CyanogenMod supports system-wide themes, and these themes won’t just change your wallpaper and sounds — they’ll change the look of the entire operating system, allowing you to replace Holo with something more new.
Vivo creates an absolutely gorgeous flat UI with lots of built-in wallpapers, icons, sounds and plenty of themed apps. Everything in the system is themed from the keyboard to the status bar, toast notifications and boot animations.
