Nokia Mobile again launched the Android Developer Preview program for developers to early test the beta build of Android 12. The program is working only with Nokia X20, and it is primarily aimed at app developers, not for general use since it is the early beta build that might cause some software instabilities and apps to crash.
If you are a developer and an owner of the Nokia X20, or you are an adventurous person that likes to play with beta builds, you should know that the registration for the Android developer preview program and requests for Upgrade and Rollback builds are only available via the My Phone app on your device.
But, before you continue experimenting with new beta software upgrades, Nokia Mobile wants you to review the following points:
Android 12 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, the builds may exhibit performance and/or stability issues in some cases.
Some applications downloaded from the Google Play Store may not be supported (either in full or in part) and may show signs of instability.
Upgrading from Android 11 to the Android 12 developer preview program and rollback from the Android 12 developer preview program to the Official Android 11 build will result in loss of user data. As such, we recommended that you back up any user data to avoid loss.
Online support is limited and may not be available to help users who experience difficulties with flashing the device.
We also do not recommend downloading unstable beta builds of Android 12 if you are not an experienced smartphone user, or a developer that has an extra Nokia X20. But, if you do wish to get the update, you should open the My Phone app on Nokia X20, click on the Support banner at the bottom, and scroll down to “Android developer preview”. Allow the app to check your IMEI, agree to the software license terms and conditions, and after checking the Important Notes, confirm you’re happy to continue.
The update can be delivered Over-The-Air (OTA), and you are suggested to use WiFi connectivity since the file is super large.
Once you are done with testing the Android 12 Beta Build, you can request the rollback through the MyPhone app and get the stable Android 11. Bear in mind that during the process, all of the data will be erased.
Anyways, there you go. Nokia Beta Labs are back with the Android Developer Preview program for Nokia X20. For more info, do check Nokia phones Android 12 developer preview program page.
