Cannot use O2 rewards on Play Store; got error code OR-RCP-01
Tried to use O2 rewards to buy something on Play Store but I can't as I need to enable it (add O2 billing?). But every time I try to put it on, I get the error code [OR-RCP-01].
How do I get this to work?

Welcome to a Q&A site Android Enthusiasts Stack Exchange. I tried googling about using O2 rewards on Play Store, but I didn't get any convincing results. Just to confirm, are you sure it's possible to use it directly on Play Store, instead of redeeming it from another app like Priority: Gig Tickets & Perks?

Block app from playing audio in the background (for productivity)
I find myself easily wasting hours on social media and listening to podcasts. I now use apps that can be configured to block certain apps and certain websites at certain times of the day. These are called "digital well-being" apps or productivity apps. I'm currently using Stay Focussed. However, it doesn't stop me from using the player in Android's notifications area to play podcasts.

(Illustration from here)
Is there a way to block certain audio apps from playing? Is there an app that does this? I want to block podcast apps completely at certain times of the day, even when I'm only accessing them from the audio notification panel.

Delay text selection mode after touch
When a text is displayed e.g. in Chrome, you can switch to text selection mode with a long-press.
I often enter this mode accidentally when I only want to scroll slowly. I tend to scroll continuously while reading long texts.
Is there a setting to prevent this? Can I increase the delay before a long-press causes text selection mode, or increase the threshold so that even a very slow scrolling motion is detected as scrolling?
Can I somehow disable text selection entirely for specific apps?
I tried changing "accessibility / timing controls / touch and hold delay" but that did not appear to change anything. It is currently back to "short"
The problem occurs in various applications that allow scrolling as well as selecting text: Chrome, Firefox, Lithium.

Android active DnD when listening to bluetooth music in car
I'm on Android 13.The issue I'm having seems to have started after the last security updates. I listen to Spotify in my car. Now I see that DnD is turned on when the car is connected via bluetooth to my phone (Pixel 4a). The car does not have Android Auto. It is an older Mazda 3 from 2010.
I have looked at the settings in Spotify and the phone, but cannot see anything that could prevent this from happening.
Even if I manually turn off DnD, it sometimes gets activated again later. Very annoying.
Any suggesting of what to do?

Welcome to the Q&A site Android Enthusiasts Stack Exchange. Have you checked the Do Not Disturb setting on the phone, particularly under Schedules - Driving - Turn on automatically? It has "When connected to Bluetooth" and "When driving is detected" as some of the triggers.

Turn off the screen overlay
I have installed Moon Reader Pro on my ONYX BOOX MAX 3. Got message while run and setup Moon Reader The reader needs Storage Permission to manage book files. After allowing this permission I got another message:
Screen overlay detected

To change this permission setting, you first have to turn off the screen overlay from Settings>Apps

Open Settings

After opining settings I got list of applications, but there is no Moon Reader in the list.  Without this perdition it is not possible even reed books. How to solve this problem?

Please follow the link to the duplicate Q&A. You have to temporarily close apps/turn off features that use screen overlay, which I believe Moon Reader Pro is not one of them.

The phone died suddenly, no lights, no beeps, no logos, no charging - bricked completely. Any ideas or strategies that might unbrick it?
I know it is out of its prime days but elegant and reasonably sized.
Already tried

left charging overnight
click vol up down in the same time, vol down and start in the same time
tried other cables/outlets/chargers

UPDATE: I was able to produce solid red dot with by pressing first vol up and down and then start. I found an recipe on internet, but it had dead link to miflash tool, I can find alternative miflash download  with google search though not sure which version is more legit/efficient
UPDATE 2: somehow was able to reboot, seems to work, yet is suspiciously hot, not sure may be I should uninstall some apps or reset to factory

S9 died black screen cell gone but I need to decrypt my SD card- Help!
My S9 black screen death, now GONE. TMobile replaced now I have a Moto G5 android. It does see the files but does not open. I have encrypted my SD card not aware I had to decrypt from my S9 but now I can't. I have copied all information from SD card to my Win 11 pc just to have safety I hope. I've been Googling for an answer but all confused on what to do...?
So many softwares to get me to buy, don't know if it will work or any other paths to do.
Really appreciate any feedback please!

If you can not access the sd-card the card was formatted as internal storage? If yes the necessary encryption key is stored within the flash memory of your phone (also encrypted by the lock screen pin/password and the gate keeper. So if the phone dies the data on the sd-card are gone.

Unexplained Bluetooth notification upon disconnecting
Pixel 6a, Android 13 (July update) was connected to Jabra Elite 65T and I experienced this weird and inexplicable notification

On disconnecting the BT, this notification appeared:

On tapping it, it turns out to be the previously paired Jabra but showing it as unknown.

This was very strange because:

Jabra BT was given the permissions the first time it was paired and never asked for them ever. I've been getting calls with contact names read out too.

I didn't receive/approve any other BT paring request ever.

This notification appeared only after disconnecting and not on connecting

Just to rule out the unlikely event of another BT device possibly somehow getting connected,and asking for phone book access, I again connected & disconnected to see the notification yet again. This has never happened in the past AFAIK. Also in BT connections no other device was showing up

I am trying to understand why this happened but can't think of any reason neither does a Google search help.
Can someone please explain how the Jabra device shows up as "unknown" and ask for previously approved phone book access?

You need to do some more tests

Creating a backup partition on Android
It would be lovely if I could manually  allocate a portion of space to create a partition for backup that's separated from the other partions that gets wiped or replaced when flashing a custom rom so for example as root if I can create /dev/sda99
Mount it backup the custom rom and other files and in twrp recovery I can mount it again and flash the custom rom and the backup and it doesn't get wiped when I format the data in twrp.
But I don't know if it's even possible.
This is a list of my partition

I know must of Android uses mmcblk as reference for all the partions but the layout on my device is different I don't know why.
As you can see the bootloader abl and the recovery are on separated block sde
userdata and super partion are on sda block so if were to use parted on /dev/block/sda to create a partition, is it safe ? Is it going to have an impact on recovery and bootloader? is it even possible to allocate memory without shrinking other partions?
Overall it seems like a risky process but it's worth it

How to Avoid My Video Being Cut to 10 Seconds When Posted to Instagram Stories?
I learnt that since late Sep 2022, the duration of IG stories has increased from 15 seconds to 60 seconds. However, today when I tried to post a 25-second video to Instagram Stories in my Android phone (actually the video was an MP4 converted from a still picture using ffmpeg, because there are words in the picture I would like viewers to have enough time to read), added music to it (Instagram also showed 25 seconds in this step but the number was greyed) and then published the story, the published story became 10 seconds only (not even the old limit of 15 seconds).
I tried a few times but the result was still the same. I searched the Internet but seems no one mentioned a similar problem. What steps do I have to do in order to make sure the video (and the music) can last for 25 seconds? Did Instagram detect my video was actually a still picture so it treated it as a photo?

