Touchscreen Test
Use the drawing canvas to check touch accuracy, multi-touch point count and ghost touches. Trace slow lines across the screen edges and diagonals; breaks or jumps can indicate a hardware issue or a screen protector causing interference. The tool also shows active touch points so you can verify your device’s maximum simultaneous touches.
- Remove smudges, clean/dry the screen.
- Tap Start Test and draw slow lines across the grid.
- Place multiple fingers to confirm multi-touch support.
- If you see stray dots, remove the case/protector and retest.
Touchscreen — FAQ
How many touch points should I see?
Most phones report up to 10 touches; some devices support fewer.
Why do I get ghost touches?
Moisture, poor protectors, faulty digitisers or noisy chargers. Clean/dry the screen and remove accessories; if it persists, consider hardware service.
Does this test store my drawings or data?
No. Everything runs locally in your browser — nothing is uploaded or saved.
Will it work with a stylus or pencil?
Yes, if your device exposes the stylus as a pointer/touch. Pressure and tilt aren’t measured.
