Why does my browser ask for microphone permission?
A live microphone test needs access to your microphone. Permission is requested only after you press Start Microphone Test, and you can stop at any time.
Why does my browser ask for camera permission?
The webcam preview needs access to a camera. Permission is requested only after you start the webcam test.
Can I use QuickDeviceTest on mobile?
Yes. The site adapts to phones and tablets. Keyboard and mouse tests work best with physical input devices; some mobile browser features may be limited.
Which browsers are supported?
Use a current version of Chrome, Edge, Firefox or Safari. Available capabilities depend on your browser, operating system and hardware. Camera and microphone tests require HTTPS or localhost.
Why isn’t my device detected?
Check that it is connected, allow the relevant browser permission, and close other apps that may be using it. Try another cable, port or browser if the problem continues.
