My iPhone is getting stuck for a few seconds everytime I do something, if i type a letter it will type it twice or a few times, if i click to close the browser it stucks there for a few seconds before closing, if i try to open some app it gets stuck there. I have restored it and loaded the backed up material again. But this problem doesnt seem to go away. Sometimes it is too much sometimes it is not noticeable, so what exactly could be wrong and what ALL should I do to get it fixed? Please reply.
