摘要： An electronic device for preventing misrecognition by a proximity sensor is provided. The electronic device includes a display, a proximity sensor disposed under the display, at least one processor operatively connected with the display and the proximity sensor, and a memory operatively connected with the processor. The memory stores instructions that, when executed, cause the at least one processor to in response to the display being turned on, detect a light entering the proximity sensor by using the proximity sensor, calibrate a reference range, based on a characteristic of the entering light, and identify whether an external object is close to the electronic device, based on the calibrated reference range.
