Samsung Galaxy S21 Ultra 5G (Snapdragon) Display review: Near-twin of Exynos version

The Samsung Galaxy S21 Ultra 5G (Snapdragon) has been selling in the U.S. and China (and a few other places) since January 2021 and is the near-identical twin of the S21 Ultra (Exynos) version sold in other parts of the world. Both share the same high-end specs, including the same quad-camera setup and stylus support; the only difference in hardware between the two versions is in the processors they use: the U.S./China-oriented model relies on the Qualcomm Snapdragon 888 chipset, while Samsung uses its own Exynos 2100 in the model sold elsewhere.

Because of their close similarities in performance, this review will mostly focus on the very few differences between the two versions in our comprehensive Display protocol testing.

Samsung Galaxy S22 Ultra (Snapdragon) 136 27. Samsung Galaxy S22 Ultra (Exynos) 134 32. Pros Well-balanced brightness and accurate colors lead to a satisfying experience when watching HD10 videos. Well-adapted luminance levels and high maximum brightness mean very good readability in most conditions.

The device has great smoothness when web browsing and in the gallery app. The device manages frame drops well when watching videos. Cons Color faithfulness deteriorates under very bright outdoor conditions, particularly under sunlight.

The device is inaccurate when zooming in the gallery app and does not correctly detect touches along its edges when playing video games.

Slightly dazzling in dark ambient conditions, and the BLF does not filter out enough blue light under any lighting condition. With almost entirely identical scores across all attributes, the Samsung Galaxy S21 Ultra 5G (Snapdragon) joins its Exynos twin in joint first place (as of this writing) in our DXOMARK Display rankings.

Readability Samsung Galaxy S21 Ultra 5G (Snapdragon) 74 76 Apple iPhone 13 Pro Max Best: Apple iPhone 13 Pro Max (76) Achieving an excellent score of 74, the Samsung Galaxy S21 Ultra 5G (Snapdragon) is currently in a three-way tie for first with Exynos version and the TCL 10 Pro. It has good readability at its default settings; however, the both S21 Ultra devices are somewhat dazzling in low-light conditions, which may make viewing a bit uncomfortable for some users. Indoors, the device’s brightness ensures that most content is easily readable, but darker tones lack detail.

Despite its high luminance outdoors, the S21 Ultra 5G (Snapdragon) lacks readability, especially for darker content. The Snapdragon-powered smartphone adapts smoothly to light transitions but the rendering changes abruptly when moving from sunlight to shade.

The Samsung Galaxy S21 Ultra 5G (Snapdragon) loses brightness when viewed in angle. As you can see in the array below, the Exynos version (second from left) is noticeably brighter: Brightness at a 45° angle, from left to right: Samsung Galaxy S21 Ultra 5G (Snapdragon), Samsung Galaxy S21 Ultra 5G (Exynos), Apple iPhone 12 Pro, Vivo X51 5G Photo credit: DXOMARK; for illustration only The objective measurements in the graph above confirm the perceptual results between the two Samsung devices.

Both devices offer excellent levels of brightness and color fidelity when watching HDR10 content. As for differences between the two models, as shown in the illustrative photo array below, the Exynos version’s rendering is just slightly more vivid and closer to the reference image rendering than the Snapdragon’s.

Video color, from left to right: Samsung Galaxy S21 Ultra 5G (Snapdragon), Samsung Galaxy S21 Ultra 5G (Exynos), Apple iPhone 12 Pro, Vivo X51 5G Photo credit: DXOMARK; for illustration only At 77 points apiece, both versions of the S21 Ultra 5G trail behind the class-leading Huawei P40 Pro at 87, with both showing some frame duplications and regular stuttering while playing video games, along with some hesitation in playback reactivity when rewinding or fast-forwarding videos. The Samsung devices’ lackluster results for motion are far overshadowed by their disappointing performance for touch, as both showed inaccuracies when using with fingers (though good with the S Pen stylus).

Further, although they were very smooth in the gallery app and when web browsing, there was a perceptible lack of fluidity when gaming.

Artifacts Samsung Galaxy S21 Ultra 5G (Snapdragon) 79 86 Apple iPhone 13 Pro Max Best: Apple iPhone 13 Pro Max (86) Artifacts is the only category in which the two S21 Ultra 5G models earned different scores, with the Snapdragon version bettering the Exynos by one point. Both devices have problems with ghost touches in landscape mode, and noticeable flicker in dark ambient viewing conditions. Flicker comparison This graph represents the frequencies of lighting variation; the highest peak gives the main flicker frequency.

That all said, the Snapdragon version of the Samsung Galaxy S21 Ultra 5G handles aliasing somewhat better than its Exynos twin, although neither device’s rendering would win it any plaudits from the gaming community: Samsung Galaxy S21 Ultra 5G (Snapdragon), aliasing closeup Samsung Galaxy S21 Ultra 5G (Exynos), aliasing closeup The Snapdragon and Exynos versions of the Samsung Galaxy S21 Ultra 5G are very similar, though the Snapdragon shows slightly better performance in handling artifacts. Overall, both show the same strengths and weaknesses: because of touch performance and aliasing, for example, neither model would be the first choice for serious gamers, but otherwise these latest Samsung twins come with a great display, especially for watching videos.

Samsung Galaxy S21 Ultra Review

In addition, US wireless carriers have revealed C-band 5G plans that the S21 Ultra is well positioned to take advantage of, and the phone is now widely available for less than its high list price. It’s a solid and premium-feeling phone with a unique (for the US) superzoom camera, a gorgeous screen, and future-forward network chops. The S21 Ultra sets the bar for Android performance in 2021 and its superzoom camera will lead you to look at the world in new ways. Samsung has three models in its 2021 flagship Galaxy S series: the small S21, the medium S21 Plus, and the large S21 Ultra.

