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.
