OnePlus recently announced an Android 12 developer preview program for its flagship OnePlus 9 series. Since the announcement, OnePlus has already released (and subsequently pulled) the first Android 12 beta for the OnePlus 9 and the OnePlus 9 Pro. However, it hasn't announced a similar program for the OnePlus 9R. Instead of an Android 12 beta build, the cheapest phone in the OnePlus 9 lineup is getting an incremental OxygenOS update based on Android 11.

The latest OxygenOS update for the OnePlus 9R (v11.2.1.2) has started rolling out to users in India. It brings a ton of bug fixes and improvements, along with the Android security patches for May 2021. Here's the complete changelog for the new OxygenOS update for the OnePlus 9R:

  • System
    • Fixed the abnormal silent notification issue after muting the media volume
    • Fixed UI issues in Freeform Windows
    • Fixed general issues and improved system stability
    • Updated Android security patch to 2021.05
  • Notes
    • Fixed the issue that newly saved notes can't sync to Shelf in time
  • OnePlus Games
    • Improved the overall user experience
  • Gallery
    • Improved picture preview smoothness
  • Camera
    • Improved the camera stability and shooting performance
    • Fixed the abnormal image issue under Nightscape mode

As with all incremental updates from OnePlus, OxygenOS 11.2.1.2 for the OnePlus 9R will initially roll out to a handful of users. After OnePlus confirms that it doesn't have any major issues, it should roll out to more users. If you don't want to wait for the OTA update though, you can download the incremental update package from the link below.
