The Galaxy S21 Ultra 5G delivers Samsung’s most advanced and intelligent pro-grade camera system, brightest and smartest display in a Galaxy and best Galaxy performance in a smartphone yet

LONDON, UK January 14, 2021Samsung Electronics Co., Ltd. has unveiled the Galaxy S21 Ultra 5G, a flagship for the bold that pushes the boundaries of what a smartphone can do. The S21 Ultra 5G pulls out all the stops for those who want Samsung’s best-of-the-best with our most advanced pro-grade camera system and our brightest, most intelligent display. It takes productivity and creativity up a notch by bringing the popular S Pen experience to the Galaxy S Series for the first time[1].



“The Galaxy S21 Ultra 5G raises the bar of what a smartphone can do, and with the new year we are bringing new innovation for Galaxy fans who want to stay one step ahead,” said Conor Pierce, Corporate Vice President for Samsung Electronics UK and Ireland.


“As we navigate through these challenging times, we know that connection is so important which is why we are delivering best-in-class features to our customers, including the largest screen in our S21 Series and the most powerful camera, packaged in a new premium design and powered by 5G.  What’s more, for the first time we are bringing our much-loved S Pen to the Galaxy S21 Ultra for users who want to take their productivity and creativity to a new level. For those who need the very best technology for streaming, gaming and capturing content, the Galaxy S21 Ultra 5G is the ultimate device”.


The Galaxy S21 Ultra 5G is the newest chapter in the Galaxy S Series’ decade-long legacy of delivering cutting-edge mobile experiences. It’s built for users who demand top-of-the-line technology to stay connected with the people and things that matter most. Galaxy S21 Ultra 5G joins the new Galaxy S Series of devices and takes every part of that S21 experience to the next level.


Incredible Innovation Housed in Unexpected Design

Galaxy S21 Series unveils a bold new style that sets it apart from other smartphones. It introduces an all-new, iconic Contour Cut Camera housing that seamlessly blends into the device’s metal frame for a sleek, yet striking, aesthetic. Galaxy S21 Ultra 5G available in Phantom Black and Phantom Silver and it is coated in a luxurious Deluxe Frosted Haze matte finish for an all-around sophisticated and timeless look. Galaxy S21 Ultra 5G also has three exclusive colourways – Phantom Titanium, Phantom Navy, and Phantom Brown and offers improved durability with Corning® Gorilla® Glass Victus™, the toughest Gorilla Glass yet.


Galaxy S21 Ultra 5G is the largest member of the Galaxy S21 Series with an epic 6.8-inch Dynamic AMOLED 2X display[2].  It is our most intelligent screen yet. For the first time, users no longer have to decide between the smoothness of a 120Hz refresh rate and a Quad HD+ display — on S21 Ultra 5G, you can choose both. The screen’s refresh rate adjusts to the content you’re viewing from 10Hz to 120Hz to ensure you enjoy the best image, whilst stretching your battery life even further. Compared with the Galaxy S20, S21 Ultra 5G offers a 25% brighter picture[3] at a 1,500nits of peak brightness, the brightest on a Galaxy smartphone. With a 50% improved contrast ratio[4], it delivers crystal-clear, immersive images, even when outside. And like the Galaxy S21 5G and S21+ 5G, Galaxy S21 Ultra 5G has Eye Comfort Shield[5] to help reduce eye fatigue.


Empowering, Best-in-Class Epic Camera Experience

Galaxy S21 Ultra 5G delivers with our most advanced pro-grade camera system, so that you can capture stunning, studio-quality photos in various lightings and settings, or shoot and edit videos with a toolbox of new AI-powered features that elevate every shot.


It has a quad rear camera (ultra-wide, wide and dual tele-lenses) that features a new 108MP pro sensor, from which you can capture 12 bit HDR photos with 64 times richer colour and more than three times wider dynamic range[6], allowing you to capture pro-grade content. For the first time on a Galaxy smartphone, you can shoot in 4K at 60fps across all lenses including front and rear four lenses, so you can shift to a different perspective with the same quality. Plus, with a 12-bit RAW file option, you won’t miss a single detail when editing photos.


When zooming in on S21 Ultra 5G, you don’t have to worry about sacrificing clarity. The Galaxy S21 Ultra 5G features 100x Space Zoom which is powered by Samsung’s first-ever Dual-tele lens system – one optical 3x and one optical 10x both equipped Dual Photodiode(2PD)– so you can capture crystal-clear shots no matter how far you are from the action.


Galaxy S21 Ultra 5G’s improved Bright Night sensor is Samsung’s biggest leap yet in low-light photography. With improved Night Mode, noise reduction and 12MP Nona-binning technology, you can capture challenging shots – like a dimly-lit room, or a landscape at night – quickly and with excellent quality.


Smart, Hyper-Fast Connections Across Devices

Galaxy S21 Ultra 5G continues Samsung’s legacy of delivering trailblazing technology like Ultra-wideband (UWB) and introduces new connectivity capabilities that will transform the way you interact with your devices.


Galaxy S21 Ultra 5G users expect the flagship smartphone experience to take creative expression and productivity to the next level. That’s why, for the first time on any S Series device, Samsung is bringing the fan favorite S Pen experience to the Galaxy S21 Ultra 5G with Wacom’s technology[7]. From drawing to note-taking to editing photos and signing documents, now you can unlock the power of the S Pen on the Galaxy S21 Ultra 5G. Use an existing S Pen from a Galaxy Note or Galaxy Tab or purchase an S Pen separately on its own or with a compatible case.


For better and faster connectivity, Galaxy S21 Ultra 5G is one of the first smartphones to support Wi-Fi 6E[8]. You will be able to enjoy more bandwidth and a faster internet connection[9], so you can stream and share content in the blink of an eye. With hyper-fast, ultra-low latency 5G[10], S21 Ultra 5G is built to provide fast video downloading, smooth video conferencing and streaming.


Thanks to the Ultra-wideband capabilities (UWB) embedded in Galaxy S21 Ultra 5G and S21+ 5G, you will be soon able to use your Galaxy S21 device to automatically unlock compatible car doors without pulling out your keys[11]. With the UWB-enabled Galaxy S21 Ultra 5G and Galaxy S21+ 5G, you can also use AR finder to visually guide you to lost items with SmartThings Find and drop virtual messages that let other Galaxy smartphone users know you need help searching for a lost item[12].


And with SmartThings on Android Auto™[13], you can also use your Galaxy S21 Series to control smart devices in your home, from your car. By connecting your Galaxy S21 Ultra 5G to your Android Auto compatible car, you can turn on your lights or even raise the temperature of your thermostat before you return home, all from your car. It offers faster speed[14], advanced computing and greater energy efficiency. And when the battery gets low, Galaxy S21 Ultra 5G can reach a 50% charge[15] in just 30 minutes[16].


We rely on our smartphones more than ever, which is why protecting sensitive information is more important than ever. Galaxy S21 5G is secured by Samsung Knox Vault, Samsung’s own proprietary chipset level (SoC) security platform. By adding tamper-resistant secure memory to our secure processor, Samsung Knox Vault enables S21 5G to add a new layer of protection.


Galaxy S21 5G also introduces a new tool to protect and monitor your privacy. You can safely remove location metadata from photos and videos before sharing. With Galaxy S21 5G’s all-new Private Share function, you can also control who gets access to the content you send, and how long it’s available[17].
