Change Home Screen Wallpaper auf Oppo
On Oppo phones running Coloros, holding down on the home screen opens a shortcut menu with only a few built-in wallpaper presets. This shortcut skips the full wallpaper library, which is why photos, animated wallpapers and additional themes seem to be missing.
The complete set of options lives in the system settings instead. Open Settings ➔ Personalizations ➔ Wallpapers to reach every category, including static presets, live wallpapers and your own gallery photos.
To use a personal photo, tap Photos and select the image you want. Coloros then shows a crop and preview screen where you can adjust framing before confirming.
Tap Apply once you are happy with the preview. On the next screen choose Home screen if you only want to update the home screen and keep a different wallpaper on the lock screen.
Use the quick home screen shortcut only when you want to switch between wallpapers you already applied before. For anything new, including live wallpapers or gallery photos, the Wallpapers settings page is the reliable path.
