My bluetooth has been acting weird too. It just turns off, and then I can't turn it back on again. The connection with my car keeps dropping in and out, and it isn't syncing with my Fitbit. I keep restarting my phone. That worked for a little bit. Now it only works maybe one in ten times. This is super annoying. I've tried deleting synced devices and re-adding them, and that doesn't work. I just checked my phone to make sure it doesn't need a software update, and it doesn't.
