How to figure out which version of Android you have.
This information is available in Android’s system-wide Settings screen. Whatever version of Android you’re using and whatever customizations your device’s version of Android has, you should be able to get to it in the same way.
Open the “app drawer” — the entire list of apps installed on your phone. It’s almost always a button at the bottom of your home screen, in the center.
Scroll through the list of installed apps and look for an app named “Settings”. Tap the Settings icon to enter Android’s system-wide Settings app.
Scroll down on the Settings screen and look for an “About phone” or “About tablet” option. You’ll usually find this at the very bottom of the main Settings screen, under System.
Look for “Android version” to find the version of Android installed on your device.
It just displays the version number, not the code name — for example, it says “Android 6.0” instead of “Android 6.0 Marshmallow”. Here’s a current list of all Android Operating systems:
- Android 7.0: Nougat
- Android 6.0: Marshmallow
- Android 5.0 – 5.1.1: Lollipop
- Android 4.4 – 4.4.4: Kit Kat
- Android 4.1 – 4.3.1: Jelly Bean
- Android 4.0 – 4.0.4: Ice Cream Sandwich
- Android 3.0 – 3.2.6: Honeycomb
- Android 2.3 – 2.3.7: Gingerbread
- Android 2.2 – 2.2.3: Froyo
- Android 2.0 – 2.1: Eclair
- Android 1.6: Donut
- Android 1.5: Cupcake
Other fields here are also relevant. The “Model number” field tells you the name of your device, for example.
