Useful to resolve "Can't connect to Camera" errors (occuring e.g. on the S3 with CM13) without a device reboot.
-Added alternative flow beginning (could be manually installed as a homescreen shortcut when the QS tile doesn't work)
- Added Quick Settings tile for faster access
- when unable to create QS tile, a log message will be shown and the Media Server Killer will be executed immediately
