(6,946 reviews)

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 chipset, strongest glass, 5G and an all-day battery, Ultra easily lives up to its name. Designed to scratch less and protect both front and back, this is the toughest Gorilla Glass in a Galaxy smartphone. 8K Video is the highest resolution video available in a 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. 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. The 108-megapixel camera captures so much detail, you can pinch in and reveal even more shots within. This camera quality expresses rich color data for true-to-life details and hues that don't get washed out in the sun. Galaxy's first 5nm processor packs epic power and speed. This outstanding upgrade means faster processing and more intelligence in every aspect of Galaxy S21 Ultra 5G.
