Why is 16:9 Ratio locked to 12MP? When the main camera is 16MP, 4:3 Aspect Ratio can go up to 16MP, so why can't 16:9? And could somebody possibly develop a mod to allow 16:9 to take full capability of the camera, I would try but I don't know how to, just a question I thought I'd ask, thanks in advance for replies

16:9 just isn't a thing for 16MP. On any camera really. I'd try to explain it but I'm bad at explaining so I'll try to summarize (or at least how I like to think of it, someone can correct me). Think of megapixel as a large portion of a photo. When you have 12 it's basically 4 megapixels across and 3 megapixels tall, making 12. 16 just adds 4 more to the top or bottom row of the photo. So it's not a limitation of the phone, just of cameras in general.

The 16:9 (12MP) Toggle comes enabled on the phone out of the box (at least I think it does) (and if not, the stock rom I'm using, the Creator might have switched it, but it's not mentioned anywhere else in his thread) and 4:3 (16MP) won't let a picture fill the screen completely, I know MP isn't everything when it comes to a camera, but it's just odd that it's a 16MP main sensor with it only using 12 of 16 out of the box, it's possible I'm not comprehending this and all the last phones I've had (GS6 and LG G5) Both have had camera mods that's gave them 60FPS recordings, improvements in general, and 100% JPG Quality, I appreciate your answer, and as I've said I might be just not grasping it or not understanding the reasoning behind it, just was digging around the stock camera app came upon the setting and thought I'd ask people that know more about this stuff then me. Thank you.
It's a hardware sensor limitation in the 16mp camera for the LG V20, and while you could get an app on the market that takes 16:9 pictures on the v20 by stretching the 4:3 picture to fit the ratio, I would just accept what we have ATM considering the alternative is kinda harmful to image fidelity
EDIT: Yes there is an option to switch to 16:9 with the drop to 12mp/6-mp depending on the options you choose obviously (just looked thanks to the post Joe199799 made just before mine)
This "degradation" in Megapixel count is actually fairly normal and happens in most cameras. My previous phone had a 13MP camera but recorded 9.7MP 16:9 shots. Here's a detailed explanation for why this happens:
If you think about how a camera works, light passes through the lens to hit the sensor. Making this lens round is the easiest option to make the image projected onto the sensor as close to reality without any distortion. Making the lens another shape would distort the image, ab bit like using the wide angle camera does, which is difficult to correct in post.
The lens projects a circular image, which you want to record as much of as possible. A circular sensor could capture everything, but circular content on rectangular screens doesn't make much sense.
The next shape that takes up the most area within a circle is a square. But at the time digital image sensors were developed, computer screens had adopted ratios of 4:3 or 3:2, slight deviations from the square.
As a result, image sensors were also built in 4:3 ratios, which sacrifice some, but not too much of the entire projected image. Now, with screen ratios favouring more width, we could adapt our sensors, however, to capture images of comparable quality, lenses would have to become larger or sensor electronics would need to shrink. Neither option is particularly preferable, which is why the 4:3 ratio has stuck around and most cameras recording 16:9 images simply crop out part of a 4:3 image. Because it arguably makes sense, megapixel count refers to the entire area of the image sensor. By cropping the image, the megapixel count will obviously decrease as a certain amount of pixels is deleted.

Thank you for the explanation it's very through and fleshed out, I think I understand now

I am a new owner of the S5 and after few days of using it a couple of things bother me. Could you guys shed some light/
1. The camera sticks out in the back a bit. Does that mean that when I leave my phone on a table, desk, etc. it will scratch the camera lens and all my photos will have the scratch marks? If so, what should I do -- have a really thick and bulky case?
2. when taking photos, the 16 megapixels are only available in 16;9. But in photography, generally pictures are taken in 4:3. Unfortunately, the samsung camera is only 12 megapixels at 4:3. So, if i want to highest quality picture, I cannot take it with 4:3. What do you guys use? I mean 16:9 looks nice on a TV, but so what. In fact the biggest flaw is that the front-facing is 2 megapixel but, again, at 16:9. And a 16:9 selfie is horrible!
If the table is flat and clean it won't scratch, the other end sits lower so the entire phone is tilted lifting the lens up for a tiny bit.
Photos I just take 16:9, if you need 4:3 you can always crop it later on.
It's not clear if you are seeking pragmatic solutions or venting.
Scratching the rear camera glass is not a big concern. The rear camera glass is recessed from the bezel, so it won't be scratched if set down or even slid on a smooth surface. If you take decent care of your electronics it's not likely to get scratched. A reasonable person wouldn't set their phone down on something like a coarse stone bench.
Nor are minor scratches likely to have an obvious visible effect on photos. If you are careless with your phone, then consider a case. Or buy some spare $2 camera glass covers and replace them periodically.
If you want an old fashioned 4:3 image, just crop the 16:9 photo. Done.
If you still feel that the 16:9 format is a deal breaker, then you only have yourself to fault in not researching your purchase better in advance. A 16:9 format is pretty standard for phones and it's pretty picky to find that a serious fault. If you do, then you can look at other phones or a stand alone camera.

