Zusammenfassung:	An ambient light detection method and an electronic device are provided to prevent leaked screen light and/or screen transmittance from affecting ambient light detection. The method is applied to an electronic device. A first ambient light detection unit and a second ambient light detection unit are disposed in the electronic device. A first photosensitive area of the first ambient light detection unit is used to detect intensity of first light, and a second photosensitive area of the second ambient light detection unit is used to detect intensity of second light. The first light includes ambient light and leaked screen light, and the second light includes the leaked screen light. A calibration coefficient is further configured in the electronic device. The method includes: the electronic device determines intensity of the ambient light based on a first value, a second value, and the calibration coefficient.
