Galaxy Tab S8, Tab S8+, Tab S8 Ultra, Tab S7, Tab S7+, Tab S7 FE, Tab S6 Lite, Tab A8, Tab A7 Lite, Tab Active3 and Tab Active4 Pro users are also set to enjoy several new user-centric features as part of the One UI 5.1.1 update. In addition, Galaxy Watch5, Watch5 Pro, Watch4 and Watch4 Classic users will experience key updates from the One UI 5 Watch update.

Read on to learn more about how these latest updates are set to deliver a whole new level of innovation and productivity direct to your fingertips.

Open Up New Ways to Interact With Your Device

One UI 5.1.1 helps Galaxy Z Flip4 and Z Fold4 users enjoy their favorite media and content easier than ever with Flex Mode,² thanks to a range of enhanced features and functionalities.

This upgrade now makes it simpler for you to show or hide your Flex Mode Panel. When folding your phone in Flex Mode,² the panel’s icon will float up the screen, allowing you easy access. Enjoy a more personalized Flex Mode Panel experience by simply dragging and dropping the icon on the toolbar. This customizable panel provides users with easy access to features such as Multi Window,³ touchpad, screen capture and more.

With the new update, the media play bar button — complete with a 10-second fast forward and rewind and features access — is showcased in one convenient place when the Flex Mode Panel activates. You can also press down for easier scrubbing through your media’s progress bar. When you’re enjoying a movie in Flex Mode,² you can make the most of your favorite content by rewinding or fast-forwarding with just a single tap with your personalized Flex Mode Panel Tool Bar. Or, you can open a new Multi Window³ to reply to a message or browse for reviews online, all without interrupting your viewing.

Do More At Once For More Versatile Device Experiences

The multitasking experience for foldables and tablets is set to improve. While enjoying a video using your Galaxy Z Fold4, Z Flip4 or Tab S8, you can easily open Samsung Internet in a pop-up window to search for something, all while your content still plays. When you’re done browsing, the window can be easily dragged to the edge of the screen, where it will now snap seamlessly into place. If you want to access Samsung Internet again, simply tap the pop-up to open the window to its previous location.

Intuitively switch from the pop-up window to Multi Window³ by pressing and holding the handle at the top of the pop-up window. The new update supports more effortless launch and control of your screen, allowing you to seamlessly switch to split view and easily control your screen through a simple long-press of the pop-up view handle.

Two-handed drag and drop⁴ is now supported on your foldable and tablet’s main screen, allowing you to open your desired app with one hand and then use the other to drag a file, app icon or other item into your target folder or location. This update makes it even quicker to seamlessly share multiple photos from your Gallery with a friend via a messaging app.

With the latest update, Galaxy Z Fold4 and Tab S8 users can unlock next-level productivity for both work and play thanks to innovative additions to the Taskbar.⁵ Now, the Taskbar⁵ enables lightning-fast task switching with access to up to four recent apps.

Take Your Wellness Journey To The Next Level And Express Yourself With Galaxy Watch⁶

The One UI 5 Watch update is bringing more personalized wellness features⁷ designed to help you achieve a healthier you, as well as more customizable style options that are able to match perfectly with your lifestyle, to the Galaxy Watch5 and Watch4 series.

With the upgraded sleep management feature,⁸ users are able to better understand their personal sleep patterns through a more intuitive UI with detailed analysis of Sleep Score Factors,⁹ Sleep Consistency and Sleep Animal Symbols.¹⁰ Users can also access Sleep Coaching¹⁰ right from their wrist, empowering them to track their progress more conveniently and stay motivated throughout the day.

Furthermore, maintaining a sleep-friendly environment is important for a restful night of sleep. When it’s time for bed, your Galaxy Watch can help set the optimal sleep environment by automatically adjusting the settings of connected home devices.¹¹ In addition, when Sleep Mode is turned on, the invisible LED infrared sensor on the watch activates to minimize even the smallest of distractions.

