Over the past weeks, OnePlus has rolled out the February 2022 security update to several smartphones, including the OnePlus 7 series, OnePlus 7 series, OnePlus 8 series, and OnePlus Nord 2. However, the company's top-of-the-line flagships — OnePlus 9 and OnePlus 9 Pro — were peculiarly left out. That's finally changing as OnePlus has just announced a new update for both phones that brings the February patches, among other things.

OnePlus has started seeding a new OxygenOS 12 update (firmware version C.46) to the OnePlus 9 and OnePlus 9 Pro. As far as changes and improvements are concerned, the latest update improves the system stability and fixes several bugs, including an issue with Always-on Display, random crashes of the Alexa app, and an issue related to 5G connectivity. And of course, the release also bumps the security patch level to February 2022.

At the moment, we don't have access to the firmware package for the European variant of the OnePlus 9 and OnePlus 9 Pro.

Notably, OnePlus hasn't released this build for the global variant "due to specific country-related limitations."
