Samsung Galaxy S21 Ultra 5G review

This year, the Galaxy S21 series came earlier than expected, and it brought a slew of changes. The Galaxy S21 and S21+ now feature lower-res OLEDs, no...

The best OLED screen, 1000+nits, 1440p, 120Hz, HDR10+, S-Pen.

Somewhat bulky and slippery.

If you are after the best and newest phone on the market - look no further - that's the Galaxy S21 Ultra. It has its issues, but the overwhelmingly good features elsewhere and a patch or two will make up for everything. Samsung is definitely off to a...

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

Heavy

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: the real deal

It's finally, truly "Ultra."

Excellent camera system ; Beautiful screen with high refresh rate ; Great battery life

Ads in Samsung software ; No expandable storage ; Bixby

The Samsung Galaxy S21 Ultra is a huge, powerful Android phone with no fewer than five cameras. The main 108-megapixel sensor is the best Samsung has ever shipped, the Snapdragon 888 is fast, and the battery lasts a long time.

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
