The customization of the visual backdrop displayed when a device is locked and inactive is a frequent user modification on mobile operating systems. This involves selecting a preferred image or design that appears on the screen before the device is unlocked. For example, a user might choose a personal photograph, a pre-installed graphic, or a downloaded image as their chosen display.
Modifying the default presentation enhances user experience by personalizing the device, making it more aesthetically pleasing, and potentially providing a sense of ownership. The ability to alter this image has been a feature of mobile operating systems for several years, evolving from static pre-loaded images to supporting user-supplied media, dynamic wallpapers, and even integration with third-party applications.
