If you are a developer with a supported Google Pixel device, you can manually update that device to the latest build for testing and development. This page helps you download an Android 12 Developer Preview system image and flash it to your device. You'll need to do a full device reset, so make sure to back up your data first. 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 flashed 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 flashable 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.
Flash your device using the Android Flash Tool
Android Flash Tool lets you securely flash an Android 12 Developer Preview system image to your supported Pixel device. Android Flash Tool works with any Web browser that supports WebUSB, such as Chrome or Edge 79+.
The Android Flash Tool guides you step-by-step through the process of flashing your device—there's no need to have tools installed—but you will need to unlock your device and enable USB Debugging in Developer options.
Connect your device over USB, then navigate to the Android Flash Tool and follow the onscreen guidance. For complete instructions, see the Android Flash Tool documentation.
Flash your device manually
You can also download the latest Android 12 preview system image and manually flash it to your device. See the table below to download the system image for your test device. Manually flashing a device is useful if you need precise control over the test environment or if you need to reinstall frequently, such as when performing automated testing.
Once you back up your device data and download the matching system image below, you can flash the image onto your device.
You can choose to revert to a production build at any time.
