The basic steps for finding out which version of Android you’re running, are the same on all devices. Depending on your specific version, things may look a little different though.
The end goal is to get to Apps > Settings > About
Many devices have a shortcut to get to Settings. Swipe down from the top of your screen, no matter which screen you’re on and you should see the Settings icon. Tap that to get right into the settings screen.
Alternatively you can tap the All Apps icon from the homescreen, then search for or scroll down to Settings.
Scroll down until you see About. You may see your version number there, or you may have to tap that.
Then tap Software information.
This will show you the numbered version of the release you’re on.
Android version names
In addition to numbered releases, Android also gives their releases cute, dessert-y names. Often you’ll see the version referred to only by name and not number, so to find the list of releases by name and number go here.
