That there is an excellent lowlight shot you linked:
Yes there is sharpening algorithm there, but that is ISO 160, and same is applied at ISO 50 at 1/1s shot.
But on those higher ISO ones I really dont know how you can call it on sharpening, all is equally fine tuned noise.
Croma on that other I really dont see, maybe on a desktop monitor it would be discernable...
Pixel with OIS also keeps the noise for detail, doesnt overreduce it to loose detail, and has much obvious noise, sharpening artefacts, and chroma noise you mention. that I just dont see on Xperias high ISO shot:
And yet, Pixel is considered a top lowlight shooter.
P.S. Before anyone comments of extra brightness on Pixel, nearest street light is on on that shot, on Xperia not.

Sky is having a purple tint on XZ2 and I find it much more "artificial" than what Huawei and Samsung do with the colour of the sky. And you should also remember that XZ2 also boosts contrast significantly to hide noises under low-light condition.
Kinda funny though, because for last couple of years Galaxy phones had been known for oversaturated and contrasty photos, but now it's completely opposite and produce one of more accurate-looking photos at least in terms of colours.
Tann Hauser, 16 Mar 2018I am sorry, but clearly you misunderstand the sharpening artefacts.
In those pictures you lin... moreAgain, as I said before, if they are really just "noises", then they shouldn't exhibit any sort of splotchy, uneven zigzag patterns, which unfortunately shows up on (pretty much all) XZ2's photos. They contain a lot of noises, yes, but also a huge amount of sharpening artifacts. You would know this if you had edited RAW image on a smartphone even once (which probably you hadn't, since Sony phones do not support RAW image capturing) - this is not what the pure luminance noise looks like.
And as for the part where you said that oversharpening causes light sauces to form multiple layers instead of having smooth transition, that shows up in XZ2's photos as well. It's just that the noise level is so high that you cannot clearly see the "layers" of light, but if you look closely you can tell there are some uneven transition in the colour of light from light sources. Here's another photo (this one is taken with long-exposure) for you so that you can check some obvious sharpening halo around the light sources far away. This one exhibits strong patterns of sharpening on the left side of the image.
"And colour noise? You mean chroma noise? It is nonexistant"
Nope, I'm actually talking about colour/chroma noise.
This photo contains a lot of colour noises (red and green dots) across the whole image. It's suppressed and reduced so it's not something you can tell unless you zoom in, but it is definitely there once you start getting closer.

In those pictures you linked I clearly see the noise but not oversharpening.
Oversharpening for ex, is present here:
....around every light source there can be seen layers, not smooth transition, that is oversharpening artefact.
And colour noise? You mean chroma noise? It is nonexistant, I can see only high ISO noise around cars and lights.
Maybe you are thinking at colour fringing?
Both have those, in same areas.

On the other hand, Mate 10 Pro boost the contrast but this will causing certain scene and object look unnaturally this causing the image looks artificial. iphone wipe the image looks more cozy and still punchy color but doesn't like Samsung.This time XZ2 much better overall because don't wipe details don't artificial with much colors show, it much close to reality too.

And I'm pretty sure even with brighter (hence softer) lens, sheer resolution count of the high-res sensor which Sony uses can make up for it by a large margin.

"Too much noise reduction as some other do it, looses detail and sharpness, and produces less quality image"
The most of "noise" you're seeing on XZ2's nighttime photos are caused by oversharpening. Take a look at those photos, for example.
Instead of being finely grained, noises are more like blobs and you can see a lot of sharpening artifacts around cars and roads in the first pic.
The second picture has another problem - You can clearly tell that the whole thing is covered by quite a lot of colour noise, which all recent flagship smartphones handle perfectly. They are especially visible around moving objects such as front lights of cars.
"And Daylight ones are top, dont even have to discuss those"
With tons of oversharpening artifacts across frame and purplish sky, I wouldn't say it's on "top" though it is indeed one of better daylight shooters. Other phones like Mate 10 Pro and S9 have less details but clearly handles noise better than XZ2 does.

You must be refering to less noise reduction here. But it would loose great detail and texture that way.
Too much noise reduction as some other do it, looses detail and sharpness, and produces less quality image, so Sony did the other way around here.
And no, OIS wouldnt help in keeping the noise lower here, but wider apperture to keep the ISO lower, and thus less noise to reduce.
Tho even the noise levels are good and barely noticable here. Due to higher mpx camera.
Indeed, produces great low light shots, IMO better than some big competitors.
And Daylight ones are top, dont even have to discuss those.

The XZ2 is able to detect the presence of a tripod in auto mode and use a slower shutter speed, and hence lower ISO, to improve the image quality in lowlight. In handheld conditions, it will resort to using higher ISO, which reduces image quality.
