We have been hearing about the merger of OxygenOS and ColorOS for some time. The new merged unified OS platform will arrive with the upcoming Android phone releases from Oppo and OnePlus. However, if you are enrolled in the OnePlus Developer Preview program on your existing OnePlus 9 and 9 Pro, you can see the new release arriving for your phone. OnePlus is going to release the Android 12 with a new unified platform once it's stable. The new platform has many UI elements and traits belonging to the OxygenOS but it seems more notable to ColorOS than the previous OxygenOS 11 software.
