This is where the device’s user interface (UI) comes into play, with the experience of the users in interacting with it referred to as the user experience (UX). In 2018, Samsung introduced an improved version of its standard user interface and software overlay called ‘One UI’.

As well as working to make them intuitive, consistent, and effective, UX designers try to base user interface interactions on the way we use physical objects in the wider world to promote familiarity. For example, users turn a digital page in an e-book just like they would a physical page, or slide their cards up in the Samsung Pay app in a way that mimics how they would remove a card from their wallet. But what do UX designers do when there is no way to base interactions on real-world actions? Samsung Newsroom sat down with the designers of One UI to find out.

An Interface to Help You Stay on Task

The concept of One UI started with the idea to try and help the busy users of today stay focused by simplifying their interactions with their smartphones. One UI designer Soeyoun Yim explained that the process of designing the interface was undertaken based on the concept of ‘everyday simplicity’, saying that, “One UI was designed to help users focus on important tasks by eliminating distractions.”

Now, One UI has been further developed into ‘One UI 2’, which was unveiled at the end of last year. This upgraded interface incorporates the icons from One UI in new styles and configurations, and includes revamped colors and movements. In addition, One UI 2 makes the icons more conspicuous with distinct color tones and motions, for instance when the ‘settings’ icon trembles to let users know that an update is underway.

‘Simplicity’ – to Help You Focus on What Matters

Simplicity was the number one priority for the designers when developing One UI 2. To that end, the pop-up screens that appear at the top and bottom of the screen were made more compact and simplistic to keep users from getting distracted while making use of features.

The camera app has also been simplified to ensure that the basic operation of the app isn’t impeded, and prevent users from getting distracted while they’re taking their picture. Taehee Hwang, the UX designer responsible for the camera app, outlined how this makes the user experience more straightforward. “The basic photo and video modes can be accessed at the bottom of the screen, while special modes such as the Food and Night modes can be accessed by selecting or swiping through to ‘More’,” she related. “This simplifies what is displayed on the screen so that users can concentrate on taking their picture.”

‘Comfort’ – So Your Eyes and Fingers Can Take It Easy

Making user interactions more comfortable and facilitating one-handed use were also at the fore of the development of One UI 2. Whereas One UI designated the top and bottom sections of the screen as the ‘viewing’ and ‘interaction’ areas respectively, One UI 2 allows the majority of tasks to be completed within the lower area of the screen. Moreover, for actions that require interaction in the top part of the screen, unnecessary finger movements were minimized to improve comfort and convenience.

The same principles were applied to the keyboard, making it possible for users to perform other tasks while keeping their fingers within the keyboard area. For example, by long-pressing the space bar, users can now control the position of the cursor from within the keyboard window without having to interact with the main text body. In addition, users can swipe left or right with two fingers to undo and redo actions, and adjust the dimensions of their keyboard to better match the size of their hands.

The ‘dark mode’ feature has been shown to reduce eyestrain, and One UI 2 has expanded the number of apps within which it can be applied. “Dark mode has been expanded to a number of apps that it wasn’t previously accessible in,” said Yim, “To make it more comfortable to use devices in the dark we are also applying a darkening filter to background wallpaper displays.” Yim also spoke to the designers’ efforts to further ease eyestrain, relating that, “An algorithm has been incorporated that analyzes the background image on the lock screen and automatically shows the time in the color that will show up best against that backdrop.”

‘Convenience’ – Streamlining Rich Experiences

The ‘Single take’ feature comes with One UI 2 on the Galaxy S20 and is capable of using Ultra wide, Live focus, and short video features to deliver various photo styles and results, all with a single shot. “We started by asking ourselves two questions,” explained Hwang, “Firstly, how can we make sure the users enjoy the moment? And secondly, how can we deliver a variety of results without requiring the user to do more than take a simple, standard shot?”

