HDMI converter" to connect it to the dumb LCD TV (1366X768 PAL) and backup data to the Google Drive and shut down the phone for good.
Will I be able to do it? Or I have to open the phone first which makes it impossible? Can you give me an things to have and a tutorial?
The phone has pattern lock

Is the device encrypted? Is a pattern/PIN/password set? Does it connect to Wifi if you boot it up? If yes, does the last seen date of the device in Google Play Store update?

Encrypted? I am not CIA the pattern is sadly sent (Altought the screen is really fucked up (Vertical streaks with more colors in a rainbow) I remember the touchscreen working so I guess I think I can open it. I completely disassembled the phone so I guess it will take some to reassemble it.

USB to HDMI converters require special driver. I never heard of an Android device supporting such a converter. The typical way to connect a Android device to a TV is using Wifi and screen cast technology.
There are some device that support MHL (re-use the USB-Port for a HDMI connection) but the number of device that support this is not very high and depends on the used chip in the phone. Anyway the USB port would be blocked in such a case and can't be used for USB devices.
Edit: Based on the additional info your provided (unlock possible, touch still works) the following may work:

Unlock the phone and connect it via USB to a PC. You should get access to your sd-card folder.
Use the screenshot feature to get the current screen content.
Open the screenshot on the connected PC
Try to tap on the position of the function you want to execute
Goto step 2

Using this you should be able to "use" your device in a very very basic way. Therefore what ever you want to to with it (e.g. exporting data)  might be possible this way.

Peh. looks like I got too used  to my good ole N8 with HDMI.

@Jonathan see my edit

thanks ! I never thought a comment could change so much things!

even though  my phone is such an asshole it has tendency not to show files sometimes and the volume and power buttons are ripped off in the cable level

Receive whatsapp notification only between a certain time
I want to receive all WhatsApp messages only between 11-12 p.m everyday.How to do this? Can tasker app help in this.Or a script which can be used. Also please note that only messages should be queued but video/audio calls should function all day.

you can disable notifications for 1 Hour/1-day etc. through WhatsApp Web. Check more details at the official Whatsappp FAQ here https://faq.whatsapp.com/en/web/26000051/?category=5245251

WhatsApp messages could not be stopped while they are coming from the app's data system.

In other words, we can't stop WhatsApp from receiving new messages while we have an active internet connection.

One possible solution could be blocking the "New Messages" notifications coming from the WhatsApp application. Maybe, we will require some code to do this but it is yet possible.

WhatsApp send notifications to alert the users regarding new messages. We could intercept these messages and block them for some time interval and also store them for later.

If the user can see notifications only in a specific interval of time, then we only know that new messages have arrived only at that specific time interval.
Hope this helps.

Thanks.But how to achieve this!!

You will need an app coded specifically to do this. Maybe, you can find one on the Play Store. This app might help -> https://play.google.com/store/apps/details?id=net.mready.zenty

Can easily be done by intercepting the notifications during the desired timeframe with the AutoNotifications plugin, and making any action (such as 'dismiss') to achieve this.

How to allow an app to take screenshots automatically?
How can I allow an app to automatically take screenshot?
I'm not talking about apps disabling screenshots on them, I can take screenshot of the thing manually, but I'd like to automate it. I use the app Automate, which has a screenshot action, but when I run it, a dialog appears asking me if I want to allow the app to see everything what is on screen, and that happens every time. I basically want to autoapprove this dialog.
Is there a way to do that?
Thanks

MacroDroid can do it, but requires root access. Autoinput app (root not needed) also has this feature but I couldn't make it work.

I think Auto Input takes advantage of the ADB over Network feature... It initiates an ADB Connection via the Local Host 127.0.0.1 ... This Feature has been removed for security concerns...

OK, so I got one possible workaround: use the Automate interact touch block to click on the confirmation button, like in this flow:

Is it possible to play .3gp videos in browser on Android?
I am not able to play .3gp videos with Google Chrome nor Firefox on Android.
Chrome plays the video without image, only sound. And Firefox asks me directly to download the video.
I wonder if there is a way I can watch the video first in the browser, like a .mp4 video. Is it possible?

