Can someone please help me?!? My son's IPad 4 had the screen replaced due to a crack. He got it home and plugged it in and was playing Minecraft and then it started glitching. He turned it off and when it came back up it asked for his passcode. When he types in the passcode the middle line does not type, it defaults to the first line. I thought maybe if I disabled the passcode and just get in I can figure out whats going on. Has anyone experienced this glitch?
