the touch screen doesn't seem to be responding well or is incorrectly callibrated, but only sometimes..

Example: writing a text message does SIP doesn't pop up automatically, so i tap the screen and it appears as if the cursor went down? like the area i tapped on was a down arrow or something, i have to tap random places on the screen for the SIP to pop up (usually a few centimeters over from bottom right of the actual SIP icon at the bottom)
