I have a 2017 NX200T F Sport.

Previously I had a Note 8 and it ran great in the car. However, just recently upgraded to a Note10+ running Android 10 and have had connectivity issues. It started about a week after I had the phone. The first week it was working great. After about a week it would connect for 45 seconds, disconnect and reconnect again but only for 45 seconds.

I find that when I clear the Bluetooth's Cache and Data, it works for about a day or two. Then it goes back to the same connection issues.
I have tried turning off the battery optimization for a multitude of apps I frequently use. This helped it for maybe a few days and it has gone back to the same. I feel it is indeed a bluetooth connectivity issue. My next plan of action is going into the developer mode of phone and forcing it to use each codec only.

Does anybody know what codec the NX's bluetooth is?

Update March 16. I tried manually forcing it under different codecs using the developer option but that didn't fix. The problem is really intermittent now and not as frequent in terms of disconnecting issues. At this point, I think I will just live with it even though it is frustrating when the problem comes back especially while I am in the middle of a call. I will await for any Android 10 updates in hopes this gets fixed on a firmware issue.
