G8 ThinQ

Requires: LG G8 ThinQ (LM-G820): its Z Camera (ToF sensor and IR illuminator next to the front camera) recognizes the hand

LG's G8 ThinQ user guide: while the Home screen or an app is shown, a swipe left or right in the air opens the app chosen under Swipe left or Swipe right, and a pinch with all fingers takes a screenshot instead. One oem_key event means one complete palm, cup and swipe sequence, and it needs the screen on. LG notes that Air Motion may not work in some apps, that the ToF sensor and IR illuminator must not be covered, that the hand must not move too fast or too far away, and that gloves or direct sunlight lower recognition. Some carrier versions of the manual put the menu under Settings > General > Air Motion. The Shortcuts keys on this phone are fixed: a double press of the power key or Volume Down opens only the camera, a double press of Volume Up opens only Capture+, and the Google Assistant key opens only Google Assistant or Google Lens.

Requires: LG UX with the Floating Bar (Settings > Extensions > Floating Bar); only the models that list this capability

The Floating Bar is an on-screen tab, not a hardware key: one tap opens it and a tap on our shortcut opens the entry, so one oem_key event means two taps, and it works only while the screen is on and unlocked. LG's G8 ThinQ and V50 ThinQ user guides list Shortcuts as one of the Floating Bar's sections (with Screen capture, Music player and Quick contacts); AT&T's LG tutorials and LG's V30 manual say that apps or features can be added to Shortcuts, up to five. The bar can be dragged along the screen edge or dragged to the top to hide it. The V60 ThinQ user guide (Verizon) has no Floating Bar, so later models are not listed.
