Made to focus

One UI helps you focus on what really matters to you. With hardware and software working together in harmony, see only what you need,
using and viewing your phone with an experience that feels second nature. Because it’s the small details that make a big difference.

Multiple phones show how One UI screens change the Galaxy interface to make it easier for users to find what they're looking for. The One UI home screen with colourful icons. The One UI phone keypad, photo gallery, calculator, and calendar applications shown on screen. Samsung Notes, Night Mode, email inbox, and search function applications shown on screen.

Focus on the
task at hand

Find and focus on the content you want easily.
The decluttered screen shows relevant information with each tap, so you only get the essentials, one at a time.

Simulated One UI applications show how distinct pops of colour help users to quickly and easily find relevant information. The reminder application highlighted by a teal squircle. The alarm application highlighted by a purple squircle.


Reach what you want.
Content and features at your fingertips,
so you can get to them faster.
Interacting with your phone just feels natural.

Be visibly comfortable

One UI changes how you view your phone. Use Night Mode for a comfortable experience in the dark.
And with clear and intuitive visuals, you don't have to give it a second thought.
