S4 camera is really blurry? - Galaxy S 4 Q&A, Help & Troubleshooting

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?

Welcome to the primary drawback of digital zoom.

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.

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.

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

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!!

Camera Fix for the HD

I searched for a camera fix for the HD camera with no success. Does anyone know if there's going to be a fix in the near future? I'm sure that ya'll have the same problem that I do. Camera takes pictures that look old & rustic. Brownish tint to them & not very sharp for a 5 MP camera. I have adjusted all the settings for light & junk but nothing fixes it. As far as I'm concerned, it should take pictures IDENTICAL to a normal 5 MP digital camera. I can promise you that it's not doing that. Any help would be great, thanks in advance.

Why should it take pictures identical to a 5MP camera. The lens on the front is going to be vastly different, the sensor maybe 5MP, but what is the spacing on the sensor pixels? The closer together, the noisier the image. Colour balance will be down to the sensor too.
Regards
I'm not talking about the front camera. The normal camera on the back. I understand about the pixel thing, but it still shouldn't be so brownish, right? The pictures look like an old Polaroid picture. You know, the one's that spit the picture out as soon as you took it. Old, brown & nasty looking.
My pictures come out fine...
Hmmmmmmm...................... I'll just keep playing with it.

I'm not being flippant, but is it possible you might have a dirty lens?
Lol, that was the first thing I tried. Cleaned both sides of the back cover & cleaned the lens on the camera. Good idea, though.
The "5mp" doesn't really mean much, as stated earlier, if the sensor and lens are poor quality. As far as I know, HTC haven't released a phone with a reasonable quality camera, yet.
I bounce between different smart-phones (just coming back to WM now, after a year with S60). I can say that many of the S60 devices (in particular the Nokia N95, but also the N82 with Xenon flash) have very good cameras, being similar to low-end digital cameras in daylight. They lack optical zoom and tend to over-compress images, but have good quality lenses.
imho hd camera is excelent
pictures look old & rustic only if you make them inside house without using the artificial light setting, and this is also a general rule, not specific to HD.
Never seen a good phone camera yet, including the latest 8mpixel ones. They're all terrible.
Never
This camera will NEVER take pictures anywhere near what real cameras do. The photo sites are so tiny, they are smaller then the length of waive of light. Therefore noise, lack of dynamic width, etc. No patch will ever fix that. Sorry
open back cover , clean the lens , you will see a huge difference in quality

Not that I'm doubting you or anything but you do realize that the back cover only has a hole through to the lens?
You might try setting the brightness higher:
If you touch the small rectangle near the bottom right side of the screen (when holding landscape)
Then select the gear symbol, then select brightness from the menu and hit the "+" until it looks better that will remove most of the darkness.
The camera is a plain disappointment. In the time the camera autofocusses, I could have bought a Sony Ericsson C905's, create a good looking photo (with xenon flash) and upload it to imageshack.
If 'your object' makes the slightest move, your photo will be blurry . This is also the case when you attempt to make a photo of someone that isn't aware he or she has to be waiting for the autofocus lag. Head moves >>> blurry pic.
iPhone camera shots are way better quality, don't ask me why. Overall my Touch HD scores 8/10, where atleast 1 full point is taken up by the camera
and it's better don't speak about the very laggy video recording

Too many megapixels on a tiny sensor = major noise problem = blurring from denoise.
Even 2mpixels is too much for sensors this size, but people buy on marketing numbers of megapixels, not quality. You can just imagine the whining that would occur if the Touch HD came out with 1.3mpxiels, even though it would produce better pictures.

hehe, thats true.
mpixels dont count as much as the general public belives. the more mpix. the higher rezolution you can print the picture in. but for ordinary photos, 1.3 mpix would be enough, as long as the optics is good.
Personally, I rarely use a phone camera.
I use either my Olympus 720SW or Canon EOS.
​
the camera sucks **** compared to the n95 and the video recording is horrid. i know it's not meant to be as good as a dedicated camera but this is pretty bad given the price of the device.
i concur with mach03, move the camera a slight bit and eveyrthing gets blurred. one way i've semi gotten aorund this is to unlock the burst functiona nd take a sequence of pics and hope one or two coems out alright, not the most economic way to do it though...
i would ahve thought that maybe there's a way to tweak the camera to stop the blurring or even affect how much light is picked up by the lens which should also help with clarity

Something I find amazing about the S3 camera!

I've just discovered something very interesting about the S3 camera -its ability to use very -and i mean VERY high shutter speeds. I first noticed it in the EXIF data of a shot taken into a misty sun...a shutter speed of 1/10,000th second..so I decided to experiment a little to see what the shortest shutter speed the camera was capable of. I first took a close up photo of 250w infrared bulb filament with the bulb on. The result? A clear picture of the filament at 1/55,000th of a second! The highest I've seen so far is an only slightly overexposed closeup shot of the emitting surfaces of a 5w LED bulb straight on at 1/199,680th of a second!!. That's 1/200,000th of a second!!
This must be near a record for any consumer camera...now to find a use for it Filament photos becme a little boring after a while......

