Abstract: A terminal management method and an apparatus, where the method includes that a terminal obtains a first light intensity at a first moment and a second light intensity at a second moment according to a first interval period. The second moment is later than the first moment. When a difference between the first light intensity and the second light intensity is greater than a first threshold, and the second light intensity is less than a second threshold, the terminal closes a target program.

Abstract: A terminal and a method for detecting luminance of ambient light, where the terminal includes a processor, an ambient light sensor, and a screen. The ambient light sensor and the screen are both coupled to the processor. A light-sensitive element of the ambient light sensor faces the screen and is located on a lower surface of the screen. After the screen is lit up, the processor adjusts first luminance of the screen to a value below a first threshold within a visual persistence time of human eyes. The ambient light sensor detects luminance of first ambient light of the terminal within the visual persistence time of human eyes. The terminal may eliminate non-ambient light that enters the ambient light sensor such that the ambient light sensor may detect luminance of relatively real ambient light.
