Samsung SPH-L520ZKPSPR - Manual (Page 23)

Flick
Flicking the screen is similar to swiping, except that you need to swipe your finger in light, quick
strokes. This finger gesture is always in a vertical direction, such as when flicking the contacts
or message list.
Pinch and Spread
“Pinch” the screen using your thumb and forefinger to zoom out or “spread” the screen to zoom
in when viewing a picture or a Web page. (Move fingers inward to zoom out and outward to
zoom in.)