Emails with attachments are getting queued by Gmail app
I am facing this issue with the Gmail app, where the emails without attachments are going through, but the one where I attach something like a pic stored on the mobile, the email gets stuck in the Outbox.
But I can send emails with attachments through the web browser.
Things I've tried:

Uninstalled and installed the Gmail app again
Updated the apps
Clear cache + clear data + restart phone

None of them works.
The Permissions page shows Files and Media under the Allowed section, so the permissions should be fine.
Not sure what else I could try.

How can I change the installation directory in Orange Pi from internal storage to external storage running
I am running android Operating Software in Orange Pi. How can I change the installation directory from internal storage to external storage (SD Card). As my application file size is 1gb ++, the internal storage of Orange Pi is only left with 1gb. So, the storage is not enough. Can anyone help me?

Experts can clarify better but when the OS boots, it looks for files in the internal storage, does it's checks and at a much later stage the ext.SD comes into play. Ext.SD is only meant for storage of media, not designed to boot OS (unlike PCs where you can boot into the OS available on flash USB drive)//You can read more in the answers here

How to rename and modify ethernet interface in Android during runtime?
I have an Android emulator based on Android Pie running in a Docker container. Docker by default assigns eth0 interface, we use the eth0 IP assigned by Docker and write it to ipconfig.txt (/data/misc/ethernet/ipconfig.txt) to let Android use an ethernet tracker to track the eth0 interface, which happens during the boot up phase.
We want to create a new ethernet interface for certain apps to enable some sort of tunneling. As part of that, we are trying to rename existing eth0 to eth1 and create GRE-enabled eth0. In terms of IP link, I tried the following commands after the emulator completed the boot-up:
ip link set eth0 down && ip link set eth0 name eth1 && ip link set eth1 up
ip link add eth0 type gretap remote 10.0.0.1 local $ETH1_IP dev eth1
ip addr add 172.18.0.2/24 dev eth0
ip link set eth0 up
ifconfig eth0 mtu 1368

After doing the above renaming, the emulator doesn't have network connectivity, unless we specifically specify the interface name like ping -I eth0 8.8.8.8.
My understanding is whenever we make any changes to the ethernet interface using ip link commands, Android listens to NETLINK and processes these updates, so we don't need to do anything extra for this to work.

Get a list of unreadable files using ADB
I'm trying to make a backup of a dying SD card on my Samsung Galaxy Note 8.
I tried using adb pull, better-adb-sync, and other tools. The problem is that, not all files are readable because of the bad state of the SD card. Right now, I have been copying each file name that failed and putting it in a exclude list, but this is extremely inefficient and frustrating.
I wish there was a way to get a list of files that fail to be read, put them on a file, and then do a proper pull of the rest of the files.

I opted to use a script that reads a list of files and copies each file one by one, letting the ones that fail... well, fail, and then continue with the next:
DEST="$(pwd)/Camera/"
for f in $(cat all-files.txt); do
    echo "Processing $f"
    adb pull $f $DEST
done

I will still love to know how can I "test" each file to know if it is readable or not, just to have a list of corrupted files.

For testing if a file is readable I would avoid adb and directly execute commands inside an adb shell on device side. Not sure which command is best to check if a file is readable, but standard Linux tools like find (in combination with -exec parameter), grep -R or shasum may output if a file is not readable.

Valid sim card occasionally not being detected
My android (TLC 767w) Will occasionally lose all network access, reporting an error that sim card could not be detected and giving an annoying ping every minute or so at me.  I've always been able to get the phone to detect the sim card eventually, but I'm worried it may be a problem that will grow worse or strand me at an inconvenient time without access.   So far the issues have only happened when roaming out of my home state.  I couldn't imagine why my physical location would matter for detecting the sim card and so presumed the fact that it always happened out of state was a fluke, but the last two times in particular seemed suspiciously (in)convenient timing if location didn't matter so not sure what to think now.
I've tried looking up causes for sim card errors and none of them seemed to help.  I checking and cleaning the physical sim card, not really sure how much that would help.  I've tried changing network status, resetting network and connecting to one manually etc without help.  I hadn't made any noticeable changes to third party apps around the time the error appeared so I don't think that is the cause of the problem.
A bit more detail on each time this happened.

First time was many states away.  Issue persisted for days and after I returned home, which was when I realized it was a sim card issue and not just being out of network.  A reboot immediately fixed it but only after it stayed broken after I went home.
(I tweaked some network settings trying to figure out cause of networking issue this first time, not sure if that matters)

Second time reboot fixed the problem while still many states away.

Third time an 1.5 hr north of my home.  The 'reboot' option didn't fix it, but shutting down phone, waiting a few minutes for all capacitors to drain, and then rebooting did.

Fourth and fifth times a month later on same trip as third time.  Lost network connection at roughly the same point in the drive.  Repeated reboots of any type didn't fix it, but the network did seem to come back on its own eventually as I drove back towards my home state without a reboot.  This seemed really odd, it stayed broken for hours away from my home and fixed itself only as I approached home...

It may or may not have happened one other time very close to my home.  I lost network connection where I know I should have had it, but never got the error message about being unable to detect the sim card.  I probably should have waited longer to see if the error showed up (it always seems to take a bit for the error to be reported, I waited as long as it usually took for the error to appear at least) but I was in a hurry so rebooted the phone and network connection came back.

So yeah not sure what to do next.  I'm trying to figure out the likely causes, if I can do anything to minimize the problem and/or if I should expect it to grow worse over time, and rather a replacement of my android is likely to help or be necessary.

How old is the used SIM card? Ich you look at the contact pads of the sim card are there deep scratches visible that could prevent electrical contact?

Data transmitted via ADB makes emulator stopping
Recently, I was running the Visual Studio Android emulator and TCPView, and I saw that the emulator keeps stopping.

When I click "Wait", then some data is sent via adb to the emulator and the same amount of data comes back via adb on another connection.
When I click "Stop app", then data is transmitted without stopping.

Then I stopped the VM and reset it where it started from the beginning.

