Abstract: A dynamically attachable and detachable electronic viewfinder device provides a duplicate electronic display for attachment to any camera-enabled device. This viewfinder device may be attached to the non-display (rear facing) side of the camera-enabled device without obstructing the view of any native factory-installed cameras, while providing a secondary user interface display that shows live imaging from the rear side cameras and provides auxiliary touch screen capability.
