The visual displayed when no app or widget is actively in use on an iPhone or iPad screen is a customizable element. This element commonly consists of a static image, a dynamic wallpaper, or a solid color. It serves primarily as an aesthetic backdrop to the icons and widgets arranged on the home screen and lock screen.
The selection and personalization of this display element allows users to express individuality and enhance device usability. Historically, operating system updates have included new default options and expanded customization features. These improvements often aim to improve the user experience, accessibility, and device aesthetics.
