Drag
To drag, press and hold your finger with some pressure before you start to drag. While
dragging, do not release your finger until you have reached the target position.
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.
