Samsung Mythic A897

Has anyone else had touch screen problems? I bought two of these phones for my daughter and I and both have had the same problem with the touch screen. The sensor moves too far to the right which means things on the left side cannot be used. I have reset it, rebooted, and took it into the store. The verdict: I need a new $100 screen. Now that the second phone has this problem, I think it must be a manufacture's problem and would like comment from anyone else who has experienced this.
