Reno5 Lite / Reno5 F / A94 / F19 Pro

Requires: ColorOS 11 or later with Screen-off gestures switched on; touch panel support (OPPO says features vary by model)

Turn on the Screen-off gestures switch first, then tap a gesture under More (Draw ∧, Draw M or Draw W; ColorOS 16 defaults are Calculator, Gemini and Recorder) and choose our app as its action. The exact label of the app action on current ColorOS is not documented (ColorOS 6 called it 'Start an App'). Path on ColorOS 13.1-14.0: Settings > Additional settings > Gestures & motions > Screen-off gestures, where custom gestures are added with 'Add gesture' (ColorOS 12 manual: Settings > System settings > Gestures & motions; ColorOS 11 guide: Settings > Convenience Aid > Gesture & Motions > Screen-off Gestures > Add Screen-off Gestures, e.g. 'slide up to open the calculator'). OPPO's ColorOS 12 and 13.1 manuals say custom screen-off gestures do not work while the phone is locked (only the built-in O, V and music gestures do), so expect to unlock with fingerprint, face or PIN before our entry opens. The ColorOS 14.0, 14.1 and 15.0 manuals do not cover screen-off gestures and the ColorOS 16 manual does not repeat the limit, so it is unconfirmed for ColorOS 14-16; test on the device. Draw O (camera), Draw V (torch) and the music gestures are fixed on/off toggles in OPPO's manual. Confidence is 'reported': OPPO's manuals document customisable gesture actions and give app examples (ColorOS 11: 'slide up to open the calculator'; ColorOS 16: Calculator, Recorder) but never say any installed app can be chosen; that option is shown in OPPO Community posts and press coverage of the shared ColorOS/OxygenOS 16 menu. Not counted: Quick Launch (fingerprint shortcut menu limited to supported apps) and the Find X9 series Snap Key / Quick Button (fixed actions only).
