About this test
'Ghost touch' is when the screen registers touches on its own, opening apps, typing or scrolling without you. This tool visualizes every detected touch and counts the total.
With the phone untouched, no marks should appear. If they do, you have ghost touches, usually caused by a failing digitizer, a bad screen protector, a poor-quality charger or moisture.

Frequently asked questions
What causes ghost touch?
The most common causes are low-quality screens or protectors, non-original chargers, moisture and digitizer damage after drops.
How do I fix phantom touches?
Remove the protector, test without the charger plugged and restart. If it persists, the screen/digitizer likely needs replacement.
