HTC won't acknowledge anything. They think it's user error. We have 3 cars that I've tried to pair BT to. It does not work. It worked fine on Android 4.2.
The new Google map took away all the good features off and now I'm dealing with Bluetooth that connects and reconnects like a possessed phone.
I'd sell my children to get 4.2 back.
HTC One with 4.3. Disconnects and reconnect every 10-15 seconds! It renders BT useless. Crap like this and the new Google maps just shoots HTC in foot everytime. Beyond PISSED. Can use the phone in the car at all!
Exact same problem with my HTC and 4.3. Bluetooth connects then drops every 10-15 seconds. This is ridiculous. I thought the new retarded Google maps was bad, but not having functional BT is wrong. Never had a problem before 4.3.
