Attention! With April patch, OnePlus 9 series will receive Oxygen OS

As we all know, OnePlus 9, OnePlus 9 Pro, and OnePlus 9R were announced on March 23, 2021. While the OnePlus 9 and the OnePlus 9 Pro will be available in global markets, the 9R is limited to India for now. We expect to see at least two major Android updates arrive on these models — Android 12 later this year, and Android 13 following in 2022.

Days after the phone launched, OnePlus pushed a day-one update to the OnePlus 9 and 9 Pro. Dubbed Oxygen OS for Indian variants and for global and European models, the update should be available to those who have preordered the devices. It’s clear OnePlus wants to give those who purchase the phone in week one a more refined experience.


Oxygen OS landed as the second update to the OnePlus 9 series on April. The update brought numerous improvements to the phones’ camera systems, a tweak to dark mode, and additional system improvements. The March 2021 Android security patch was also included.

The OnePlus 9 and OnePlus 9 Pro gained Oxygen OS on April. The third rapid-fire update touched on both phones’ system power consumption, and made improvements to the camera and network.
