The AMOLED Display: Bigger Is Better

One of the major benefits of a smartphone is that it allows users to enjoy content on a large screen with clear picture quality that sits right in the palm of their hand. Samsung kicked off the trend of the large screen era in the smartphone industry with the introduction of their AMOLED display. This display, developed using Active Matrix Organic Light Emitting Diode (AMOLED) technology, is characterized by its clear picture quality, self-luminescence and larger screen size.

The Samsung Galaxy S was the world’s first smartphone to be launched with a Super AMOLED display, an ultra-thin screen that consumes less power and provides crisper and more vivid picture quality. With the introduction of the Galaxy S in 2010, users’ interest became piqued in obtaining bigger screens — such as the 4- to 5-inch screens of the AMOLED display compared to the conventional 3-inches on other phones — on which to fully immerse themselves in their favorite content.

Samsung has continued to take its AMOLED technology to the next level by unveiling devices with more powerful and more advanced screens, such as the Galaxy S10, the world’s first mobile device with a High Dynamic Range10+ (HDR10+) supported Dynamic AMOLED display, and the Galaxy S21 series, which features a Dynamic AMOLED 2X display with an automatic refresh rate of up to 120Hz based on the content type. Samsung’s innovative technology has enabled silky-smooth scrolling and uninterrupted viewing experiences, even on larger screens.

The Galaxy Note and S Pen: Adding Analog Touch to Digital Devices

As of 2011, it became no longer necessary to keep notebooks and writing instruments in our bags at all times. With the introduction of the Galaxy Note equipped with S Pen, it is now possible to save and share everything from memos to drawings right on our smartphone’s screen. At that time, the Galaxy Note was launched with an S Pen that supported 256 levels of pressure onto the device’s large screen. Since then, both the Note and the S Pen have become inseparable, and as the series has developed, both have evolved significantly.

For example, Samsung introduced Air Command for the Galaxy Note 3 to give users easy access to signature S Pen features when hovering their S Pen over the screen. The company also then incorporated Bluetooth Low Energy (BLE) technology into the Galaxy Note 9 S Pen so that its stylus pen could also function as a remote control. For the Galaxy Note 10, the addition of Air Action features enabled users to remotely control their device when switching camera modes or zooming in or out, a marked change from previous models which only permitted users to take photos from a distance. In line with this innovative spirit, Samsung introduced the artificial intelligence (AI)-powered S Pen for the Galaxy Note 20 in order to provide users with a more delicate and sophisticated drawing experience, and as of last year, the innovative S Pen is now available on devices such as the Galaxy S21 Ultra and Galaxy Z Fold3 to expand its compatibility.

Samsung Knox: Your Trusted Mobile Bodyguard

We are now living in the era where most of our daily tasks and experiences can be undertaken all with a singular smartphone, meaning that the importance of security cannot be overemphasized. Samsung Knox has become a reliable shield for users concerned about information leakage or virus penetration.

Samsung Knox, installed on Galaxy devices since the Galaxy Note 3 in 2013, protects devices on a step-by-step basis from the chipset to the operating system (OS) and application level, while also blocking hacking and unauthorized access. In addition, thanks to its encrypted container space, a user’s personal and business data can be separated and managed safely.

In 2021, the company launched Samsung Knox Vault with the Galaxy S21 in order to thoroughly ensure the protection of ever-growing amounts of data. In addition to offering the industry’s highest level of security chipset (eSE, or embedded Secure Element) and a secure processor that prevents HW-level attacks, Samsung Knox Vault features a tamper-resistant security memory to protect a user’s various passwords and biometric information.

Superb IP Rating: Ultimate Protection From Dust and Water

In the early 2010s, if you accidentally dropped your smartphone while using it in water, nothing but despair awaited you. To mitigate this, Samsung expanded the horizon of smartphone experiences by applying waterproof and dustproof functions to the Galaxy S5 for the first time in 2014.

From the Galaxy S7 in 2017 onwards, IP68,¹ the highest waterproof and dustproof rating, has been applied to Galaxy devices in order to strengthen their performance. The IP68 rating is given to devices after testing in fresh water at a depth of 1.5m for 30 minutes. Galaxy users are now able to use their smartphones with peace of mind thanks to strong waterproof and dustproof technologies.

