A portable communication apparatus adapted to be extendedly rotated in multiple stages and a method thereof. The apparatus and method comprise a first housing extending along a longitudinal direction; a second housing connected to the first housing by a dual hinge device and adapted to be rotated in multi-stages toward or away from the first housing about first and second hinge axes in a direction perpendicular to the longitudinal direction; a dual hinge device which rotatably connects the first and second housing to each other, provides the first and second hinge axes, and is adapted to rotate the second housing about the first hinge axis, as well as to rotate the second housing about the second hinge axis in such a manner that the second housing extends along the longitudinal direction of the second housing when a button unit, which is exposed to the exterior of the first housing, is pressed; and a hinge locking module positioned in the first housing and the dual hinge device to extendedly rotate or hold the second housing as the button unit is pressed.
