Hi there, not sure if this is a common problem or not.
Whenever I take a photo on the phone it appears okay, but when I start to zoom in it comes out really blurry. The camera's set to 13mp and even on 9.6 it's blurry too. Is it like this for everyone?

The quality will get more poor whenever you zoom in. I haven't had any issues with poor quality while zooming yet, but I'll have an eye open for it.

Haha, I meant after I'd taken the picture. Back when I owned an iPhone 4 a couple years ago, zooming in after taking the picture was still crystal clear, and that was only a 5 megapixel camera..

Well... I think I get what you mean, and it has to do mainly with the resolution of the screen. When visualising pictures in a FullHD screen (2MP) the available real size is "only" 2.5times the display size on each direction. (Screen is ~2kx1k, 13MP is ~5kx2.5k pixels). And when you zoom in you quickly reach (and surpass) the real (sharp) size.
With an old phone (say 800x480) you had plenty of zooming to do before reaching the 5MP size.
The complementary reason to this is that the camera 13MP sensor is not proportionally sized with respect to good 8MP ones.
Having said all this, I find the quality of the S4 pictures to be OUTSTANDING for a mobile device.

Ah that makes more sense, thanks
Which mode/settings do you use? My pictures are good but nothing spectacular.

I usually leave it on Auto Mode although some times I do have to lower the ISO level because it tends to like high ISO values unnecessarily. I'm not a Pro photographer though.. there's probably some thread about tips and tricks to get the best out of it.
Thanks.
Post a full res picture here so we can see if they're ok.

Have you removed the plastic lens protector?. To do so, remove the back plate and proceed carefully with your fingernail

Yep, removed it
I'm getting lots of softness and graininess on the front camera.
I'm having the same problems with the front camera. It's so frustrating as it didn't happen with the S2!!
No mods on my s4. Stock camera. All the way zoomed out, it feels like its too close.
So for example, if i wanted to take a picture of a 36x36 painting, i have to be farther away to fit it into frame than my s3.
Has anyone else noticed this?

Yes, it is because the FoV is different on the lens. (field of view)
Thats the word i was looking for....
So im guessing this is not like quake 3, where i can adjust the FOV?

Not at all, its mostly because the megapixel count. cameras in phones cant have such a high pixel capture and great field of view all at once... yet

I just noticed it was very hard to take a full framed picture in a tight place.
Oh well.
On that note, could you just lower the RES to achieve the wider FOV?
Since the lense is better than the s3, the picture should still look better.

Not sure its the solution your looking for, but try using the panaroma mode... Its a pain, but theoretically should work as long as you dont need flash or anything.
Thanks for the explanation. I had forgotten the field of view is smaller on the s4. I was trying to tell my wife that the camera looks too zoomed in all the time. The Optimus G Pro has a better FOV than the GS4

Well, it's not quite like that. What you're seeing onscreen for the S4 is the aspect ratio of the pictures you're taking. So, you're getting an accurate representation before you take the photo. It's not anything but how it should be. The camera even thoughtfully has the aspect ratios of each megapixel setting in the settings menu. If you select a 16:9 setting, you get full screen because that's the aspect ratio of the S4's screen. 4:3 looks cropped because you don't want to distort your framing when you're lining up your shot. Just to clarify, this is a good feature, and not a bug.

No. This issue being raised is field of view, not aspect ratio. The field of view on the GS4 is smaller than on some other camera phones because the equivalent focal length is longer. A smaller field of view is not better or worse, it is a matter of personal preference. With a smaller field of view, things will look somewhat closer and close up portraits will look less distorted. With a wider field of view, you can get more in the picture, but close up portraits will have distorted, somewhat cartoonish look. This is because there is more perspective distortion as result of squeezing more in the frame. For reference, the S4 has a equivalent focal length of 31mm, the iphone 5 33mm, and the HTC One 28mm. So just on the basis of field of view/focal length, the iphone would the best for close up face shots, the HTC One, the best for fitting in the most on the screen, and the S4 in between the two.
yeah i'm a little disappointed because i like wide angle. but as long as you can take a couple step back, its no problem.

Has anyone heard the native aspect ratio for the camera sensors? On the Nexus 6 it was 16:9 on the front but 4:3 on the back. I can handle the front being 16:9, but if the back isn't 4:3 I will be seriously annoyed. I was hoping for a jump to 16mp so this would further hurt my pictures because I would be forced to crop down to 4:3.
If you know, please link to a source.
I may have answered my own question doing a search for sample photos turns up this:
http://cdn02.androidauthority.net/wp-content/uploads/2015/09/IMG_20150928_202643.jpg
It has a resolution of 4032x3024 which equates to 12,192,768 pixels. So that seems perfect for 4:3. Good job google.

in a world becoming far more dependent on pictures being viewed on 16:9 screens instead of being printed on paper, i find 4:3 to be highly annoying.

You can change it to 16:9 but you lose a lot of pixels
yeah thats the problem. it's been a struggle since nexus 5 for me
16:9 is good for Video and smartphone screens. Nothing else. It is horrible for framing a single photo.
just my 2 cents.
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...

the full screen disply on 16:9 is one of the main reason i choose to use it. It just kinda weird to have black space on the side.....
i havent try any other camera software.. any recommendation u have?

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
Sent from my Nexus 6P using Tapatalk
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.
