Download Oxygen OS 12 HotFix Update for OnePlus 9 and 9 Pro (Android 12)

Earlier this month, Oneplus released the first stable OxygenOS 12 for their latest flagship phones OnePlus 9 and 9 Pro. However, the update didn’t turn out to be stable after all. The Android 12 OTA rollout was soon put on hold. Until today, a new stable Oxygen OS 12 HotFix OTA update is now available for download for OnePlus 9 and 9 Pro based on Android 12.

OnePlus came up with a HotFix update today with improved smoothness of fingerprint unlocking, improved performance, stability, and improved startup speed of certain applications. Most importantly, the OEM fixed failure to connect to the mobile data in certain scenarios, phone notifications not being visible, freeze issues, some display problems, etc.

Furthermore, OnePlus will release new features in upcoming updates such as the auto-fill feature in Chrome and the temporary lack of access to the Ultra HD 48M / AUX camera on GCam.

This update has reached a few users already and will continue to roll out incrementally. The new firmware is termed C.39. That’s how you distinguish the update from the previous C.36 update.

The latest update features all the Android 12 goodies like the new wallpaper-based theme engine, Privacy dashboard, Material You design, along with the latest Oxygen OS 12 firmware changes and updated OnePlus apps. Check out the complete changelog below.

Furthermore, OnePlus is also reported to have rolled out Color OS 12 for the Chinese variants of OnePlus 9 and 9 Pro; instead of the Oxygen OS 12. So you may not get the Color OS skin in the upcoming updates. Stay tuned for ColorOS 12!

Check out the complete changelog from below including the original one.
