Abstract
A folding screen device includes a first body, a second body, a central processing unit (CPU), a first acceleration gyro sensor, a second acceleration gyro sensor, a first geomagnetic module and a second geomagnetic module. The first acceleration gyro sensor and the second acceleration gyro sensor are configured to obtain a body status of the folding screen device. The CPU is configured to control working statuses of the first geomagnetic module and the second geomagnetic module according to the body status.
