Determination of a closed or open status of a mobile communication device, having a cover that may be in hinged or in slidable engagement with the device body housing, is made by sensing an input from the device microphone. The cover and housing form an acoustical seal when the device is closed. In accordance with the sensed input of the microphone the device controller can detect whether the cover is in a closed or open state with respect to the housing. An off-hook telephone status can then be set when the open state is detected on the basis of the microphone input and the telephone display activated. |
