Can you give us some more informations to reproduce your problem?
- Which android device and android version did you use?
- Did it work in our previous stable(3.1.6.1)?
- It would be nice to know the steps you did (Did you connect the phone to the car-bluetooth before or right after you started the TS3 App etc...)
- Can you try to disable and re-enable the "Use Bluetooth" setting, while you are connected to a server and tell me what happens then?
- Do you own a normal separate Bluetooth Headset you could use to test?
