One UI is effectively a complete redo of Samsung's interface, colors and iconography from top to bottom. Far more than a coat of paint. The software is even further flattened, and puts emphasis on whites and greys with liberal use of soft-radius corners and negative space. In many ways One UI follows Google's Material Design principles — take a look at a Pixel 3 alongside a Note 9 and there are striking similarities in the notification shade, settings, multitasking screen and menus. Visually, this is the best software Samsung has ever made. The consistency of design implementation across the interface and apps is near-perfect, and it feels light and modern both at a glance and with use.
