A mobile communication device having a first side and an opposite second side, comprising a lower housing, an upper housing, a bracket, a biasing assembly and a slide enabling member. The upper housing stacked on the lower housing, the upper housing comprising a first edge located at the first side and a second edge located at the second side. The bracket is pivotably connected between the lower housing and the upper housing, to tilt the first edge of the upper housing away from the lower housing. The biasing assembly is connected directly between the lower housing and the upper housing, to exert a force between the lower housing and the upper housing so that the bracket rotates to tilt the first edge of the upper housing away from the lower housing. The slide enabling member slidably coupling the biasing assembly to the lower housing.
