Abstract

Methods and electronic devices for adjusting sensitivity of a proximity sensor are described. In an example aspect, the present application describes a method implemented by a processor of an electronic device for adjusting sensitivity of a proximity sensor associated with the electronic device. The proximity sensor is positioned biased towards a longitudinal side of the electronic device. The electronic device also includes an orientation sensor that generates orientation data based on an orientation of the electronic device. The method includes: obtaining orientation data from the orientation sensor; and increasing the sensitivity of the proximity sensor when the orientation of the electronic device is at a first tilted orientation based on the orientation data.
