Abstract
A method includes illuminating at least a portion of a display proximate an ambient light sensor of a device, detecting a first light measurement using the ambient light sensor responsive to the illuminating, and generating an asserted value for a proximity state of the device based on the light measurement exceeding a first predetermined threshold. A device includes a display, an ambient light sensor, and a processor coupled to the display and the ambient light sensor to illuminate at least a portion of the display proximate the ambient light sensor, detect a first light measurement using the ambient light sensor with the display illuminated, and generate an asserted value for a proximity state of the device based on the light measurement exceeding a first predetermined threshold.
