Touch Screen Test
The screen is split into cells that fill in as you touch them. Any cell that won't fill marks a spot the touch panel isn't picking up. You can drag your finger to paint a line, which also catches dead strips.
Touch
Press every cell and look for spots that do not respond.
Pick a check and run it right here.
For things like the screen, touch, sound and camera, look for yourself and press "Works" to record a pass.
Press Turn on microphone and your browser will ask for permission. Sound stays on this device and is never sent anywhere.
The recording isn't saved and is deleted when you leave this test.

Frequently asked questions
Are the very edges tested?
The grid sits inside the test area, so the outermost edge isn't covered. If the edges are suspect, try dragging an app icon along them on your home screen.
Does it work on a computer?
Clicking also fills cells, but to test a touch screen you need to use your finger.
One spot never fills.
If the same spot keeps failing, the panel may be faulty. Check first that a screen protector isn't lifting there.