The One UI 5 Watch update empowers you to enjoy personalized fitness tools that allow you to set your own fitness goals — and to achieve them. The Personalized Heart Rate zone feature analyzes your physical capabilities¹² and establishes five optimal running intensity levels, and in addition to the existing more than 100 existing workout trackers, you can now record your runs on the track with Track Run and even build and track your own workout routine with the Custom Workout feature. For Galaxy Watch5 Pro users, even more enhanced GPX features¹³ are available, with users now able to explore and conquer new routes more conveniently through the GPX File Database.¹⁴ In addition, you can easily search and download various GPX route files around your location. The Route Workout feature has expanded to support running and walking as well as hiking and cycling.

Galaxy Watch users are set to experience even more enhanced health monitoring thanks to the Irregular Heart Rhythm Notification (IHRN)¹⁵ feature. IHRN is now available to these Galaxy Watch5 and Watch4 series users,¹⁶ providing them with more comprehensive heart health insights.

What’s more, Galaxy Watch5 and Watch4 users have access to an even greater selection of stylish and informative watch faces¹⁷ able to perfectly match their style and goals. Coming this fall, Galaxy Watch Active2 and Galaxy Watch3 users, too, will be able to enjoy some of these new watch faces — Stretched time and Perpetual — in order to express themselves with style.

Enhanced Galaxy Ecosystem Experience¹⁸

The latest One UI update is optimizing smartphone camera control for users. With the addition of a dedicated quick access button on your Galaxy Watch, you can more easily remote control your paired Galaxy Z Flip4’s camera directly from your wrist to seamlessly switch camera modes and even zoom in or out.

Samsung Electronics today announced that the Irregular Heart Rhythm Notification (IHRN) feature¹ on the Samsung Health Monitor app² will soon be available in 13 markets starting this summer. Combined with the app’s Blood Pressure³ and Electrocardiogram (ECG)⁴ monitoring, the IHRN feature detects heart rhythms suggestive of atrial fibrillation (AFib), helping Galaxy Watch users understand their heart health more comprehensively.

The IHRN feature has been approved by the Korean Ministry of Food and Drug Safety (MFDS) last week, following recent clearance by the U.S. Food and Drug Administration (FDA). It will also be introduced in Argentina, Azerbaijan, Costa Rica, Dominican Republic, Ecuador, Georgia, Guatemala, Hong Kong, Indonesia, Panama, UAE, as well as Korea and the U.S., taking the total to 13 markets.

Alongside the on-demand ECG tracking, the IHRN feature checks for irregular heart rhythms in the background and warns the user of potential AFib activity. Together with the existing Blood Pressure and Heart Rate⁵ monitoring, users can gain even deeper insights into their cardiovascular health.

Since the launch in 2020, the Samsung Health Monitor app has expanded to 74 markets⁶ across the globe. Over 15 million Galaxy Watch users have kept track of their blood pressure and ECG right from their wrist, gaining a better picture of their heart health by continuously monitoring and recording their blood pressure and heart rhythms.

“Cardiovascular disease remains one of the main causes of death around the world, and we’re committed to empowering our users to stay informed about their heart health by providing monitoring tools, including blood pressure measurement and irregular heart rhythm notification,” said Hon Pak, Vice President and Head of Digital Health Team, MX Business at Samsung Electronics. “We’re constantly exploring new ways to help Galaxy Watch users obtain deeper insights on their health and wellness effortlessly, day and night.”

The Irregular Heart Rhythm Notification feature will first be available on the upcoming Galaxy Watch devices later this year, as part of the new One UI 5 Watch and later expanded to previous editions.⁷

¹ The IHRN feature is not intended to provide a notification on every episode of irregular rhythm suggestive of AFib and the absence of a notification is not intended to indicate no disease process is present. It is not intended for users with other known arrhythmias.

