This is a Software update for the OnePlus 9R and not the major/stable OS update as it already has an Android 11 OS.
The OnePlus 9R will receive three years of major OS updates and four years of Security updates.
Therefore, Android 12 will be the first major OS update on this device and it is also eligible to be on the Android 13 and Android 14 update list as well.
