bluetoothd have no argument n, added pproperty permissions for bluetoothd and probably mised permission for camera
1. logcat say: init: sys_prop: Unable to start service ctl [bluetoothd] uid:1002 gid:1002 pid:2661
2. logcat say: init: sys_prop: permission denied uid:1013 name:camera.0.name

Hope thats ok by now.