Which device/OS version do you have?

It's a LNMBBS tablet with Android 7. But I tried with other devices with Android 8 and it's the same thing.

3GP is just a container format - what encoding is used by the video? May be your device just don't support the codec used by the specific video you used for testing.

The device plays the video in its gallery and other media players without problem. Codecs: MPEG-4 Video, AAC.

Why does my Samsung Galaxy S8 Active no longer "Fast-Charge"?
I bought a refurbished Samsung Galaxy S8 Active in excellent condition about 6 months ago, and it came with the standard manufacturer-provided power adapter and cable for charging (Model: EP-TA20JBE, labeled "Adaptive Fast Charging"). For the first 5 months it charged without problems - Fast Charging was available virtually every time I plugged in the phone and my battery typically charged from less than 20 to 100% in about 90 minutes.
In just the last few weeks though, charge speed seems to have diminished significantly, and my phone never indicates Fast Charging anymore after being plugged in, only Slow Charging, which variably estimates 4-6 hours to reach 100% from less than 20%. I've used the same cable and adapter the entire time and haven't adjusted any software settings. It seems as if this original cable and/or adapter have simply crapped out, for no apparent reason. Occasionally, I'll plug in my phone before falling asleep at night, Slow Charging is shown, but when I wake up 6 or 7 hours later the battery has gained only 1 or 2% charge (or sometimes none at all) even though the cable remains plugged in and the icon still indicates that the phone is charging.
I did a bit of forum searching on other sites and learned that the manufacturer-provided cables and/or adapters can age very quickly or otherwise be unreliable. I bought a new cable and adapter of the same type, but made by a third party, and tested it: no luck. Neither the replacement cable nor the adapter, together or in combination with either the original cable or adapter, seems to improve the charging speed.
I'm still committed to the notion that the problem lies with the cable or the adapter rather than the battery itself, since I've noticed nothing unusual about the battery's lifespan or other activity in any way - there's no excess heat either when plugged in or not; battery life is nearly as long as it was 6 months ago when I first bought the phone; I never use the phone for any games or movies or other battery-intensive apps, just Internet browsing and basic communications. Observing the circumstances as empirically as I can manage, charging speed seems to be the only difficulty. But I'm at a loss to explain why.
Should I trust the perception that the cable/adapter combination is at fault? Is it preferable to purchase a cable or adapter from Samsung that is identical to the one I'm using now, rather than one of the many third-party options? How can I regain Fast Charging ability - or, at the very least, the peace of mind to know that when I fall asleep, I'll wake up to a fully charged phone? I appreciate any insight you can provide!

TWRP 3.3.0 cannot decrypt data partition (of Android 9)
I just updated to TWRP 3.3.0 from older PitchBlackTWRP but now TWRP does not ask for the password any more. Tried manually decrypting and manually wiping from TWRP terminal. Did not help.
recovery --wipe_data
twrp decrypt <your password>

How does Android encryption work? Does TWRP need except the password some device key?
Booting the system still works fine, so still everything is available what's needed for decryption.
Yes, I saw TWRP OnePlus 5T not asking for encryption password , but the solution did not help. And I am not allowed to comment.
Should I reinstall PitchBlack-TWRP?
ps. I don't need the data, did a backup before.

Well, sorry for bothering. The solution was simple: Don't use the wipe function of TWRP but the Format Data button in the wipe menu.
I was able to factory reset and install a different custom rom.
BTW: Don't use TWRP for Android >= 9 (Pie). As of Version 3.3.0 TWRP lacks the vendor partition feature. Pitchblack seems to be the standard now.
Edit: I think the problem is: Android 9 introduced the quota feature of the ext4 filesystem. TWRP doesn't know about it yet.