Disable MIUI automatic updates setting on each reboot
I have a Xiaomi Redmi smartphone, and looking for a way to perform the following task on each boot or every day:

Settings - System app updates - Settings - Automatic updates - Disable automatic updates

MIUI does turn system app updates back on, quite frequently. My banking application doesn't like rooting, and I'd like to avoid the hassle anyways.
The application I am looking for would be the MIUI/Android equivalent of "O&O ShutUp10++" for Windows. This application disables Windows Updates every time the OS decides to turn it back on.
Please let me know if you can find a way to do it.

"Unspecified error" when using external SD as root for KSWEB web server
After installing KSWEB web server on an Android tablet, everything worked fine out of the box.
The problem started when I realized I needed the web server root to be in an external SD card as there was not enough free space left in the internal storage. By default, the host configuration file points docroot to /storage/emulated/0/htdocs (port 8000); this is somewhere in the internal storage and works perfectly.
The path of the folder I want to use as the website root is /storage/826C-1AEF/htdocs (I got this address from the folder's properties); however, when I point the Apache server to this location, it finds it but I get an "unspecified error" which prevents the Apache service from starting.
I understand emulated/0 is some kind of link effectively pointing at the htdocs folder, located in internal storage; there is obviously an error in the way I specify the new path to external storage; is there a different "emulate" for external storage, for it certainly didn't like the direct path?
Can anyone see my mistake?

KSWeb bases on apache, which is a native application. As far as I know on unrooted devices an external card is only accessible using the Android Java API, not via standard C file API.

I'm on a vortex android 13 phone and the developer app disappeared on me. How do I get it back
I'm on a vortex android 13 phone and I just got the developer installed and I'm not sure what happened but all of a sudden the developer disappeared and when I went to install it again it won't let me. I tap on on the right area and nothing happens now. Nothing at all happens when I tap the build number.i need help to find it and to get it back without doing a factory reset because I have a lot of data on my phone that I really want to keep. Help me someone please.

Welcome to a Q&A site Android Enthusiasts Stack Exchange. By "vortex android 13 phone", did you mean Vortex Cellular? That said, developer options are not usually "installed", but only "enabled" by tapping the build number 7 times. Could you explain how did you install it before?

What has happened with text emoticons in Google Keyboard
tl;dr Despite my settings and my movements (using text-only emoticons) Google Keyboard in my phone (realme GT 5G) keeps "throwing" graphical emoticons at me everywhere.
Is this a bug (introduced in Android 13, to which my phone was updated to yesterday) or Google policy to make using text-only emoticons as hard as possible? Is there anything I can do about this?

Today I have noticed a very weird behavior of my Google Keyboard. Somebody or something is trying to force me to use graphical emoticons (which I personally hate) and to make using text ones (which I favor) as hard as possible.
First of all, even though I am using text-only emoticons, each time I long-press emoticons button to open emoticons bar, I see the graphic ones:

In other words the above screenshots shows that Google Keyboard claims that it shows me recently used emoticons (the clock icon checked), but this turns out to be not true. Because all the time I see emoticons that I haven't been using for ages (some of them -- never).
Being force to switch to text tab each time I want to paste a text emoticon sounds like a madness.
Second of all, I have checked a configuration switch to have additional bar with recently used emoticons shown directly in keyboard. And, again, I am all the time presented with graphical emoticons only. That I was supposedly used recently. Even though (as you can clearly see below) I am again using text-only emoticons.

My phone was updated to Android 13 yesterday and I have noticed this weird (to me) behaviour this morning. Could these two things stand in common?
Can someone replicate the above described problem? Is this a bug or some recent "change in policy"? Maybe someone at Google or Android dev team hates text-only emoticons? And they've decided to make using them as hard as possible.

how to playback same mp3/audio file in a loop with reduced playback speed
I have downloaded a bunch of audio files. Sometimes I need to play an individual file in a loop several times, with a slower speed, e.g. 0.8. At the moment I use Google Files, I open Downloads folder, I double click on a file to play and then I can change speed to 0.8 or 0.5 from the three dot menu. However if I fail to restart file fast, the player jumps to the next audio file.
I imagine that creating a separate subfolder for each file may help, but wonder are there any better solutions? I tried a couple of random audio players but did not find features I want.

Run a root script using Magisk mount space
There are many questions on this site about running a root script but none using Magisk mount space.
I have a Pixel 6a and came across this post (65)  in a thread dedicated to improve the speaker output. The developer posted a Magisk module which works fine but the post linked appears to be an improvement since one can vary the output on the fly. That's the reason I want to try that but I don't understand a thing about Magisk mount space and how to use that to run boot scripts.
I tried using Magisk Manager and Fox Manager but was unsuccessful as I expected it to be since it's not a Magisk module. On extracting the zip file, you get a shell script and a template having mixer configurations.
While I asked the poster on how to go about it and am yet to get a reply I believe I can get better answers here.
So, how do I run it? Please be detailed in your answer as I am
not at all conversant with this.
Unsuccessful attempts:

Set mount name space mode to "Global" in Magisk settings.

Imported the script in three kernel managers, rebooted, no output.

Repeated step above with su - mm in the first line of script. No luck

Imported zip file contents to Termux downloads, made them executable and ran ~/downloads $ su -mm && Audio_Mixer_Changer.sh no output

Android 9 keeps shutting my browser tabs on Other User when I just switch to other apps
I use Kiwi Browser, tried Lemur Browser but they all do it, it's so frustrating cause not only that it refreshes tabs but it shuts them off completely and just when I come back to it it leaves a blank tab open, nothing from my old stuff.
This is on my Other User, where I also don't have Recent Apps shown so I can't just open the browser where I left off.

Your problem could be unrelated to user switching - it could be a RAM problem: your system may be too old and has too little RAM to keep two instances of a large web browser alive.

Run script when android off

If a phone is shut down it can't execute anything. A few devices may have an autonomous subsystem for timer based actions, but those chips are usually not programmable in a general way, it is more executing pre-defined actions at certain times like creating an alarm sound or starting the phone.

