Samsung Themes Installation Instructions Keep in mind I am not an approved Samsung Themer but there is a way to apply these themes. You will need a "Package Disabler" app from the playstore. I use BK Package Disabler. It cost $1.99 but my themes are free.

** I do have several icon packs on this website that match these themes with almost 3000 icons in each set so be sure to look for something that matches**
There are two other people that I'm aware of who also do these type of themes. They do more of the "cute" themes like Hello Kitty which everyone seems to love so please check them out. My themes are more to color coordinate throughout your phones and these ladies design the whole phone by theme type.
(Ladypinkilicious also has a tutorial on how to apply these themes and a package disabler apk on her site)