but S5's 4/3 FoV is so small... compared to S4 or S3
And why oh why oh why can't the 7D have a full frame sensor????
I don't really understand your complaint. You can't change the camera in the way you are wishing for, so why are you bemoaning that it is 16:9? Either the overall package makes sense to you or it doesn't. You can crop the picture or probably find an app that crops the FOV as a default setting. You say that doesn't work for you. Fine. If the camera format is a deal breaker for you, then move on and get a different phone.
Complaining that you don't like the camera specs after your purchase accomplishes nothing other than venting. If you prefer an S3 or S4 or whatever model, then why did you buy the S5? Complaining after the fact only underscores that you didn't do your due diligence. The sensible time to have weighed your objections was before you bought your S5.
.
I take very good care of my electronics...and that's why I am paranoid and asking the question if I can easily scratch the camera even though I take good care since it is somewhat more exposed and sticks out. Generally, I leave my phone on its back while in the office or at home. The rest of the time -- it is in my pocket. I got an ultra slim case, which does not lift from the camera, so I was under the impression that I am not protecting the camera.
As far as the megapixels, do not get me wrong I am not complaining, rather asking what you guys are using 16:9 or 4:3. I used to be into amateur photography a couple of years ago, and back then the thing was to shoot in 4:3 always, regardless that cameras support 16:9. So, not sure of the trend has changed, and if folks using DSLRs for example are now shooting in 16:9. Now, for a selfie 16:9 is awful, but you can use an app like Retrica which always crops it to a square so no issues there.
I was just curious what people are shooting with 16 megapixel or 12.. or even less...
Hi guys
Noticed that on the 6p, the pixel were much lower if u choose 16:9
Which do u perfer to shoot with? 4:3 with more pixel, or 16:9 with less pixel?
and why you do it?
Thanks.
I prefer the 16:9 just because it fills the entire screen. It would be nice if we could have it both ways though.

I've been using both off and on. To me the difference is minimal. The 4:3 seems to be a little better in low light but in bright light I can't tell the difference. I've been using open camera app to shoot 16:9 and google camera to shoot 4:3. I haven't settled on one or the other as my main shooter yet though. I'm debating on trying pro camera to see how it does. It won't be the first couple of dollars I've wasted if it isn't any better. I'm trying to find a good one that will shoot stills while taking video. I got used to that coming from my note 3 and then G4.

I'm in the same boat. While I enjoy 16:9 mostly, I prefer to get as much quality to my pictures as possible with the 4:3 before any processing. That said - ProShot looks pretty nice, but unfortunately it's reported changing EV has been disabled? What a dumb move by Google...

I've tried several that are in the play store. For me open camera works the best out of the free ones. Search for open camera in the play store and give it a try. It had way more options than the google camera app.
Camera sensors are generally 4:3, even professional ones most the time are.
16:9 crops the sensor, hence lower megapixelsis

ALWAYS use 4:3 because only this way you will get all the pixels. You can resize it later and cut it down to whatever ratio you want - but you can never do it the other way round (without losing quality).
Yeah, the 4:3 vs 16:9 thing has been on my mind lately too... I like 16:9 pictures better, but when I compare the pictures I take, the only difference I notice is the 16:9 is basically zoomed in. You get no "wider" view, it just basically crops the top and bottom of the image off. There is a camera app or two that I've used that does make it wider, but those don't seem quite as nice as an image.

Well the aspect ratio of the sensor is 4:3, so it cuts of pixels until you get 16:9. Changing the aspect ratio without interpolation is only possible by cropping. Interpolation is what happens in the apps you mention which leads to decreased quality.

You don't get lesser quality when shooting in 16:9, it's the exact same quality. The only difference is the image is cropped at the top and bottom to achieve the 16:9 aspect ratio.
What's weird is the S6, Note5, and G4 have the full resolution at 16:9, where the 4:3 was a cropped version of 16:9.
I shoot in 4:3 to have the full 12.2MP image. I can always crop it later.

Use any picture editor that features a "crop" function and remove part of the top and bottom of the original 4:3 picture until you get a 16:9 ratio or any other ratio you like (e.g. 3:2 is also common). Done.
It's the same as taking the shot in 16:9 but this way you can decide later which parts of the 4:3 you want to cut off (only top, only bottom or part of both).

