I'm having similar problem on my Audi TT. I complained to Audi and thought that it was their issue until I found that there are numerous users with same problems.
Baseband version N960FXXU2ARI4
Audi TT 2017
Would appreciate this be fixed soonest. Non of the apps that is required audio works including Googlemap, spotify, etc.
Samsung Galaxy Note 9
BMW 328i 2013
So disgusted. Tried the cache clear twice. The phone is useless to me if I can't use it in my car.
Handsfree state but even so last 4 Moto phones connected and synced with contacts, etc. with no issues.
Connects, no contacts and no way to make a call hands free. But matters not as when I manually instigate a call it goes off on Bluetooth within a few seconds.
Model code of Phone: SM-N960U
Hardware version: Rev 1.1
Model of Radio: Stock
Make/Model of Car: Fiat 500
Won't allow media audio... only contacts and phone. Immediately shuts off when go to toggle it. Had a iPhone that never had problems and I just got the note 9 and it worked fine for 5 days or so and now it will not work
Baseband version: N960FXXU2CRLT
Carrier: PrimeTel (Cyprus)
Car: Range Rover Evoque 2018

Same issues as everyone with my note 9 One UI.
This 100% fixed mine. Got the new note 9 - My phone had paired once and worked great - next day I could dial but nobody could hear me and I couldn't hear them. ...used the fix below and instant and so far (several weeks later) permanent resolution.
Delete from your car, unpair from your phone, as above turn on dual audio in (connections, Bluetooth, three dots, advanced, dual audio to on) and then reconnect Note 9 to your car.
