Hi. New to the forum and I did try searching first, but didn't see my issue raised. I bought the iPhone 4S when it came out. It was working fine until this weekend. At first, I couldn't type in my password. I ultimately figured out that I had to tap the number I wanted to enter once, at which point a box would appear around the number (as if it was now highlighted), and then I had to double tap the number for it to be entered. Once I got to the home screen, I have to repeat the same sequence. For example, to get on Safari, I have to tap it once, to get the box over it, and then double tap it to launch it. Wheher in Safari or mail or anywhere else, I cannot scroll up or down a page nor can I enlarge or shrink a page. For example, if it try to enlarge a page, it just places a rectangle box around some of the text on the screen. The functions on the phone still work. I still receive calls and emails for example, but its impractical to use as I can't even scroll down to read an email I received. My kids were playing Angry Birds on it before it stopped responding. They said it was working okay and they just decided to stop playing. I tried the trouble shooting suggestions by apple (except for restore) but nothing has worked. Thanks in advance for any suggestions.
