One UI 3.1 Upgrade (Android 11)

One UI 3.1 is designed to help you focus on what matters. Our visual redesign has improved the places you visit the most, like the Home screen and quick panel, 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 3.1 puts control in your hands with new privacy controls, one-time permissions, and enhanced Digital Wellbeing.

Visual design

We’ve refreshed the look and feel of One UI 3.1 in lots of ways, big and small, from new, more consistent icons to smarter organization of the quick panel and notifications. Motion is smoother and more natural than ever, 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 3.1 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.

Accessibility for everyone

One UI 3.1 recommends useful accessibility features for you based on your usage. The improved Accessibility shortcut makes accessibility features easier to start and use. You can use the Speak keyboard input aloud feature to get voice feedback of your typing even when TalkBack is turned off.

Stronger privacy protection

You can now let an app access to your microphone, camera, or location just one time. Any permissions that an app hasn’t used in a while will be automatically revoked.
