I just started having problems with my iPhone 5's touch screen. It is not crazy erratic like in previous posts, but there are a few problems. One is that about 10% of the time, it repeats my action twice (esp. during keyboard use- makes typing aggravating, and makes entering passwords almost impossible. Words look like this often: "Pplayiing".) it also just doesn't respond sometimes. Sometimes it's slow. And its not just in the keyboard, its all over. This just started today and I've had it since launch. Is anyone else having similar problems? What do I do?
