My SIII has completely locked up. The "unlock screen-swipe" isn't working and I CAN'T EVEN TURN IT OFF to try and restart. So there it sits turned on but completely unresponsive. The only thing I can do is receive a call. When I do I get a message that says..."Touch Wiz isn't responding. Do you want to close it?.......Wait.......OK. Suggestions? P.S. At this point any suggestions to download some app will not be helpful (I don't think) since I can do absolutely nothing right now.
