Hi guys, i just replaced my iphone 3gs yesterday and noticed that my iphone's sensitivity is really high. when i try texting and for instance type "the" the phone thinks im holding down on the screen and moving from T to H and then E so it only types in E. my older 3gs that i replaced didnt seem to have this problem when i typed fast. do you think replacing the screen will fix the problem? if so, do i just make an appointment at the genius bar and get it replaced?
