Ships with EMUI 4.1 (Android 6.0) and Google Mobile Services. Huawei's open-source releases for BLL stop at Android 6.0; an Android 7.0 update was reported for some markets but is not confirmed, so last_os counts the lower version. BLL-L23 is the Latin America Mate 9 lite. The Honor 6X is the same phone with BLN codes.

The app can't run on the GR5 2017 / Mate 9 lite

Its last official update is Android 6, and the app needs Android 10 or later.

Gestures are set up in the phone settings as shown, then combined into a trigger recipe in the app, where practice mode shows step by step whether a gesture would trigger.
