A mobile terminal includes a housing, a first
user interface located on a first face of the housing, a second
user interface located on a second face of the housing different from the first face, and a controller within the housing and coupled to the first and second user interfaces. The second
user interface includes a touch sensor configured to be used in tandem with the first user interface. The second user interface is positioned on the housing relative to the first user interface such that, when the mobile terminal is held in the user's hand, the first user interface is operable by a
thumb and the second user interface is operable by a finger of the same hand. The first user interface is configured to receive a first
user input, and the second user interface is configured to receive a second
user input. The controller is configured to detect a combination of the received first and second user inputs, and is configured to perform a mobile terminal function associated with the detected combination responsive to detection of the combination. Related user interfaces and methods of operation are also discussed.