While explaining what went into developing the feature, Hwang explained that, “Since this feature was to be introduced on the Galaxy S20, we decided that a help message should be displayed when the user entered Single take mode. Moreover, to allow the user to view a wide range of results simultaneously on the same screen we introduced a new kind of viewer.”

The video calling feature was also further upgraded with the integration of ‘Google Duo,’ Google’s simple, high-quality video calling app. Sueyeon Lee, the designer in charge of integrating Google Duo and One UI, elaborated on the designers’ efforts to improve convenience, saying, “Our goal was to make the user experience more convenient by making the features of Google Duo the default for Galaxy devices.”

Lee went on to highlight some other user experiences specific to Galaxy devices, remarking that, “5G video calls have been brought to smartphones for the first time with this integration, allowing users to experience FHD video calls and use AR emojis and wide screen mode within their video calls.” Lee finished by saying, “We will continue to develop advanced, integrated communication experiences linked to the phone, message and contact apps.”

The Galaxy Z Flip represents a totally new style of device with a revolutionary format. Thus, the question of how to provide top-tier usability and convenience on the new smartphone required the designers to think outside the box. Hyungwoo Shin, the designer responsible for developing the Galaxy Z Flip’s UI, outlined the development process, saying, “This is a whole new kind of device. We didn’t have access to any sample devices to which we could apply the new UI, so we had to print out screens, attach them to mock-up products and fold and unfold the devices to figure out how best to apply One UI.” In designing this special UI, the designers incorporated the ‘cover display’ aspect, which expands the interface onto the small screen on the outside of the phone that enables users to check the time, read notifications and take selfies when the phone is folded.

Special effort was put into developing the UI for the Galaxy Z Flip’s ‘Flex Mode,’ a feature that divides the screen into two halves when the phone is half-folded and set at a 90-degree angle. Shin explained how the design team catered to this unique form factor, saying that, “Designing a UI that would be suitable for a phone being used in Flex Mode presented a real challenge. We ended up creating a new layout that reflected the UIs seen on the foldable phones of the past.”

‘Accessibility’ – Fair and Available to Everyone

‘Accessibility’ means how easy to use and available a device’s features are to a wide range of users. The designers of One UI 2 worked to provide an equally accessible experience to everyone – regardless of age or disability – with features such as high contrast themes, which improve usability for visually impaired users. Samsung additionally consulted with differently-abled users to receive feedback on accessibility within the UI and to hear the users’ ideas on where there was room for improvement.

As a result, color adjustments and high-contrast features were implemented within the UI to expand usability to more differently-abled users. These changes also make it easier for users to access specialty features within the UI like Light Sensing, which detects nearby lights and informs the user of their status with vibrations, and Live Transcribe, which uses Bixby to transcribe audio messages and nearby noises.

One UI to Satisfy the Individual User

So, what’s next for the One UI design team? Since the first and second incarnations of One UI were about establishing the foundation of the interface, the next steps will focus on catering more to individual users. “Going forward, One UI will offer more customized content,” related Yim. “Active customization will be brought to bear to improve the individual user experience.”

As they continue their development work, the One UI designers will keep working to provide the best possible environment for Galaxy users, while ensuring that the interface is inclusive and makes inconvenience a thing of the past.

“Design” is a difficult word to define – it can encompass a range of meanings. Sometimes design is simply the shape of an object. At other times it is more abstract, like a user’s overall experience with a product. It can even be felt as an emotional resonance between the designer and the user.

Samsung Electronics designers take all these definitions into account when designing products. Their imaginations stretch from intangible elements, such as the UX (User Experience), to physical features, like the look and feel of the device.

Throughout the design process, all our designers have had a common goal in pursuing design that is “Inspired by humans, creating the future.” Samsung has long emphasized design as one of the company’s core assets, declaring 1996, “The year of the design revolution.” We want to tell a story about our philosophy and culture as well as our technology through our products, and to that end, we always put users at the center of design.

