Browser compatibility
Feature detection decides whether each test can run. A missing API means the browser does not expose it—not that the device is broken.
Chrome, Edge, Firefox, Safari, Chrome on Android, and Safari on iOS expose different capabilities. Secure HTTPS is required for many media and sensor APIs.
For the best result, use an up-to-date browser, review site permissions, and compare another browser when a feature is unavailable.