Salvage app cache when unable to open app
Every time my phone reboots and sometimes even without reboot when it's working at I guess full capacity, it resets its settings and acts like I just booted the phone for the first time except from all the apps I've installed (i.e. non system apps) still being installed. However, I cannot open any non-preinstalled app as they just close immediately when I open them. Deleting the cache and/or force stopping the app doesn't help.
Since my last WhatsApp backup file msgstore.db.crypt12 is a couple days old, I tried to "rescue" the WhatsApp cache since the msgstore.db is just a backup file and WhatsApp stores the messages "live" in a different database that doesn't seem to be accessible without root (and I cannot root my phone at the moment).
The WhatsApp app-info shows that WhatsApp actually still occupies a lot of cache data and app data and the WhatsApp symbol on my application overview still shows the number of unread messages I had before the last unwanted reset.
I already tried backing up the whole app with as much app data as possible via adb with adb backup C:\wabackup.ab -apk -obb -shared com.whatsapp, uninstalling WhatsApp, reinstalling it and then restoring the backup but running the app afterwards just prompts me with the screen I would usually get when running the app for the first time after the installation.
The WhatsApp folder seems to be totally fine but maybe it's a permission issue with the folder. ( How to manually transfer entire Whatsapp installation to another device (the hard way) )
I would really like to fix this, not only for WhatsApp but also for other more important apps like banking-apps and 2-factor-authentication-apps that of course encounter the same problem at the moment but unfortunately I am not too familiar with the way Android stores app data.
This is pretty annoying obviously and I have already ordered a new phone. I am currently using the SM-J510FN.

Take a moment and make question shorter, nobody is going to read this much text, trust me. Since you are mentioning cache, I don't think that is where backups are stored, since it easily can be deleted. Don't WhatsApp have online backups?

@ЈеднорукиКрстивоје Fair point, gonna shorten the question in a couple minutes. Yes, WhatsApp supports online backups but this feature just regularly uploads the most recent msgstore.db.crypt12 into the cloud and since this file is too old, restoring from the cloud doesn't fix the problem in my case

AR Core OnePlus 3T
Recently, I reset my OnePlus 3T settings. So, after that, it says that my phone doesn't support AR. But it worked before and this phone in the list of supported devices.
Ar Core version - 1.9.190422056 - the newest.

might be silly suggestion.. but did u try installing google arcore https://play.google.com/store/apps/details?id=com.google.ar.core

Just install ARCore by Google

ARCore is Google's platform for building augmented-reality experiences.

If it still doesn't work, try first to restart the phone. Then if you still have the error message try some alternative AR applications like Measure.

So, as I investigated - OnePlus 3T just is not supported in version 1.9, so I deleted ArCore apk-file and in my dependencies in Gradle set 1.8 version. After that installed version 1.8  of ArCore

Frequent contacts disappeared
I have a Moto G5 with Android 7.0 and Phone 3.00.00.
It used to be the case that when I called one of my contacts, they would appear in the "Speed dial" tab of the phone app, just after my favorite contacts.  For some reason, my phone app's speed dial tab doesn't show any frequent contacts any more.  Only favorite contacts appear.  The call history tab still shows these calls, so I am using that for now.
Do NOT ask me to look for a "Show frequently contacted" setting.  I have checked both the phone app's settings and the contact app's settings and I don't see a setting for "Show frequently contacted" which seems to be a Samsung setting.

samsung setting? moto is stock android and samsung is custom ui. please reply with your current phone app version in moto. speed dial shows starred contacts first, scroll down to view dialled numbers in speed dial.

@RahulGopi thanks for your comment.  I have edited the question with the phone app version, as well as the reason for mentioning the samsung setting.  Speed dial ONLY shows starred/favorite contacts (as I said), and I only have two, so there's not enough contacts to scroll.

I don't receive text messages on time
Using a Samsung Galaxy S7,
When someone send me a text message (sms), I often receive it several tens of minutes late, sometimes even a few hours late.
For instance:
Other: - We're going to the cinema tonight, wanna join?*
Other: - Come on join us!
Me: - Where?

