The Huawei Mate 9 has started getting a new update in the US. Currently hitting GSM networks-compatible International unlocked units in the region (MHA-L29 and L09), it's major update that brings along Android Oreo.
The change-log for the update isn't yet available, although we assume all major Oreo goodies should be included. As is usually the case with OTA roll outs, it may take time for the update to hit your device, if not already.
did you get update ?
I'm in the U.S. and still waiting to see the Oreo update. I'm using a Mate 9, dual sim, on T-Mobile. Anyone else in the U.S. seen it yet?
Mate 9 MHA-L29 middle east variant is C185, but still there is no official update available as of yet.
