Message for the EMUI 9.1 Open Beta Version Testers
Huawei officially reminds that some third-party applications are not compatible with Android 9.0. Therefore, after the upgrade, third-party applications may not be able to be used normally (such as flashback, freeze, power consumption, etc.). It is recommended to try this in Huawei APP store and apply updates to the latest version.
In addition, users who sign up for the beta event ensure that the current mobile version is on the baseline version of the subscription. One can view the version number by going into Settings -> About view the version number information, if you are not currently on the baseline version, please upgrade to this version first.
Looks like it’s only Huawei which is providing updates even to 3 years old Mate 9, P10, Honor 10 with EMUI 9.1 based on Android 9.0.
