Just a day after Google has released the Android 11 Beta 1 for all the Pixel users, OnePlus has gone ahead and done the same, becoming the first non-Google company to bring the update to their devices. At the moment, the update is available on OnePlus 8 and 8 Pro.

OnePlus is releasing the Android 11 Beta 1 as a part of their Developer Preview program. It will help the app developers, as well as early users, get started on creating new apps for the upcoming version of Android as well as OxygenOS.