I've never noticed much noise in my S3 camera, besides at the reduced size of the images you wouldn't see noise anyway. If you're getting what you feel is 'noise' have you made sure your camera lens covering glass is scrupulously clean?
(BTW before the noise debate rises again I have a Sony module camera in my S3, my wife's S3 has a Samsung camera module and appears to have about the same noise level as noise as mine -both are excellent for such a small sensor)
nokia n8 camera can also do that for you...better than s3 i suppose!

Yeah, I agree. It's a brilliant shot with minimal amount of noise. The S3 does indeed have an excellent camera but it doesn't perform in medium to low light conditions as expected. For example, my friends and I went to a somewhat dimly lit restaurant. Let's say it was just above low light conditions. The camera took rather blurry pictures (as expected of moving subjects in low light conditions) and there was a large amount of noise in the picture.
I've attached the picture (it is cropped a bit at the top). You can see a large amount of noise on the blue table.
Actually, I wonder if the "party/indoor" scene in the camera might have resolved this issue. It seems to be doing quite a fine job on dark indoor pictures right now. Hmmm...
Really???

Hey come on now, that's low light.and I'd call the amount of noise totally reasonable for a high ISO, low light shot. The level of noise is way below the resolution of the photo..i.e.the noise is sharp the image isn't from camera shake. You're expected a lot from a phone camera. I've been a photographer for 40 years...from long before digital cameras and I'm very happy with the performance of my S3 in low light..I think it's nothing short of marvelous for a phone camera!
Samsung could have easily included more noise reduction for high ISO shots, but it would have reduced resolution, its always a trade off.
If you're worried about noise check out Noise Ninja..(for PC) with it you can select your own trade offs between visible noise and resolution on any given image.
.
Ah, okay. lol. Well, I suppose I have high expectations because I've been using a DSLR a lot for the past few weeks.
I just took a few more outdoor sunlight shots and they're brilliant! So, no big gripes with the camera.

Firstly experience tells me it's very bright...after all 1/200,000th @ F2.6 is roughly the same as 1/6000 @ f16 which is about 35 times brighter than full sunlight on a 18% gray card...that seems reasonable.given that it's looking right into a very bright light.
Second, I then metered it with my DSLR and got 1/8000th @ F22 at 100 ISO which equates to 1/256,000 @ F4 which is close enough for me.to the S3's overexposure at 1/200,000th @ F2.6 at ISO80
So I think it's both using a real 1/200,000th, and writing the EXIF data correctly.

ok, i'm quite satisfied with the nexus 4's camera but yesterday when I was comparing shots with my friend who owns an htc one x, i got a little bit jealous as her pictures had a wider angle lol. when she previews pics, it really occupies the entire screen. so are there any apps that can help me get wider angle pics or is it a hardware limitation? because my friend also showed me that you can change the pic dimension from 4:3 to 16:9 in htc's stock camera app, and i can't seem to find that in my camera app.
Try Camera MX. It's set to 16:9 by default

If you're talking about the screen, I agree our N4's view angle is nowhere near HOX. And there're no software could help that, it's from the design... pixel arrangement or something. Your another point, when viewing in Gallery, I also note that the portion where statusbar located is wasted, we can't use full screen. This happen to JB gallery while ICS gallery also use statusbar space. I'm not sure what the reason behind this. If you like, you can try QuickPic... it might use full screen, but I still think stock gallery is better.
edited: Pardon me for I confused "wide angle" with "view angle".... just ignore my reply then
AW: nice camera, but...
16:9 just crops the pic. You can just zoom to achieve the same. Sensors are 4:3 so it will just worsen the quality.
The other thing is the focal length. I won't go into detail as it is explained enough on the web, but the nex has a fl of 33mm in 35mm equivalent and the hox has 28mm which means it has a wider angle, thus getting more covert, but it also has drawbacks.
And btw, this is an interesting post:

Haha, if camera's that important, should have switched, or get a hand-held on the side, I guess.
discovered another flaw today. the screen of htc one x looks much more vibrant than the nex4.

Heh heh... with all other things being equal, there is essentially no advantage/disadvantage to either of these two focal lengths. It simply means that when composing the exact same picture, The nexus 4 will need to be a little further away than the HTC. Conversely, your friend will need to get closer. Sometimes it is easier to do one than the other, other times not.

Lines get bent. The wider the angle the more fisheyey it gets.
But that's the extremes. I just realised poster before me essentialy said the correct thing for this exact use case.