How can I get my galaxy 4 watch to show on google maps?
I have a Samsung Galaxy Watch 4 40mm watch with LTE for my son.  I had to use an old galaxy phone to set it up, since I wanted it to be associated with his accounts completely separate from mine (basically samsung and google accounts).  But after that, it seems to be self-sufficient for the most part, i.e. we can text and call without the phone even being on.
I don't want to rely on the phone at all for this watch, unless we need to reset it or change a specific configuration.  I want my son to be able to effectively use it for calls, texts, and GPS location.  It's this last part that I can't figure out.  He has a google account and its configured on the watch and the Location Services are on, but I cannot see his watch from any apps.  Google Maps doesn't show his location, despite location sharing being on + configured to share with me too.  Thus, I don't know how to find the watch's location aside from using the phone that it is paired with, which like I said, I don't want to rely on.
Are there some apps or other configurations that can allow me to see where this watch's locations at all times?

getevent not reporting taps
I'm trying to automate some tests on a Pixel 5a (Android 13).  To do so, I need to tap on several buttons.  I've been running adb shell uiautomator dump to get the pixel locations of the buttons.  However, there's this one button which is clearly visible on the lower right hand corner which the XML dump reports has a location of (0, 0).  That didn't seem right (and running adb shell input tap 0 0 predictably did nothing) so I ran
adb shell getevent -l

to see the pixel location as I tapped it manually.  However, no events of any kind were displayed as I tapped all over the screen.  Instead, I saw

Bluetooth transmitter function working on an Android device
I have a Bluetooth transmitter and receiver, and would like to get the transmitter function working on an Android device, with the idea being an audio input into the transmitter end gets output on the device end wirelessly.
The manual of that device shows that the TX works under something called SBC and aptX.
Is there a way to have an android device be considered as SBC, aptX, or its variants?

SBC and aptX are just names of audio codecs. SBC is the standard Bluetooth audio codec supported by all Android devices and aptX is a proprietary codec with better quepality supported by some Android devices. Your main problem is that usually Android only sends Bluetooth Audio. Not sure if an app can receive Bluetooth Audio traffic.

Automate inserting 2FA code when screen is locked
I use a service for which I'm forced to use two-factor authentication whenever I log in. It's pretty inconvenient and unnecessary, so I would like to automate accepting the authentication request when it arrives on my phone.
The service uses an Android app that sends a notification when an authentication request arrives. When I then open the app, I need to insert a 4-digit PIN code which accepts the request.
I tried using an automation app (MacroDroid) to open the 2FA app whenever it sends a notification and simulates the four clicks. However, this only works when the phone is unlocked, and as far as I understand, I will run into this problem with any automation app.
The goal is to accept any authentication request without having to interact with my phone. Is there a way to insert the code without unlocking my screen? Would I have to root it? Or do I just have to keep my phone permanently unlocked?

As far as I know, this is not possible. I would go an alternate route. Install an android emulator on a pc, install the 2FA automation there, and just keep that running. Do note that bypassing 2FA is very insecure and is definitely not recommended. I would complain about it and see if you either can get extempted from the service side, or that they allow some kind of caching, such that you only have to accept it every x days.

Installing a 2FA on a desktop doesn’t require an Android emulator provided its not Okta Verify, since that particular 2FA, is special

I have automated this by using WinAuth. Once the QR auth is fed, it supports using a shortcut key to enter Auth PIN on any text field. Very handy and I am able to login at 2FA sites/applications in a jiffy with this

Hi Arvind, its too succinct for mosr people. Prrhaps you could edit it and expand it.

Looks like this is a Windows app, not an Android app. Did you mean to supplement the suggestion in the comment thread on the question regarding "using an Android emulator on a PC"? Otherwise, could you [edit] and expand on how to achieve this with an Android device?

Repeat calendar reminders until dismissed
I want appointment reminders from Google Calendar appointments, hopefully allowing different sounds for different calendars, but for sure playing the sound whenever the Google Calendar reminder is set for, and until dismissed.  But my phone isn't glued to me, nor am I to it.  I might or might not have it with me outside.  I don't hear it in the shower.  I don't rush back to it to see if I missed something.  One little ding doesn't do it for me.
My Galaxy S5 worked for me.  I had CalenGoo set to repeat reminders every 5 minutes.
My Pixel 3 XL doesn't.  CalenGoo is set up just the same, but Android 12 only occasionally plays the sound.  Might play it hours late, or not at all, even with the battery saver turned off.  One issue apparently is if I haven't opened an app for N days, the notifications just stop.  It's an issue for me for both CalenGoo and WhatsApp.  I usually use the computer, not the phone.  But even if I remember to poke the app and keep the battery saver off, the reminders still usually just don't.
I tried 'Repeat Reminder Plus', but it presumes as soon as I open the app, it's done.
Maybe CalenGoo hasn't been updated as needed for Android 12, and if I try a slew more calendar or repeat reminder apps, I might find one that works?

Gboard Arabic keyboard layout with extra-alphabetic diacritics
I was wondering whether it would be a good idea for the implementers of gboard Arabic keyboard to include a keyboard layout, perhaps for adult and kid learners, that included the ability to insert all the diacritics, including the ones that are not normally written (the fatah (a and e sound), kesra (i sound), dumma (o u sound), shadda (doubling of consonants), sukun (small circle indicating no vowel sound), alif with small mim above (mim is for muting, I think), and tilde above alif (alif madda, I think for lengthening).
I was wondering whether it would be a good idea in Gboard to have a keyboard that allowed you to input these diacritics (extra alphabetic diacritics and all).
Can someone please point me to where I could find such a keyboard in Gboard?
The fatah, kesra, dumma, and shadda, are not usually written down, but can be used by someone for studying (/ remembering where they go).
Perhaps a special button could be added, allowing the user to add the diacritics, where it made sense.
Or, alternatively, the special versions of the appropriate characters with the appropriate diacritics, could be suggested, upon long pressing on a letter.
Furthermore, a separate keyboard, perhaps, could be selected, that would be enhanced with the availability of these special diacritics available by long pressing on the keys where they could be used.
Thanks.

Android interaction and input systems for people with severe tremors

WiFi apps not working when VPN apps are connected

Also, I have tested scrcpy and it's not working either.

That depends on the VPN and the sharing app. Some VPN allow accessing the local network while connected to the VPN, others not. Even if VPN allows local access DNS will be different which may confuse the sharing app.

Configure on-demand VPN feature comparable to the iOS on-demand VPN

We are able to configure this behaviour from our MDM provider portal.
It seems as though the Android platform itself supports this as some MDM platforms have documentation showing how to enable this feature (source). Our MDM provider, however, doesn't. Have put in a feature enhancement request. In the interim, however, is there a way we can configure this behaviour on the device itself?

How to circumnavigate an administrative filter
My android device (Samsung s20fe) has had an administrative filter called "MbSmart" installed via a USB cable to the device which restricts certain settings, like uninstalling the software and resetting the phone, and block certain apps at their discretion as well as being able to view my network activity. Is there a way to get around this without a factory reset?

If its hardware, a factory reset isnt going to work either,

The factory reset button in the device settings is restricted. I would have to do it manually. Thus leading me to believe that a factory reset would clean the device.