*For instance I receive this message 1 hours later so this is kinda annoying.
I first suspected a contact failure of my sim card but it doesn't seem to me that this is the case

Are you sure you are talking about SMS and not some 3rd party instant messenger? Your mobile network operator is responsible for SMS. You can verify this by using a different phone, it should not have an effect on the delivery time of your SMS.

Yes, I'm actually talking about sms.

Are you using a 3rd party SMS app just in case?

@singhnsk I tried both samsung default messaging app and google's one. If I can provide more details I'll be glad to help.

How do I set up erase and secure?
My phone was stolen so I tried to erase from Samsung Device Manager but it just sends an erase instruction which I don't know whether the person who turns my phone on will be able to just stop from the device or not :(
Also the erase button on google device which sends a notification to the stolen phone to set up, the friendly thief ;)
So I'm trying to not be in the same position again, I don't understand how to set up erase and secure from my new device.
Please help, Thanks

Remotely find, lock, or erase an Android device:

Go to android.com/find and sign in to your Google Account.

If you have more than one device, click the lost device at the top of
the screen.
If your lost device has more than one user profile, sign in with a
Google Account that's on the main profile. Learn about user profiles.

The lost device gets a notification.
On the map, see about where the device is.

The location is approximate and might not be accurate.
If your device can't be found, you'll see its last known location, if
available.

Pick what you want to do. If needed, first click Enable lock & erase.

Play sound
Rings your device at full volume for 5 minutes, even if it's set to
silent or vibrate
Lock
Locks your device with your PIN, pattern, or password. If you don't have a lock, you can set one. To help someone return your device to you, you can add a message or phone number to the lock screen.
Erase
Permanently deletes all data on your device (but might not delete SD cards). After you erase, Find My Device won't work on the device.
Important: If you find your device after erasing, you'll likely need your Google Account password to use it again. Learn about device protection.

More informations: support.google.com

Thank you I've done that but I was more concerned that a) it will only erase if the phone is turned on within the next year and if the thief turns it on will they be able to stop the erase from the device. Also b) how to set it up on my new device to gain more control in the event it ever happens again.

Strange status bar icon on Samsung devices after using Developer Options
I have a Samsung Galaxy S8 phone running Android 8.
I have enabled Developer Options today and after I finished with it, I disabled it again.
The problem is that a strange icon has left on the status bar. This icon appeared immediately after I enabled Developer Options.
Here is a screen of it.
What's this icon and how can I hide it?
Thank you very much for your help.

The icon appears to be for when the device is locked to "Portrait" mode. Or in simpler terms, when screen rotation is turned off.
It is most likely inbuilt into the phone and was there before. In case it wasn't, you can disable it from the SystemUI tuner.
Simply tap and hold on the gear (settings) icon which you see when the notifications bar is pulled down. That will enable the SystemUI tuner. In there, select status bar and disable the icon for Auto-rotate screen.

Huawei update to EMUI 9 broke everything
I have a Huawei NOVA 2S which I purchased in China.
I got the EMUI 9 update yesterday and none of my Google Apps were working.
Found this: https://itechify.com/2019/04/26/fix-google-apps-on-huawei-after-emui-9-update/, which is exactly the problem I'm having but those steps don't help.  I ran the GMS installer 1.2 and it removed all google apps.
I then installed Google play services (17.1.22 version code: 17122012).  I keep getting "Google Play Services won't run unless you update Google Play Services".  This is the most current version!!
Another Problem: I downloaded and installed Chrome from the Chinese app store.  It opens for a minute then crashes.
I can't even get the Play Store to work at all.  I installed the most current version for my architecture from apkmirror.com but it won't work.  It just crashes instantly on opening.
Any suggestions other than use as a paperweight?

I had to rollback to EMUI 8.0.  This was easier than expected through the HiSuite Huawei app for PC.  Click on update/upgrade, then other versions.  It should show you the last version and then click restore.
I then ran GMS installer, and Google-installer-v2 and I'm back in business!  I am still getting "Google Play Services won't run unless you update Google Play Services" occasionally but everything works.
