In the second part of this two-part series, Samsung Newsroom will dive into the remarkable technologies crafted by Galaxy developers and explain related terminology for everyone to understand.

Dynamic AMOLED 2X

Dynamic AMOLED 2X is Samsung’s latest and most advanced mobile display, building upon the original Dynamic AMOLED introduced in 2019. This enhanced version is tailored for high-speed gaming and multitasking, boasting a 100% accurate DCI-P3 color gamut for optimized colors and contrast. The display delivers a seamless user experience with smoother scrolling, excellent response times and HDR10+ certification. Notably, the adaptive refresh rate has been upgraded from 60Hz to 120Hz, further enhancing display performance.

Adaptive Refresh Rate

This technology is designed to offer a smooth and seamless scrolling and viewing experience by automatically adjusting the screen’s refresh rate based on the content being displayed. This feature not only ensures a smoother user experience but also optimizes battery life.

Auto Framing

Auto Framing is a feature that automatically adjusts the Galaxy device’s camera angle based on the number of people in the picture. The view narrows when there is one person and widens when the camera detects at least two people in the frame. Moreover, the screen follows the movement of the detected photographer, allowing for a trackable distance of approximately two-and-a-half to three meters and a trackable speed matching a normal walking pace. With this feature, capturing dynamic scenes like people dancing or children playing is a breeze. Users can ensure everyone in a large group fits within the frame using the Auto Framing feature and Flex Mode.

Nightography

Nightography is a powerful camera capability introduced for the first time with the Galaxy S22 that enhances color vibrancy and picture quality even in low-light environments. This feature captures a series of images and employs multi-frame processing (MFP) technology to analyze and eliminate noise and blurry shots. Nightography applies an HDR effect to the refined images, combining them into a single clear photo. Colors and details are enhanced using an AI image signal processing (ISP) algorithm. Using the Super Night Solution, users can take bright and crips videos without any visual noise.

Nit

Derived from the Greek word “nitere” meaning “to shine,” nit is a unit of luminance used to measure the light emitted from a smartphone or computer display. More specifically, one nit is the brightness of one candle in an area of one square meter, while 1,000 nits equals the brightness of light emitted by 1,000 candles in an area of one square meter. Since smartphones are often used outdoors, luminance is important to ensure the displays remain clearly visible in varying lighting conditions.

Fast Wireless Charging 2.0

Fast Wireless Charging 2.0 is Samsung’s wireless charging technology standard that operates on a magnetic field-induced fast-charging mechanism.

Initially showcased at Galaxy Unpacked 2015 when the Galaxy Note5 was introduced, the earlier Fast Wireless Charging could support wireless charging of up to 9W. Now, Fast Wireless Charging 2.0 enables faster wireless charging options of 10W, 12W and 15W.

In this two-part series, Samsung Newsroom will dive into the remarkable technologies crafted by Galaxy developers and explain related terminology for everyone to understand.

IP Rating

IP, or ingress protection, is a standard that measures a device’s ability to resist the elements. The first digit in an IP rating denotes the level of defense against dust and foreign particles, while the second digit represents the level of safeguard against liquids — the higher the digit, the better the protection. The Galaxy Z Fold3 and Z Flip3 were the first foldable products to achieve the IPX8 rating, followed by Z Fold4, Z Flip4, Z Fold5 and Z Flip5.

Flex Window

Flex Window, the Cover Screen of a Galaxy Z Flip device, was first included in the Galaxy Z Flip5. The display allows users to take photos, reply to messages or play content without opening the phone.

Flipsuit Case

This is an accessory for the Galaxy Z Flip5 that uses near-field communication (NFC) technology. When a Flipsuit card is inserted into the case, the Flex Window plays content linked to the card.

FlexCam

FlexCam is a camera feature using Galaxy Z 5’s Flex Window and the high-quality rear camera, allowing users to take pictures from various angles without opening the phone. Plus, convenient hands-free shooting is possible when Flex Mode and the Cover Screen camera are activated.

