Every so often when I start a fight, the screen immediately goes blank. I can still hear the sounds and inputs work but nothing on the screen. Other apps on the phone are fine, just mcoc. I can end task on the game and go back in where it restarts my fight over but it's annoying that this happens. You can hear your champion getting combo'd into oblivion while you freak out. This is the only game on my phone and a fresh install maybe 2 weeks ago.
