A few days ago, we informed that the major update of the OxygenOS system to version 12 for OnePlus 9 and OnePlus 9 Pro phones causes serious errors for many users. These errors often made users almost unable to use their smartphones, hence OnePlus reacted to these reports by removing the system update from the Internet, at the same time announcing that it will be available for download again after correcting errors in the code. That moment has finally come.
OxygenOS 12 is now available for download for users of the aforementioned phones: OnePlus 9 and OnePlus 9 Pro. The new update has codename C.39, where the previous update had C.36 code in its name. OnePlus informed users about fixing previously occurring errors which could include, among others, freezing of the phone, no possibility to connect to cellular data or no possibility to answer a voice call. The update itself also introduced several other changes, such as improving the operation of the application for taking photos, but also improved speed of the fingerprint reader.
