Latest updates

Hello Nokia X20 Android developer preview fans!

• Update 15 June 2022: A new ADP Beta build (ADP2 - V3.080) with June 2022 Security Patch is available for you to test your apps.

Important notes

Please review the points below before proceeding with the registration process:

• Nokia X20 is currently the only supported device within the Nokia phones Android 13 developer preview program.
• Android 13 developer preview program builds (ADP) are early Android OS releases and are intended for application developers only – they are not recommended for general use.
• Although strenuously tested by our development team, these builds, and some applications downloaded from the Google Play Store, may exhibit performance and/or stability issues.
• Upgrading to Android 13 and rollback to Android 12 will result in loss of user data - we recommend you back up any user data to avoid potential loss.
• Online support is limited and may not be available to support users who experience difficulties with flashing the device.

If you have any doubts as to whether these builds are suitable for your use, we recommend you do not continue with developer preview registration and await the official market release.

Note:

Please note, we may not be able to offer Android 13 developer preview program builds to devices on certain network providers.

Ready to get started?

• Open the My Device app on your device, click on the Support banner at the bottom, and scroll down to “Android developer preview”.
• Allow the app to check your device IMEI (so we can check device eligibility), agree to the software license terms and conditions, and after checking the Important Notes, confirm you’re happy to continue.

Get developer preview over the air

Over-the-air (OTA) is the easiest way to get your hands on the new Android developer preview builds. Due to image file size, it is recommended that users download builds over Wi-Fi.

Please remember that installing an ADP build will result in the loss of user data. We recommend that you back up any important data before requesting the build.

After you request the update, we'll push the build to you within 12 hours and you'll get a notification on your device when the build is ready to install.

Alternatively, if you want to try and get the build sooner, wait about 20 minutes after requesting the build (so we can get the build synched with your IMEI) and then try a manual push request from Settings > About Phone > System Updates.

After installing, you can go ahead and test your apps. Don't forget to let us know what you think – you’ll be helping with software improvements and enhancements later down the line.

Please report any issues through the pre-installed Customer Feedback app as this is the quickest way for us to receive your issues for further review.

Also, feel free to discuss your experiences with other developer preview users in the Nokia phones community.

See Nokia phones Android developer preview license terms.

Rollback to official release

We really hope you’ll continue with the Android 13 developer preview program and provide feedback through the Feedback app, but if you’d prefer to return to the official release software, you can do so by requesting a rollback through the My Device app.

Advisory notice:

• Please remember that rollback to an official market release will result in the loss of user data. We recommend that you periodically back up any important data such as contacts, call logs, pictures, videos, music, installed apps, chat history, SMS history, notes, etc. You may also need to re-install any applications previously downloaded.
• Ideally, your phone should be fully charged, but a minimum of 60% charge is recommended.
• Please note you will not be able to use the phone – including any attempts to make an emergency call – until the installation is complete and the phone has booted into a stable state.

You’ll still be a member of the Nokia phones developer preview program and be able to request Android 13 developer preview program builds should you so wish.

Unregistering

If you wish to unregister from the Nokia phones Android developer preview program, you must first roll back all devices in your account to the latest general release Android version.
