One great feature of the new Samsung devices is the inclusion of a native theme store and theme engine. In the past you would need to root your device and install a custom rom in order to use a custom theme.
Samsung has done a pretty great job of keeping their theme selections fresh. They have been adding themes on a weekly basis. This week we get a major theme dump with Samsung releasing 124 new themes! Some of the best looking new themes include Neon Wine, Simple Metal Compas, Silent Night, Flat Touchwiz, and Pulse UI. Head to Samsung's Theme store on your Samsung device to browse all the new themes.
