This page provides links to over-the-air (OTA) Google Pixel device images and describes how to apply an OTA update to a supported device. Applying an OTA image has the same effect as flashing the corresponding factory image, but without the need to wipe the device or unlock the bootloader. You can also apply an OTA image to recover a device that received an OTA update for an Android 12 Developer Preview build but does not start up after the update is installed.
Android 12 Developer Preview builds are only available for the following Google Pixel devices:
- Pixel 3 and 3 XL
- Pixel 3a and 3a XL
- Pixel 4 and 4 XL
- Pixel 4a and 4a (5G)
- Pixel 5
After you've installed a Developer Preview build to your Pixel device, you'll automatically be offered over-the-air updates of later preview builds. We'll also deliver OTA images at each milestone, so you can choose the approach that works best for your test environment.
Use the links and instructions below to update your supported device to the latest milestone build for your device. See Get Android 12 for other ways to get Android 12 for testing and development.
Apply an OTA image
Download an OTA device image from the table below and apply it by following the updating instructions listed on Full OTA Images for Nexus and Pixel Devices.
You can choose to revert to a production build at any time.
