What does the Samsung Galaxy S21 Ultra have to offer?

samsung galaxy s21 ultra in hand

‘The phone that’s epic in every way’ – that’s how Samsung bills the Galaxy S21. And it’s a description that’s well merited. This is a smartphone that really packs a punch.

The S21 Ultra edition is Samsung’s top-of-the-range Galaxy S smartphone for 2021. And that’s principally apparent in its staggering four-lens camera, which is home to one of the most powerful zooms we’ve seen on a smartphone and consistently serves up outstanding photos.

Elsewhere, the Ultra features a 6.8-inch screen that’s one of the largest and brightest of any Samsung phone, as well as a powerful 5,000mAh battery and 5G support. So you’ll get a high-grade mobile internet experience to match the S21’s Ultra’s high-end specs.

Design and processor

Like the S20 Ultra, the S21 Ultra 5G comes with a big, curved display. It has a pleasing matte finish and a contour-cut camera which seamlessly houses its five lenses. The in-screen fingerprint sensor is faster to unlock your phone. And it’s larger than previous models too, so easier to hit.

The S21 series all have much faster processors than 2020’s S20 range, as well as 5G, meaning more power and faster speeds.

Screen

The S21 Ultra 5G comes with a 6.8-inch screen, smaller than its predecessor and more manageable in the hand. Its curved Gorilla Glass on front and back is the toughest yet, meaning minimal damage if dropped.

The display can reach up to 1,500 nits, so it gets incredibly bright - this is particularly helpful when your phone is in direct sunlight.

Camera

The S21 Ultra 5G boasts an impressive five cameras in total. Its quad rear camera (ultra-wide, wide and dual tele-lenses) features an upgraded 108-megapixel pro sensor, the highest resolution currently possible in a smartphone.

The Dual-tele lens (3x and 10x optical zoom) powers a massive 100x Space Zoom and the new Zoom lock feature will keep things steadier as you close in on the action. A faster Bright Night sensor means the Ultra performs well in low light too.

With 8K video recording and video snap, along with the new ‘Director’s View’ which lets you use the front and back cameras at the same time, you’ll be shooting home videos like never before.

S Pen Compatibility

For the first time ever, a Galaxy S device supports the S pen - great for general productivity and for those with a creative spark.

It means you can finesse and fine-tune while editing your videos down to the last frame, as well as sketch and take notes. Bear in mind that the S Pen is sold separately, as is its protective case.
