Yes. The touch screen test works on any device with a touchscreen and a modern browser — iPhone, Android phones, tablets, and touchscreen laptops. No app needed.

A dead zone is a spot on the screen that doesn't respond to touch. It can be caused by physical damage to the digitizer, software glitches, or hardware failure. Our test highlights dead zones in red after you swipe across the screen.

The test divides your screen into a fine grid and tracks which zones your finger passes over. Accuracy depends on your device's digitizer sensitivity and how thoroughly you swipe across the screen.

Start by cleaning your screen and removing any screen protector, then restart your device and retest. If dead zones persist, check for a software update. Ongoing dead zones usually mean a damaged digitizer that needs professional repair.

No. This test only reads your screen's touch input. It doesn't access your camera, microphone, contacts, or any other device data. Everything runs locally in your browser.

Yes. You can place multiple fingers on the screen at the same time. Each finger is tracked independently, letting you quickly cover the grid and confirm your device handles multi-finger gestures correctly.

Make sure you're touching the screen directly — not using a mouse or trackpad. If the grid doesn't respond, try restarting your browser, clearing the cache, or switching to a different browser. If nothing works, your device's touch hardware may be faulty.

During the test, device info including the maximum number of simultaneous touch points is shown on screen. Most modern smartphones support 5 or more simultaneous touch points.

Yes. The test works on Windows touchscreen laptops. Open the page in your browser, switch to touch mode if needed, and swipe across the display to check responsiveness.

It can. A thick, poorly fitted, or cracked screen protector may reduce touch sensitivity or create false dead zones. For the most accurate result, remove the screen protector before running the test.

100% coverage means your finger reached every zone of the test grid and the screen responded correctly everywhere. This is the ideal result and confirms a fully working touchscreen with no dead zones.

Yes. Tap the camera icon during or after the test to grab a screenshot of your results. Download and share the image with a repair shop or attach it to a warranty claim.

No. The entire test runs locally inside your browser. No touch data, device information, or test results are sent to any server. Your privacy is fully protected.

A basic check takes about 30 seconds. For a thorough test of all edges and corners, allow 1–2 minutes. Use fullscreen mode and multiple fingers to speed things up and get more complete coverage.
