OnePlus' Head of Product Oliver Zhang also told the publication in the interview that end-users will still get the use OxygenOS as it is. There will be no major UI changes, but we can't say the same for some behind-the-scenes stuff. Nonetheless, the executive assured that users won't be able to tell the difference between OxygenOS 11.3 and vanilla OxygenOS. Consolidating the OxygenOS and ColorOS codebases makes it easier for OnePlus and OPPO to jointly develop software. The remaining OnePlus devices' software will use the new integrated codebase with the Android 12 update, which, at this point, is still quite some time off.
OnePlus could even 'borrow' some ColourOS features and bake them into future OxygenOS builds. Then again, Chinese OEMs freely draw inspiration from each other, and at this point, just about every Android fork made by a Chinese OEM has more or less the same feature set.
