The dynamic background feature on Apple’s mobile operating system allows users to personalize their device’s home and lock screens with animated images. These moving visuals respond to touch or device movement, adding an interactive element beyond a static picture. For example, a user might select a pre-designed animation or create one from a Live Photo, resulting in a subtly shifting background.
This capability enhances the user experience by providing a customizable and visually engaging interface. It represents a progression in mobile device personalization, moving beyond simple picture displays to offer a more interactive and expressive medium. Historically, it built upon earlier customization options, gradually increasing the level of user control and visual dynamism.
