Touch Screen Test
Check your touch screen registers every touch. Draw across the screen with your finger and any dead zone shows up as a gap where the line breaks. Press with several fingers at once to test multi-touch, and watch each point tracked live with its coordinates. Works on phones, tablets and touch laptops.

Drag your finger across the whole area. Gaps in the line are dead zones. Use several fingers to test multi-touch.
How to use it
- 1
Draw across the whole screen
Drag your finger over every part of the test area, edge to edge. A smooth, unbroken line means the digitiser is reading that region.
- 2
Look for gaps
A dead zone shows up as a spot where the line breaks or your touch is not picked up. Cover the corners and edges, where faults often hide.

Test multi-touch
Place several fingers down at once and watch each one tracked as a separate point. This confirms the screen handles the gestures apps rely on.
When it comes in handy
After a cracked screen
Check whether a drop or crack has killed touch in part of the display, even if the picture still looks fine.
Buying a used phone or tablet
Sweep the whole screen before you buy, so a dead strip along an edge does not turn up after the sale.
Multi-touch and gesture checks
Confirm the screen registers two, three or more fingers, which pinch-to-zoom and other gestures depend on.
Instant & 100% private — nothing is recorded
The test runs right here in your browser. When it needs your camera or microphone, the feed is shown to you and nothing else: never uploaded, never recorded to a server, never stored. There is no sign-up and no email wall, and most tests keep working with no connection at all.
Frequently asked questions
- How do I find a dead zone on my touch screen?
- Draw slowly across the whole screen in overlapping passes, including the very edges and corners. Anywhere the line breaks or your finger stops being tracked is a dead zone. Comparing it to a known-good area helps; a true fault repeats in the same spot every time you cross it.
- How many touch points can I test?
- The test tracks as many simultaneous touches as your screen reports, which is usually five or ten on modern phones and tablets. Place that many fingers down at once and each appears as its own labelled point. Fewer points than expected can mean a hardware limit or a fault.
- Does this work with a stylus or only a finger?
- It works with anything the screen treats as a touch, including most styluses and capacitive pens. Pressure and tilt are not shown, but the position of each contact is tracked the same way as a finger, so you can still map dead zones and check tracking with a pen.
- Does this test send anything to a server?
- No. The whole test runs in your browser on your own device, and nothing it reads is uploaded, recorded or stored. You can prove it by disconnecting from the internet after the page loads: the test keeps working. There is no sign-up and no account.
