Samsung Galaxy S21 Ultra review: 2021’s true S Series phone, and the best yet


There may be three new Galaxy S Series phones this year, but only one really fulfills the criteria we expect from the range, and that's the Galaxy S21 Ultra.

Highly capable, versatile camera ; Beautiful AMOLED screen ; Elegant new design ; Long battery life ; Latest software from Google and Samsung ; Price is down from last year

Shaky Wi-Fi connectivity ; Intermittent charging problems ; Top-heavy design affects balance ; No MicroSD card slot

Samsung Galaxy S21 Ultra Review


Beautiful design and solid build ; Excellent photo quality at up to 10x zoom ; Equipped for next-gen C-band and Wi-Fi 6E connectivity


The Galaxy S21 Ultra delivers a high-quality superzoom camera that truly works, supports Samsung's excellent S Pen, and sets the bar for smartphone features in 2021.

Samsung Galaxy S21 Ultra review: All of Android for somewhat less


The Samsung Galaxy S21 Ultra is less expensive than the S20 Ultra, and it's still Samsung's best and most full-featured phone to date. It is very big, though.

Gorgeous screen and overall design ; Excellent camera with killer telephoto abilities ; Great battery and performance

Big and heavy ; No MicroSD card slot

For most buyers, the Galaxy S21 Ultra will be too much phone for too much money. Like the iPhone 12 Pro Max, it’s very big and heavy, and it will set you back a bundle of dough. If you’re the least bit cautious about what your spend, this isn’t the...

Samsung Galaxy S21 Ultra review: Small changes yield big results


The Samsung Galaxy S21 Ultra showcases the best Android has to offer

Excellent performance ; Large and vivid 120Hz adaptive display ; Versatile and impressive cameras ; Reliable software updates ; S Pen support

Slightly disappointing battery life ; No charger in the box

The Samsung Galaxy S21 Ultra may not be the peak of Android performance this year, but it is perhaps the most well-rounded Android flagship with an unbeatable camera experience.

The Samsung Galaxy S21 Ultra & S21 Review: The Near Perfect and The Different


After many years of ever-increasing flagship device prices, this year Samsung is taking a quite different approach with the new Galaxy S21 series – not only stopping the price increases, but actually reducing this year's flagship line-up prices...

Investigating The Galaxy S21 Ultra New OLED Emitter: Huge Efficiency Improvements


This generation of Samsung flagship devices in the Galaxy S21 line-up is quite different to that of past years, as Samsung has opted to create a much more uneven device line-up between the “standard” Galaxy S21, S21+ and the larger, more feature-packed...

Samsung Galaxy S21 Ultra Review – Lower price brings tougher decisions


Samsung's Galaxy S21 Ultra is more affordable than last year's flagship, has more cameras, and adds an S Pen: on paper, at least, what's not to love? Setting the bar for smartphon…

Fantastic 120Hz display makes no resolution compromise ; 108MP camera is capable of great photos ; More affordable than last year's flagship phone ; Potent performance and long battery life ; S Pen functionality is a welcome addition from Galaxy Note

No microSD, no Samsung Pay MST, and slower charging than the S20 Ultra ; 100x Space Zoom still feels like a gimmick ; S Pen implementation feels half-hearted

Samsung Galaxy S21 Ultra review, zooming in


Check out Samsung's Galaxy S21 Ultra flagship specs, performance, camera and battery life review, what's in two zooms?

The longest, cleanest zoom on a phone, and most versatile camera set; The best battery life in its class; Brightest display with the most granular adaptive refresh rate; Stylish Contour Cut design and richer variety of colors; Unique 12-bit color RAW...

Still big and bulky to carry and use, especially with an S Pen case on; $1200 gets you just 128GB, no charger, earbuds, or memory card slot; The new ultrasonic finger scanner is still comparatively slow; Softness in the main camera sample edges
