Using the keyboard
Use the keyboard to enter text and other
symbols in many applications on your
smartphone, as well as to dial phone
numbers (see Making calls
).
Understanding the keyboard backlight
Your smartphone includes a keyboard
backlight for low light conditions. The
keyboard backlight activates automatically
when the screen turns on. The backlight
turns off automatically when the screen
turns off or when you are on a call or
playing music in the background for longer
than the time specified in Backlight
Settings. You can set different time
intervals depending on whether the
smartphone is operating on battery power
or is connected to an external power
source. The backlight also turns off when
an application’s power-saving features turn
it off.