Designers meticulously designed the rounded edge of the Galaxy S10 to create a secure, comfortable grip. Galaxy S10’s new Infinity-O Display gives users a whole new experience when capturing footage or watching a video clip. Samsung’s One UI (User Interface) was devised to ensure consistent usability across all functions and services, allowing users to focus more on the important tasks. Designers carefully studied finger movements to ensure easy and fast access to key features of the device.

Change brings about new experiences. Not only does Samsung put users at the center of its design process, the company also deeply considers how to create meaningful change for users in their daily lives.

In 2019, millennials are the originators of social trends, and they value experiences over possessions. This generation boldly explores new discoveries and pursues individuality. Against this backdrop, we at Samsung are reaffirming our future direction, further committing ourselves to a user-centric design philosophy.

“Be Bold. Resonate with Soul.”

This motto illustrates our desire to nurture more compelling experiences and bring meaningful changes to users by creating bold and innovative designs. We aim to instill an authenticity and emotional resonance into our designs that permeates throughout people’s daily lives.

There are about 1,500 Samsung Electronics designers across the globe. These conscious pioneers will continue striving to make the world a better place as they design Samsung products, services, and technologies and deliver exciting experiences, meaningful stories and organic connections to users.

In light of modest global sales recently, some observers say that smartphone innovation has hit a bottleneck, as new devices bear more iterative upgrades instead of groundbreaking features. Others even predict that the smartphone era may be coming to an end soon.

But with mobile technologies like 5G, AI, and AR maturing rapidly, users will be able to do even more with their smartphones soon. Instead of losing relevance, the next wave of technological innovation will make the smartphone more central to our lives than ever before. Whether it’s leveraging increased connectivity or harnessing next-generation mobile intelligence, a larger display will be key to accessing future smartphone experiences.

Despite current trends, we are still living in a world where the size of the smartphone display can only be as large as the device itself. At Samsung, we began to ask ourselves how we can overcome this limitation and expand the possibilities of what users can accomplish on the go.

The Shape of Things to Come

Smartphone displays can’t get any larger without compromising portability – this was the orthodoxy for a long time.

Instead of accepting the status quo, resolving the contradiction between screen size and portability and developing a new form factor became the central focus of our innovation efforts.

The recent unveiling of the Infinity Flex Display at SDC 2018 signaled the start of this new chapter. But building a foldable device was no mean feat. After the prototypes of the flexible display debuted at CES in 2011, it took another seven years to perfect the technology and deliver a truly meaningful experience to users. From developing new materials to overcoming mechanical challenges, the foldable screen demanded a total reconfiguration of the smartphone from inside out.

Preparing for the New Era

We expect to see a sea change in the smartphone form factor in the coming years. From rollable and stretchable devices to the devices that can fold in multiple ways are no longer beyond the realms of reality. Samsung is ready to usher in this future and create meaningful experiences for consumers that help them do more of what they love.

To build the new foldable device, we made significant investments to create a new material that completely changes the anatomy of the smartphone display. We also created a natural and durable folding experience that users can appreciate from the very first time they unfold the device and crafted an innovative mechanical technology that can withstand hundreds of thousands of folds. We also had to rethink the placements of the battery, cooling system, and camera so that they can be placed inside the slim body efficiently. Last but not least, we developed an intuitive UX to ensure apps can transition seamlessly between the smaller and larger displays. We are committed to continue pushing the limits of possibility and lead the mobile industry into a new era.

Smartphone innovation is at the cusp of the next major transformation. The arrival of the Infinity Flex Display is just the beginning. We will continue pushing the limits of possibility and shape the future as it unfolds.

From touch-based controls to voice commands, Galaxy’s UX has continuously reinvented the way we interact with mobile devices. Building on a legacy of cutting-edge innovations, Samsung’s One UI promises to make the smartphone experience more flexible and responsive to our needs than ever before.

Take a look at the infographic below to learn more about the evolution of Galaxy’s UX.

