Abstract
An ambient light sensor may be used to measure ambient light in an environment that surrounds a device. The measured ambient light may be used to adjust display settings employed by the device, and thereby improve a user experience during interaction with the device in the environment. During use of the device that includes an ambient light sensor, the ambient light sensor may become obscured (blocked, covered, etc.) by a user's finger, a cover, dirt, and/or by another object that obstructs the ambient light sensor's ability to detect light from the environment. Various techniques may be used to determine obstruction of the ambient light sensor. In some embodiments, changes in display settings may be compared to measured changes in ambient light to determine whether a light sensor is obstructed. In some embodiments, use of a second light sensor may validate whether a first light sensor is obstructed.
