Touch Screen Test

There are three color-related tests (purity, gradients and shades) and two touch-related ones (single and multi-touch). The Display info button opens a page that contains data about the screen resolution, pixel density, aspect ratio and current brightness. Depending on your phone model, these tests can help you decide, for example, if the eye comfort mode must be enabled to prevent eye strain, if the brightness level requires some adjustment or find out if the touch sensitivity is still good all over the screen's surface. The color tests and Information require one tap for every page. Anyway, you can exit anytime from the current test with a double-tap somewhere on the screen. The Single-touch test is complete when the whole screen is filled with blue rectangles - including the area occupied by the upper text message. If the touch screen proved to function properly, the Multi-touch test helps you check if several fingers (maximum ten) can be used simultaneously to make multi-finger gestures in your apps. Finally, two animation tests indicate the frame rate of your display (in Frames Per Second) while a cube or a few rectangles move all over the screen.
