Touchscreen Test

Swipe the whole screen until every square turns green. Squares that stay dark are spots that don't respond, often called dead zones.

Swipe the whole screen

  1. Press Start test. The screen fills with squares.
  2. Swipe every square until it's green, corners and edges included.
  3. Put several fingers down at once to check multi-touch, then press Finish.

Results show here once you've finished swiping.

Other tests

How it works

  1. 1Press Start test. The screen fills with small, fingertip-sized squares.
  2. 2Swipe slowly over the whole screen, corners and edges included. Squares you touch turn green.
  3. 3If a square stays dark after swiping it several times, that spot doesn't respond to touch.
  4. 4Put several fingers down at once to check multi-touch. The most fingers read at once is shown in the result.

Common questions

How many fingers is normal for multi-touch?

Modern phones usually read at least 5 to 10 fingers at once. If only 1 or 2 register, the browser or a screen protector may be the limit rather than a broken screen.

What about ghost touches (the screen touching itself)?

Watch for squares that turn green without being touched. That's a sign of ghost touches, often caused by a lifting screen protector, a non-original charger or a damaged panel.

The corners are hard to turn green?

On curved screens or with a thick case, corners are harder to reach. Take the case off and swipe slowly from the edge towards the middle.
