Ships with EMUI 10.1 (Android 10). No Google Mobile Services (Huawei Mobile Services and AppGallery instead): the Android-based OS may still run our APK, but Google Assistant routines (android-voice) are not available. No built-in gesture or key opens a chosen app: knuckle gestures (where present) only take screenshots or record the screen, and double-pressing Volume down only takes a photo or opens the camera. Same phone as the Y7a. Release month is the announcement.

Gestures on the P smart 2021

No gesture specific to this model is known. We only list what the manufacturer or reliable sources document.

Plus what the app offers on every Android phone: In-app button, Widget, Quick Settings tile, Shake, Volume keys, Voice phrase. How to set those up

Recommended presets

  • Shake ×3Sends a signal

    Three sharp shakes within 2.5 s: hard to do by accident, easy to do without looking.

    Shake ×3, 0.15–1 s apart · whole gesture within 2.5 s

  • Widget ×2Sends a signal

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

    Widget ×2, 0.1–3 s apart · whole gesture within 3 s

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.
