From when oneplus 9R will get Android 12 update?
OnePlus never gives ETA's on updates, so there's no way of knowing when you will get Android 12. First Google has to release it, which it hasn't yet, and then you'll have to wait until it's your device it's turn.

Android 12 is still under development by Google. Once it is released OnePlus will start working on an oxygen os version based on it. There is no ETA.
