Names vary by country: DeviceAtlas lists all three codes as the Y91, and the Snapdragon 439 Y91i sold in the Philippines and Malaysia is reported under vivo 1816. Not the India Y91i (vivo 1820). Ships with Funtouch OS 4.5 (Android 8.1) per vivo Indonesia spec page. Release month: released in Indonesia in November 2018 per a vivo-backed Indonesian article (India launch January 2019 per MobiGyaan). No Android update is documented, so this is the version it shipped with.
The app can't run on the vivo Y91 / Y91i
Its last official update is Android 8, 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.
