Abstract
A method for detecting the state of the proximity sensor, applied to a terminal including the proximity sensor and an antenna, includes: sending a predetermined instruction to the proximity sensor; determining whether the proximity sensor is abnormal based on a feedback result of the proximity sensor to the predetermined instruction; and maintaining the antenna transmitting power at a low power if the proximity sensor is abnormal. Through the feedback of the proximity sensor to the request to obtain the capacitance value, it is determined whether the proximity sensor can work normally, and in a case that the proximity sensor cannot work normally, the antenna transmitting power is reduced to avoid the continuous high antenna transmitting power due to the inability of the proximity sensor to work normally, which reduces the radiation to the human body.
