Many of the cheaper phones which claim to have 48 MP cameras use an interpolated solution to provide a 4x12 MP image. I can excuse companies to use this method on very cheap phones.
Samsung uses (Tetracell) technology from late 2018 to create a hardware computed 8x4 image while claiming to have a 32 MP camera, this clearly shows when zooming in to crop an image, the blur is real unlike my S8+ f.ex. which actually only has a 12 MP camera. I want to shoot 16:9 photos and these are strictly limited to 8 MP, 4:3H does produce 4x8 but it´s still nowhere near the quality of the S8+ 12 MP camera. I was naive to think that Samsung wouldn´t pull a trick like this on their customers, the shots at low light clearly show the limitations of the camera.
I called Samsung support in Denmark and explained the problem, the lady told me I could choose whatever picture size I wanted in any aspect ratio.... she told me to wait as she was going to find out how, she came back 5 minutes later and told me she couldn´t do it on her models ... of course not, I already knew that. I left her my email because she asked .... not going to do any good.
The pictures are nice for the most part ... just don´t zoom. My Umidigi F1 for 180 dollars takes overall worse pictures but the zooming is far better on pictures as the lines are straight without blur regardless of how much I zoom in, it does not have any low light capability however.
PS: HW sensors will report the cameras as 8 MP because they don´t understand the 4x8 technology. As it is I believe all third party camera apps will detect the same and be limited to 8 MP.

I cant seem to differentiate between 12mp and the 16mp other than the ratio size. I cannot notice any drop in the quality when viewing the pictures normally and zoomed in from my phone or maybe I think my eyesight is pretty bad . Can someone help me over here?:fingers-crossed:
Megapixels doesnt influence the picture quality of a camera, its sensor does. megapixels determine the size of your picture so for eg you can have a 50 megapixel camera but if the sensor is bad you wont get a good picture and vice versa, which is the reason that older dslr and point and shoot camera's still out perform many modern day phones because they had big sensors specially the dslrs. until and unless you are going to print posters and heavily zoom and crop a picture 12, 16 or 20 megapixel is more than enough.
Using A7 (2017) and thinking of upgrading to A70, but not sure technical specs wise if the Front-Selfie Camera, would be much better than A7 (2017).
The Culprit = Aperture.
A7 (2017) - 16 MP, f/1.9
A70 - 32 MP, f/2.0
Now I take loads of selfies and low aperture is very important for me. The new A70 has one stop higher aperture as compared to my 2 year old phone but yes the megapixels is big but tht hardly matters in how much light the module lets in.
So according to specs, shall I conclude the front shooter is equal or maybe slight worse than my current phone ?
Need inputs.
The difference between f1.9 and f2.0 is not very significant, the quality would depend more on the noise in the chip I'd have thought. In whole f-stop numbers, you'd need to go down from 2.0 to 1.4 to double the amount of light allowed in by the lens, f2.0 to f1.9 isn't even a third of a stop, even if these were real f-stop numbers anyway.

UPDATE: I got the chance to demo Live A70 and I was shocked with the performance.
The selfie camera takes photo as if heavy beauty mode is applied by default. The rear camera takes "Greyish" pictures and even video colors were way off.
Compared to my A7 2017 it was a clear downgrade and even the Samsung representative in the store agreed with my inputs...
So am sticking with my current phone for now and possibly will switch to Oppo Reno !!
So you took a couple of quick photos with store demo unit and decided that camera is bad? I'll rather trust reviewers who spend days with the device before giving impressions and actually provide picture and video samples and comparisons with other devices.

