Abstract: A terminal device having a rotatable image capture component, including a magnetic body and a sensor. A change in the magnetic flux caused by rotation of the magnetic body is identified by the sensor, and used to identify whether the image capture component is in a front-facing state or a rear-facing state. The magnetic body is mounted in a connector of the image capture component or at an end of the connector. The sensor is mounted on a circuit board using a bottom surface perpendicular to a Z-axis of the sensor. When the image capture component is at a front-facing position and a rear-facing position, an angle between a connection line, which connects a south pole and a north pole of the magnetic body, and a radial line of an image capture unit included in the image capture component is less than a preset value in a rotation direction.

Abstract: In a control method relating to the field of electronic device control technologies, and in particular, to a technology for controlling terminal state switching, when receiving a state switching instruction in a lock screen state, a terminal obtains motion data within a predetermined lime period of the terminal and an intelligent wearable device bound to the terminal. When a deviation between two groups of motion data is less than a deviation threshold, the terminal performs state switching. The terminal state switching is implemented through cooperation of the intelligent wearable device, and therefore a possibility of leakage of information in the terminal can be reduced.
