Abstract:
An operation method and an electronic device are provided. A proximity detection mode is activated in response to deactivating the display during an execution of a call application. In response to activating the proximity detection mode, a proximity distance of an object is identified based on outputting the light through the light emitting unit and receiving the light through the light receiving unit. If the identified proximity distance is larger than a pre-defined proximity recognition distance, the proximity detection mode is deactivated and the display is activated.
