Reading the test
- A button never turns green - worn switch in the mouse, or a touchpad click mechanism / cable fault.
- Gaps in your lines - dead zone on the touchpad or touch screen (cracked digitizer, liquid, or the touch cable).
- Lines jump or draw by themselves - "ghost touch": often a damaged or non-original touch screen, or a faulty charger causing interference.
- Max fingers shows how many touches the screen tracks at once (most phones 5-10).
