I'm om 4.3 now, still the same. Almost all games are unplayable... I'm starting to think it's a hardware problem. Could the disabling of a service be causing this, cus I disable a lot of them.
edit: I found that pressing the screen a little bit too hard makes it unresponsive. Definitely hardware problem since I've changed screen glasses before. I'm losing hope for fixing this :/. Any suggestions?
