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.

Abstract: A method for controlling screen rotation of an electronic reading device that includes processing circuitry, an accelerometer, and a display screen. The method including: receiving, by the processing circuitry, a request to access a menu for initiation of a screen-rotation lock function for the electronic reading device; displaying, on the display screen, the menu for the initiation of the screen-rotation lock function; receiving, by the processing circuitry, a selection of one particular screen orientation for the display screen from among a plurality of screen orientations; rotating, the electronic reading device, 90 degrees; detecting, by the accelerometer, the 90 degree rotation; and maintaining a screen that is displayed on the display screen in the selected one particular screen orientation.

Abstract: A method for annotating dynamic content includes receiving a freeform annotation overlaid on dynamic content; determining whether the dynamic content changes; in response to a determination that the dynamic content changes, displaying an indicator corresponding to a region where the freeform annotation was created; determining whether the indicator is selected; in response to a determination that the indicator is selected, displaying a lightbox with the freeform annotation as it was overlaid on the dynamic content when it was created; determining whether the a revert button included in the lightbox is selected; and in response to a determination that the revert button is selected, displaying the freeform annotation overlaid on the dynamic content as it was created before the dynamic content changed.
