if you know about photograph, sure will choose camera A in blind test. see image result from camera A, similiar to canon eos digital camera. but camera B is similiar to cheap digital camera with too much sharpening.

TL;DR: Ideal phone is able to do the 808 level output while also saving 2nd image with pre-processing to get more "easily consumed output". (preferably without the artifacts. ie. save one raw file and another file that does corrections based on user sharpness etc preference using a user-profile/template)
"Really GSMARENA? More people chose the Huawei P20 Pro ('B')? "
This comment probably won't get past moderation but it's important with hardware gadget and gaming review sites to consider where does the site get most of its funding or perhaps in this case, what corporations pay the bills of the people voting.
I do like to have quick pre-processed photos (for certain purposes), and P20 Pro photos clearly won in terms of how easily you could make out the details in the photos. However you have to also consider the people who would want a "camera phone" vs a "phone with a camera". The 1020/808 belong in the "camera phone" category and P20 Pro doesn't. Camera phone should be fit for replacing a dedicated camera. This means the output should have good depth/"3D-ness".
It would have been more fair to get as raw output as possible from each phone at 40 MP and then resize to say 20 MP. Then make dedicated crop shots that have the average RGB normalized to a cluster of pixels in the crop. Or in other words, have the crops roughly equally lit to make it easier to evaluate whether there's difference in detail.
But this isn't really needed now. The link previously posted* shows a very good comparison of what I mean by "camera phone" vs "phone with a camera". The 808 output looks much closer to DSLR output, which is what the buyer is trying to replace with "camera phone", to avoid carrying two devices while getting "good enough for person into photography"-output. ( * http://www.allaboutsymbian.com/features/item/22923_By_popular_demand_Nokia_808_Pu.php )
The way to compare the camera performance is to look at the "3D-ness" or "depth" perceivable, while normalizing to weight/size. When looking at the images try to ignore the differences in sharpness, contrast and such which you can fix with algorithms. (it would be preferable if the camera/phone would have this A-B slider between raw and processed image built into the viewing software, so it saves raw and then separately saves processed photo. To make this very fast the phones should have Optane DIMM instead of NAND.)
It's much MUCH harder to add depth after the fact. In fact digital processing practically always reduces the perceivable depth because the algorithms don't even know about it. If you happen to be familiar audio processing, the same thing applies there. The more digital effects you apply, the more processing artifacts you introduce (because schools teach DSP algorithms that are simplistic) and if you had a high quality source, depth in the source would be lost (eg. compare binaural (real stereo ambience capture) recordings to some DSP effected "fake-surround" recordings...).
When done this way, you find that the most expensive systems tend to be best (Hasselblad and so forth) as they have largest optics etc.
So now you know why the P20 Pro lost this comparison without even having to look at the images: To make a better camera than 1020 or 808, it needs to be same physical size optics/sensor at least. Then use custom FPGA with Optane DIMM to make it as fast as the rest of the phones.

MG7, 09 Apr 2018P20 pro will win against 5 year old tech. But nokia was much ahead of its time. In comparison ... moreBut it have a bigger sensor (1/1.5"), moreover the P20 noise reduction are so agressive, do you even see its low light sample are reminded me with the worst Mi 5.
Anonymous, 09 Apr 2018Huawei should drop some of that processing and the pictures would look better. Like somebody m... moreThey can't, they bundled 4 of the same color filter together to make downsampling to 10MP easier, therefore color resolution is greatly reduced and what you're seeing is intense interpolation and then sharpening. You could see from Gsmarena's lab samples that the 40MP sensor doesn't even yield as much resolution under *optimal lighting* as a good 12MP like the S9+ or the Pixel2XL, and it's much worse under low lighting.
AnonD-1825, 11 Apr 2018What are you talking about? It already lost by clear margin.The artifacts introduced by the "quad-bayer" makes post-processing impossible, also the CA across the frame is hugely problematic. The P20 only wins resized to FHD-2K, when you retain the resolution you're supposed to look into it, and there it loses with fake sharpening and artifacts..
Anonymous, 17 Apr 2018Pay particular attention to sponge Bob and the dollar bill and the map and view on a desktop P... moreIndeed, it's between the S9+ and Pixel2XL, the XZ2 has too much sharpening, and what's funny is the P20Pro loses in detail to all the above three in 40MP mode, even at base ISO. The 40MP mode is really good for nothing.
Nito Niwatori, 21 Apr 2018Phone B is good for normal user I guess it got nice WB but over sharpen and lost huge detail ... moreYou also see artifacts in the snail sample, the way the paint's rendered on the P20Pro, it's not how the snail is painted, that's also due to the color filter layout. You could see a softer render of how the paint actually is from the Lumia.
Interesting to see next Huawei with same 40 mpix sensor.
It seems that even Nokia 808 gives a run for its money too. Even with zoom capability.
Dunno why people like the P20 Pro better, sure it renders details more clearer but the color reproduction is so unnatural compared to the 1020. I think I'd rather go for the 1020 in terms of camera performance.
Phone B is good for normal user I guess it got nice WB but over sharpen and lost huge detail
(Well we all feel that Phone A is blurry yes it is ...)
Until the last picture we all see kind of moire in building ... (I don't know why they didn't reduce it both CA and Moire in those jpg ? only just sharpen it)
Hope you can do another test base on " RAW " from both phone ... >___
