A mobile terminal includes a display, a back cover, a middle frame, a rotation system, and a drive mechanism. A notch is disposed on a top of the back cover, and the rotation system is located at the notch. The rotation system includes a camera, and an outer surface of the rotation system and the back cover are spliced into an outer surface of the mobile terminal. The drive mechanism is configured to drive the rotation system to rise, fall, and rotate, such that the camera has functions of both a rear-facing camera and a front-facing camera.
