While watching a movie on my galaxy s3, after about 5 minutes my phone will freeze audio still plays but my touch screen and phone remain unresponsive after that it restarts. I'm using my external SD card to store my movies, it's a SanDisk mobile ultra 64gb XC class 10. The movie is mpeg4 and about 1.2gb ,I have no idea why its freezing I have tried deleting and reinstalling the movie and clearing media data both did not work. Any info on how to fix this issue is greatly appreciated.
