About Device tests tools
Check that your hardware works before a call, a game or a purchase. Hear your microphone and watch its level, see your webcam’s picture, resolution and frame rate, press every key to test a keyboard, fill the screen with colours to spot dead or stuck pixels and see your screen resolution. Then test yourself: your typing speed in words per minute, your clicks per second and your reaction time. Camera and microphone tests run entirely in your browser, so nothing is recorded or uploaded.
Frequently asked questions
Is my camera or microphone recorded?
No. The picture and sound are only shown on your screen and are never recorded, saved or sent anywhere. They stop as soon as you leave the page.
Why does my browser ask for permission?
Browsers always ask before a site can use your camera or microphone. Allow it to run the test; you can take the permission back at any time in the browser’s site settings.
Do the tests work on a phone?
Most do. The mic, webcam, screen, dead pixel, reaction and click tests work on phones and tablets; the keyboard and typing tests need a physical keyboard for the best results.
