Announced at MWC in February 2018. Ships with Android 7.1.2; T-Mobile's Aristo 2 Plus was reported to get Android 8.1. Google Play lists these codes as K8 (2018) and K9. The US versions Aristo 2 (MetroPCS, from January 2018), Aristo 2 Plus (T-Mobile), Tribute Defiant (Boost) and K8+ (US Cellular) are the same phone, but their Build.MODEL was not confirmed, so check the detected code. Fortune 2, Phoenix 4, Zone 4, Rebel 4, Tribute Dynasty and the Korean X2 have their own codes. No built-in gesture or key opens a chosen app.

The app can't run on the K8 (2018) / K9

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.