Lock Screen and AOD

The lock screen is the part of the smartphone we interact with the most. It’s often one of the first things we see when we wake up and check throughout the day. Galaxy S9 and S9+’s lock screen features give you the best platform to tell your own story every day. With the video wallpaper function, you can customize the lock screen to play your favorite images to keep you inspired all day long. The feature even lets you transform your treasured Super Slow-mo videos into lock screen wallpapers. You can also try making the notification bars on the lock screen transparent to see all the things that matter to you more clearly.

Whenever you need to read the time precisely, simply tap the clock on the lock screen and it will tell you the seconds as well as minutes and hours.

Edge

There’s nothing more frustrating than trying to find an app quickly only to forget which folder it’s in. The Edge function on the Galaxy S9 and S9+ solves this problem by giving you the option to store your favorite apps and contacts on the side of the Super AMOLED screen. Samsung has improved the function to facilitate quicker access. Simply drag and drop an icon from Apps Edge to a designated box for a pop-up view. The Edge function on Galaxy S9 and S9+ also allows you to quickly reply to messages in a pop-up window.

You can now switch between Apps Edge, People Edge and Smart Select with a simple swipe. People Edge allows you to easily call or message your frequent contacts, while Smart Select lets you capture an area of your screen as an image or animation.

App Pair

We’ve all been there. Switching back and forth between different documents and apps to gather all the information while writing an email on the go. The time spent navigating multiple apps could make writing a simple message feel like running a marathon. With App Pair on Galaxy S9 and S9+, you’ll never find yourself in such a situation again. With just one touch, the function launches two apps simultaneously in Multi-Window mode. You can even place the customized App Pair icon on the home screen to ensure easy access all the time.

Landscape Mode

Most multimedia contents are best experienced in landscape on the smartphone. Using the entirety of the screen, the experience becomes more immersive. But switching from a video stream to other tasks can be cumbersome at times, as the home screen is usually fixed in portrait – until now. The home screen of Galaxy S9 and S9+ can rotate to landscape automatically, which means you don’t have to physically change the phone’s position whenever you transition between multimedia contents and other tasks.

Dedicated Fingerprint

Our phones often hold highly personal information. While it’s important to have such data locked away securely, efficient authentication is equally crucial. Galaxy S9 and S9+ strike the perfect balance between security and usability with Dedicated Fingerprint. The function lets you register two fingerprints to unlock the phone. Your normal fingerprint takes you to the home screen while your dedicated fingerprint gives you access to the Secure Folder directly from the lock screen.

Take the Galaxy S8 and S8+. When designing its latest flagships, Samsung went to great lengths to ensure that the UX behind their groundbreaking, bezel-less designs would foster convenient and intuitive interactions. The result of the company’s efforts is a seamless interface that allows users to navigate the devices’ immersive displays with ease and take full advantage of their powerful features.

The tips and functions outlined below offer simple ways for users to further amplify their Galaxy S8’s convenience and get more out of their smartphone experience.

Get to Know the Navigation Bar

The navigation bar that houses the Galaxy S8’s Home, Back and Recents buttons has a few tricks up its sleeve, including allowing users to bypass their device’s Lock screen and instantly access the Home screen.

After activating the Unlock with Home button feature via Settings > Display > Navigation bar, a hard press of the square Home button from the Always On Display will unlock the device (a swiping motion is not required), while a double-tap will pull up the lock screen. The navigation bar’s settings also allow users to customize the Home button’s sensitivity to avoid unwanted presses.

Users may hide the navigation bar in apps where it does not automatically disappear or fix it to their screen by toggling the Show and Hide button, which appears on the bar’s far left side. The bar’s configuration may also be customized.

Using certain apps and functions may cause the navigation bar to disappear entirely. In those instances, users may navigate back to the Home screen by hard-pressing on the Home button’s usual location, and may access the navigation bar by swiping up from the bottom of the screen.

Take Advantage of the Edge Screen

The Edge panels in the Galaxy S8’s Edge screen offer access to apps, news and key functions with a simple swipe of the side of the screen. Users may customize their Edge panel selection and add more apps and shortcuts that work for them.

