Quick checks before you visit a repair shop
Many phone and laptop problems, such as a muffled speaker, a mic that does not pick up your voice, a key that types twice or a screen that taps by itself, can be checked in a minute in the browser. These tests help you see whether the hardware works, so you can explain the problem clearly at a service centre.

Frequently asked questions
Do these tests record or upload anything?
No. The mic test plays your recording back only on your own device and never uploads it. All tests run inside your browser.
Why does the vibration test not work on my iPhone?
Safari on iPhone does not let websites use the vibration motor, so the vibration test works only on Android phones and some other browsers.
