Abstract
An electronic reading device can include an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device can include circuitry configured to receive a signal from the ambient light sensor corresponding to a detected ambient light level, automatically display a default brightness level based on the detected ambient light level, determine if the brightness level is manually adjusted, automatically adjust the relative brightness based on the manually adjusted brightness level when the ambient light level changes, and update preferred relative settings to correspond to the manual adjustment.
