It is better late than never. That is what many people will say if something important has been delayed. For ASUS, the older ROG Phone II took awhile before it receives Android 11. It’s ready now and we still hope it will still be able to get Android 12. It was over a year ago, when the ASUS ROG Phone 2 started receiving the Android 10 OS update.
