Articles like this try to shed some "light" :). It's actually more complicated, though, because of the mix of marketing terminology and consumer concepts regarding imaging. More photosites is more photosites, but they have to get smaller which leads to changes in noise/gain responses (SNR) even though sensors have gradually improved over time, and the Bayer filter (and other filters on the stack in many cameras) tends to cut the light to those photosites by a degree. Then color is estimated over whatever the resolution of the image is by looking at the nearby photosites, so color resolution is where losses often take place (but we have more attention to contrast overall and somewhat less to color). At the end of the day, the misunderstanding is as much on the consumer side (and sometimes reviewers) emphasizing megapixel count a lot (because it's easy -- larger number equals better, right?) as it is the manufacturers, with few trying to explain or understand the multiple factors and balancing between them.

Great article! Please can you add an option to your Phone Finder for standard Bayer filter or quad Bayer filter...I want a proper full detail sensor :-)

[deleted post]It might be a brick because of its camera bump, but I would be more than happy to have a smartphone with an absolute superior camera capability. One could say about buying a proper DSLR camera instead, but would I bring that heavy bulk alongside my lens all the time? No, not a chance!

Quad pixels doesn't reduce noise. 1/4 size pixels means they have 4x the noise. You blend the 4 pixels together and then you're back at 1x noise where you started. The added overhead of complexity might even mean that you're worse off.
Cameras that have 40M+ high quality pixels are enormous. Nothing will make them smaller until there's a way to focus light without large glass lenses.

Nick Tagataka, 10 Jun 2019Except when you have overexposed highlights on DSLR's image... moreDang I missed that last part. There s10 is one of the best with HDR. Among the top performers. Even the s9 and note 9 are way up there. Of course no phone is perfect. Even the new Nokia for some reason only squeezes out around 12 stops. Maybe that just described auto. However that's still great and can be worked with.
But the thing with samsung is that auto exposure is always a bit high. Better now but still high. However that's super easily adjusted. You just tap the lighter or darker area and exposure adjusted according plus gives a slider for further control.
Also I found that auto HDR rather than on produces far more superior stops of dynamic range. Although I think with the new 9.0 update its an option to use HDR or not when needed. Not on, auto, or off as it was.
Bracketing is great with my 808 but clearly limited so perfectly static and stabilized settings. And you don't even get a bracketing option now. At least not built in. Which not only should we but it should be much more advanced now too.

Of course though you can do much more with a DSLR. And sometimes they can do some HDR things too

What the article is saying is obviously clear. However these sensors have proven that at least at times there is definitely a detail gain compared to standard 12mp sensors.
Even with the Nokia 808's 41mp regular Bayer sensor not every situation showed perfect focus, iso levels, stabilization due to lacking ois, etc. So not every photo showed this astounding level of pure detailed shots. Though usually good enough due to resolution and natural processing.
And when it's good it's amazing.
So maybe because it's interpolation and not always perfect in every situation it won't be worth it or magnificent detail. But in good settings it can definitely squeeze out something. Especially in a raw.
I often have a tripod with me to use my 808. And let me tell you the level of beautiful detailed and accurate photos I can get blow any phone and many decent cameras right out of the water.

Phones have to resort to HDR because a single raw file from a tiny sensor can only contain a little information compared to one coming out from a larger sensor found inside DSLR. As I said before, if you want more contrasty image, just turn off HDR or use the manual mode(or just stop looking at smartphone cameras and consider buying a dedicated camera instead). The majority of smartphone users prefer HDR'ed photos including myself, but the options are there for those who like more traditional approach.
"phone actually make this light disappear"
My S10 and P30 don't, tell me what phones actually do such a thing?

Nick Tagataka, 10 Jun 2019When you look at the high contrast scene with your own eyes... morePhones get rid of overexposed scene when even Full Frame on auto mode would not do it.
Typical situation of light hits a wall, too much light that you can barely see what colour wall is, but phone actually make this light disappear.
I saw blind test with few phones and A6400 was used as reference. Pixel was very different from the camera, the most different. And anyone knows APSC are far better than cellphones.