Multi Window

This feature enables users to open multiple windows on the Galaxy Z Fold display, supporting up to three at once. Multi Window offers a multitasking experience to simultaneously perform various tasks such as streaming, shopping, browsing the web and playing games.

Swipe Gesture

Swipe Gesture is a handy feature that lets a user control the Galaxy foldable screen through finger gestures. For example, split the screen horizontally and open a new app by swiping up with two fingers from the bottom to the top. These intuitive gestures enhance multitasking efficiency, providing an optimal way to operate the device.

Ultra Thin Glass

Ultra Thin Glass (UTG) is a crucial component of Galaxy foldable displays. The material’s exceptional thinness allows for flexible bending — at the same time, it possesses scratch-resistant properties, characteristic of traditional glass.

Flex Hinge

The Flex Hinge is the component that allows a Galaxy foldable to be folded and unfolded, enhancing the phone’s durability and enabling the functionality of Flex Mode.

Flex Mode¹

When partially folded, the Galaxy device will go into Flex Mode. Users can set their foldables on a flat surface without needing a separate phone stand to conveniently watch a movie, write an email or video call a friend.

Flex Mode Panel

Flex Mode Panel allows for seamless use of the control panel while enjoying videos, music or other content when the Galaxy foldable is set in Flex Mode. This feature can be activated in Labs.

Taskbar

The Taskbar conveniently presents Favorites and shortcuts to recently used apps at the bottom of an unfolded Galaxy display — allowing users to easily switch between apps and enjoy a seamless multitasking experience, much like they would on a PC.

Under Display Camera

The Under Display Camera (UDC) achieves a truly full-screen display by concealing the Galaxy Z Fold’s camera beneath the screen. With UDC, the front camera is seamlessly integrated to eliminate the need for notches or holes in the display. Samsung initially introduced the cutting-edge UDC technology in the Galaxy Z Fold3 and has continued to implement it in the Z Fold4 and the latest Galaxy Z Fold5.

¹ Flex Mode is supported at angles between 75° and 115°.

Once revolutionary in the mobile landscape, flip phones are now an integral part of our daily lives. From their early inception to modern iterations like the Galaxy Z Flip series, these iconic devices have transformed how we communicate, interact and express ourselves. Over the years, the Galaxy Z Flip has evolved from a compact communication device to the ultimate tool for unleashing your creativity — empowering users to unfold a world of possibilities with a simple flip. Samsung Newsroom sat down to detail the journey of how this groundbreaking series pioneered a new era of mobile innovation.

Following the ground-breaking launch of the Galaxy Z Fold, which has taken the mobile landscape by storm, Samsung unveiled yet another revolutionary form factor that took the mobile market by storm. Introducing the Galaxy Z Flip: a device that folded effortlessly in half and could stand upright on its own.

With the Galaxy Z Flip, Samsung revolutionised user interaction by introducing Hideaway Hinge. Much like a laptop, the hinge allowed users to open and position their phones at any angle. Users could securely fold, angle and position their devices, saying goodbye to shaky hands and hello to picture-perfect shots — whether they were snapping a hands-free selfie or capturing a moment with friends.

Also, Samsung released Flex mode, which automatically divided the screen into two when the device was folded. By collaborating with various partners, Samsung optimised this cutting-edge interface and enhanced usability. For example, in the camera app, users could preview the viewfinder on the top while adjusting the camera modes or lenses on the bottom. In addition, the phone supported Multi Window, enabling multitasking by simultaneously displaying different content on each screen.

Continuing the legacy of the Galaxy Z Flip, the debut of the Galaxy Z Flip3 took the series’ design and performance to new heights. The expanded Cover Screen was one of the phone’s most notable upgrades, now four times larger than its predecessor. Going beyond its traditional role of displaying the time and date, the device’s Cover Screen was maximised for both self-expression and productivity. Users could unlock their creativity by customising their Cover Screen with images or GIFs and conveniently view up to eight lines of notifications and messages. What’s more, Samsung Pay transformed Cover Screens into wallets — helping users make payments in one simple step.

