How can I restore missing wallpapers on iPhone 15 Pro with iOS 18.3?

Wallpaper options on an iPhone often evolve with major iOS updates as Apple introduces new designs to reflect the aesthetic and features of the latest software. These wallpapers can include dynamic, still, or live options that highlight new themes, color schemes, or technologies.

Apple may choose to discontinue old wallpapers for various reasons, such as maintaining a modern look, aligning with updated branding, or encouraging users to adopt newer designs. Conversely, they may occasionally retain or reintroduce classic wallpapers for nostalgic value or by popular demand.

Users who prefer older wallpapers can sometimes find them through third-party apps or websites, although these may not offer the same quality or resolution as native options. For many, wallpapers are a personal expression, and their availability significantly enhances the customization experience.

Hello~ No…it’s not a “bug” at all. As has been explained Apple changes stock wallpapers often. If you find one you like then download it to photos. It’s the same with ringtones…they change as well. Progress forward is something we can’t stop…

Apple will occasionally update their wallpapers. Though you can search on the web for the iPhone 15 Pro wallpaper, then save it and upload it as your wallpaper, which is a workaround.

No idea what “branded wallpaper” you’re referring to.
