Taking a quick photo
Open the Camera app and point the lens toward the subject you want to photograph.
Touch the subject on the screen and a focus box will appear in the viewfinder. When the focus box turns green, the camera has focused on your subject.
Tap the Capture button
to take the picture.
You can zoom up to 4 times while taking a picture. Place two fingers on the screen and spread them apart to zoom in (a zoom bar indicates the zoom level) and pinch in to zoom back out.
The captured image retains the orientation in which it was taken. If you hold the phone both vertically and horizontally to take pictures, you’ll need to rotate the phone to view full screen images in the Gallery app.
While viewing a photo, you can tap the Menu Key 
, then tap Rotate right/left to manually
change its orientation.
