The official launch of One UI 4 will roll out in Canada starting with the Samsung Galaxy S21 series 5G, including Galaxy S21 5G, Galaxy S21+ 5G and Galaxy S21 Ultra 5G, on December 6th, 2021. With new customization options, privacy features, support for eSIM[1], and access to the ever-expanding Samsung ecosystem, One UI 4 delivers an elevated mobile experience that puts you in control.


“We are committed to giving everyone access to the best mobile experiences possible, as soon as possible,” said Janghyun Yoon, Executive Vice President and Head of Software Platform Team at Mobile Communications Business, Samsung Electronics. “One UI 4 delivers on that promise, equipping Galaxy smartphone users with the latest customization and privacy features. But we won’t stop there. Soon, other smartphone and tablet users will also be able to benefit from this software update, enabling a more seamless experience across our entire ecosystem.”


Your Galaxy, Your Way

One UI 4 enables you to create a customized mobile experience to meet your unique needs and express your individuality. With a host of new colour palettes to choose from, you can alter the look and feel of everything from your home screen to icons, menus, buttons and background. And with reimagined widgets that offer enhanced customization, it’s now easy to put your own personal stamp on your smartphone experience. Self-expression opportunities have also been enhanced with a wider variety of emoji features, GIFs and stickers available directly from your keyboard.


Protect What Matters Most

With One UI 4, Samsung is delivering the latest privacy and security features so you can choose exactly what you want to share or keep private. From alerting you to when an app is attempting to access your camera or microphone, to a new privacy dashboard that brings all your settings and controls into one convenient place, with One UI 4, monitoring and controlling your privacy settings has been made easy and convenient.



Connecting You to an Extended Ecosystem

One UI 4 helps you to get the most out of the incredible extended ecosystem of Samsung devices and third-party apps, unlocking a more powerful mobile experience.


Partnerships between Samsung and other industry-leaders, like Google, ensure seamless experiences when using your favourite third-party apps and services. This means, you can enjoy apps like Google Duo, which provides high-quality video call opportunities for connecting with friends and family.



And whether you’re using a Galaxy Z Series smartphone, Galaxy Watch or Galaxy Tab, you’ll achieve a uniformed look and feel across all your devices with the ability to seamlessly sync them.




One UI 4 will be available on the Galaxy S21 series 5G starting December 6, 2021 and will soon become available on previous Galaxy S and Galaxy Note series devices, as well as the Galaxy Z series, Galaxy A series and Galaxy tablets.[2] This announcement comes alongside a new software update for the Galaxy Watch series[3] also available on December 6th that will enable users to enjoy enhanced fitness features and new watch faces.
