Need help! I have my S3 for 4 months now. Last week I was watching a movie on it and for some reason the movie closed itself and opened again on the same spot. It does that a lot now. Also when I play games like Temple Run or Subway Surfers the pause menu pops up. For Bike Race, the races just restart at anytime.

Anybody have a solution? I don't want to tell my parents because they'll think it's my fault (probably is )
