Might as well post up since I've been wondering.
Sometimes, completely randomly, I'll be watching a video on MX Player and the picture will freeze but the sound will keep going. The whole phone kind of locks up with the frozen pic, and the sound going. If I hit the area where home would be and the lock screen, it'll go after about 15 seconds or so, then I just unlock my phone and continue and everything is fine. I never experienced this until maybe the last 2 weeks or so. I'm assuming it is an mx player issue, but just wondering if anybody has experienced the same?
