Flick
Pinch and spread
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, spread your fingers on the
screen to zoom in when viewing a picture
or a webpage.
