Samsung SM-N900PZKESPR - Manual (Page 34)

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.
Rotate
For most screens, you can automatically change the screen orientation from portrait to
landscape by turning the phone sideways. When entering text, you can turn the phone sideways
to bring up a bigger keyboard.
