Flick
Slide with two fingers
Flicking the screen is similar to swiping, except that
you need to swipe your finger in light, quicker
strokes, such as when moving right and left on the
Home screen, or flicking through a contacts or
message list.
In some apps, like Gallery or the web
browser, slide two fingers apart to zoom
in when viewing a picture or text.
Slide two fingers together to zoom out of the picture or
text.
