Spy Phone

Spy Phone is your all in one camera application for secretly taking pictures, recording video (HD on 2.2) and audio. Use the menu to switch between output formats and display a small preview. You can disguise your camera with a blank screen, custom wallpaper or web browser.

Custom wallpaper works best when resized to match your screen resolution.
