The popular OnePlus 9 Series has recently bagged the stable Android 12-based OxygenOS 12 firmware. However, the update wasn’t a big hit among the OnePlus community as it was full of bugs and glitches. Although the stable Android 12 update was released, it seems like it isn’t stable yet. There are many issues related to the black screen, battery drain, unusable refresh rate, standby battery drain, and other performance issues.
While users have been advised to wait for some time to install the OTA update, if you’ve already upgraded your OnePlus 9 Series device to OxygenOS 12, you’ll want to rollback. You can downgrade your OnePlus 9, OnePlus 9 Pro, or OnePlus 9R from Android 12 to Android 11. In this article, you’ll get to know how you can do that without any issues.
