The Nexus S works just fine with camera previews. See: https://github.com/commonsguy/cw-advandroid/tree/master/Camera/Preview https://github.com/commonsguy/cw-advandroid/tree/master/Camera/Picture
The first one is just preview, working with the default camera. The second one also takes pictures and will use the FFC on Android 2.3 and newer devices (if there is an FFC), otherwise it will use the default camera.
