[Q] Front camera forcing noise reduction - Galaxy S 4 Q&A, Help & Troubleshooting

I love this phone and the cameras take phenomenal pictures, but the only thing that is really winding me up is the digital noise reduction that seems to be forced on the front camera if there is medium to low light. I haven't really noticed it on the back camera. What I'm wondering is that if I were to root the phone, is there some kind of mod released for the camera to turn off digital noise reduction completely? I've noticed an app called 'Silent Camera' does exactly that but it's a terrible app.
Thanks.

[Q] Camera Quality

Hey guys,
Got a M2 recently...my camera quality is always grainy for some reason...I've tried to change settings but it's still grainy. Using stock camera app and I've tried in many different lighting conditions and still same result. Any ideas?
Not only your M2 takes grainy pictures, mine too. I think it's a common thing for our phones.

not exactly. what i observed from my experience of using smart phones (moto milestone 2, dell streak, xperia x1), these phones take pretty amazing outdoor shots where there is sufficient light.
the reason ur getting grainy pictures is because the pictures ur taking is probably taken indoors or where lighting is limited.
try taking a shot where u have ample sunlight and be amazed

That is true. Just indoors is terrible quality. Outdoors it is.

u could improve the lighting indoors; ie use brighter lights, or adjust the angle of the capture to minimize the effects of shadows. buts thats the best u can do. at the end of the day, its a monster of a smart phone, not a digital cam. i suppose its picture quality is good enough. ive seen worse on a HTC Mozart with a supposedly better cam
I see. That is pretty true.
Does anyone know if this could be "repaired" with a software update, because the outside picture really look great and I might think, that the bad-light-pictures do just look so bad because of wrong calibration or so.
Not really a software issue, while they could try and improve the denoise filter the image gets passed through, all digital cameras suffer the same issue.
All CCD/CMOS sensors suffer from grainy pictures when there is insufficient light unless you have control over shutter/iso settings which can alleviate it somewhat. (eg, digital cameras).
I think for what it does, it does it very well and more than sufficient for a phone! As stated in previous posts, if your indoor shots are grainy, try adding some more light to the subject.
One thing I did note with the camera was that, if you have your 'scene' set to 'Steady Shot' it greatly increases noise and other issues when indoors.

Ok cool. That's handy to know.

Terrible picture quality

Does anyone elses camera take horrible pictures (I mean dreadful, unusable pics) when they're indoors or with dim lighting? Outside the camera is great, but inside, it sucks horrendously.
And I'm talking about without the flash
I downloaded a camera app to compare, and the stock cam app is awful compared to the camera effects app. At least inside anyway.
sent through the grape vines
did you try shooting w/ night time scene mode? I found that helps.
light... aperture... sensor sensitivity...
blame the realities of physics. not the camera itself
no, its not the physics, its the stock camera app. when i take pictures of anything black it does that,
i downloaded the miui camera apk and it seems to be a lot better

How to take good low light/indoor pictures?

Whenever I take a pic inside or in low light it seems very blurry. How can I take good quality indoor/low light pics? Thanks!

You'll have to mess with the camera and its settings manually to find a good way yourself. Simply there isnt a simple solution to this sadly. The S5 Camera doesnt take in much light in dark conditions which is a con to it. You could try setting the ISO to its hightest setting in dark conditions as a starter.

Don't go around asking people to thank you, especially if your going to give outstandingly dull and boring reply's like that.
I found if you have the photo setting Picture Stablistion on it tends to blur the photo on the edges you get much clearer photos with it off as I think it tries to take the photo without the flash in low light if you have that setting switched on. Hope this helps.
-Turn on Picture Stabilization unless there is movement in the picture than keep it off and instead use sport mode.
-Turn Up ISO
-Use the flash depending on the conditions.

Anyone else??
Any people find optimal settings for indoor/low light pics? Or perhaps another camera app that takes better low light/indoor pictures than the stock TouchWiz camera app?

Not sure if this helps, but I tried Camera Zoom FX to ease my front camera low-light woes, and it did indeed help a bit if you play around with the settings. There was much less noise than with the stock camera app. I didn't try it with the rear camera however.

Well I just use Snapchat for front facing pics (in low light conditions) because it has the cool feature of flash on the front camera! I wish Sammy would implement that into the Stock TouchWiz camera app.

Camera sucks without flash.

Why does my s5's camera suck without flash? It gets so grainy! And the front camera is also ****, my S3 takes way better pictures! Anyone else have this problem?
The S5 flash seems close to half the power of the S3 so obviously that makes a huge difference in low light, So this more than cancels out the S5s improved low light ability in the sensor.
Your camera has a problem. Clean the lens carefully and if it does not help, try to compare with another S5.
Cleaned it, Still same.. It doesn't focus as much too..
Low light shots without flash are terrible, well lit shots are very good though. I think your camera is normal.