You don't get answers because it is too generic. What administrative filter software are you talking about? What does it restrict? Why can't you uninstall it yourself? What have you tried to uninstall or deactivate it?

Genymotion gps not working on M2 MacBook
I'm trying to use genymotion to run some automation on an app that requires location.
When I use my M2 MacBook, android 11 is the only version available. The emulator works fine. I'm able to install OpenGApps, and I'm able to install the app I need from the play store. But when using the GPS spoofing feature in genymotion, it doesn't work in any app. I tried it in google maps, and when I click "current location" it seems to hang endlessly. I've tried using 3rd party GPS spoofing apps from the play store, but those will not work either because they all seem to require my current location as well. Some of these apps give the message "google play services are updating". I tried installing Google Play Services, and updating them, but it did not help. I tried turning off and on wifi and bluetooth for location as well. No luck.
Out of curiosity I tried this again on my old intel, using android 6, 7, and 9. There, the GPS feature works perfectly, but I'm unable to install the app I need from the play store and get "this app is not available for your device", but I cannot figure out which criteria the VM is not meeting.
Has anyone experienced this before? Any idea how to fix?

Installing a custom ROM on an Android device with broken screen
I have Samsung Galaxy Note5 (SM-N920C), but the screen is deadly broken and I need to

update ROM
enabled user debugging mode
root device
and move some apps to internal storage (like GPS JoyStick/ GPS spoofing)

I already rooted and install TWRP custom recovery, but the screen is fully deadly broken.
At present, I can control that device via scrcpy-win64-v2.1.1, but last week, the game I play was updated and no longer supports Android 7.0. I need to update that device's ROM.
My question is:

Can I update the ROM via fastboot or recovery mode at ADB or another tool?
If I can pass step 1, can I bypass the unauthorized to enable user debugging mode in the new ROM via fastboot or another way?
When passing step 2, can I re-root via step 2 (rooted via adb over fastboot or recovery mode)?

I know the problem is looking so hard, but I believe I can do it, but I don't know the command or tool to do it. If someone can help or share the trick with me, I very much thank you and hope this problem helps someone not lose an old phone device and make that can come back to working via computer control. Best regard.

On Samsung devices you usually only have to enable OEM unlock in your current OS and then install the new ROM via Odin/Heimdall (Samsung devices usually don't support ROM install via fastboot). The only problem is that after installing the custom ROM I think the bootloader detects the custom ROM and may ask if you really want to continue and delete your user data (not sure about this). At this stage scrcpy will never work, so you may have to use the phone blind without screen.

How to install Artic Wolf Agent on Android?
I would like to install Artic Wolf Agent on Zebra VC8300 and MC930B mobile computers that use Android 11.
Here are the instructions I have and I'm trying to figure out which ones to follow for that build.

Run the appropriate command, based on your operating system and preferred package manager:

Ubuntu (using APT):
sudo DEBIAN_FRONTEND=noninteractive AWN_CUSTOMER_JSON=/tmp/customer.json apt install /tmp/arcticwolfagent_<version>.deb

CentOS, Red Hat, or Amazon Linux:

YUM (preferred):
sudo AWN_CUSTOMER_JSON=/tmp/customer.json yum install arcticwolfagent_<version>.rpm

Zypper:
sudo AWN_CUSTOMER_JSON=/tmp/customer.json zypper install --allow-unsigned-rpm arcticwolfagent_<version>.rpm

DNF:
sudo AWN_CUSTOMER_JSON=/tmp/customer.json dnf install arcticwolfagent_<version>.rpm

Notes:

You must place customer.json in the /tmp folder.
Use an absolute path to customer.json and verify that it is correct. If any errors occur pertaining to the customer.json file, see Arctic Wolf Agent Troubleshooting.
You can install Agent with any package manager on CentOS, Red Hat, or Amazon Linux, but only YUM has been tested.
Agent only performs automated tests with YUM, DNF, and Zypper.

Sorry but this Stackexchange is a question and answer portal but your post misses the question. Please edit your question and describe in your words what you are doing (e.g. what commands you use) and what is going wrong. BTW. Your post contains instructions for installing Wolf Agent on Linux, but Android is not a regular Linux system. So this can only fail.

I need to get deleted text messages from my android phone this is majorly important please help
I received threats in text messages SMS on my android phone and they have been deleted accidentally 4 weeks ago

Has the phone been in use for those 4 weeks? Did you receive other text messages in that time? If yes then the chance is next to 100% that those deleted messages have been overwritten. Even if you had shut down the phone directly after deleting the messages recovery would have been extremely problematic or even impossible. Asking you mobile network operator may be the better alternative. May be they have saved the transmitted messages.

Modern Android phones and Project Treble/GSI
I am looking to upgrade my phone and want to run Lineageos or similar, but in the last 2.5 years it seems support for new devices has dried up.
I see that there is are "GSI" version of ROMS of interest which seem to rely on project treble - assuming my understanding is correct.
My quretion is this - Do all Android phones which come with Oreo or newer - and realistically Android 12/13 and a bootloader that can be unlocked support Project Treble/GSI ROMs?
If not, is there ant list that can show what devices are supported?  (I'm likely looking at a Samsung S24 but could not find anything about Project Treble/S24 on it (but it looks like it does have an easily unlockable bootloader)

How to connect microSD card or external USB hard drive to Redmi 10C
I've only ever had Redmi smartphones. First a 4A, then a 6, now a 10C. The first two both used microUSB and the new one uses USB-C. The 4A was a Chinese version and the later two are both international versions.
On one or both of the old ones I was able to connect an external hard drive and microSD card using a USB-OTG (on-the-go) adapter along with either a USB hard drive cable or USB to microSD adapter. I thought I had connected one or the other to my new phone but now I'm not certain.
Currently I can't figure out any way to get my Redmi 10C to recognize any external storage I connect. I've tried with the cable that came with my Seagate hard drive, and with two different microSD cards and two different microSD to USB A adapters via a USB A to USB C adapter. All these cables, adapter, and drives are verified working on my laptop.
My phone is in developer mode and USB debugging is enabled. I downloaded an app that claims to check if an Android phone is OTG-compatible and it says the phone is compatible.
I believe that USB-C includes OTG so that unlike with microUSB, no special OTG adapter is needed any more.
I have updated the MIUI and Android versions on the Redmi 10C at least once and I think twice since I bought it a bit over a year ago. I've looked through all the settings
Am I missing something? Do I still need a special OTG cable even with USB-C? Does the Redmi 10C not support OTG even though the app says it does? Could one of the OS updates have affected it? Could it be a difference between the international version of MIUI vs the Chinese version?
Does someone have a definitive answer? Are there some steps I can follow to narrow it down to fewer possibilities?

