Help Bluetooth won't transmit my voice

svim
If the your Galaxy A51 was fully functional before that roller coaster ride and you only started to have this Bluetooth - voice problem afterwards, that might indicate there's a hardware damage problem. All the things you've tried are software-based solutions, which won't necessarily be able to fix a hardware problem.
But I hope I'm wrong on this. You might want to try going through the arduous process of a Factory Reset to see if that makes a difference. (Yeah, that's another software-based solution but well, just in case.....)
If you do opt to do a Factory Reset, be sure to backup your data first. Try Samsung's Smart Switch utility to do a backup and restore.

If you just want to send your phone to be looked at a trusted service center, be sure to enable Samsung's Maintenance Mode (if your A51 model supports it):

Help Menu icon home Page problem

Try putting your phone in safe mode. Safe mode prevents any 3rd party apps from running. If it is not there is safe mode then it is associated with an app you downloaded.

I would uninatall all recent apps...... starting with the most recent app and work your way backwards.

The best way to uninstall is to first locate the app in app management. Then wipe cache and data, then you can uninstall it. Keep doing this until the icon goes away.

There could be several reasons why Call of Duty mobile is laggy on your Samsung Note 9, even though it runs smoothly on your Samsung Tablet. Here are a few things you can try to improve the performance:

  1. Clear Cache: Clearing cache data can help free up some memory on your device and might help improve performance. Go to Settings > Apps > Call of Duty Mobile > Storage > Clear Cache.
  2. Disable Battery Optimization: Sometimes battery optimization settings can interfere with game performance. Go to Settings > Device care > Battery > 3 dots menu > Settings > Sleeping apps > Remove Call of Duty Mobile from the list.
  3. Check for Updates: Ensure that the game and your device are up-to-date with the latest software updates. Check for game updates in the Google Play Store and software updates in Settings > Software update.
  4. Disable Power Saving Mode: Power Saving Mode can reduce the performance of your device, so disable it while playing the game. Go to Settings > Device care > Battery > Power mode > Turn Off.
  5. Disable Background Apps: Ensure that no other apps are running in the background while playing the game. Close all apps from the Recent Apps menu.
  6. Lower Graphics Settings: Even though you've already lowered the graphics settings to low, try lowering them even further to see if it improves the performance.
If none of these solutions work, it's possible that your device's hardware is not powerful enough to run the game smoothly.

Help Can i 'undelete' my erroneous sd card?

Hadron
Depends on what computer operating system you use. But for just recovering files from an SD card most recovery tools will do the job, so if I assume you are using Windows (as people who don't specify usually are) then try Recuva as that's free.

If you have something more serious, such as master boot record failure on the card, then you may need something more sophisticated. And there are some failures from which nothing can be recovered (especially if the card was encrypted, as will be the case if it was "formatted as internal storage" on Android).

I know nothing about phone apps for this: it's one of the many tasks I'd never use a phone for.

LG V30 calling issues during roaming.

Thanks for the information. The phone hasn't worked driving from Tennessee, all the way into the keys

So according to Wikipedia you should have roaming agreements with ATT, T-Mobile and VZW. Your phone should support some of the bands used by those networks (e.g. band 2 and the 4/66 AWS pair), but I don't know what bands are deployed in what regions (simple things like FCC coverage maps don't go into such detail) so you might just be unlucky in where you are (or it may be that something else is wrong, perhaps with the way USC set something up. Can't really know).

Duplicate lock icon besides the default on the lock screen (Samsung phone, Android 12)

I could be some app you've installed doing it, and AF has had reports of this before.

I know the DiDi car hailing app can show its own lock-screen, but only when it's actually in use with a ride booking in progress.

Rooting And. 8GO and 11

Hadron
I would always use a computer. Indeed I'm not sure there are any methods for a semi-modern phone that can be done without one. Magisk is probably the main tool for most phones these days, though I'm no longer following closely. It's complicated because this isn't a simple business, and because the instructions include options for different phones (so once you know which options apply to you it becomes simpler).

SDK Tools is how you will find Fastboot and ADB (Android Debug Bridge, used for USB debugging commands) if you use Windows - on other platforms these are available as standalone binaries (possibly for Windows too, but I don't use that. I have however seen instructions for obtaining these that tell you to install SDK tools for Windows).

Slow Internet

Hadron
Weird link: your graphic talks about backing up files, which is nothing to do with the content.

Anyway, I don't think anyone will be able to say much on the basis of what you've told us: that your internet is slow and that you are using BT. That's very little to go on. Does it affect all devices or just one? What do you mean by "quite slow" and how does it compare with whatever package you have? Have you used BT's tools to check your connection speed? This is now in the "My BT" app, and will tell you the speed to your hub as well as from the hub to the device. What sort of connection do you have (if it uses the copper wires you may suffer slowdowns when too many people are using them, fibre to the premises should be more reliable for that)? The more information you can give the more chance someone will be able to help.

Unresponsive task switcher bar

King Mustard
Since I was upgraded to "Coolwalk", the task switcher bar is unresponsive to touch input most of the time, and I can only swap between apps using the voice assistant when it occurs.

This happens in wired or wireless modes. Car and all phone software is updated.

Everything was fine before the Coolwalk update.

Has anyone else experienced this?
