Camera - Low Light Evaluation
Low-light photography of the new S21 series devices should be relatively uneventful. Both the Ultra and the regular models don’t have any superior light gathering abilities compared to their predecessors, so in general the differences between the generations should solely lie in terms of software algorithm updates – if there’s actually any.

In the first scenario, we see the S21 phones showcase excellent results in their respective night modes. There are small differences when it comes to colour temperature and blacks, where the new Ultra phones don’t seem to be as fine-tuned as the Note20 Ultra or the baseline S21, but generally fall in amongst the best performing phones.

[ Mi 10 Pro - ] [ Pixel 5 - ]
[ X-T30 ( ) ]
This scene really wasn’t kind to the new Ultras, as the Note20 Ultra produced significantly better and more realistic shots in all capture modes. We’re again seeing some of Samsung’s stark software inconsistencies at play.

The S21 Ultra issues continue here as well, the Snapdragon unit is just far blurrier than the Exynos and the Note20 Ultra, while the Exynos’ colour temperature is too cool and overcompensates the orange sodium lamps.

In this scene I was curious to see the dynamic range the phones would be able to retain in night mode – those lamps actually weren’t all that bright at all, it’s just that the rest of the scene was just very dim.
The Samsung phones didn’t improve all that much generationally, and still lag behind the leader in low-light dynamic range, Huawei.

[ X-T30 ( ) ]
This scene is easier to analyse, as essentially, we’re seeing little to no differences with the new S21 series phones bar a bit of colour temperature variations.
[ S21U(S) ] [ S21U(E) ]
[ S21(E) ] [ S20+(E) ]

[ Mate40 Pro - ] [ Mi 11 ]
[ Mi 10 Pro ] [ Pixel 5 ]
[ X-T30 ( ) ]
Going into lower light situations, we’re seeing larger differences. The S21 Ultra Snapdragon falls flat on its face here in terms of night mode processing as everything is a blurry mess. The Exynos variant fares significantly better, and is actually along with the Exynos S21 the best results of any phones night modes, going as far as clearly depicting the Orion and Pleiades constellations in the background sky.
[ S21U(S) ] [ S21U(E) ][ S21(E) ] [ S20+(E) ] [ Note20U(S) ]

[ X-T30 ( ) ]
Lastly, just for fun and because I had an unusually clear night sky, I tried out pointing the phones at the sky to see what happens. These are all handheld shots without a tripod. Sadly enough, the Ultra phones lagged behind the regular S20 and S21, and far behind the Huawei Mate 40 Pro.
Low-light verdict: Pretty much the same
Low-light photography on the S21 series, hasn’t really changed all that much from the S20 series. Frankly speaking, in some scenarios, it might be even worse due to the immature software, particularly on the Snapdragon S21 Ultra. We didn’t really expect any improvements this generation as essentially, it’s all pretty much the same hardware, but I was still disappointed to see that the software side of things is still handicapping Samsung from achieving better results.
The same conclusion applies here as on the daylight shots, in that we don’t really have a conclusion. The results are too inconsistent, and I’ve already had two newer firmware updates I would need to re-test things on. The picture quality will undoubtedly improve, but it’s getting quite tiring to wait months for Samsung to sort things out.

Can you comment about black clipping at minimum brightness? Back when you were testing s10 you would show minimum brightness graphs i really miss those they were important for me.Andrei Frumusanu - Monday, February 22, 2021 - link
Black clipping on the S21U occurs at 7% levels at minimum brightness after which it has accurate gamma, it's a bit better than the S10 but still not great. On the S21 it clips at 7% as well, but has garbage high gamma up until around 13% after which it is fine. I'll add the graphs tomorrow.Psyside - Monday, February 22, 2021 - link
Upon further inspecting of all photos, i have noticed the bad blurry, grain and out of focus early firmware characteristic, i can confirm that nothing of that edge blurriness, lack of sharpness and softness is not present in AUB9. The 10x zoom shots are stunning, and the night shots without night mode are also very much improved.Andrei Frumusanu - Monday, February 22, 2021 - link
I say as much in the review that there are firmware updates. Unfortunately I can't delay testing arbitrarily in hope that Samsung updates their camera software, nor am I going to redo the testing for a given review.If Samsung has improved the camera, that's great, and I'll cover that in the next round-up.

Those camera jumps are UGLY AS SIN. good thing we don’t put a bigger battery in and flatten the bottom of the phone!Chaser - Monday, February 22, 2021 - link
While I respect Anandtech, a majority of professional (smartphone only) reviewers disagree with your assessment of the Ultra 21 and in my experience I can second their very positive experiences with the camera and the rest of the phone's refinements. Especially compared to the S20 Ultra.Psyside - Monday, February 22, 2021 - link
Andrei stated that most if not all shots are on early firmware, the camera was quite bad at launch.Psyside - Monday, February 22, 2021 - link
He will redo the comparison in future articles
