Update (05/25/2022 @ 08:00 ET): OnePlus initially published an incorrect changelog for OxygenOS C.60. Scroll to the bottom for more information. The article as published on May 19, 2022, is preserved below.

OnePlus is rolling out a fresh software update for the OnePlus 9 series, bringing a couple of multitasking and gaming improvements to the flagship devices. The update (version C.60) measures a little over 1.5GB and it packs improvements for the floating window feature, adds the HyperBoost end-to-end frame rate stabilizer, reduces game load time and power consumption, and more. However, the update doesn't bring the Android security patches for May 2022 to the OnePlus 9 and OnePlus 9 Pro.

According to screenshots shared on the OnePlus community forums, the latest software update for the OnePlus 9 series includes the following changes:

  • Convenience & efficiency
    • You can now open up to 3 apps in floating windows at the same time in Split screen mode and switch between Floating window and Split screen modes
    • You can now use the Clock app in Quick Return
  • Connectivity
    • You can now open up to 3 phone windows on your PC
  • Games
    • Adds the HyperBoost end-to-end frame rate stabilizer
    • Heterogenous graphics: Reduces gaming loads and power consumption (only for some games)

As with all software updates from OnePlus, OxygenOS C.60 for the OnePlus 9 series is rolling out in a phased manner. It should reach only a handful of users today, with a broader rollout to follow in the coming days. If you don't wish to wait for the OTA update, however, you can download the firmware package from the links provided below and flash the update manually.