The Galaxy Z Flip3 also boasted a variety of camera features that elevated the user’s photography experience to capture and share moments hands-free through Flex mode. With the addition of Auto Framing, the camera detected the location and number of people or objects within the frame and automatically adjusted the format accordingly for photos and videos. Suppose a photographer and the subject of a photo wanted to view the preview of a shot at the same time. In that case, all the user needed to do was tap the Dual Preview button at the top right-hand corner of the screen. Furthermore, users never missed a shot while striking a pose with the enhanced Quick Shot.

Not only could the Galaxy Z Flip3 fit nearly anywhere, but it also offered improved^[1] durability and water resistance^[2]. The lightweight exterior was crafted from Armor Aluminum, the strongest material used in Galaxy devices to date, and Corning® Gorilla® Glass Victus®, safeguarding users’ smartphones for any condition. A new protective film placed on the main display improved durability by 80% compared to the previous generation.

In 2022, Samsung released the Galaxy Z Flip4, complete with a host of practical features that effortlessly fit into daily routines. For instance, users could experience the convenience of the Flex mode panel^[3] which opened a touchpad that supports a range of gestures at the bottom of their screen. Similar to the cursor of a computer mouse, users could easily control various elements with a swipe of their finger — pausing, rewinding or playing videos without picking up the device. Another feature that increased productivity was the swipe gesture, optimised for multitasking. For example, if users swiped up with two fingers, the screen split into a top and bottom half to open a new app. With the swipe gesture, Galaxy made frequently used features, such as zooming in and out or turning pages, even faster and more convenient.

The Galaxy Z Flip4 also gave users more control than ever over their pictures. By simply pressing the side button twice, users embraced the Galaxy Z Flip4’s Quick Shot feature to capture moments and selfies without opening their phones. Now, they could even start a video on Quick Shot and easily transition to FlexCam without any interruptions. To capture the starry night sky, users could experience the all-new Nightography mode to take out-of-this-world shots, even in the dark — for bright, sharp photos with less image noise

The Galaxy Z Flip4 effortlessly blended high-performance capabilities with a personalised touch, truly reflecting its owner’s style. When the Bespoke Edition launched, there were new opportunities to express individuality — users could choose from a combination of five glass colours, including Yellow, White, Navy, Khaki and Red, and three frame colour options, including Silver, Gold and Black. Users could also enjoy the Galaxy Z Flip4 for even longer than the previous generation, thanks to its 400mAh larger battery^[4].

This year, Samsung released the Galaxy Z Flip5, delivering the most stylish, unique foldable experience yet. Built for self-expression and complete with an innovative design and customisable functions, the prominent feature is the upgraded Flex Window that is 3.78 times larger than its predecessor’s Cover Screen.

Thanks to the larger screen^[5], the Galaxy Z Flip5 offers more usability than ever before. With Flex Window, users can easily check and control Widgets, including the weather, stock market and music, without ever unfolding their phones. To see all Widgets at a glance, simply pinch the screen to activate the Multi Widget View function. The wider Cover Screen and fully accessible QWERTY keyboard make checking and responding to phone calls and messages even easier.

The new Flex Window provides the most versatile camera experience on a Samsung Galaxy smartphone to date. To snap a selfie with the rear camera, users can conveniently check their smile on the Flex Window before capturing stunning, hands-free photos from creative angles before correcting the colour and tone. The camera-stabilising Super Steady feature also ensures that users take smooth shots on the go. With improved Nightography capabilities to optimise photos in low lighting and digital 10X zoom, users can unleash their creativity anywhere, anytime and at any angle.

Now, there are even more ways to customise your Galaxy Z Flip5 inside and out. For instance, the new Flipsuit Case^[6] is equipped with a changeable NFC card, called Flipsuit Card so users can coordinate their Flex Window design and case design for even more personalisation options.
