No fix as of yet, I’m on 2.5.2 and facing it still. Just bought the phone recently and I’m afraid I’m gonna have to sell it sooner than I thought.
On my side the problem is much more severe since I am literally unable to make calls through my VW’s audio. The other party is able to hear me for 5-10 seconds and then it’s just dead silence. If i switch to earpiece and then back to car audio, I can speak for another 5-10 seconds. Tested in two VAG cars already (VW/Skoda), same on both of them. Factory reset did not help.
This is utterly ridiculous.
