Welcome Android 12! As you may have read earlier in the morning, there is a new preview of Android for developers! The latest versions of Android have focused more on refinement than on the complete redesign of the OS, and this trend apparently continues with Android 12 Developer Preview.
Google says its main goal is to make Android 12 “more intuitive, more efficient and safer.”
As you might expect with a first preview, Android 12 Developer Preview is aimed only at developers and is a very early version. In other words, I would advise you not to try it unless you have a secondary device at your fingertips, as it is certainly too buggy to be used as a daily pilot. For those with a spare Pixel smartphone, your only choice at the moment is to manually download and apply the update. Although using a factory image is usually the default method, I recommend you wait for OTA images.
Although you still have to install it manually, using an OTA image doesn’t require you to completely erase your device. Of course, if you’re a developer and want to use the cleanest method, factory images may be preferred.
The current preview for Android developers is only compatible with Pixel smartphones from the Pixel 3 series. Here are the prerequisites:
- A Pixel 3 or higher compatible device and a USB cable to connect it to your computer.
- The Android SDK installed on your machine with and control
Now, the steps to follow.
Download the appropriate files to install Android 12 Developer Preview
You need to download the appropriate file for your device before you start. I recommend using OTA images instead of factory images, as the process is easier to complete and allows you to keep old files if you’re interested.
Click here to get the OTA image for your Pixel device. It is also possible to use the complete factory images(here), but this requires additional operations, such as unlocking the bootloader and much more. Again, if you want things to stay simple, I recommend you load the OTA images.
