When i press a button on my iphone it presses something else.What do i do to make it stop?
The touch screen is faulty. There is no need for calibration on the iPhone touch screen, and there's no provision for it. It's a projected capacitance touch screen - you can't recalibrate them. Just replace them.
your touch screen needs to be calibrated
The buttons need to get fixed. Take it to the technician.
calibration. although this is a common problem you shud probably just request a replacement
