There are different numbers of color-related tests (purity and shades) and two touch-related ones (single and multi-touch).
The Display information function to display data about the screen resolution, pixel density, aspect ratio and
current brightness. Depending on your mobile phone model, these tests will help you decide, 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 surface. The pixel color tests and Info require one tap for every page. The Single-touch test is complete
