Described are an electronic device, a camera, and a method for determining an orientation of a camera in an electronic device. The method includes measuring a position of the lens at rest within the lens cavity (680), determining a pointing direction of the camera based on the position of the lens (684), and moving the lens to a new or adjusted starting position for an auto-focus function based on the pointing direction (688). The lens is biased to a predetermined position within the lens cavity when the camera is oriented in a predetermined pointing direction. A lens position sensor can measure a position of the lens to record a measured position. By evaluating the measured lens position, the camera orientation can be determined. The auto-focus of the camera can be started at a starting position based on the camera orientation.
