Back in October, Huawei began sending out invitations to an Oreo beta for the Mate 9. We're at the end of January now, and the US-compatible Mate 9 is finally receiving its official update to Android 8.0 Oreo. Some international models have had Oreo for some time now, but those of us in America are only just getting it.
Wow I really just ate my words. I just got the Oreo notification on my US #mate9 .

The update carries version number MHA-L29 22.214.171.1240 in the US (it might vary slightly for other countries) and weighs in at a whopping 2.71GB. New features include the standard Oreo stuff like picture-in-picture, dynamic icons, and Autofill, as well as device-specific additions such as EMUI 8.0, a floating navigation bar, a Dynamic Wallpaper feature, and so on.
