Camera issue: low light = red blotch - Captivate General

Another captivate owner brought this to my attention and i wanted to see if I could replicate it. I didn't notice it on my own or with my pictures so I wouldn't say it's a big deal but wanted to see if anyone else noticed this as well.
In low light, taking pictures of a white surface shows a clear red tint/blotch in the center of the picture. Not sure why this would be, but it seems more evident in low light conditions.
Here are some samples.

Same issue here. It definitely shows up in the camera preview on the AMOLED

This is because the camera over-saturates the images. If you can find a camera app that lets you change those settings it would be fixed. The reason it shows up more on the AMOLED is because the AMOLED is already over-saturated.

I'm not sure that makes sense since the problem is visible on my computer upon export, which means that it's not just a problem while viewing on the SAMOLED screen.

Inspire 4G Camera Quality, Can it be improved?

Overall, I really like the Inspire. However, one thing I noticed, was the lack of "super fine" mode for camera. It also appears to have some exposure issues, despite tweaking. Does anyone have tweaks for improving picture quality (via lowering any compression that may be present, displaying hidden modes, etc..)?
Colors seem all wonky on my camera, like over saturated or something.
Anyone else notice any blurred edges? For example, my pictures seem to be blurred near the top right of every photo. Before taking the picture it looks fine, but goes out of focus when the picture is captured. I've also heard of other people having this issue near the top left corner.

I turned the "saturation" setting down to -1, seemed to resolve that issue.

I have not noticed that issue on mine. However, the images do seem a bit grainy, which is hard to believe, considering it is 8MP. That leads me to believe there is jpeg compression taking place.

Mine only seem grainy in unnatural light. Outside in sunlight this thing takes the best pictures of any device I've ever owned. Note: I'm no photographer, so "any device I've ever owned" is very limited, as is my photography expertise. I'm happy with the camera on the Inspire though
My camera works perfect.

I noticed when I was indoors setting ISO manually seems to work better than letting it set automatically. Sometimes it would be way too bright, sometimes too dark.
So what is the general impression about the camera? I've read and skimmed through a half-dozen reviews. Most say the camera is good, better than others, but all I really see is a blurry mess in the example shots. They also say the video is good, but I am not seeing that either. The brightness constantly changes and quivers and the video isn't very smooth or sharp. The audio recording is also very low quality and is my biggest complaint. This is in comparison to both a Samsung Galaxy S and Samsung Wave, which have pretty much the same cameras. And no I am not bashing the phone, because I might want to get it and like the other stuff like UI, alum body, natural-looking screen, etc. but am not to thrilled with the camera from the review pics/vids.

This issue seemed to resolve itself after adjusting the saturation to -1. The other option is manually adjust the white balance to florescent.

Or, get a replacement. much better now. Even the sales Rep agreed flash was green.

Changing the iso when using the flash helps too. Took a bunch of pictures last week and most came out really good.

Hi, i guess the quality of the picture will be great if you can sent the camera settings as follow: while you are on the camera mode, select menu= image adjustments= increase the sharpness to the limit, drag saturation half way down, contrast half way up, exposure half way down. by doing this, you will love your shorts.
I think my lense is kind of broken, as I see a red halo in the center of every photo I take. It's really annoying, although the saturation -1 trick improved it a little.

Strange black line on camera

Hello,
I have recently purchased an S6 and am loving it so far how ever last night I noticed that a black line appears on the camera when shooting in low light against darker backgrounds. I have been a little worried about it and just can't seem to figure out what it is. The camera functions perfectly in normal light. This issue only occurs on the back camera, the front camera is fine.
You can see the line especially well when a filter is added. I can't attach pictures because im new but I can message them to you if you wish to see!
Does anyone know what is causing this and should I be concerned?
Thank you in advance.

Camera Banding in Low Light

I just tried out the camera on my new Moto Turbo. I've previously used it under normal outdoor and home lighting, without problem.
But I'm getting banding in low lighting condition.
Banding is easily visible on light background. Also the camera is taking too much noise/ white grains in the left corner of the screen in low light.
Is this issue common with this phone ?
Yes this noise issue is common in most motorola phones. 21mp is just specs. Reality is very different. The photos are good mostly when used flash

The noise issue is understandable... But the banding issue is driving me crazy. I can see light grey lines running on my screen in some lighting condition. Even this is common ?

video quality issue, poor results (like color banding?)

