15 The Basics
Pinch-to-zoom
Use your index finger and thumb in a pinching motion (to zoom out) or
spreading motion (to zoom in) when using Chrome, a map, photos, the rear
camera lens, the Contacts list, the Favorites list, the Groups list, a music
list, and Polaris Office 5 documents. Spread apart to make screen
information larger (easier to see and read), or pinch together to view more
area and information. The pinch gesture also changes the Home screen.
Pinch in on the Home screen to change to mini canvas view, then spread
apart to return to the normal Home screen view. Spread apart on the
normal Home screen to hide all of your Home screen items, then pinch in
to redisplay them.
Rotate the screen
From many apps and menus, the orientation of the screen adjusts to the
device’s physical orientation. You can deactivate this function in the Display
settings menu.
