Frequently Asked Questions
Why do some fields say unknown or unsupported?
Because the page can only report what the browser exposes. APIs like Battery, connection details, deviceMemory, and even some hardware info are missing or privacy-limited in many browsers.
Does the snapshot update automatically, or do I have to refresh it?
It updates when you click Refresh, and it also rerenders on window resize plus online/offline events. That helps viewport and network status stay current.
What exactly gets copied when I click Copy JSON?
The button copies the last collected snapshot object stored on window.__deviceInfoSnapshot. That includes browser, OS, screen, network, hardware, language, timezone, features, and battery data when available.
Can this identify the exact device model?
Usually no. Most of the output is browser-exposed metadata plus simple UA regex detection, so it is much better for environment diagnostics than for exact device fingerprinting.
Why does the Battery section just say Unsupported?
That happens when navigator.getBattery is unavailable or blocked. In those browsers, the tool falls back to a Battery API unsupported message instead of guessing.