I think so too. But what really annoys me is when the camera is on auto mode, you snap a picture in "sort of" low light, and the freakin "hold the camera stable until picture is takenÉ message stays on screen for like 15-20 seconds, How annoying is that? Other S phones never had that.
That second pic is normal for the S5 camera unfortunately in low light it not very good, you need to have a very steady hand and turn on image stabilization to get any kind of decent shot, or just use the flash if you intend to do any close up shots in low light.
As for the front camera I've seen worst, the best I've seen to date is from the iPhone 5S, no matter what lighting conditions are like it always gives a great image from the front camera.
Tbh i do find the S5 camera abit hit & miss in both picture and video, if the conditions are right then images are some of the best you see from a smartphone, with only the Nokia 1020 being the exception , but as soon as the light becomes slightly less than ideal it's starts to struggle, where the other's will do a better job.
I think Samsung have finally realized this, so when the Note 4 arrives it will come with a now rumoured new 12mp Sony Sensor with OIS & a F2.0 lens which should in theory give it much better performance in low light, and that being the case I will buy the Note 4 on launch come September.
try to turn on stabilization and hdr
After having used a Lumia Icon for two weeks, and having returned it during my "upgrade" window, it's hard to not compare the camera quality. My S5 performs very well outside in well lit scenarios, but most cameras do. I too have noticed the low light/indoor lightning suckage, especially compared to the Icon. I don't mind a photo being a little dark (that can be auto fixed with image software), but it's incredibly frustrating getting out of focus shots more often than not just because of a little less than optimal lighting situation (not talking about night shots). I leave HDR mode on full time now, and it has improved the quality/consistency some. I only use image stabilization in low light situations when I know there won't be a lot of movement involved. All of the pictures I take are through the built in camera app. I haven't ventured to other camera apps yet, but I figure it wouldn't make a huge difference.
Ultimately, I decided on functionality (android) over camera quality as I don't take pictures on a day to day basis to justify the lack of apps on the 8 ecosystem. I still enjoy my phone's use in my day to day though.
The camera is not the best, it takes several seconds to take a pic sometimes, which easily becomes blurry and out of focus... I wanna take pic not a movie, this hold still thing really annoy you after a while..

Turn off image stabilisation if you don't need it and that problem will be fixed. It's the image stabilisation waiting for you to stop moving the phone that is causing the delays.
Also, back on main topic... try manually changing the
ISO settings to see if high value is causing your issues. High ISO = noisy low light pic.

Post Front Camera Pictures

Hey,
Can I get some full quality pictures posted from the Note 4 Front Camera? Good & Bad lighting, With and Without Beautyface.
They don't need to be selfies, but I would like a few to be.
I noticed my Note 4 when taking front camera pictures and selfies suck compared to my Note 3.
I tried recreating the same pictures (same room, same lighting, same angle) I took with the Note 3 and the White Balance is way off, there are more artifacts, and distortion, and the pictures really are not in focus, especially at a minor distance on the Note 4. Even lights in pictures have an starburst/halo effect that others don't seem to get on the same shot.
I contacted Samsung and they had me pretty much clear app cache and data and factory reset the mobile. Not much help.
I wanted to see if this is just the norm for the Note 4 or if I have a bad cmos sensor or whatever before I send it for repair or exchange.
With full spectrum daylight led and cfl bulbs, all front pictures are yellow hueued. Adjusting the white balance helps, but shows more artifacts and can't be done in apps like snapchat, skype, google hangouts... pretty much anything you would use a front camera for that's not a camera app selfie. I even have a softbox setup with proper professional lighting and images show up with lots of artifacts and halos.
It's almost as if it's ever slightly out of focus and when the system API jpeg compresses it, it shows sloppy artifacts.
My cat took a selfie the other day! Lol! Not sure if this will get alot of replies. Most of us are too ugly for front camera shots

Yeah I know. Couldn't resist though. Hehehehe! I'll play around with it some and see if I notice what you mentioned. What rom are you using? Have you tried the camera mod and talked to the guy who's been modifying the camera apk? Here's the link...

I'm on Stock Rooted Rom.
I have used multiple apps with the same result.
Apps that allow you to adjust the exposure and white balance can compensate a little.
I have a feeling when Android 5.x is released for our phones, if Samsung updates the driver to allow raw images, things would get a lot better.
It would be nice if you could adjust camera variable defaults in the OS for applications that don't provide an interface to them.
I am definitely going to check out that modded camera app. Thanks for pointing me at it.
Even if it doesn't make a difference, "No audio interruption if listening to music" alone is worth it.

Yeah mine seems a little like that with the modded camera. I noticed the yellowed tint a little but it seems to be related to the lack of flash and it seems like it's being processed like it's in low light mode to make up for lack of a flash. Have you tried in day outside with alot of light? Might help a little. Not a fan of those low light/night modes. They are alway pixeled up and blurry. Look like sh!t most of the time. I've never used the front facing camera much on my phone or even on my computer. All my friends, family, and gf live here in town so I haven't had much need for it much. Sucks, I know, for those who need it. But!... Like you said, the lack of timer, audio interruptions and now that the camera works while on a phone call makes the camera mod worth it. Maybe the driver could be modded or at least the software related to it could be cleaned up by a dev or future updates might improve stuff some. You never know... Let us know if you think the camera mod helped any with the FFC at all. I just don't use it enough to know for sure. Thanks!

I thought this might be appropriate...
The AT&T version never took sloppy shots. I'm experiencing a poor performing front facing camera on the T-Mobile Note 4 as well. Solution is, use the rear facing camera.

That's an unfortunate answer.
I notice with face beauty set to 4 and up it creates a blur effect so I slide all the way off and my images are sharper but I haven't noticed and yellow tint that some of you are reporting.
