Frequently Asked Questions
How do I test my phone touch screen online?
Open the touch screen test, press Start Test, then drag your finger across the entire panel. Any unpainted gaps can indicate dead zones or poor edge response.
Can this test detect ghost touches?
Yes. Start the test and leave the screen untouched for 30 to 60 seconds. If marks appear without touching the screen, your device may be registering ghost touches.
