What is What Version of Android Do I Have?
Reads the Android version straight out of your browser's user agent string — a quick check without digging through Settings. Useful for quickly checking compatibility with an app or feature that requires a minimum Android version. The check runs entirely in your browser, nothing is sent to a server — but since it depends on what your browser reports, it's a quick reference, not a guaranteed-accurate system report.
FAQ
Either you're not on an Android device, or your browser sends a generic user agent for privacy, which is increasingly common.
No — it shows the Android version number reported in the user agent (e.g. 13, 14), not the manufacturer's specific build or security patch level. Check Settings > About phone on the device for that detail.
