The best way I can describe a test would be:
Download Temple Run (game that you must swipe up, down, left and right). Try beating the first level. It was impossible for me to beat because I would try to swipe up and it would go down or left instead, etc. Just really off... anyone else have this issue?
This is the only thing that is hindering my tablet from having ICS; I could care less for the camera, my phone's camera is 100x's better anyways....
