I posted a message about problems with my bluetooth car system about one week ago. I didnt get any response. Since then, I decided to get a new bluetooth headset and the exact same problem occurred. It has to be the phone, obviously! I am able to pair, to connect , to place a call and to starr talking via bluetooth. Then, without any warning, I stop receiving the sound in the bluetooth device, but the call is still going on and the person to whom Im talking keeps hearing me well. This happens all the time, sometimes after few seconds , never longer than 2 minutes into the conversation. needless to say, short of a factory reset of the phone, I did everything I knew I could do, reset bluetooth many times, turned off and on the phone, reset the headset, all to no avail.
