This check runs through every essential part of your device — camera, microphone, speakers, keyboard, touch sensitivity, and network connectivity. It takes about three minutes.
Nothing is saved. Any audio or video captured during the test is processed entirely in your browser and discarded the moment the check ends. We use it only to confirm your hardware is working.
By starting, you agree to grant temporary access to your camera, microphone, and other device sensors so we can verify they're functioning.
