As per the X user @the_husbandalorian on Threads, Android 15 beta version 3, Google is developing a new option to share AI-generated wallpapers. This new feature is located in the wallpaper picker interface, where users can now find a share button on the preview screen.
Android 15 will support sharing AI wallpapers
This interface lets users see how their wallpaper would look on their home and lock screens, and includes a share button alongside a pencil icon.

Currently, the sharing feature isn’t working. When you try to upload the wallpaper to apps like Google Drive, you get an error. However, this seems to be a work in progress, so it might be available in a future Android 15 beta or stable release. Once it’s enabled, Pixel users will be able to share their creative wallpapers with friends and family, or even inspire others to create their own unique designs.
