iPad 2 screen won't scroll to next page

On the home screen of my iPad 2 runing iOS 5, I can open apps by double clicking on them. But it won't scroll when I try to scroll the screen to the next page. It seems that the voice repeats everything. I can not also shrink or enlarge pothos, and even can't scroll down the page in the setting. How can I fix the issue?You need to turn accessibility features off by the following steps:* Connect
