What devices can be tested?

The Device Test Center supports browser-accessible hardware on phones, tablets, laptops, desktops, MacBooks, Chromebooks, all-in-one computers, smart TVs, monitors with built-in cameras or speakers, and connected USB or Bluetooth accessories.

What cannot a browser test?

A browser can only test hardware and information exposed by the operating system and browser. A standard LCD, LED or OLED panel has no camera unless one is built in. Some smart TVs and corporate devices block camera, microphone, location or sensor permissions.

Privacy by design: Camera previews, microphone recordings, touch input and most diagnostic results stay in your browser unless a page explicitly states otherwise.
