Ships with EMUI 9.0.1 (Android 9) and Google Mobile Services; install the EMUI 10 (Android 10) update first. The B codes are the P30 lite New Edition (2020), MAR-LX2J the Japan model and HWV33 the au P30 lite Premium. The China model is the nova 4e. 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.

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.
