Start testHow these tests work
Open a test and click Start when you are ready. Each test requests access only to the device it needs. You can stop at any time. Video and audio stay in your browser; snapshots and recordings are downloaded only when you choose.
These tests help you check what your browser can access. They do not diagnose every hardware or driver problem.