Having problem building Android 13 for Pixel 6a
I'm trying to build Android 13 and flash it to my device, Pixel 6a.
I followed the documentation, https://source.android.com/docs/setup/start and https://source.android.com/docs/setup/build/building.

mkdir aosp
cd aosp
git config --global user.name Your Name
git config --global user.email you@example.com
repo init -u https://android.googlesource.com/platform/manifest -b android-13.0.0_r50
repo sync
source build/envsetup.sh
lunch aosp_bluejay-userdebug
m
cd ~/aosp/out/target/product/bluejay (contains all imgs like boot.img, system.img)
adb reboot bootloader
fastboot flashall -w

When it finishes, it remains at fastboot screen, so I click start. I goes to Google logo, then reboots to bootloader.
My fastboot version is 33.0.1.
Does anyone know why it's rebooting to after Google logo? Is there a log that I can look at like dmesg or logcat?
Thanks

Can't recover Storage Taken By Linux Deploy
I used the Linux Deploy app to install Linux on my phone using root Access. It seems to make a partition on my device to install Linux which took up some storage on my Phone.  Now I want to recover that storage but I find no option in the app.  Uninstalling it also does not help.

Sorry but it is not clear which app you were using. When talking about third party apps always include a link to the app, best to Google Play Store. In general your device seems to be rooted, so you can delete the Linux partitions and resize the user data partition using the common Linux tools.

Is there a way to install guest additions for Lineage OS VirtualBox
I want my lineage os virtualbox be able to resize the screen and also to use my mouse where ever I want (host os or guest os) without being stucked into one so that I will be able to copy & paste and drag & drop from host to guest and vice versa.
I was able to get those functionalities on other operating systems by installing guest additions. So I wonder is there a way for android also to do the same.
It would be a great help.

I am not sure if dynamic resolution changes are supported by Android at all, as this can not happen on Android devices. Automatic capturing/releasing the mouse is AFAIR implemented by a kernel module of the virtualbox guest tools. If the used kernel supports modules you would need the mouse kernel module compiled for the used kernel (x86?). Clipboard: I think the Android clipboard works a bit different than a clipboard on Linux, so I don't think VB guest tools would work here. Same for drag & drop.

How to add a monitor as an external/secondary monitor of an Android device
I have an app on my Android device that does a remote desktop connection to a computer, so I am able to see the computer's screen on my phone. The problem is the remote screen resolution is automatically set to my phone's resolution, so I am seeing very little of that screen. What I hope to get is to cast this remote desktop app to a normal-sized computer screen and see the remote desktop with the resolution of this monitor. I want the monitor to act as a second monitor acts when it is added to a normal computer, ie. the OS detects the new device and its resolution and applies it to the image displayed on it.
I tried using an HDMI cable to connect the phone to a monitor, but the image on the phone is just stretched on the monitor without applying the resolution of the new monitor.
Any ideas on how I could achieve this?

Samsung devices have the DeX mode which allows to use an externally connected monitor and show a UI similar to a common desktop OS. Android itself also seem to contain some sort of desktop feature but to my knowledge this feature is hidden as it not yet an official feature: https://devsjournal.com/android-12-desktop-mode.html

How can I change the fallback font on Android in Japanese?
I have a Sony Xperia 10 V that was sold in Japan, and is set to use Japanese as the primary UI language. In a few places, text in the Latin alphabet looks awful. Here's an example from the Amazon app, where the input at the top is fine but the results are bad:

This also happens in the Wikipedia app, but not in English articles - only to English text in Japanese articles. I believe it happens in other places as well, but I don't remember them all.
I believe that either this is because the default Japanese font has awful Latin alphabet glyphs that are being used, or a bad fallback is configured for those glyphs. How can I diagnose what is happening and fix it?

Is there a way to conditionally connect to specific Bluetooth devices?
My devices involved are a Sena (Bluetooth receiver / speakers for helmet), the built in Moto Guzzi MIA (Bluetooth media module), and a Pixel 7 with Android Version 13.
To play music / handle phone calls from my phone, over the Sena speakers, and allow it to be controlled by the handlebar controls, both the phone and Sena connect to the motorcycle, but not each other.
This works fine, until I turn off the engine to refuel, or walk into a store for a couple minutes. During this time I would like the phone to automatically connect to the Sena to continue playing music / minimally interrupt a phone call, and once the motorcycle is on again, switch back.
Is there a way to handle this automatically, such that the phone only connects to the Sena if the motorcycle is not available, and once the motorcycle becomes available, will disconnect from the Sena before connecting to the motorcycle?

I don't have your kind of set up to verify but using MacroDroid try creating a macro //In the first action configure Moto Guzzi and in second one Sena//Save the macro and experiment with confidence levels//If it works fine post it as an answer yourself (it's encouraged)

How to find the culprit of "no internet connection"?
I have a Samsung Galaxy S22 phone with Android 13. About once or twice a month I'm facing with "no internet connection" issue while using mobile data (not a Wi-Fi). Switching off and on mobile data transfer doesn't help, but turning on Airplane mode and switching it off helps.
The question: how I can be sure is it a phone, or a carrier problem. Is it possible to find the culprit without using a SIM card from another operator?

Turning Wi-Fi OFF and ON (or Airplane Mode) must work as network_ID is destroyed and a new one is created // To my understanding, if this works it's got nothing to do with your carrier. But I am no expert. You can maybe add that portion to your question to get better results

Adoptable storage missing on "Samsung Galaxy Tab A" after partitioning the SD card
I have a Samsung Galaxy Tab A (8"-2019). I tried to partition my 128 GB, Kingston, MicroSD card into 75% internal (adopted) and 25% external.

The partition command, for ID = 179,64; was as follows:
sm partition disk:179,64 mixed 25

After reboot, I realized that the adopted/internal part (should be, approximately, 96 GB) part is missing, and that the external one is shown.

The whole process is shown through the Windows PowerShell below:
K:\> adb devices
List of devices attached
R9WN91B9GYJ     device
K:\> adb shell
gto:/ $ sm list-disks
disk:179,64
gto:/ $ sm partition disk:179,64 mixed 25
gto:/ $ reboot
K:\>

Afterwards, I executed the following command:
adb shell sm list-volumes all

and here is the output (I cannot implement it):
K:\> adb devices
List of devices attached
R9WN91B9GYJ     device
K:\> adb shell
gto:/ $ sm list-disks disk: 179,64
gto:/ $ sm list-volumes all

       sm set-isolated-storage [on|off|default]

       sm start-checkpoint <num-retries>

Where is the adopted/internal storage?
Is there something wrong?
Is there a way to fix it?
Is there a way to undo partitioning using ADB commands?

