You will also find the following on the back of your device:

Back Camera
The back camera is on the top back of the case.
The Toolbox contains a menu for this rear-facing camera. Your MAP may also have a Camera Page or a Camera Activity that contains the CAMERA MENU.
The rear-facing camera is a fairly simple one and can be used to take pictures of things you might like to use for personalized icons or visual scenes.
The camera will zoom in and allow you to pan in any direction.
You can hold a real photograph 6-8 inches away from the lens and take a picture of the photo.
Note: You cannot download pictures to a computer and print them out as you can with a full-blown digital camera.
Table Stand
You can change the table stand to a lower angle.
