Abstract
An electronic device includes a reflective proximity sensor for emitting light and detecting whether a wavelength of a reflective light is the same as a wavelength of the light emitted by the reflective proximity sensor, an optical sensor for sensing variation of environmental light, and a controller coupled to the reflective proximity sensor and the optical sensor for controlling operations of the electronic device according to a detection result of the reflective proximity sensor and a detection result of the optical sensor. Hence the electronic device can determine whether it is being placed into a handbag or a pocket.