The S21 Ultra is $999.99 at both Amazon and Best Buy at this writing, and Samsung has an intense trade-in game. That makes the S21 Ultra effectively less expensive than the iPhone 12 Pro Max ($1,099), which is rarely discounted.

My review unit is a solid matte block that resists fingerprints much better than last year’s glossy models. Slots and ports in general are, alas, going the way of the dodo; not enough people use them, and built-in memory has faster performance.

It hasn’t scratched after a few days of testing, an improvement over the Galaxy S20+ screen, which scuffed up quickly.

Samsung says that the screen is 25% brighter than the Galaxy S20 Ultra, at 1,500 nits maximum brightness.

You can set the screen resolution to 1080p or quad HD to save battery and increase game frame rates, but the option to manually switch between 60Hz and 120Hz refresh rates is now gone; instead, the display automatically changes from 10Hz up to 120Hz depending on what you’re looking at. The Ultra is the only member of the S21 family that works with Samsung’s S Pen, the active, pressure-sensitive stylus previously reserved for the Note series.

The S21 has the same super-low 9ms latency as the Galaxy Note 20 Ultra, updating the screen with its virtual ink at 120Hz. We’ve heard rumors that there may be no Galaxy Note phone this year because of a global processor shortage. As always, there are a bunch of different sub-models of the Galaxy S21, noted by a letter at the end of the product number. The U model has a single SIM slot, a Qualcomm Snapdragon processor, disabled e-SIM functionality, and all the appropriate bands for all US 5G networks, including millimeter wave and the upcoming C-band.

The PCMark and AIMark benchmarks appear to be broken on the S21 Ultra, delivering scores that are obviously far too low. For instance, the 888’s image signal processor lets the S21 Ultra combine its two telephoto cameras for much better 10x–30x zoom than last year, and a new Director’s Mode video feature lets you smoothly switch between cameras on the fly.

So even without reliable benchmark numbers to quantify speed and power, it’s clear that this is a big step up from last year’s models. The bloatware situation on the unlocked units isn’t bad at all, but you should expect the usual dozens of unwanted apps on carrier-locked models, especially on AT&T.

Samsung gets rid of its unloved Bixby Home screen and puts Google’s browser front and center. It’s worth pointing out that Samsung does its best to link to other Galaxy devices and Windows laptops, similar to how iPhones hook up to Macs.

On Windows laptops, you can answer texts, check notifications, or mirror your phone screen. You can also put the S21 in multi-windowed Dex mode for presentations on a big screen or use an additional keyboard and mouse.

Samsung’s home screen design still won’t be mistaken for Google’s, with its own colors, icons, and dialer. In our standard test, where we run a YouTube video with full screen brightness over Wi-Fi, we managed 11 hours and 20 minutes; that’s on par with other leading large phones. There’s a third-party app called Samsung Band Selector that might let you force your phone to use 4G, but it’s unsupported and could be disabled at any time. You can always opt to avoid the cable question altogether and get a Qi-compatible wireless charging pad. Verizon says it’ll cover 100 million people with C-band access by next March, which will likely triple the carrier’s 5G speeds. Standalone 5G, which eschews 4G, gives you lower latency and less chance of overloaded networks in crowded conditions, but you end up with slower overall speeds because you’re losing the add-on 4G components.

By forcing the phone into non-standalone mode using a field test screen, speeds rose to 258Mbps down and 69Mbps up on average, with 26ms latency. This will become especially relevant when you’re hooking your phone up to multi-gigabit home internet service, when and if that appears in the next few years.

Samsung’s phones used to work with older credit card swipe machines that didn’t have the Apple/Samsung Pay specs. I was very happy to see that Wi-Fi calling was finally available on my unlocked model on all three major US wireless carriers. The phone technically supports eSIM, but it’s been disabled on this model, and Samsung has shown no sign of intending to enable it. The S21 did much better at keeping different elements of a setup in focus, though its photos weren’t quite as sharp as those from the iPhone 12.

High-level zoom, which is really shaky on the S20 series, is now stabilized so it’s much easier to lock onto the part of the image you need. The big difference between this and the S20 generation is Night mode; the S21 has one, so you can finally take decent selfies in the dark. With good light, that front-facing camera is actually great, with more detail than the S20 Ultra, and better contrast than the iPhone 12. It was big and heavy, the list price was high, and carriers hadn’t released their C-band plans. And the more uses I find for the 10x zoom and games I play on the big, bright screen, the more I appreciate just how well this phone is put together. Samsung has some accessories to sell you, too: a watch, earbuds, and a smart tag locator.

The Note 20 comes with an S Pen and a microSD memory card slot, but the S21 Ultra is more future-facing as a long-term investment. The iPhone has nothing like the S21 Ultra’s superzoom, but it has somewhat better night performance and, for serious photographers, a much better ecosystem of third-party camera apps and integration with Mac computers. The OnePlus 9 Pro has speedy, elegant software and is also a great choice, but the S21 noses just ahead of it on radio performance and superzoom. Samsung Galaxy S21 Ultra 4.5 Editors’ Choice See It $1,049.97 at Amazon MSRP $1,199.99 Pros Beautiful design and solid build Equipped for next-gen C-band and Wi-Fi 6E connectivity Cons Heavy The Bottom Line 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.
