Car Bluetooth Audio keeps stuttering

[Kingsherry]

Hello wtf is wrong with this new latest and greatest. My note 9 doesnt lag whatsoever in my car but the s21U lags and stutters while playing music. Screen cast doesnt even work properly either!

The car may have an older Bluetooth version and the synchronisation may not be efficient.
Try to delete and reconnect with a new pair.
Also, install Galaxy labs and inside, install app booster. It will take about 10 minutes, but it will solve some of the problems, mostly if you just had new updates.
