1. A method for determining that a fault condition exists within a touch-sensitive display of a mobile device, comprising:
prompting a user to touch a plurality of points on the display;
prompting the user to drag the plurality of touched points across a displayed pattern;
illuminating the display with a painted area where the user dragged the touched points to confirm areas touched by the user;
measuring a respective plurality of pressure values from touch zones respectively associated with the user's contact with the plurality of touched points as the plurality of touched points are dragged across the display; and
determining a display anomaly by determining that two or more measured pressure readings from a first plurality of the respective plurality of pressure values changed more than a predetermined amount.
