How to Check Which Android Version You Have

An app says it needs a certain Android version, or a support page asks which one you have. The number is two taps into Settings.

Open About phone

Open Settings, scroll to the bottom, and tap About phone.

Read the Android version line

Look for Android version near the bottom of the About phone screen. The number next to it, such as 14, 15, or 16, is your version. On Samsung, tap Software information first; the Android version line is on that screen, alongside the One UI version.

Tap Android version for details

Tap the Android version line to open a details screen with the Android security update date, the Google Play system update date, the Baseband version, and the Kernel version. The security update date matters as much as the version number when a support article asks how current the phone is.

Check for a newer version

Go back to Settings, tap System, then Software updates, then System update. The phone checks with Google and offers a download if one is waiting. On Samsung, the path is Settings, Software update, Download and install. Updates arrive on a schedule set by the manufacturer and carrier, so a phone that says it is up to date may still be a version behind the newest release.

One UI is not Android. Samsung shows two numbers. One UI 7 or 8 is Samsung's interface layer; the Android version underneath is what apps and support pages care about. One UI 7 runs on Android 15 and One UI 8 on Android 16.

If you tap Build number by accident. Tapping Build number seven times turns on Developer options. This changes nothing on its own. Ignore it, or turn it off under Settings, System, Developer options.
