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 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”. You’ll have to perform a web search or look up a list of Android codenames if you want to know the code name associated with the version. Here’s a current list:
- 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.
Build number and Kernel version give you information about the exact build of Android on your device and its Linux kernel version and build date. Traditionally, this information has been helpful in determining whether your device has the latest security patches. In Android 6.0, Google added an Android patch security level field here that tells you when your device last received security patches.
