If you have already flashed any (newer) OxygenOS Open Beta firmware on OnePlus 3/3T, you’d be getting this update without any further ado. But keep in mind that once you flash this Open Beta firmware on OnePlus 3/3T, you will not be getting the official regular stable OTAs, that means, you may have to manually flash the newest stable firmware on the device.

Last but not the least, moving back to the Official OTA path from the Beta path will require a full install and clean flash which might possibly erase everything on your device. So if you’re not sure about the consequences, you’re not supposed to try the Open Beta firmware on OnePlus 3/3T.
