Samsung has announced the launch of its new Android overlay, the One UI 4, for its Galaxy S21 series of phones. This includes the Samsung Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra.
The biggest change in the new user interface is the ability to further customize your phone. This includes new Color Palettes, which change the look and feel of most elements on your phone such as home screen, icons, notifications and wallpapers. Widgets now offer more customization, and Samsung has also increased the number of emojis, GIFs, and stickers on offer.
