30 The Basics
Rotate the screen From many apps, the orientation of the screen adjusts
to the phone’s physical orientation by rotating the screen. You can
deactivate this function in the Display settings menu.
NOTE The Home screen doesn't rotate to landscape view.
Rotate the phone sideways for
landscape orientation. Rotate the phone upright for portrait
orientation.
Capturing the screen Press and hold the Volume Down Key and the
Power/Lock Key (on the back of the phone) at the same time to capture
the current image on the screen. The captured image is saved in the
Screenshots folder of the Gallery.
NOTE You cannot capture an image from some videos and apps.
The Smart screen feature
The Smart screen feature keeps the phone from activating screen time-out
when it detects your eyes looking at the screen. When you turn this feature
on, you can set a shorter screen time-out to conserve your battery power,
but still allow you to view a screen for a longer period of time without
having to touch it to keep it activated.
To turn this feature on, from the Home screen, touch and hold the Recent
Apps Key
(in the Touch Keys bar) > Settings > Display > checkmark
the Smart screen checkbox.
NOTES The following situations may prevent this feature from functioning properly.
•
When the phone is in the dark or against bright light.
    •
When the camera lens can’t detect the location of your eyes.
•
When the front camera is used at the same time with other apps.
