Me and my farther both now have iPads, he got his first and realised after using things like Google Maps or watching a video on youtube around 5 minutes long, The bottom half starts fuzzing and all the bottom icons start having double visions.. This clears if you lock it and un lock it but it seems to be when a high consentration of CPU (shall we call it) is been used.
Could this be a loose cable or some sort of overload with heat problems?
It doesnt feel likes its over heating..
