Drag
Flick
Press and flick
Press and hold your finger with some pressure before you start to drag.
While dragging, don't release your finger until you have reached the
target position.
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.
On the Home screen, you can easily move a widget or icon from
one screen to another.
Press and hold the widget or icon with one finger, and flick the
screen to the new location with another finger.
