I have this problem since day one. Build .29, then came the FW update, then build .63, always the same. I did a hard reset three times since I have the phone but the problem is still here. And now to the actual problem: I have a plantronics voyager legend headset and sometimes during a call, sometimes when not in a call, the phone disconnects from the headset and it seems to be frozen, I can't even unlock the screen for 5-10 seconds. Bluetooth option becomes gray and sometimes BT turns on again after 10-15s, sometimes I have to reboot the phone because BT can't be turned on. Same thing happens when the phone is connected to my car, but when it's playing music on bluetooth speaker, everything is working ok.
Does anybody have any ideas? As a last solution that I can think of, I am going to try and reinstall the SW with lumia recovery tool.
