    Hey everyone,

    The Android 12 Developer Preview 2 is now available for the OnePlus 9 and OnePlus 9 Pro!

    By providing access to Developer Preview at an early stage, we enable app developers and other early adopters in our community to start creating even better software experiences. For more information, please refer to

    As the name suggests, this build of Android 12 is best suited for developers and other advanced users, as it is still in an early stage of development. That said, we do not recommend flashing this ROM if you have little to no experience in software development, if you expect to use the device as a daily driver, or if you have no experience flashing custom ROMs. Proceed at your own RISK!

    Update: Due to stricter EU policies, we currently cannot supply an EU-specific build. However, as @derLenno already shown above, installing the NA build works if you want to test out the Developer Preview ahead of the Open Beta builds.

    We have provided an EU rollback build for your convenience.

    Don't bother, too many known issues and probably even more unknown...

    edit:
    + Open beta probably in a few weeks
    + To go from this to Open beta will probably delete all your data -> again.

    Hey everyone,

    Thank you for the questions from our European users regarding the lack of an European-specific build. I've already contacted the software team about this and I will update you guys as soon as possible.

    Thank you for your patience.
