Abstract: The present invention discloses a handheld electronic device, including a cover, a fingerprint sensor, and a light emitting unit. The fingerprint sensor and the light emitting unit are disposed inside the handheld electronic device. The cover includes a light transmitting area. The light emitting unit is disposed opposite to the cover and is adjacent to the fingerprint sensor, so that the light emitting unit can emit light through the light transmitting area, so as to indicate a location of an ultrasonic fingerprint sensor. The handheld electronic device disclosed in the present invention has better water-proof performance and dirt-repellent performance.

Abstract: The present invention provides a terminal control method, a protective case, and a terminal. In the method, a terminal may be disposed with two Hall effect sensors for sensing a change of a magnetic field generated by a magnet in a protective case, and identify a forward snap-fit operation, an opening operation, a backward snap-fit operation, and the like of the protective case. When detecting the forward snap-fit operation of the protective case, the terminal performs a screen off operation; or when detecting the backward snap-fit operation of the protective case, the terminal may skip performing screen off operation. In embodiments of the present invention, the protective case can be prevented from turning off a screen by mistake, so as to improve terminal control accuracy.
