Hi, When my phone disconnect from my car bluetooth, wifi goes off, sound to mute and bluetooth to off...... anyone ever experience this? But not every time, like 2 time out of 3. doent seem to do it when disconnecting my pebble..... and didnt do it when I just went to car and connect and disconnected from the car audio. But did it just as it connected the first time to car......

google didnt not help me much so far. gonna try to refine my search but any hint would be appreciated
