The Touch application helps with checking and setting the touch layer, which is necessary for controlling the controller. The entire display is divided into 144 identical squares (12 x 12), which need to be checked by touch. Just move your finger across the display and green squares will gradually appear, showing that the touch is working in the given place. If all the squares are filled, the touch layer works correctly in all places and the screen returns to the app selection.

If it is not possible to color some places on the display green (mostly the edges), it is necessary not to touch the display for 10 seconds, the Touch application will end and the application selection screen will be displayed. Now it is advisable to calibrate the display carefully (Article Touchpad calibration) and then perform the touch layer test again.
