Samsung Opens One UI 4 Beta Program for Galaxy S21 DevicesShare open/close
Participants can preview the new and enhanced user interface and submit feedback ahead of the official release
Samsung Electronics today announced the launch of its One UI 4 Beta Program for Samsung Galaxy S21 smartphones (Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra). One UI 4 is based on Android 12 operating system (OS) and introduces new and improved customization and privacy capabilities that give users control over many aspects of their mobile experience.
“One UI 4 helps users create their own, optimized mobile experience because Samsung recognizes that, everyone wants to meet their unique needs and preferences,” said Dr. TM Roh, President and Head of Samsung Electronics’ Mobile Communications Business. “As we’ve done with every iteration of our One UI, we’ve listened to our users to understand the tools and innovations needed to create a better, more reliable, and enhanced overall user experience.”
One UI 4 Beta Launch
The One UI 4 Beta Program allows users to try out One UI 4’s upgraded features ahead of its official release. Samsung Galaxy S21 series1 owners in select markets2 can register for the beta program via the Samsung Members app on their devices. Participants will be able to preview the One UI 4 design and new features3 and submit feedbacks. Samsung will use the information gathered from the beta program to fine-tune the One UI 4 user experience before delivering a final, optimized upgrade later this year.
Delightful Experiences, Designed by You
Samsung’s One UI user interface brings a unified mobile experience to Galaxy smartphones through simplified and streamlined interactions and a clean and elegant design.
One UI 4 beta participants will be able to experience comprehensive customization capabilities and privacy controls that empower them to design their ideal mobile experience — one that’s uniquely suited to their individual needs and allows them to express who they are.
The Look You Want
With One UI 4, users get customization options at every turn. A wealth of theme options let the users adjust the look and functionality of their device, giving them tools to configure their home screens, icons, notifications, wallpapers and much more. Plus, redesigned, upgraded widgets offer deep customization — from visibility to appearance. Users also get convenient access to a more robust and diverse array of emojis all in one place, so they can effortlessly navigate their options to enjoy richer communication experiences.
Empowering Privacy Options, Total Protection
The new One UI 4 also brings enhanced privacy and protection functions that make it easier for users to understand exactly how their data are being used to customize their settings and deliver a more personalized mobile experience. Indicators alert users to app camera and microphone usage, so they can instantly disable permissions if they don’t want to grant access. One UI 4 also expands on Android 12’s permission options, allowing users to view their permissions history from the last seven days, not just the last 24 hours. They can also check the current data usage of both their permissions and their apps.
1 The users of Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra can participate in the beta program.
2 The Beta Program will be available in China, India, Germany, Poland, South Korea, UK, and US. The release date can vary by each market.
3 Some of the new features might not be supported when beta program is open.
