After last update, the Bluetooth connection with the car doesn't work properly and despite if I send or receive a call, they hear me but I can't hear anything.
On this situation the phone in the car is useless.
Before the update, with the last ROM was working normally.
I had the same problem some weeks ago. The solution in my case was very simple:
1) Connect the phone to your car.
2) Establish a phone call (maybe to your Mailbox).
3) Use the hardware volume key on the side of your phone to increase the volume.
I hope this is the solution that works also in your case.
I've checked the Bluetooth car connection with a Samsung A5 and it works flawlessly.
I'm convinced the guilty is my UMI Super.
With a bit more time, I'm going to flash current ROM and if it fails, then the previous ROM that was working fine for the Bluetooth connection.
I am back to 20160708, and I am very happy now. I didn't have problem with Bluetooth but with sensitivity of screen /touch when phone was on table and with finger print sensor /slow screen switching on
i have the same problem - i stopped using the phone because of that...which is a shame because most other problems were fixed...bluetooth is a problem - and low voice on speaker on calls...but the bluetooth problem is very annoying...
