Joining them are other 2017 models ? the Huawei nova 2s as well as the Honor 9 and Honor 8 Pro. These two, as well as the Mate 9 family started on Android 7.0 Nougat and will soon get Android 9.1 Pie. How?s that for software support?

All eight phones should be able to join the EMUI 9.1 beta right now. The stable release is probably a few months away (the Mate 20 started beta testing in April and got the stable release in late June).
