Systems, methods, and computer-readable media for presenting visual content with a consistent orientation

摘要

Systems, methods, and computer-readable media are provided for presenting visual content with a consistent orientation on a display of an electronic device, even when the device is powered down and powered up again. Last known orientation information used by an application program to present application content with a particular orientation can be stored in a preference file that may not be accessible to a boot loader used during a boot process. To ensure that the boot loader may present boot up content with the same particular orientation indicated by the orientation information stored in the preference file, a register accessible to the boot loader can be used to store the same orientation information.
