How to install the Android 12 Developer Preview


Earlier today, Google released the first Android 12 Developer Preview for owners of devices ranging from the Pixel 3 and going all the way up to the Pixel 5. With traditional software updates, you would be able to install the new software just by using the Software Updates feature in the Settings app. However, with developer previews, things are a bit different as you’ll need to “flash” Android 12 to your Pixel. We’ve assembled a walkthrough on the various ways you can install the first Android 12 developer preview today.