Due to market restrictions in obtaining approval/registration as a Software as a Medical Device (SaMD), it only works on watches and smartphones purchased in the markets where service is currently available (however, service may be restricted when users travel to non-service markets). This app can only be used for measuring in ages 22 and over.
³ The Blood Pressure feature is only available in select markets. To ensure accuracy, users should calibrate their device every four weeks with a traditional blood pressure cuff. The BP feature cannot diagnose hypertension, other conditions or check for signs of a heart attack. It is not meant to replace traditional methods of diagnosis or treatment by a qualified healthcare professional.
⁴ The ECG feature is only available in select markets. It is not intended to replace traditional methods of diagnosis or treatment. The feature is not intended for users with known arrhythmias other than AFib. Users should not interpret or take clinical action based on the device output without consultation of a qualified healthcare professional.

“Samsung is dedicated to delivering a comprehensive health experience and empowering users to reach their wellness goals. Now more than ever, we believe this starts with getting a good night’s sleep,” said Hon Pak, Vice President and Head of Digital Health Team, MX Business at Samsung Electronics. “The new One UI 5 Watch continues our ongoing commitment to help people improve the quality of their sleep, so they can start each day fully recharged and ready for the day.”

Better Sleep: Essential to Better Health

Samsung has focused its efforts on three key elements for better sleep: understanding personal sleep patterns, building healthy habits and establishing a sleep-friendly environment. One UI 5 Watch delivers on these elements with an even more complete sleep experience.

The new Sleep Insights UI prominently displays the user’s sleep score to provide a clearer snapshot of the prior night’s rest, followed by related metrics like sleep phases, snoring hours and blood oxygen levels. In addition, Sleep Coaching — tailored around eight different sleep types² — also becomes fully accessible directly on Galaxy Watch as well as a paired phone, making for a more convenient and motivational way for users to track their habits anytime, anywhere.

Creating a comfortable environment can make all the difference in sleep quality, and even small distractions can have outsized impacts. That’s why Samsung has made it easier to connect Galaxy Watch to a wide range of devices. Once the user’s Galaxy Watch detects that they have fallen asleep, SmartThings lets the user switch off their connected devices to create a more conducive environment for rest. Sleep Mode swiftly mutes notifications and dims the user’s phone and watch screens, and One UI 5 Watch builds on this feature by now utilizing an infrared sensor rather than a green LED light to further minimize distractions. 

A Smarter Fitness Partner

Personalized Heart Rate Zone has been added to Galaxy Watch’s various tailored running tools — including real-time running analysis and a customized interval training program. This new feature analyzes individual physical capabilities³ and sets five optimal workout intensity levels (warm-up, fat burn, cardio, hard-training and max. effort). This enables users to set their own goals based on their ability, from burning fat to high-impact cardio.

Outdoor activity enthusiasts with Galaxy Watch Pro can look forward to additional benefits, starting with an expanded Route Workout — which now supports running and walking alongside previously available hiking and cycling route options. Galaxy Watch Pro users can also search and access the GPX File Database directly via Samsung Health app, and receive recommendations on new routes based on inputs like location, time, rating or popularity.⁴

Safety First, Always On

Safety is a must when it comes to health and wellness, and One UI 5 Watch also offers improved tools for greater peace of mind. Updates to the SOS feature enable direct communication to an emergency service number to relay information on the wearer’s location,⁵ and also allow immediate access to the wearer’s Medical Information once an SOS is activated. In addition, Fall Detection is now activated by default for users of advanced ages⁶ to help lower the risk of emergencies. These are just some of the examples of Samsung’s ongoing efforts to enhance user safety.

One UI 5 Watch will be available first on the upcoming Galaxy Watch series later this year with further updates to be announced soon. Galaxy Watch5 and Galaxy Watch4 series users in the U.S. and Korea can register for the beta program starting in May via Samsung Members app. 

¹ Availability of the features may vary by market, carrier, model and the paired smartphone. The features are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment or prevention of disease.
² For sleep pattern results, user must wear watch while they sleep for at least 7 nights and complete a survey.
³ After 10 minutes of running, Galaxy Watch calculates Personalized Heart Rate Zone based on VO2max and aerobic/anoxic thresholds.
