About the Touch Screen Test
The Touch Screen Test drag your fingers across the panel to find dead zones, and see how many simultaneous touches your screen supports. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Finding a dead patch on a phone or tablet digitiser before a warranty runs out.
- Checking a repaired or replaced screen.
- Confirming multi-touch after a driver update.
Frequently asked questions
How do I find a dead zone?
Go fullscreen and drag one finger slowly over the entire surface in overlapping passes. Where the trail breaks or the dot jumps, the digitiser is not reading. Cover the edges and corners too, which is where damage usually starts.
How many touches should my device support?
Modern phones report five or ten, and most tablets ten. The figure your browser reports is shown in the results.
My screen works but ignores my finger in one corner.
That is a classic digitiser fault, often from a drop or from moisture under the glass. A screen protector with a trapped bubble or a thick case pressing on the edge can cause the same symptom, so try removing both first.
Is there a limit on how often I can use the Touch Screen Test?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Can you see what I put into this tool?
No. The Touch Screen Test runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
Who is the Touch Screen Test for?
The jobs it is built for: finding a dead patch on a phone or tablet digitiser before a warranty runs out. Checking a repaired or replaced screen. Confirming multi-touch after a driver update. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Does the Touch Screen Test need an app or a driver?
No installation, no extension and no driver. The Touch Screen Test uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
