    interesting menu to test LCD in Galaxy SIII, specially the sensor button that checks accelerometer, proximity, barometer, altitud, light, gyroscope and magnetic sensors. Try gyroscope graph and move your phone in all directions. The touch button can help to detect defects at any part of the display. In my case everything works ok.