#5. 2015
Samsung Pay: A Mobile Wallet in Your Pocket

It is no exaggeration to say that, after 2015, the trend of going ‘wallet-less’ saw a surge in increase. At this time, Samsung introduced Samsung Pay, a mobile payment service that replaces the cash and credit cards in a user’s wallet. Since this service was first introduced on the Galaxy S6 in 2015, it has established itself as a core representational service of the Galaxy smartphone.

When using public transportation, as well as when out shopping, users need just touch their smartphone instead of having to get out their wallet to pay. These days, leaving the house without a wallet has become a normal habit.

#6. 2016
Advanced Camera Technology: The World’s First Dual Pixel Sensor

Smartphone camera technologies are advancing day by day, to the extent at which if you have a smartphone, you’re able to capture pictures and videos comparable to that of professionals.

In 2016, Samsung raised the smartphone camera function to a new level by installing the industry’s first dual pixel in the Galaxy S7. At that time, the dual pixel was an image sensor only seen in high-end digital single-lens reflex (DSLR) cameras. By increasing the amount of light received by both the front and rear cameras, the Galaxy S7 was able to focus quickly and accurately, as well as take optimal photos in dark environments.

Samsung then combined an Ultra-Wide angle lens and intelligent SW in the Galaxy S10 to help users take even sharper pictures. The Galaxy S20 features a remarkable four quad cameras, raising the level of camera functionality once again. In particular, the optical zoom performance has been greatly improved; Galaxy S20 Ultra users can harness the Space Zoom function to zoom in up to 100 times, allowing them to take clear pictures of the night sky.

#7. 2018
One UI: Making My Own Galaxy

One UI is an interface that supports the unique user experience of Samsung Galaxy, and was first introduced in November 2018.

By dividing the viewing area and the touching area, the layout of One UI allows users to comfortably perform all operations with just one hand, and all necessary essential functions are included concisely on-screen so that everyone and anyone is able to use it easily. One UI is also characterized by a unified user experience as it has been applied consistently to devices across the Galaxy ecosystem, including smartphones, tablets and wearables.

One UI 4, updated last year, harnesses a completely different color palette with which to decorate a device’s home screen, icons, notifications and wallpapers in your own style. In addition, One UI 4 features strengthened security features, such as allowing users to easily select what to share and what to keep private in order to keep up with users who increasingly value their individuality and their privacy.

#8. 2019
Galaxy Z Series: The Dawn of the Era of Foldable Smartphones

In 2019, Samsung pioneered the field of foldable smartphones by unveiling the world’s first Galaxy Z Fold, equipped with a 7.3-inch Infinity Flex Display.

Samsung’s newly developed hinge technology makes it possible to open and close the smartphone as smoothly as one opens a book, and offers users secure, long-lasting flexibility that passed a test to withstand 200,000 folds. In 2020, the company’s foldable lineup was expanding to include the Galaxy Z Flip, which features a compact design as the screen unfolds vertically.

Samsung not only pioneered a new form factor, but also new usability options through such functions as Flex mode, which allows for more usage scenarios by fixing the hinge at a specific angle, and Multi-Active Window, which can open and run apps at the same time with applications optimized for the foldable screen for a split screen view.

Last year, Samsung expanded their foldable lineup with the Galaxy Z Fold3, which saw the inclusion of an S Pen and waterproof and dustproof technology, and the colorful, pastel-toned Galaxy Z Flip3 Bespoke Edition, leading the era of foldable popularization.

An AI-Powered Eraser: Removing Unwanted Objects From Photos

As part of Samsung’s mission to expand the application of innovative AI technologies to all smartphones, the company introduced the Object Eraser feature that lets you remove any unwanted objects in your photos with just a touch.

The Object Eraser function, first introduced in the Galaxy S21 in 2021, is a photo editing tool that harnesses artificial intelligence. Simply by touching the object you want to remove from a photo and tapping the ‘object erase’ button, the object is deleted without the need for a separate editing program. Currently, this function is available on smartphones with One UI 3.1 or higher, such as the Galaxy S20 and Galaxy Z Fold3.

Samsung first applied its AI-powered interface, Bixby, to the Galaxy S8 in 2017, and now users can control their major Galaxy devices using only their voice. In addition, Samsung has been incorporating AI technologies into its device OS, battery and camera in order to improve performance and convenience.

Galaxy for the Planet: For a Sustainable Future

Samsung is fully committed to minimizing the environmental impact of its products throughout the entire lifecycle of its smartphones, from the design to the production stage through to their usage and disposal, in order to ensure that Galaxy smartphones contribute to greater environmental sustainability. Under the sustainability vision of its Mobile eXperience (MX) Business, “Galaxy for the Planet,” Samsung is consistently working to achieve a circular economy by reusing and recycling resources in order to build a better Galaxy ecosystem.

