The Galaxy S6 and S6 edge were the first Android devices from Samsung to support third-party themes. Later, themes started supporting live wallpapers. Now, Samsung has added support for icon packs in themes with the Galaxy Note 7 along with a slightly revamped UI.
The themes section in the newly announced Galaxy Note 7 comes with three sections: wallpapers, themes, and icons. Users can now mix and match wallpapers, icons, and themes, which is a great addition to customizability since there were many beautiful themes in the Theme Store with poorly designed icons.
Support for icon packs was first revealed when Grace UX was leaked for the Galaxy Note 5. However, the Galaxy Note 7 is the first Samsung smartphone to support this feature out of the box. We don't know whether this feature will be rolled out to existing devices such as the Galaxy S7, Galaxy Note 5, or the Galaxy S6.
