Unlock button lock if BT is connected: In the previous version the button lock coluld only be disabled by following the correct button press order. In case a button does not work (e.g. low button sensitifity) the OSTC would be locked. To avoid such a scenario the button lock is now also removed if the OSTC is connected via Bluetooth