I thought something was fishy with that demo unit... as it was on Demo mode and while taking selfies there was no option to disable beauty mode.
I again tried a demo in a local shop with consumer mode - and I am happy to inform that the pics and video all seem normal and satisfactory.
BTW, Greyish tone in pics can be widely seen in reviews too!
Camera is not great at all. It is normal as other low cost phones. Also
Bluetooth is breaking a bit with head phones.
audio for receiving calls is poor.
cannot connect to external monitor with type-c to hdmi which I feel is a basic feature.
it is high cost product.
Overall for this price, it is not a good product.
Until unless some one want new phone like me, its good to wait and check for other models.
So ,I was skeptical of posting this ,but maybe it can be a spark for new development
At first ,I believed that perhaps the camera sensor in the A70 is just 8 MP and some marketing jargon made it appear 32 MP
Idk if this app is true or not but it's actually identifying the sensor as a proper GD1 Samsung sensor with resolution of 32 MP
Yet ,the software is only reading 8 MP from this sensor ,which may mean that there is probably an issue with software rather than hardware
I am no expert ,but I thought this might help us to perhaps unlock our device's full potential
the came api responds to the apps (gcam included) that the camera has only 8mpx
is the api
there are devices where peolple with root and twrp can change this
but it is not working on A70
It's a 32mp sensor, we've always known this. 32mp IS available but only using Samsung's own api, which is only available (so far) in Samsung's camera app. You can verify that yourself by taking a photo in 3:4H mode. Look at the details and the res will be 6528x4896 - 31.9 million pixels. So it's real and it's there. I also don't understand why people are chasing this mode when it's been shown that it's no better than the usual 12mp mode. Would what be nice though is having access to 12mp through the Google camera api, this would allow 12mp in gcam for example, instead.of the 8mp we are currently stuck with. Not.that the photos are bad in gcam but I believe theres a bit more detail to be resolved if we had the full 12mp.
Yes, pics taken with the GCam are good. The pic and resolution quality is acceptable and a level above the Samsung app even in 3:4H mode. But the quality is still a level beneath my Iphone7, in my testing.
Still hoping to see a high MP Gcam or significant software updates to the Samsung camera app.
Thanks to everyone for the reply
It's just annoying as hell to have low megapixel count ,because I usually love cropping into my photos and it really limits me , specifically because of a lack of telephoto lens as I love architecture photography
Another worthy note : I tested over 10 apps that check the hardware info of the phone
None of them could manage to identify the ultrawide cam nor the depth sensor ,all of them only identify the front and back camera...which probably mean there is sort of hope that maybe the Camera2API provided by Samsung is not really fully unlocked and it strict the readings of the entire camera module
If a developer could clarify why the ultrawide isn't identified I would be super happy
Maybe its an advantage of not owning a flagship phone before coz I have nothing to campare the cam of A70, but for me the 32mp mode is really good specially when using outside with good natural light, the zoom image is very impressive imo. Yes the gcam takes better images overall but I really love using the 32mp mode from the stock camera
I love the Note 10/+ cameras, but the lack of support for the Wide Angle and Telephoto cameras in Pro mode and not being able to get DNG/RAW files with that sensors is a reason for me not to fully love the phone's camera setup. As far as I know, all cameras have the same sensor, so really it wouldn't be much difficult for Samsung to let us use those cameras in Pro mode via an OS Update.
Other manufacturers like LG and Huawei let me take RAW files with other cameras (I've had the LG V30 and the Huawei Mate 20 Pro), and if you are a photographer or at least know the importance of RAW files, you should understand me.
I shoot professional photography on my DSLR, but when I leave my camera at home to go with friends or to a live show, having full camera control on my phone would be really appreciated knowing how easy would be for Samsung to let us do by software update.
Edit. Misunderstood at first
Each sensor is different: normal and telephoto are 12MP, ultrawide is 16MP, telephoto and ultra wide are 1 micron sensors, normal has 1.4 micron pixels so it's best for low light and I think ultra wide has no auto focus? But that's no excuse, those cams I think are the same as S10+, so are around for at least 6 months and should have enough time to properly update software.
I remember when Note3 came out it was one of the first, if not the first phone with 4k video etc., I don't see that bleeding edge anymore. For example Huawei has 40 MP sensors and better low light capability. Maybe Samsung is adopting Apple strategy to make the phone just good enough and leave newest tech for next generations, but that could bite them back.
In S20, when u set the camera for 3:4 64 MP, the zoom goes only upto 6X. In other settings using 12/9 MP, it goes all the way upto 30X.
Now, when you have 64 MP at your disposal, this format should be more amenable for 30X than 12 or 9 MP format.
Further, I find that 64 MP, 6X does not produce any better image than 12MP, 6X. After 6X, the resultant image with 12 MP contains 2MP & with 64 MP, it should contain 64/6 = 10.6 MP (if it is a crop) & so the latter is expected to show much greater detail without pixelisation. But actually it's not so.
And even after 6X, the file shows the picture contains 64 MP. How's it so? From the quality, it appears like a digital crop rather than optical zoom.
I really doubt if it contains 64 MP.
Did any of u guys observe this?
Think the sensor is definitely 64mp (without zooming in at all), but as soon as you zoom etc it behaves in a hybrid manner, not in a typical cropping manner.
Well, sometimes cameras marked as 12MP are actually higher MP sensor, but they take for example a 16MP image, and reduce it to 12MP and mark that as a 12MP sensor, this way they can get better images
I think that's not the case on the 64MP, it's REALLY 64MP and they didn't cheat anywhere, so if you take a 12MP section of the 64MP base it's not so great because it's not like a smaller sensor where it's cropped intentionally.*
In fact, digital zooming have the advantage of being able to have use of the whole sensor if you want to, and therefor get extreme good quality images, but when zooming in it's never as a good as an optical zoom
