On a touch screen, rub the whole grid area with your finger. Check whether any cell does not respond, and in the multi-finger step see how many touches are recognised at the same time. Use it on a device with a touch screen.
Everything is measured inside this page. The measured values and results are not sent, saved or recorded.
Measure
No touch screen was found on this device. This test measures only touch screen and pen input; the mouse is not used. Please open it on a device with a touch screen.

Internal criterion: if, after the user confirms that every cell was rubbed, any cell was never touched, the result is Check needed. Events may not arrive at the screen edges (system gesture areas), so the web page gives advice about that.
How to use and FAQ
?How do I use the touch test?
Press Start and rub the grid area with your finger all the way into the corners. When you are done, press I rubbed every cell; if any cells are hatched, rub them again. After the multi-finger step, choose Show result.
?Does it work on a computer without a touch screen?
No. The mouse is not measured in this test, so the grid does not fill in. Open it on a laptop, tablet or phone that has a touch screen.
?What does the multi-finger step look at?
It shows, as reference only, the largest number of touches the browser recognised at the same time when you put several fingers down. It is not used for the judgement.
?Is the result proof for an exchange or warranty claim?
No. The result is a reference measurement based on signals your browser receives and on what you confirmed yourself. Follow the seller’s or manufacturer’s rules for exchange and repair.

Cells never touched

Most simultaneous touch points
Cells never touched that call for a check
Wipe the screen with a soft dry cloth, dry your hands and measure again. Moisture or grease can disturb the response.
Check that a screen protector or case is not lifting or too thick, take it off and measure again.
Restart the device and measure again.
Check for updates to the operating system and the touch driver. Also look at touch settings such as a glove mode.
If it still happens, check the seller’s or manufacturer’s exchange and warranty terms.
Press Start to rub the grid below.
Rub every cell with your finger. A cell changes colour once it is touched. Cover the edges and corners too, then press “I rubbed every cell”.
Put several fingers on the grid at the same time. The largest number of touches recognised at once is shown.
Cells that were not touched are hatched. Rub them again to clear them. Try the multi-finger step or press “Show result”.