Hi Guys!
I have recently bought the S7 (Exynos, Samsung camera sensors), considering the good price/performance ratio after reading a lot of reviews how good this phone was. Since I owned a low-budget 4 year old Huawei smartphone - which had a price tag about 25% of the S7's current price - maybe my expectations were too high on the camera and that's all it has to offer. Or is there some setting i'm missing?
I have tried a second device (about 1.5 year old), same circumstances, same results. Both have the latest Nougat firmware installed, no root or whatsoever. Photos are ok.
Both shots were made with default settings, automatic mode, HDR auto, flash off, 1080p/30fps:
1.) first I wanted to show my buddy with my new phone, what's the job he has to deal with soon (he is a painter)
vimeo.com/268656045
2.) when I saw the results, I made a second video in the kitchen, I would say rather good lightning than poor (although artifical), nevertheless same issue as seen in the first video
vimeo.com/270958764
(One more thing to add, Vimeo encoding did not cause significant degradation, what you see it's almost the same as you watched the original file.)
Why isn't the colour smooth? What causes those "waves"/bands around the somewhat yellowish focus in the middle?
It seems to be a problem with the "gradients". (nor sure if it's a proper definition of the problem, but the shadows have a similar effect on a solid/mono color surface as the light is less and less compared to the center) For me it's like the color banding issue, which AMOLED screens use to have sometimes, as I have read in several forums.
Thanks for any feedback and help in advance!
I get those banding circles if I take a photo with RAW enabled in Pro mode in bright light, probably just a limitation of the sensor under certain conditions
Could it be the colour depth of the sensor?

First of all thanks for the feedback! So you think it's not a malfunction, that's all the phone has to offer in such cases? I was wondering, that I did not read about similar complaints. No one has ever tried to record a video with similar background and similar lightning conditions? Or those who did, they never use to complain in forums?
Either way this result is disappointing.

Hi zeroprobe!
First of all, thank you for your feedback too! I really appreciate it. As far as I can tell, the video shows similar degradation like your pictures between 8bit vs 10bit, but what can be done? What does it mean?
Bump!
Did anyone experience similar issue while recording a video? Is there a solution or it is as it is, this device has basically a cr*p quality in certain circumstances? I wouldn't call it a great camera seeing this, rather disappointing.

Question Galaxy S22 Ultra green tint when looking from the top (bad viewing angles) Problem

My Galaxy S22 Ultra has a really bad color shift when looking from the top. The screen gets a green tint even when you are looking only a few degrees from the top. You can see it here:
https://imgur.com/gUDFh2Z
(It's more apparent in real life than in this picture)
Looking from all other angles than the top the display looks fine. But it looks like the screen is shimmering if you turn the phone a little. I tried to caputre the effect on this video:
https://imgur.com/e7PghPU
I have my display set to WQHD+, adaptive refresh rate and vivid mode. The brightness when I took the photo was around 60%, but the problem occurs at all brightness levels.
My previous phone, the Galaxy S20 5G, doesn't suffer from this problem. The screen does not change color at all when I look at it from a slightly different angle.
https://imgur.com/H2S3KwV
So I'm wondering if other S22 Ultra users have had the same problem or if my phone is just broken and I should replace it?
Thx for your help
I have to admit I don't "see" it. I think the brigthness and the rounded edges may cause a somewhat "dark" line depending on viewing angle but I don't think it's a defect.

I also do not think that it is a manufacturing defect because I checked all the devices around me and they were the same degree of green, do you think it is because of the new type of glass Victus 7 Plus
I had the Note20U and it was common to see that on the edge on white backgrounds, which is why you can't see it in "flat" phones like the s21U and S22 non ultra series. I think the same applies to foldable phones when viewed in a certain angle with white background.
Mine does the same if I look at the screen from a very off angle. Had not taken note of it though until you pointed it out. Guess I was just not expecting a good quality view from such a steep angle. Just out of curiosity, I looked at a similar angle at my computer screen, TV, Kindle, Tablet, and an old phone. They all have various degrees of imperfect display when viewed from a steep angle although the shift in color was most noticeable on the S22. But still, I guess I would not consider it a defect.

I am a user of all versions of Sam and all devices have different Vision angles, but the Galaxy 22 Ultra is annoying and I expect because of the 1750 nit brightness
Mine has the same issue. I bring it to the Samsung center. Their demo device was the same. So i assumed it wasnt the manufacture defect. And most of the time, no one will look at the phone from the top down like that. So that was not a big issue at all. We should be thankful that the grey uniformity is much better than those from Sony or LG. The grey uniformity in low light on those phone were abysmal
It's not a manufecture defect, this is "normal" to curved screen on some viewing angles, same happens with the flip and the fold and the N20U, the flat S21/S21+/S21U/S22/S22+ do not have this issue as there is no curve

I did not have this problem on the Galaxy S21 Ultra, and it was not that bad as is the case on the Galaxy S22 Ultra, the color of the screen changes to green, which is very clear for the simplest tilt of the screen

This is a problem, which is defined by the bad viewing angle, and it may be worse than the uniformity of the gray color, which may appear only in gray and in weak lighting conditions, but this problem is annoying because it accompanies you with all light colors, and it is a problem that appeared in the first batches of the Galaxy S21 Ultra and was referred to by some reviewers and it was widespread in the days of the Galaxy
It's faulty. My 1st S21 Ultra behaved the same way. Meaning it had a very aggressive color shift with the slightest of viewing angles. I understand OP fully.
I have the same green shift as well on my S22 Ultra. It was not there on my S20 Ultra. It is more likely due to "improvements" in the screen, what you gain, you lose elsewhere. While the green tint is there, it doesn't affect me as I look at my phone directly. Others trying to peep over my shoulder can enjoy the green shift.

Return it and get a phone from a different manufacturer or stop worrying about it.
Those are your only two options.
