They only show the jpgs, which have nearly nothing to do with the raw data of the sensor. Overexposure, jpg dynamic range, tone mapping, colors, noise reduction, etc mainly depend on the algorithms of the manufacturer. Even the autofocus doesn't only depend on the sensor. Furthermore, a large sensor doesn't capture more light per time than a tiny sensor, if the effective diameter of the lens is the same at the same field of view. An iPhone 12 Pro Max captures approximately the same amount of light per time as the Panasonic Cm1. The Vivo X60 Pro Plus main camera captures more light per time than a Canon Aps-c camera + kit lens.

abc-to-xyz, 25 Mar 2021Bayer sucks for quick processing which effects both video a... moreSimple RGB or even RYYB with larger sensor pixel size behind instead of guess-working, something what S20/S20+/S21/S21+/iPhones been doing with their main camera (have not seen RYYB implementation within this setup though, not sure if predicting yellow accurately would be possible this way).
and QBF basically combines smaller pixels to emulate larger pixels in darker scenes, which is not the best way to go since it is hard to know which bit of picture requires what sort of combination. Samsung/Omnivision tried to fix this using Tetracells/4-cell but it is still not as good as natural large pixels. Also the fact that processing effects quality of dynamic content such as moving photos and videos regardless of how good Memory/ISP/SoC be.

I mean what other CFA design do you suggest then?

This doesn't really make any sense to me, could you elaborate?

Anonymous, 24 Mar 2021Curved sensor is just gonna deal better with distortion and... moreIt's said that with a curved sensor, because of the curve, electrons are less likely to interfere with neighbouring pixels hence lower noise, secondly because of simpler lens designs, it's possible to have wider apertures.
https://www.dpreview.com/news/5645755619/sony-a7r-iii-pixel-shift-lifts-a-veil-off-your-landscapes.amp
Have a comparison between the pixel shift multi shot on the a7r iii which takes 4 shifts to cancel the bayer pattern, the pixel shift is much sharper and detailed especially in areas of colour such as the brick walls. We can see the same thing on test charts.
Bayer is inherently flawed, it's just the best we have.

There is nothing wrong with Bayer. If you want the best results your phone can give, you need to learn how to use Pro modes.
Look at the review of Oppo. Many photos using very high ISO.
Lower ISO would easily gives way better results from same phone.
And You can correct colours if phone do not adjust correctly.
Two options. You can make your phone take photos the way you want or let it take the way it wants at the risk you dont get results you expect.
My phone is old and does not have OIS.
I can force ISO50/100 and have very decent photo or I can let it on auto at risk it decides to use ISO800/1600 or more and unusable photo.

Few choose neutral White balance, other choose bit colder while other go for vibrant/warm.
Of course, if cmos has different pattern like yellow, cyan, magenta the colours change.

Nick Tegrataker, 24 Mar 2021QB sensors suffer from artifacts and speckly noises only wh... moreI'll be honest. I'm making claims based on images I saw myself, which are mostly JPG's, admittedly quite a non scientific way to judge. I compared a K20 Pro with LG G8x, latter's native 12MP being better in my opinion.
And none of these seem any match for a traditional 1.75um sensor found in 10 year old Nokia N8... whether its details or just plain colour quality. I'm not talking boosted saturation, just plain colour quality in extreme light sources like sunlight or so.
In the end, even if the 48MP to 12MP images are slightly better, I fail to see the big big benefit it was supposed to give.
It just seems that instead of this, an expensive glass lens with traditional sensor might have been better investment... What do you think?

These large sensor phone really need a multi aperture solution like Samsung had on the S10 although that used a much smaller sensor, whereas the pixel has roughly a f11 equivalent lens, this will have a roughly f5.6 equipment lens resulting in a much shallower depth of field. In bright daylight, we should have the option to stop down to get more of the frame in focus.
My second concern about the large sensor is the focal length which keeps getting wider, the OnePlus 9 pro has a focal length of 23mm on the main camera, the Samsung s21u has moved to 24mm from 26mm, multiple generations so the S5 had a focal length of 31mm. There is so much perspective distortion on the photos by modern phones, but dxomark does not measure that so manufacturers don't bother.

I do wish more r&d were put towards an alternative to Bayer but megapixels sell and manufacturers have just increased megapixel counts and used other techniques to try and circumvent the flaws of Bayer.
As to what else can be done at the moment to improve smartphones photography, I'd say curved sensors, but I don't see 3 chip solutions anytime soon.

Anonymous, 24 Mar 2021in binned mode, there shouldn't be any artifacts beyon... moreYes, that I'm clear about. With 4 sub-pixels of the same colour, hardly anything can be expected in full resolution mode.
What I'm still not clear with is, what did we achieve ultimately even at 12MP?
The achieved photos are not notably better in all aspects, maybe 1 gained here, 2 lost there.
And I still like the natural colour of traditional sensors.
In fact, what I suspect is, with the gaps between the 4 sub pixels, it might actually cause loss of light.

jeez...
why are there so many verified accounts with tons of upvotes and comment counts on their names in this comment section?
i thought yall cared about budget phones too, not just flagships.
gsmarena's comment sections are ridiculous.

Curiosity ( ones with 4:3 form)
1/4" = 8mm2
1/3" = 17mm2
1/2.6" = 24mm2
1/2.3" = 29mm2
1/1.7" = 43mm2
1/1.5" = 58mm2
1/1.3" = 72mm2
1/1.2" = 85mm2
1" = 122mm2
Yes, camera of samsung is 3x larger than Pixel / iphone non-max

LG had like a powerpoint to show it, one phone had glass lenses, i think v30.
But glass lenses would cost more and add some weight.
Solution is monochrome and wrgb sensors.
Samsung is gonna bring many wrgb in 2021/22.
I would easily trade UWA to have wide monochrome.
To me this would fit well:
- 27mm rgb + 27mm mono : both 1/1.4" , with f2.2 ( i do not like blur seen on closeups photos)
