What is a touchscreen tester?
A touchscreen tester shows each point your screen registers as you touch it. It helps you check multi-touch, find areas that don't respond, and spot ghost touches, where the screen reports a touch that did not happen.
See also the device testers, including Screen Tester and Mouse Tester.
What to look for
- Each finger should produce one numbered circle that follows it, with nothing extra.
- The "Most at once" count should match the number of fingers you use, up to the device's reported limit.
- A circle that appears when nothing touches the screen is a ghost touch. Clean the screen and check again.
A mouse or a touchpad shows one point. The device limit is what the browser reports, and in practice the number of points a screen can track may be lower.

Questions.
How many fingers can the touchscreen track?
The tester shows the limit your device reports. The number of fingers it can track at once may be lower in practice, depending on the hardware and the browser.
Why does a mouse show only one point?
A mouse and a single-finger touchpad send one pointer at a time, so one touch point is correct for them.
What is a ghost touch?
A ghost touch is a point the screen registers when nothing is touching it. If you see circles appear on their own, clean the screen, remove any case or screen protector that might cause it, and test again. Repeated ghost touches can mean a faulty screen.
Does this test the touchscreen's accuracy?
It shows where the screen registers each touch, which is useful for spotting dead or missing areas. It does not measure exact positioning in millimetres.
Can I test a trackpad with this?
A trackpad sends one pointer at a time, so it shows one point. Use the mouse tester to check its buttons and scroll.
