I also did the latest ios update. The same night I thought I was loosing my f-----g mind when my screen started zooming and changing colors when I flipped it over or shook it a bit. Finally I called version and they replaced the phone. I honestly think someone hacked the program with a fake certificate, then rewrote the code to the program and made it act malicious. A lot was changed after, phone number, location, emails, ect. .... Just call your telephone company and ask for replacement. Good luck ;)
