There may be some proffesionals who do magic in Photoshop, though. The difference is very noticable in room conditions, when there's no Sun shining outside.

Sorry for being so amateur.

First of all we're talking about sensors, not sensors+lens+chipset. Second, why make a full frame DSLR if sensor size does not mean anything at all ? I've done a lot of comparison, surfing, sensor size determines pretty much everything - amount of light, crop factor( wider field of view, without any "fish eye" distortions), and most importantly "natural noise processing" as I call it, when any photo taken from a larger sensor, appears to be more natural than the one from smaller sensor, requiers less digital noise reduction which is the main quality killer. And this is why almost every single smartphone camera performes pretty much the same, exept for the two specific Nokia units. Perhaps we could count in the Panasonic Lumix 1 inch sensor, but it's more like a camera, than a phone.

Anonymous, 09 Mar 2016No.... Pixels would be stretched in 16:9. Just like 800x600 res is 4:3 and in 16:9 it would be... moreWhat are you talking about?
If the sensor is made with 16:9 aspect ratio, that means that the relationship between the number of pixels put on the horizontal axis and the vertical axis has the relationship of 16 to 9.
For example if we have 1600 pixels horizontal and 900 pixels vertical it has the resolution of 1.44 Megapixels.
If the sensor has 4:3 aspect ratio, the number of pixels has the horizontal vs vertical are 4 to 3.
For example, if the sensor still has 1600 in horizontal resolution, the vertical resolution would have to be 1200 = 1.92Megapixels.
But if the vertical resolution is 900, the horizontal resolution would be 1200 = 1.08Megapixels.
In a 1600x1200 senor it would be possible to capture either a 1.92 megapixel image in 4:3 or a 1.44Megapixel in 16:9.
In a 1600x900 you could capture either a 16:9 image of 1.44Megapixels or an 4:3 Image of 1.08Megapixels.
In neither case would that involve any stretching.
But the image from the lens is actually a circle.
And this makes things a little more complicated.
The biggest 4 cornered shape in terms of surface area, that you can fit in a circle is a square.
But by making the image wider than its height (making an rectangle), you can make use of more of the width of the image circle, the same would go for making it higher than wide.
(But since our vision is wider than it's height, that is not a common aspect ratio, and you could then just as well just turn the camera on it's side)
By making a rectangle, you can however increase the diagonal size of the sensor. So in terms of diagonal size a 16:9 rectangle will have a bigger diagonal than a 1:1 square, even though it's area is smaller.
Since the biggest 4 cornored shape is still a square, making the sensor less square shaped will make the surface area smaller, and thus decrease the resolution.
Some maker have used a sensor bigger than the lens circle, to then allow users for to select the aspect ratio they want, but making sure that you get maximum resolution from each. That way if 16:9 is selected, the user gets a bit more of the width the image the lens actually produce in it's image circle, but lose some height, and if the user selects 1:1, it will get the highest resolution, but then with a less wide image. 4:3 would be a compromise between the two.
So in the examples above, the 16:9 sensor would most likely capture more of the width of the image circle. Whereas the 4:3 sensor would capture more height.
So selecting a different aspect ratio in software on a sensor means that the captured result it's not comparable to a sensor made for that aspect ratio, even if the resolution would be the same.
Since the acutal sensor behind the lens differ in size depending on if it's a 16:9 sensor or a 4:3 sensor, when calculating the F-number (aperture), it will be effected by the sensor chosen. The wider 16:9 sensor would need a bigger image circle than the 4:3, since it's using more of the width (it would need a image circle that is as high as it's wide).
So if Samsung would use the same lens, but put a 16:9 sensor behind it the f-number would go up, and that is worse, since higher f-number means smaller aperture, but the actual aperture size would be exactly the same.
So it's considered that perhaps Samsung chose the 4:3 aspect ratio in order to have a better f-number. However, then one could as why they did not go full square. But perhaps that would result in a number that when rounded off, it would still be the same (I dont' know exactly how to do the calculations, so I won't bother).
Another advantage is that they can post higher megapixel number.
And that in the interface on the 16:9 aspect ratio screen, they can fit on-screen buttons to do the settings, without distracting the user from the actual aptured image.
Also a lot of users of mobiles, tend to hold their phones in portrait mode, even when looking at images and watching videos, so having a more square resolution would mean less borders around the image, and less downscaling.
[deleted post]Little boy I will take GSMArena's word over yours. They showed that the Samsung sensor was better at day and the Sony was better at night. Nothing unbelievable.

Compare the 16mp sensor in the galaxy s6 and the one in the new huawei. Both 16mp, both from Sony, both 1,12 um pixel size - but if you look at the sensor size its 1/2.6 at the 16:9 sensor and 1/2.8 (smaller) on the 4:3 sensor

That means your focal length increases for the same focal length equivalent, that means your aperture has to be physically larger to write a F/1.7 on it, your camera humb would be bigger etc.
