Frequently asked questions
Does DeviceTest download anything?
No. The tools are designed to run in the browser. Camera and microphone tests require your browser's permission.
Can a browser test prove that my hardware is perfect?
No. Browser APIs can confirm what the browser detects, but they cannot diagnose every hardware or driver problem.
Why does my microphone or camera need permission?
Modern browsers protect camera and microphone access. You must explicitly allow access before a web page can use them.
