Please replace the original abstract paragraph with the following new paragraph. A mobile terminal includes a housing and a camera. The camera is rotatably coupled to the housing and configured for locking at a specified position. When the camera is locked at a first specified position, the camera is located inside the housing and one side of the camera is exposed outside the housing, and when the camera is locked at a second specified position, a lens of the camera is exposed outside the housing. The mobile terminal further includes a drive apparatus and a touch apparatus. The drive apparatus is configured to drive the camera to rotate, and the touch apparatus includes a touch sensor and a control chip. After receiving a touch signal from the touch sensor, the control chip controls the drive apparatus to drive the camera to rotate to the second specified position.
