How it works and what the result means

Understand the test before interpreting a number. A web page only sees the information exposed by your browser. It cannot read every physical hardware property.

Use a visible foreground tab, close heavy background apps and keep browser zoom and device settings consistent. If a permission-based test does not start, use HTTPS and check browser site permissions. Some mobile and privacy-focused browsers do not expose every device API.