Camera seems too zoomed in?

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?

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.

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.

camera video quality

I took a couple of videos and the quality to me just isn't that great. This is with the UHD setting. Just isn't that clear for UHD.
I agree I had lots of noise/grain in mine. FHD60 seems a bit cleaner
This is a pic zoomed in half way. Looks awful. I bought this phone because the camera was supposed to be unreal. Is this normal or just maybe I have a bad cam?
Shot some video in a dark bar venue of a band playing. Using the main lens and manual settings, it turned out really well. The wide angle left a bit to be desired as shot but I think I have an idea for that lens. Shot with 1080 at 30fps high bit rate. Posted it in another thread over the weekend.
And at full zoom

Looks as though you may have a dirty lens.
The light in the room is a give away of grease or finger prints across lens. As the ceiling light starts to chase across your shot.
Same thing can cause grainy pictures. As it effects even a camera shot the same way.
Always try cleaning the lens if the shot seems to be poor.

Personally, I think the camera, both video and still, is the weakest part of the phone. I am not happy with that, but will live with it until the Note 8 comes out.
And you removed protector of the camera lens?

What other settings did you use? (ISO, Shutter Speed, Bit Rate, Filters?)
I will say that it looks like you're using the digital zoom, which is always problem #1. Never use digital zoom unless you have to do so. Whoever came up with this gimmick should be dragged out into the street and hung. It just doesn't get you anything but a mess. Optical zoom is optimal. Bipedal zoom is your secondary option. Digital zoom just shouldn't be an option. It is quite literally the option you choose when you want to have some sort of shot, any shot, and you don't care about the quality of the shot. This goes for any device from a cellphone up to a DSLR.

This was shot in a very dark bar venue with mediocre stage lighting. (Strike one against getting decent footage.) ISO 3200 (Another strike against any decent footage as you're maxing out the gain on the sensor.) 1080 at 30fps so I used a shutter speed of 1/60. I used the high bit rate setting. The refocusing is me touching the screen as I couldn't tell if I had good focus since it was dark and my eyes kinda suck these days without readers. I was playing with the audio settings and had no idea how to set it for a concert so I cheated and used approximately what I found for concert settings in the HD recorder app.
Considering the conditions..... the V20 did extremely well! I could pick things out in the audio that I couldn't live in person. In person, it was just a wall of sound sometimes. The video turned out amazing for being a tiny camera sensor. The only real thing I can knock the V20 on is the video stabilization. There needs to be settings somewhere so I can turn the OIS and EIS off and on so I know if it is on or off.
Are you using the stock cam app? I don't see anything where I can change the zoom type.

Yup, stock camera app. There is no setting for changing the zoom type. If you aren't clicking the one tree/three tree buttons, then you are going through a digital zoom. Only clicking those two buttons uses purely "optical zoom" although in reality, you're just completely switching cameras. (Different sensors and different lenses which presents its own issues since the wider view uses a smaller sensor and smaller aperture while the main shooter uses a "larger" sensor and larger aperture.)
Using pinch to zoom or the zoom slider means you're going through digital zoom. So if you start at the widest setting with the wide view and start zooming, the image quality is only going to get worse until you pop over into the main imaging group. Then if you continue to zoom, the image quality will degrade again. The best quality you're ever going to get out of any single focal length imaging assembly (which is what we're technically dealing with here, two single focal length imaging assemblies) is at its native focal magnification and at its base ISO. Which the photo options says is 50 but that's not always necessarily true, I'd have to look up the native sensor ISO online to be sure.
Did an unprocessed and processed test with my v20. By far the best dynamic range of any phone camera I've worked with.

The only positive thing I found about the digital zoom on the v20 which is unique in my experience is that when you're shooting 1080p on other phones, even though it's a 4k sensor it zooms up on the post sampled 1080p frame instead of taking advantage of the 4k sensor and zooming up without any quality loss. The V20 appears to do just that and up to a point there's no fidelity loss with the digital zoom because you're sampling a smaller section of the sensor..

Don't remove that. It helps protect the glass from scratches and shatter.

This is a pic zoomed in half way. Looks awful. I bought this phone because the camera was supposed to be unreal. Is this normal or just maybe I have a bad cam?

Did you gain any insight to help fix your grainy pic issues? I'm having the same problem. I keep seeing people suggest to remove the plastic protector but it has cutouts for the lenses and the sensors so I don't see how that makes a difference. I'm taking pictures without any zooming but when I take a look at the results and zoom in to different parts to review, it looks horrible and grainy.

What is your photo size set at? 16mp or 12mp?

I haven't. I wouldnt take the plastic off. As you said, it has cutouts for the lens. Not impressed at all with the camera
I'm amazed at your low light video. I also thought the camera was the weak point of the phone. Guess I need to work on my manual focus skills.
