One UI 3 is designed to help you focus on what matters. Our visual redesign has improved the places you visit the most to reduce distractions, highlight important information, and make your experience more consistent. Performance improvements will help apps run quicker while using less battery power. And One UI 3 puts control in your hands with new privacy controls, one-time permissions, and enhanced Digital Wellbeing.

Refreshed visual design

We’ve redesigned the look and feel of One UI 3, especially the places you visit the most, like the Home screen and quick panel. Motion is smoother and more natural with improved animations and haptic feedback for common interactions. And the interface responds to different screen sizes to provide the best experience on any device, whether it’s a phone, foldable, or tablet.

Improved performance

We optimized One UI 3 with enhanced dynamic memory allocation, so apps run faster and perform better. We’ve also restricted background activities to provide better performance and power usage.

As Apps are more customizable and personalized, a handful of features of One UI foundation is necessary to create more joy in your life. You can add a widget to check your usage time on the Lock screen or a call background when making or receiving a call. Bixby Routines has even more controls to help you automate your life. 

Enhanced features

Everyday experiences like making calls, sending text messages, taking pictures, and navigating through settings have been improved in many ways, big and small.
