HI @Flintstone The palm to swipe feature is available on many Samsung Devices. it s accessible via Settings-Advanced Features- Motions and Gestures-Palm Swipe to Capture (ensure that is toggled on) Other options are to use Voice Assistants (Bixby or Google Voice) or to to set it up in Tasks via the Edge Panel.
