I have a Galaxy SIII mini which has been hacked 4 times in the last 8 months that I have had it. Usually, the first 3 times, were kids doing pranks, turning on my bluetooth,etc but this last hack was malicious. Started turning on my GPS, bluetooth, and camera flash light then progressed to changing my system language and finally making it so that my sim couldn't connect to any cell towers. I have tried app locks, but this last time inspite of two seperate app locks, he succeed with ease to change my settings. I also subscribed to a VPN with a NAT firewall and that didn't help at all either. Now I have redid the OS again, this time installing CM 11 and I welcome any suggestions on how I can stop this from happening all of the time. The hacking is always done remotely. No one has physical access to my phone. Thank you.
