Xperia T- Bluetooth Issues since Andriod 4.3 Upgrade.

[klf3]

Hello All.

Since my phone was upgraded to Andriod 4.3 Jelly bean, I've been unable to make calls from my phone via my BMW car audio as before, as the Bluetooth link keeps dropping out.

I've tried re- pairing the phone to my car, but this has made no difference.

The Bluetooth seems to work ok with other devices.

Questions are:

1) Does anyone know what the problem is and how to fix it.

2) If not, is it possible to re- install the previous version of Bluetooth that came with Android 4.1 Jelly Bean and worked perfectly ok with the car audio.

3) As a last resort, is it possible to install a 3rd party Bluetooth App to try and resolve the problem.

Hope somebody out there can help !

I've experienced exactly the same problem with my XPERIA SP and Opel CD400 unit since the Android 4.3 update. With the previous Android version it was OK (except the poor an quite sound quality in comparision to my previous HTC Sensation XE phone where the sound quality was superb with the same head unit)

I'm really disappointed with this 4.3 update it is even slower and have no any pros only contras. Until now I din't find any way to revert back the FW.

I Have an Xperia Z and once again since the update battery drains superquick, the phone gets hot and the bluetooth is all but useless, I work for a motor dealer, since this update I cannot pair my phone to most of our vehicles to demonstrate the system (and yes it did pair fine to these cars and vans prior to update), I get the message Bluetooth share has stopped or it will re-boot the entire phone, I did have a conversation with Sony who deemed that I should back up and restore the handset, which once done may or may not work (it didn't) and they seem to be completely denying a problem, which as I have checked various forums there very clearly is a major issue
