Chapter 2 : Basics 19
Why the screen goes dark
If you hold the phone up to your ear while on a call, the screen goes dark.
This is normal behavior. It prevents your accidentally tapping an item on the
screen and saves battery power. When you take the phone away from your
ear, the screen automatically turns back on, ready for use. If the screen
doesn’t turn on fast enough for you, tap the screen to wake it up.
The same behavior occurs anytime you’re on a call and the phone screen is
placed near another surface. The screen turns on automatically (if the phone
is still on) when you move the phone away from the other surface.
When the phone is on and idle, the screen first dims and then turns off. This
also is normal behavior, caused by the auto shut-off interval. You can adjust
this auto shut-off interval to be as long as three minutes (see
Set the interval
for turning the screen off automatically ). At first, the screen dims as a
power-saving measure. Just tap the screen to brighten it. Then, if your
phone remains inactive for the full interval you set, the screen turns itself off.

Turn the screen on/off

NOTE Pressing power to turn the screen off also works when your phone is
placed on a Touchstone charging dock (sold separately).

plane or anywhere else you need to turn off all wireless services. You can’t
browse the web, but you can still use apps like Calendar, Contacts, Photos,
Music, Quickoffice

mobile office software, and PDF View.