The Edge screen’s Edge lighting feature adds additional convenience, notifying users of incoming messages by illuminating the Infinity Display’s edges. This allows notifications to be visible even when the device is facing down, and creates an intuitive means to notify users of messages without disrupting their enjoyment of videos, games and apps.

Users may access the Edge screen’s settings by tapping Settings > Display > Edge screen.

Create Convenient Reminders

Find an interesting article that you’d like to get back to later? The Galaxy S8 allows users to conveniently save URLs using its Reminder function.

With the website pulled up, simply access your browser’s sharing options and tap on the Reminder icon. Webpage URLs are automatically saved, and users may additionally select exactly when they’d like to receive their notification.

The Galaxy S8 also allows users to create reminders based on texts. When viewing a conversation in the Messages app, long-press your selected message until the Message options menu appears and choose Send to Reminder. The message will automatically be saved to the Reminder app, and you’ll also be able to specify if/when you would like the reminder to appear.

In addition, the Galaxy S8 allows users to pin reminders to its Always On Display, making them visible at all times. To do so, open the Reminder app, tap on the reminder that you would like to display and select Pin to Always On Display.

Power Button and Sensor Shortcuts

Sometimes taking the perfect photo requires one to be quick on the draw with their camera.

To help users capture more of their special moments, the Galaxy S8’s camera launches instantly with a double-press of the power key. The camera’s zoom function is similarly seamless, allowing users to easily zoom in or out by dragging the white shutter button to the right or left.

In addition to unlocking the device, the Galaxy S8’s fingerprint sensor allows users to open apps and manage key functions. A simple swipe down or up will show or hide the notification panel, while swiping up on the sensor from the Home screen will launch the Samsung Pay app. The function may be found under Settings > Advanced features > Finger sensor gestures.

In a meeting and can’t answer the phone? With the Galaxy S8, you can politely decline incoming calls with preset text messages.

The Quick Reply feature activates with a two-second touch of the device’s heart-rate sensor and allows users to send a customized response that suits their needs. The function may be found under Settings > Display > Edge screen > Edge lighting > More Options > Quick reply.

Step Up Your Screenshot Game

The Galaxy S8 allows users to snap quick screenshots via a variety of convenient ways.

Users have the option to press and hold the ‘volume down’ and power buttons simultaneously, swipe the screen from one side to the other with the side of their palm, or utilize the Galaxy S8’s Smart Select feature, which is found via the Edge screen and allows you to select an area of the display to capture as an image or GIF.

Located under Settings > Advanced features > Smart capture, scroll capture is another useful option that’s designed to help users snap more complete screenshots. The function appears after a screenshot has been taken and allows for all of an app or page’s scrollable content to be included in the image.

Get More Done with Snap Window

The Galaxy S8’s new Snap Window feature allows users to select a portion of the most recently opened app to pin to the top of their screen.

This means that, for instance, a user may keep an eye on a video or constantly updated content such as stock prices and headlines via the top of their screen while using the remainder of the display to send an email, browse the web or manage other apps.

Activate the feature by pulling up your recent apps and tapping on the function’s corresponding button.

A Fun Way to Unlock Your Phone

After registering their irises for biometric verification, Galaxy S8 users have the option to select a fun mask or background to display when the security feature is activated.

Available designs may be found under Settings > Lock screen and security > Iris scanner > Preview screen mask.

Sharing Links with Samsung Cloud

Samsung Cloud offers users an effortless means to share large video clips and reams of pictures by creating a URL that lets others access your shared media.

The function maintains full picture quality and supports files of up to 1GB in size. Users may save up to 2GB of content per day. After two days, the files are deleted from Samsung’s servers.

To utilize the feature, select the photo or video that you would like to share in the Gallery app, tap Share and choose Link Sharing. The subsequent screen will allow you to select the app you would like to use to send your link.

Users may also provide others with access to shared content by sending a code. Those who receive the code will be able to punch it in to Samsung’s Link Sharing app and instantly view and download the shared files.
