T773O

Build.MODEL T773O (Google Play device list). Released 2021-05 per PhoneCompass. Ships with Android 11; TCL committed at least one Android upgrade (9to5Google), but no rollout was found. Its user manual (Bell) lists no Smart Key; Fingerprint Quick Launch opens a panel of up to four apps rather than one chosen app, so it is not listed. No built-in gesture or key that opens a chosen app is documented; use the common inputs.

    Two taps on the home-screen widget within 3 s; a single accidental tap does nothing.

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.
