In one illustrative embodiment, a functional device hardware element of a mobile telecommunication device is provided externally by forming a dual geometric structure in an exterior surface of at least two device side edges of a device housing. The device housing has first and second grooves being substantially disposed from the front surface to the back surface across the side circumferential surface of first and second device edges of at least four device side edges, respectively, such that a combination of the first and second grooves is configured to jointly define at least one of a shape and a size of a predefined geometric structure that is selected to externally form a functional device hardware element of the mobile telecommunication device from the device housing of the device body. |
