Default screen issue

Anyone notice, or experienced any issue in regards to the screen being unresponsive? Like the unlock screen when fully charged, and connected to the charger? Also during game play some times the screen wont respond accordingly to a joystick, or continue controlling a particular button while not being pressed. Even in game content isnt visible. Example: I play order and chaos online. For those unfamiliar its an mmo game (supersweet) generally on any other device, I could multiple mobs pf 10-20 with no issues. On this device however, I get maybe 3-4 mobs and they start to disappear and I am no longer able to see them. They still are attacking me, but I cant see them. Any suggestions? Screen issue? Should I try a rom? Im using samsung tab 3 10.1 wifi stock and rooted 4.3



Too big for you? Don't worry, I'll be gentle...
