Hi

I have s22 ultra, 1Tb with Samsung Buds.

After the last android update, my Bluetooth persistently disconnects from my cars Bluetooth during a call making it unusable.

I tried to report on Android developer forum, but it is user hostile, confusing and un-targeted.

Where can I get help? After spending €1800 on a phone, is my only solution to change phones?

Any help appreciated,

Andrew

PS Works fine with my old phone and my wife's phone

Hi, changing phones won't help, your car is struggling with newer Android Bluetooth protocols. In developer settings under Bluetooth change your AVRCP settings to a lower version. If that doesn't work your car's Bluetooth module needs updating.

Hi, @AndrewKelly. Firstly, thanks for posting. I moved your post to the S22 Series board, so that our Community users are more likely to see it.

You may wish to have a look at the guide that was created by our colleagues from Samsung US:

https://www.samsung.com/us/support/troubleshooting/TSG01209182/

We understand that your Bluetooth is disconnecting after the latest software update on your S22 Ultra. So, if the tips in the guide above didn't help, I'd recommend consulting and following the tips in the guide below:

https://www.samsung.com/uk/support/mobile-devices/how-to-troubleshoot-software-update-issues/

In the unlikely event that this doesn't resolve the issue, I'd definitely recommend reporting this directly to our engineers, as they'd be able to take a closer look. Here's how you can do that:

https://www.samsung.com/uk/support/mobile-devices/how-do-i-send-an-error-report/

I appreciate I'm sending a lot of guides there, but I just want to help ensure you get this resolved as soon as possible. 

Please keep the thread updated by letting us know how you get on. 👍

Try clearing caches before uninstalling, I have commented elsewhere today explaining uninstalling does not necessarily clear the caches. I also get more variety and help by doing a general Google search as you reach more posts than just relying on Samsung members or specialist forums.

The phone worked with the car (4 years old) for 4 months before the problems started after upgrade. Also, I have no problems with S21, S8+ , S9 and iphone 12.  I will try what you suggest, that is interesting. I was really hoping I could roll back a version on the Bluetooth and try.

My phone also did an update for the buds and I have read elsewhere that developers have had problems with android 12 and Bluetooth.  I also had an issue with the galaxy buds, like they went out of synchronicity but that seems to have sorted itself.

Uninstall what, the last software update? How do I do that?

Also, how do I clear the Bluetooth cache?

My apologies. I was thinking of standard app processes. However, I did some Googling with some result. First, Google "samsung bluetooth stopped working" and go through some of the suggestions and one particular link in the results https://squareup.com/help/us/en/article/6828-clear-your-android-device-s-bluetooth-cache
Unfortunately you can't uninstall updates for the system overall. One draconian option is to do a reset to factory default but I would only do this as a last resort as you lose your data and app installations. Mind you, backup options (do more than one backup, Smartswitch and Google) mostly fix this but not completely.

I have tried all the old protocols. This is not the problem.

I have verified the car's hardware and software, so the issue is in the phone hardware or software.

This only broke after a software upgrade.

Now I have an €1600 S22Ulta (1Tera version), a few months old, and I can't use it in the car.

Samsung Technical support fixed this today, by resetting the Bluetooth settings, as follows:

1. From the home screen, either swipe up or down to access apps.
2. Select Settings.
3. Select General management.
4. Select Reset.
5. Select Reset network settings.
6. Select Reset settings.
7. Enter your screen lock PIN, Pattern or Password and select Next.
8. Select Reset.
