Device test questions

Does PetexSpace record my camera or microphone?

No. The camera and microphone tests attach the selected media stream directly to the page in your browser. The test does not upload or save that stream.

Why does a test show different information in another browser?

Browsers and operating systems expose different device details. A missing value means the browser did not make that detail available to the page.

Can a browser test prove that hardware is perfect?

No. These checks help reveal common input, output, pixel, and timing problems. Hardware faults can still require operating system tools or professional diagnosis.