Well you technically could edit a 16:9 image down to a 4:3 ratio by cropping the sides off the image. Doing this will result in an image containing even less pixels though. If you're really worried about it just take photos in the 4:3 ratio and crop them to 16:9 if you need to. I just have mine set to 16:9 all the time, I don't like the look of images in the 4:3 ratio. Using 16:9 allows the images to fill the screen on my phone, my tv, and my laptop (mostly).

yea, the only reason i will consider taking in 16:9 is that it fills the entire 6p screen
Just got my G6 and was looking at the camera settings and noticed the 18:9 default aspect ratio of photos was an 8.7MP photo and 4:3 is 13MP. Well we know the sensor is 13MP, so obviously anything wider than 4:3 is just a crop. So correct me if I'm wrong but choosing a wider photo ratio in settting isn't going to give you a wider field of view, all it's going to do is crop out the top and bottom of actual photo the sensor is registering which you could easily do in a photo editor. But you can't put the top and bottom back in, if you set the aspect ratio wider than 4:3.
So what is the idiotic thinking behind defaulting the camera to 18:9? I'm guessing the average user might be upset that the photo is not taking up the entire screen on their phone. It's odd that these days there's all these tests, reviews and debates about what smartphone has the best camera, and then you have the manufacturing setting the default camera settings to crop out the top and bottom of your photo.
Yep, AFAIK, all camera sensors are round, while all pictures we got are in square shape. So, such wide pictures as 18:9, 16:9 are all cropped.

Camera sensors are not round, they are rectangular. The sensors native aspect ratio is what determines which aspect ratios are cropped.

I'm sorry, I have explain what I mean in the wrong way.
As we know digital camera*takes light and focuses it via the len (which is round) onto a sensor, and yes, the image produces by the round len is round.
And when that round image projected on the rectangular sensor, we got the rectangular picture. Using a nearly square will get most of round image made by the len.
A more wide ratio picture (18:9 for example) with the same quality as 4:3 need 2 things: a bigger len (to have a bigger round image), a bigger sensor to crop the wide section => both increase the cost and most important need a bigger camera part.
Hope I have make my opinion​ clearer. Sorry for confusion I made.

I don't remember exactly but didn't the camera say something about this when you first started it? Or when you headed into the camera settings for the first time?
I seem to recall being reminded that using 4:3 would use the full sensor at least so that would help people who aren't in the know.

Dear people from XDA,
My front facing camera records video's heavily zoomed in. Like my face fills the whole screen. This is while using the default camera app.
I do not have this problem when taking a picture with my front facing camera.
I have seen problems with snapchat and instagram, but I also have it with the default camera.
OnePlus support says i gotta clear cache, but that doesnt work. Now they tell me to do a factory reset.
I got the latest software update for the Oneplus 6T.
Any of you have this problem?
Edit: i cant post links so you can paste this screenshot in your browser with https:// in front of it. nl.tinypic.com/r/av0enk/9
Its probably to do with image stabilisation, it crops out the edges as that gives room to adjust for shaking. I could be wrong, but thats something I did for a dummy project before, I think its a pretty common practice thing

Like he said.. When it's in video mode, it appears to be zoomed in because it's cropping the edges as part of the electronic stabilization.*
I'm not a hundred percent certain on that being the explanation but I am pretty confident. That's just the way it works and I just open the app to be sure and there is no way to turn off this stabilization
I don't think it's as much about image stabilization as just aspect ratio. If you go into the selfie picture camera and change the aspect ratio from 4:3 to full screen, the image will be similarly zoomed in. As I understand it, the camera sensors are 4:3. To get 16:9 or 13:6 full screen images, it just basically crops the 4:3 image and stretches or zooms it to fit the desired size. Just like when you take an older 4:3 SD tv show and zoom to fill a widescreen tv.
I'm just speculating though, so I may be off base, but it makes sense. I'm sure someone will correct me if I'm wrong.
It is the electronic image stabilization. It crops the recorded area to leave room for the frame to move around, so that it can compensate for movement.

Interesting. Thanks for clarifying.
Hi everybody
This bothers me a while: When I switch from 12mp to 48mp in camera mode to do a 'wider' picture, the camera only uses a part of the screen although "full" aspect ratio is selected. In 12mp mode the whole screen is used for the camera. Am I the only one?
Thanks for your answer and explanaition (I don't have one).
BR
you have it backwards. the "full" ratio is actually cropped in order to fit the phone's screen. the 4:3 ratio has the full resolution and captures more of the image.
