Product Information

Epic.
In every way

Introducing Galaxy S21 Ultra 5G. Designed with a unique contour-cut camera to create a revolution in photography — letting you capture cinematic 8K video and snap epic stills, all in one go. And with Galaxy's fastest chip, strongest glass, 5G and a powerful battery, Ultra easily lives up to its name.

Introducing a bold new camera design in a category of its own. It's ultra-sized with a contour-cut camera that seamlessly houses cutting-edge lenses.

GORILLA GLASS VICTUS™
Our toughest glass

Designed to scratch less and protect both front and back, this is the toughest Gorilla Glass ever in a Galaxy smartphone.

Take epic portraits right out of 8K video
8K Video is the highest resolution video available in a Galaxy smartphone — that's four times as many pixels as 4K. Record in 8K 24fps and get crisp footage that looks better than the cinema, then upload and watch right on YouTube.

And with 8K Video Snap, you can pull an album of epic high-resolution photos straight from 8K video. So you don't have to choose between shooting video or stills.

S Pen compatibility means you can finesse and fine-tune while editing your videos down to the last frame, with precision that your finger simply can't touch.

Turn on Super Steady and Galaxy S21 Ultra 5G shoots like an action cam. AI stabilisation eliminates the bumps, delivering gimbal-smooth video when you're on the move.

Super Smooth 60fps Video delivers a dynamic frame rate for super-smooth video even in low light. It automatically adjusts the fps, so your video stays polished as you go from day to dusk.

Crop, crop and crop again
The 108-megapixel camera captures so much detail, you can pinch in and reveal even more shots within. This camera quality expresses rich colour data for true-to-life details and hues — that don't get washed out in the sun.

100X SPACE ZOOM
One small tap for you, one giant leap for zoom

The breakthrough Dual Zoom system now zooms in faster, smoother and sharper than any zoom in the Galaxy series. And when paired with the all-new Zoom Lock, shots are more stable than ever.

Portraits get a face lift. Studio-like Portrait mode is now enhanced by AI to deliver the ideal lighting in your photos — analysing faces, lighting angles and direction and mapping depth of field.

The Bright Night sensor is our biggest leap in low light photography, capturing bright, vivid colours in the dark of night. Shoot clear images with more speed and significantly less noise, while also controlling exposure time.

SECURITY
Lock it up

Galaxy S21 Ultra 5G delivers the highest level of security certification — with Samsung Knox securing your phone from the chip up and Knox Vault encrypting your biometric authentication data. And the larger Ultrasonic Fingerprint sensor improves latency and dry finger recognition for fast, accurate unlocking.

INTELLIGENT BATTERY
Power to keep up with you

Galaxy S21 Ultra 5G's Intelligent Battery outlasts the day — even on 5G. Maxing out at a massive 5000mAh, it combines with the new power-efficient display and processor to live on beyond the 24-hour mark.

Big Screen Chat with Google Duo is a new way to catch up with friend groups and loved ones. Compatible across devices, it's easy to stay close to those who matter with just a tap

Motion Mirror lets you project your phone to your TV, so you can follow a workout routine. As you keep in step, you'll see your moves right alongside your instructor.

S Pen is precision at your fingertips
That's right, it's the first S Pen for the Galaxy S series — rewriting the rules for mobile by delivering a familiar pen on paper feeling.
