Charging sucks on the ultra. Without the wall adapter it charges really slow (takes 5-6hrs to fully charge from 5%)... Its all hype

"The primary camera uses Samsung's latest 108MP ISOCELL HM3 1/1.33" sensor with 12,000 x 9,000 pixel grid and 0.8µm pitch. It has a Nona-pixel Bayer filter pattern that allows for 9-to-1 pixel binning, so the effective pixel size becomes 2.4µmm and the resolution 12 MP." - can somebody explain the mathematics behind 9x0.8 = 2.4?

[deleted post]He's right though. No need to mock a person who is simply making a logical argument based on facts.

Moreover they stated in 2019 that the new ISP on Kirin 990 supported it, so it's borderline impossible to assume that Kirin 9000 doesn't use the same algorithms.
Now, looking back at the GSMA's low light photo comparison chart, Mate keeps the noise level lower in low frequency areas while maintaining comparable or even slightly higher amount of texture details as S21U (and Mate achieves this despite using the centre 9MP crop of its sensor, vs S21U's full 12MP).
I'm sorry tell you this, but I don't see what you're seeing at all.

Just seen demo piece at store.
Its too huge to hold in one hand and heavy.
I would still prefer size of normal s21.
Anyone bought normal s21 give feedback about :
1) heating issue
2) battery life
3) camera review

" or a ruggedly handsome attempt gone sideways and looking like a project done in haste instead."
What bias planet are you from? The freedom refresh is one of the only upgrades here. And if this looks that bad then nothing in the market looks that great.

new leaks of exynos amd where graphics scores are doubling the IPhone 12 a14 which could well be true as exynos been marketing it significantly looks like last chance redeem them self's
this is good as it creates more competition where everything improve much faster like old exynos vs snapdragon from s2 3 4 5

Another huge bug found. If you accidentally slide down the screen in games, the notifications bar will be stock on top of the game. Only way to remove it, is closing the game totally, and open it all over again. Navigation bar goes away, but not the notifications bar.
Yet another thing you didn't mention, because Samsung didn't allow you.

I've just received the silver 512gb with 16gb Ram version.
I've rooted it , it's overclocked CPU, and upgrade the GPU to 1300mhz.
Omg, it's 2 times faster than standard. The graphics are on 70fps than standard 60fps rubbish.
The phone is very fast zippy than standard. The phone reached 45 celcuis hot, doesn't or don't give a rat's about being even 50 celcuis. Doesn't throttle. CPU governor is always on extreme, so CPU Idols at 80% all the time. The battery drain is 30% more than standard. I keep a 3000mah power bank with me .
After rooting, no one or anyone would go back too P O S standard.
In extreme version this is 2 years ahead like having S23

Anonymous, 27 Jan 2021Go purchase a 50$ wired and wireless earphones and tell me ... moreYou miss the point. People just don't compare wireless vs wired headphone at the same price point. People just buy wireless because it's convenient and cool. I have some friends that cannot feel the difference between my 300$ audiophile headphone to 20$ headphone, or 200$ iem to stock samsung iem. Anyway, price dont justify the quality, most wireless headphones are average compare to headphone audiophile grade on lower price.

TheLastOracle, 28 Jan 2021BM3D technique is basically a image denoising algorithm, an... moreHuawei clearly stated during the Kirin 990 announcement that its ISP uses BM3D NR to handle noise in still images, and if you do a bit of research you'll find out that this very algorithm is indeed developed by University of Tampere and Huawei - which explains why no smartphone/camera manufactures but only they managed to implement it on their products. Have Qualcomm or Samsung stated anywhere that they use the same algorithm on their flagship SoCs? If you know then please kindly quote.
It's also worth mentioning that BM3D NR has some interesting characteristics - Noises in low frequency areas of an image are swept away whereas textures and lines are selectively preserved instead of turned into an oilpainting - which Mate exactly shows in its image. On the other hand, S21U still leaves a bit of noise in smooth/immacurate sections in the frame while losing some details (See the fish on the lower right corner). I should ask, where is your assumption that S21U uses BM3D NR coming from?
