Abstract
Apparatuses and methods to operate a display device of an electronic device. In some embodiments, a method includes receiving a user setting of a display control parameter, and altering, based on the user setting, an effect of an ambient light sensor value (ALS) on control of the display control parameter. Also, according to embodiments of the inventions, a method of operating a display of an electronic device includes receiving a change to one of a display brightness output level and an ambient light sensor output level, and altering, according to the change, a display contrast output level. In some embodiments, a method of operating a proximity sensor of an electronic device includes receiving a light sensor output, and altering, according to the output, an on/off setting of a proximity sensor. Other apparatuses and methods and data processing systems and machine readable media are also described.
