Google has released Android 11 for most of the Pixel series today (September 8, 2020). Shortly after that event, OnePlus stated that it was ready to start pushing the same new OS version to its current premium smartphones, the 8 and 8 Pro.
Therefore, users with these devices can download the first OxygenOS Open Beta based on Android 11. Some of them may be very familiar with such a ROM already, however, as the OEM has also had access to its Developer Previews. It has released several versions of these for the same flagships.
OxygenOS Open Betas, on the other hand, are often virtually stable builds that are open to the general 8-series-owning public. Those who move to this OTA channel will encounter a version of Android with a new 11-style UI.
It also has a new Story mode in its native Gallery app, and an updated Zen Mode with new themes and functions. Then again, there is no Always-on Display as yet. Users wishing to upgrade to this latest version of Android can do so by following the instructions on the official OnePlus community website.
