vivo's FAQ describes Quick action (older name: Smart click) as holding Volume Down for a few seconds while the screen is off and no music is playing, and says it does not work while the proximity (IR) sensor is covered, so it should not fire inside a pocket or bag. The FAQ only shows the flashlight action. Reviews of Funtouch OS 13 phones (vivo V27 Pro, T2 Pro) report that the list also offers opening any app the user picks. vivo's own Quick action app (SmartKey) in Funtouch OS 12 Global (vivo V25 Pro, Y16, iQOO 9T), Funtouch OS 14 (iQOO 12) and Funtouch OS 15 (iQOO 13) firmware has the options 'Open app' and 'Select app' and the hint 'Quick action is unavailable during music playback or when the IR sensor is blocked'; confidence stays 'reported' because no vivo support page documents the open-app option. Funtouch OS 14 and later also offer double-pressing Volume Down for the camera only. One long press is one event; there is no double-press variant for apps (GSMArena V29 Pro review). Not documented for OriginOS 6 (global phones from late 2025, including Funtouch OS phones updated to it). vivo says apps opened by the related Smart wake gestures only open after unlocking when a lock-screen password is set; whether Quick action behaves the same is not documented.
