--apps open, seems like someone else is controlling it! I disconnected it from my WiFi in my house with same problem. I powered down and then back on (a few times), but same problem. When I was powering it down, it seemed like someone else hit the CANCEL option before I could select the OK button, and I had to do it again and quickly select OK to get it powered off. Has it been hacked? Please HELP!
If you continue to have issues in Safe Mode, you'll need to Factory Reset after backing up the phone in Back Up and Restore in the main settings menu. (Make sure to disable app and app data backup AND restore...uncheck all the boxes)