Is my company monitoring traffic in my personal profile through mdm policies/VPN on my work profile?
My company is very high on security.
It's difficult to work with the company laptop remotely because once it goes to sleep(after about 2 mins of being idle) it disconnects from the internet and you need to log back in, connect to the wifi, connect to a VPN with your credentials, authorize the VPN via your phone and then click accept before you get internet access on the computer again.
In other to reply emails and slack messages faster, I had to add a work profile, I installed the required apps, accepted polices etc.
communications apps that connect to the company domains or work apps have to be funneled via a VPN (required installation by the company).
So basically these apps don't work without the vpn.
My main concern is that this VPN might be monitoring traffic in my personal profile although I have premium proton VPN installed, I don't feel entirely safe about it.
I've checked online and the answers I've seen are generic.
Any help here?

Sorry but your question is too confusing to being answered. 1. why do you talk about "company laptop" - this site is about Android only. 2. you forgot to tell us details about your Android device: what MDM is installed? 3. you can check yon your own if traffic interception is done, simply look at the certificate list of a site like stackoverflow.com and compare it to a device that is not from your company.

Backup.ab - Java NumberFormatException Error

Hi Kaan, it is much easier to read if you post teh text of teh error instead of a screenshot.

How large is the MyFile.ab file` If it is less than 1Kb then it is most likely invalid.

The file name suffix .ab is no guarantee of this type of backup file format. Please show the hexadecimal header of the file.

Invalid format. Compression header not found: https://github.com/nelenkov/android-backup-extractor/blob/master-20221109063121-8fdfc5e/src/org/nick/abe/AndroidBackup.java#L79

@RohitGupta i tried but i couldnt do it sorry

@Robert it is like 7Kb

@alecxs it is ab file i got it from phone with adb but before i tried to make it tar, i open it with text document so it became a txt file and i converted it to the ab file again maybe file corrupted in here

@IrfanLatif i didnt understand what should i do

@Robert By the way i got this file from folders that i can not reach without root. Maybe it corrupted because i turned it txt and make it ab again. Because of that i'm trying to get ab file again but i just got 1kb file how can i fix that

On devices running Android 12+ adb backup is limited to old apps. Recently apps that are compiled to be executed on Android 12+ don't return any data when executing adb backup. The only workaround is downgrading the app to an old version.

Well my goal was the get files from my note app folder. I found information that deleted  notes are stored in /data/data/com.miui.notes in my Xiaomi phone. I mistakenly deleted my notes few months ago so i'm trying to reach my deleted notes from that folder . So you think if i downgrad notes application (which is a system app) i can reach that files with adb backup?

First the app has to support backup at all, second downgrading only makes sense if you can go back to a version that was designed for an Android version prior to 12 (which is unlikely for a system app). Third, if you want to perform data recovery you have to do it immediately not several months later.

Loose location accuracy problem
It is very annoying to calibrate my Samsung Galaxy A53 compass every  3 minutes when I navigate in big city. In many places accuracy becomes low after several minutes of navigation. I have feeling that when phone is connected to car navigation is better.
How to solve loose accuracy problem in general?
Does using more expensive Android phone can solve the problem?
Should I move to Apple?
Can I somehow connect external GPS module with compass like I suppose is done in car?

We had recently the question how to disable magnetic compass for navigation and use only GNSS. For vehicles that move compass is not needed, only if you stop or move slowly like walking compass is often better (if it works correctly). If a compass doesn't work reliable I would assume that the phone was just designed in a bad way. IMHO it says more about the manufacturer that the platform. I headed that a lot of modern phones don't have a compass at all, may be because this loose calibration too easy?

BLU G71+ G0570WW stuck in bootloop and won't boot into recovery nor download mode
I just got BLU G71+ (G0570WW) and from the beginning, I've had problems. It was getting super hot and would just shut off out of the blue. My cousin (who is usually good with phones and computers, etc.) said if I root it, that would fix it. I don't know how, so I gave it to him, and now it's worse than it was before.
He said he unlocked the bootloader, got a ROM for my phone (something about magic?), put it in fastboot, and ran
fastboot flash boot_a boot.img
fastboot flash boot_b boot.img
fastboot reboot

at which point apparently my phone started flashing on and off, on and off, and it continues to do so. Anytime I turn it on, I have to disconnect the battery.
Please tell me this can be fixed because apparently from what I have read, he voided my warranty when he unlocked the bootloader. And it doesn't respond to power + vol up nor power + vol down. Please help. He said it's a Unisoc T610, whatever that means.

Sidenote: is it normal that in my phone settings, my phone is G0570WW, but on the little sticker with the IMEI codes, it's G0571WW?

scrcpy freezes after few seconds when connecting a samsung S23 Ultra
I'm trying to use scrcpy on Ubuntu 22.04 with a Samsung S22 Ultra connected wirelessly via ADB. However, when I run the command from the PC's terminal, the program starts, and everything works correctly for a few seconds. Then, the transmission pauses without any error message in the terminal where the process is running; the video simply freezes (if I interact with the smartphone's screen, it works correctly, but the screen changes stop being displayed on the PC).
After this error occurs, when I run a command like 'adb devices,' the device is now listed as 'offline.' The only way to reconnect to the device via ADB is to restart the PC and the device.
This issue only happens when using this particular device. When I use any other phone (e.g., Nokia 2.3 with Android 11), the connection works correctly both wirelessly and with a USB cable.
Furthermore, this error only occurs when the ADB connection is wireless. If I make an ADB connection via USB, scrcpy works correctly on the same PC.
On Windows, the program works well both wirelessly and with a USB connection.
My PC, where I encounter this problem, is running Ubuntu 22.04. The device in question is a Samsung S23 Ultra SM-S918B with android 13.
The scrcpy version is as follows:

App's notification options no longer enabling
The app in question is "Final Fantasy Brave Exvius". I've checked with their subreddit, and only one person noted they have a similar issue.
Using Samsung S20 FE and this was not a problem from near its release date, until about a month ago.
I noticed that the app is no longer giving notifications.
If I go into the app itself, it's missing the notification option all together.
If I go into the general notification settings, the app only appears when toggling on 'System Apps', and when I attempt to toggle it on there, it toggles itself right back off.
A reinstall of the app did not change this behavior.

