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 focus. The One UI home screen with colorful icons. The One UI phone keypad, photo gallery, calculator, and calendar applications onscreen. Samsung Notes, Night Mode, email inbox, and search function applications onscreen.

Focus on the
task at hand

Find and focus on the content you want easily.

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

And with clear and intuitive visuals, you don't have to give it a second thought.
