Hi! I was assigned to a tablet should block all services in addition to the multimedia player, which is pre-installed for playing audio files can only be used. If I can find a solution that can only be avoided by installing the system again then I get a success since the tablet thus losing the essence of pre-copied two files, you can not get anywhere else but here. Android 5.0 tablet that the system can be improved 5.1. Do you think this is possible under Android or remains in any Linux distribution?
