Frequently asked questions
Why is memory “—”?
deviceMemory is not in every browser — most common in Chromium.
What is DPR?
Device pixel ratio — how many physical pixels map to one CSS pixel. A value of 2 means a Retina-class display.
Why are model or architecture empty?
UA Client Hints work best in Chrome/Edge. On desktop, model is often blank.
Why is the USB list empty?
The browser does not scan every port itself — press Select and allow a specific device.