One such effort towards sustainability is a reduction of plastic usage in smartphone packaging. The percentage of plastics used in the Galaxy S21 packaging accounts for a mere 4 percent of the total weight, cutting down the waste generated per packaging unit by 49 percent as compared with that of the Galaxy S7. In addition, the Galaxy S21 packaging contains only 58 percent of the paper used in that of the Galaxy S7, helping save some 44,802 trees a year. Samsung plans to exclude plastic materials in its product packaging and apply recycled materials to all of its products in the MX division by 2025.

The products set to be unveiled at Galaxy Unpacked 2022 are drawing attention thanks to the revelation that they have been designed using eco-conscious materials recycled from marine waste. Samsung has succeeded in transforming discarded fishing nets, a major contributor to marine pollution, into a material with which to produce smart devices, and the company plans to apply this material to all its products in the future.

¹ IP (Degree of Ingress Protection, IP Code) is a product-related protection technology standard established by the IEC (International Electrotechnical Commission) and is applied to various IT products and industrial devices. IP68 is the highest rating for dust and water resistance. Ip68 has a waterproof function that can withstand 1.5m of clear water for 30 minutes, but it is recommended that the device be washed off immediately after contact with water and then dried.

“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.”

And with reimagined widgets that offer even deeper customization, it’s never been easier to put your own personal stamp on your smartphone experience. You can even more effortlessly express yourself with a wider variety of emoji features, GIFs and stickers available directly from your keyboard.

Protect What Matters Most

There’s no privacy without strong security. That’s why, with One UI 4, Samsung is bringing 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 is simple.

Connecting You to an Extended Ecosystem

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

Samsung’s partnerships with other industry-leaders, like Google, ensure seamless experience when using your favorite third-party apps and services. This means you can enjoy apps like Google Duo, which provides high-quality video calls with friends and family.

And whether you’re using a Galaxy Z Series, Galaxy Watch or Galaxy Tab, you’ll get the uniformed look and feel across your devices, and will be able to seamlessly sync them.

² Galaxy Watch, Galaxy Watch Active, Galaxy Watch Active2 and Galaxy Watch3

Unlike in the past when cellphones had physical buttons and a limited number of features, smartphones now offer a wide range of functions that we access by interacting with our devices’ touchscreens. However, using the same component that serves as the device’s viewing medium for the primary input tool can sometimes present difficulties for users.

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? 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 Soyeon Lim 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 Lim, “To make it more comfortable to use devices in the dark we are also applying a darkening filter to background wallpaper displays.” Lim 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 Lim. “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.

Designed to simplify and streamline interactions, One UI has brought a unified mobile experience to Galaxy devices. Since its launch, Samsung has been refining the UX, while also expanding its capabilities to help users focus on the tasks that matter. Features are further enhanced to make the experience more natural, seamless and efficient. Below are a few key features of One UI and Android 10 we are excited for users to test on the Galaxy S10.

Focusing on What Matters

The clean and easy-to-use interface allows users to enjoy minimized pop-ups, embedded loading indicators and simplified button arrangements. The new One UI features a streamlined design where notifications take up less space, so users are kept up-to-date while being able to focus on the task at hand. You stay focused while enjoying your favorite content in full screen and never miss any essential information.

Caller notification and volume bar are minimized.

Making the Mobile Experience Visibly Comfortable

The new, smarter layout provides a visually comfortable experience. An enhanced Dark Mode helps users at night by intelligently adjusting the brightness of images, texts and colors on the display while reducing battery consumption.

Smart Lock screen automatically adjusts the color and format of the clock and notifications to ensure you can always see the text and icons clearly.

Updated One UI (R) expands Dark Mode to home screen.

Smart Lock screen automatically adjusts the color of the text on the lock screen

Keeping Digital Wellness in Check

The expanded One UI provides a wide range of tools to help you manage your digital wellness. Focus Mode lets you pause apps temporarily for times when you need to minimize distractions and get in the zone. By tracking usage, managing screen time or enabling focus mode to minimize distractions, users can ensure they are being efficient.

Maintaining the performance of your smartphone is easier with the intuitive Device Care menu, which gives you quicker access to the essential functions. Some individual features are also enhanced to give you more control, such as keeping or deleting duplicate photos.
