Galaxy wallpaper

I want to learn how we can upload any wallpaper on samsung themes from our creations?

Hello,
Welcome to Samsung Developer Community.

Galaxy Themes Studio is a GUI Design Authoring Tool exclusively for Galaxy smartphones provided to those selected as theme designers. Using this, you can create theme packages, wallpapers, icons, and AODs.

Content produced through Galaxy Themes Studio can only be distributed through Galaxy Store.

To be selected as a theme designer, you need to submit a portfolio consisting of theme design drafts for screening. The portfolio is accepted only during the theme designer recruitment period.
The final selected designer will be given the right to use Galaxy Themes Studio.

To learn more about Galaxy Theme Studio, please go through this guide.

Thank you,
Jakia
