For a couple of months both of my games have been flickering badly, to the point where they are impossible to play. It has progressed from just the startup-loading screen to constantly during the game. Sometimes if I clear caches or shut the tablet down and restart it helps for a few hours but now nothing helps. I have even deleted and reinstalled the apps. I have an asus memo 7 tablet and have played daily for at least a year or two with no problems. I have adequate free space on the tablet.
