Touch
To act on items on the screen, such as application and settings icons, to type letters and
symbols using the onscreen keyboard, or to press onscreen buttons, you simply touch them
with your finger.
Touch & hold
Touch & hold an item on the screen by touching it and not lifting your finger until an action
occurs. For example, to open a menu for customizing the Home screen, you touch an empty
area on the Home screen until the menu opens.
Drag
Touch & hold an item for a moment and then, without lifting your finger, move your finger on
the screen until you reach the target position.
Swipe or slide
To swipe or slide, you quickly move your finger across the surface of the screen, without
pausing when you first touch it (so you don’t drag an item instead). For example, you slide
the screen up or down to scroll a list.
Lock screen
When Screen lock in Security setting is enabled, press Power key to lock the handset. This helps
to prevent accidental touching of keys and as well as power saving. When Sleep function
in Display setting is enabled, after the handset device has been idle for preset period, the
screen will be locked automatically to save power.
