Since the recent software upgrade to 4.3, I have been experiencing a very annoying problem. I regularly use my Samsung S3 with the headset with no problems, but since the upgrade every time I receive an incoming call, I hear it ring once in the headset then the headset becomes inoperative (no sound or controls), the phone itself continues the ringing. After answering calls, using the handset instead of the headset, all further attempts to use the headset are futile. The only way to re-establish the headset functions is to power off and then power on, only for the problem to arise next time the phone rings. I completed a system (software) reset and changed the headset, in the hope that this would resolve the problem, but it still persists. Any ideas?
