Applying Theme to phone

Hi, is there information on how to apply themes to one’s galaxy phone independent of whether they are approved for Galaxy store. I mainly want to create my own theme… beyond wallpaper and lock screen, even beyond Theme Park interface on icons and thematic colors. Like a full fledged theme, I want to be able to create my own icons, AOD, keypad screen, etc… and apply it to my phone.

Are there easy ways to do this, applications that support this, more complex work-arounds? I appreciate any help with this. Thanks!

You can not create or apply Themes to Samsung devices. Themes require access to core functionality that is not available to the public. You must apply for and be approved as a Galaxy Theme Designer.

You can use Android tools to create wallpapers for your personal use.
