Start by cleaning the screen then if you have no joy test the touch screen sensitivity does the touch screen work on other apps in all areas of the screen or do you have dead areas. If this is the case the digitizer may be in need of replacement . Has the phone been dropped or exposed to a lot of heat ? Has it got wet ? if so these are all factors in deciding what went wrong
