1. A method for estimating a screen light leakage amount, applying to a second electronic device, wherein the second electronic device comprises a processor, a display screen and an ambient light sensor, and the ambient light sensor is arranged under the display screen, the method comprising:
acquiring, by the processor, a first screen light leakage estimation model of a first electronic device;
acquiring, by the processor, a first detection value of a variable of the screen light leakage estimation model of the first electronic device under a preset configuration;
acquiring, by the processor, a second detection value for the variable of the second electronic device under the preset configuration;
determining, by the processor, a difference coefficient of the second electronic device relative to the first electronic device according to the first detection value and the second detection value; and
determining, by the processor, a second screen light leakage estimation model of the second electronic device according to the first screen light leakage estimation model and the difference coefficient, and the second screen light leakage estimation model being configured to estimate the screen light leakage amount of the second electronic device;
detecting, by the ambient light sensor, an ambient light;
subtracting, by the processor, the screen light leakage amount from the ambient light, to obtain relatively accurate ambient light.
