landscape by turning the phone sideways. When entering text, you can turn the phone sideways
to bring up a bigger keyboard.
Pinch and Spread
“Pinch” the screen using your thumb and forefinger to zoom out or “spread” the screen to zoom
in when viewing a picture or a Web page. (Move fingers inward to zoom out and outward to
zoom in.)