I was wondering whether it is possible to install an app that brings an alarm into the foreground while the television is playing on Android TVs.
I ask, because, this morning, the television, and other media, were on, and I got distracted.
If an alarm had been brought into the foreground to remind me of what I had to do I would have been able to complete my task, and complete it on time.
Can you please answer me, and tell me if there is a way to install such an app, and make it work (including, installing an auxiliary alarm device (as can be done with Chromecast), to work, as an alarm, on top of the television.
By including the alarm in the television (hopefully, I can just install an app), I am ensuring the alarm goes off, and it cannot be moved away, from, the television screen (which is where is is needed).
Also, important, that a separate volume be present, to be set and override, the current settings.
But it is important that the alarm is displayed and stays there, because, in this way, you are also, reminded, visually.
Thank you for your answers.
Thank you for letting me know how to accomplish the task at hand.
Thank you.

Cannot connect Samsung device in fastboot
I am attempting to use fastboot on an old Samsung Galaxy A01. It is a learning exercise for unlocking. Based on this, the device should support using fastboot. I got it off a Samsung forum. I am running on a Windows 11 machine.
I can run
$ .\adb.exe -d devices
List of devices attached
R9HN*******     device

Which allows me to run .\adb.exe reboot bootloader which reboots the device into fastboot. The issue I cannot seem to solve is getting the drivers to work at this point.
I run .\fastboot.exe devices and nothing shows up. I checked my device management and I can see it under Ports (COM & LPT) > USB Serial Device (COM9) I have added the Samsung drivers from here and it will change to those. Each time though, I get a warning triangle on the device and it says.

This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.

I have also manually attempted to use the Android drivers here but it says they are not the correct arch?
Any suggestion on how to get fastboot drivers for this device to work?

Note that there are a lot of generated pages out there that are just "click traps" without actually containing valid information about Android rooting. The Samsung devices I had contact did not had to be unlocked via fastboot, usually Samsung devices don't have  a real fastboot mode at all. You enable OEM unlock and then flash what you want to flash using Odin/Heimdall. On next reboot the phone then asks if it should be unlocked. The COM9 you get is a good indicator as Windows never detects a fastboot device as a COM device. So you are most likely in DFU mode because there is no fastboot.

@Robert just to confirm I can do .\adb.exe reboot bootloader which reboots the device to a screen that says fastboot. Does that not matter and I should look into Odin/Heimdall? I saw those before as well but those looked more like that "click traps".

I would recommend to search xda-dev forum for your device and root. You will get some topics and the few I have checked they always use Odin/Heimdall.

Welcome to the Q&A site Android Enthusiasts Stack Exchange. As mentioned by Robert, Samsung devices don't have Fastboot mode (it's a stub/not working). Instead, they have Download mode, which can only be operated with Odin/Heimdall.

Android Wi-Fi connection DNS failures
My relative's tablet has started having problems on our Wi-Fi network. It will downright refuse to do DNS resolution (not just locally).
Some information about our network:

Wi-Fi is delivered through a bunch of Netgear Orbi APs that are connected to an Edge-X router, which is connected to the ISP's modem/router.
We are not running anything exotic like PiHole or local DNS servers.
I've used Fing on Android to perform tests, mostly ping. Ping works when using IPs but fails when using hostnames.

Some things I've noticed:

Traffic to IPs still works.
Pinging the DNS servers works.
This happens regardless of the DNS server that has been set up on the router (usually 1.1.1.1 or 8.8.8.8).
Sometimes it is solved by switching from DHCP to Static and specifying a fixed IP + DNS server IP. It might work for a couple of hours, until it starts failing again. Switching back to DHCP sometimes helps, but not always.
Playing with the Private DNS feature might also help, but not always and never indefinitely.
The problem only happens on our own Wi-Fi network.
Her relative's tablet (exactly the same model and generation) never has this problem. In fact, none of our other devices do.
The problem happens regardless of which Orbi AP the device is connected to.

I haven't tried the following things:

Factory reset the tablet (I'd like to postpone this step as long as possible)
Changing the SSID on our Wi-Fi (would also prefer to postpone since it would mean reconfiguring a lot of our devices).

Any input would be greatly appreciated.

How to prevent battery saving when power cord is plugged out (TC52)
Trying to run a CPU intensive application on TC52 without power cord connected has this unwanted behavior of turning down the frequency of the CPU(s) after just a few seconds of activity. With charging cable connected, the CPU stays in the fast operation mode.
Is there any mechanism to try to convince the OS (Android 11) that no battery optimisation should happen in this case? (One would assume, that on low battery charging level, like < 20% one would like to enable this feature, but no on fully charged device). The Battery Management settings seem to have no effect.

Windows Explorer does not show files in Android filesystem
I am using a tablet with Android version 8.1.0
I save files into internal memory using my app which get saved at /storage/emulated/0/FOLDER/filename.txt
Doing adb shell ls -la sdcard/FOLDER in windows cmd shows correct contents of this folder as well
However, when opening this location in Windows Explorer (shows up as This PC\DTABC2\Internal shared storage\FOLDER on windows 10), the files I created are not there. It shows some files and directories that actually exist (also shown in adb shell), but it also shows previous files I had created and deleted (using adb shell rn) few days ago (double clicking these files show an error, other files that also show up on adb shell open normally). It's not showing any of the other new files created today
Normally when this happens with my other devices I pull out the USB connector and reconnect the device to PC, and windows explorer starts showing the correct content. However with this tablet windows explorer is not showing updated content for reason, and shows the same files every time I reconnect. I have used windows explorer to copy files on and off this tablet, so it wasn't always like this before, but I have been saving files from my app and pulling and deleting using adb more recently
Why is it behaving this way, and ho do I force windows to show the latest contents in the tablet's memory?

Possible duplicate of Why my DCIM folder is empty seen in the computer but not empty in the phone. On Old Android versions (AFAIR Android 9 and older) Android expects that the app informs the OS/MediaService about newly created or modified files. Newer Android versions automatically detect those changes. To force re-detection you can reboot the phone as simple workaround.

Unenabling a repeating alarm, after alarm time, just for the current day
I am running Android on a Realme 8 5G phone. I am using the standard clock app that came with my phone. Suppose I have an alarm that goes off on my Android system. But, when it rings, and the alarm screen comes up, I click on the postpone button to dismiss it, and dismiss the alarm. Later, I decide that I do not want the alarm to ring again.
Can I go into the settings and turn it off and then back on (for example, because it is a repeating alarm and I want it to ring the day after, but I do not want it to ring again, for the current day. Would this work, or is there no way to do this? Can this be done silently (without firing the alarm up again (which I think is not possible anyway))?
Thank you for your answers.
