Strange camera artifacts - Galaxy S6 Q&A, Help & Troubleshooting

Hi guys,
Although I'm pretty happy with camera on Galaxy S6 in general I noticed that some photos have some noticeable artifacts. What could cause it? JPEG processing? Faulty sensor? When I try to re-create them they later on, they don't appear. Also sometimes when I enter in the camera app I have 2 sec of a graphical wobbliness and then it goes to normal, also when I try to purposely to recreate this bug/issue I have no success. Has somebody encountered this issue as well?

I have the 2 seconds of graphical wobbliness. The camera also make noises when that happens. Try opening the camera with rotation lock and in all possible angles, it's very easy to recreate the problem like thag

Don't worry
that's just lens settling up

[Q] [Camera] black screen when i try to open it

Hi,
When i try to open the camera the screen stay black, it happened many times yesterday. Do you think it's a software or Hardware problem?
Anyone else with this issue? (i've put a pin lock and try to open camera from lock screen)

I've got the same problem,
This is the thread I created;
http://forum.xda-developers.com/showthread.php?t=2514982
Basically the camera will work for a couple of hours and then it just stops working, the screen stays black.
I have Face Unlock enabled and this is a real pain.
I'm tempted to try a factory reset if nobody has any suggestions ?

[Q]Help about the camera and rotatres sensor

Hello, I am trying to get help to you
First. I have a problem because of the Nexus 5 camera
If I take a picture when vibration occurs
Shaking out photo
I saw this problem, I think OIS camera problems.
How do you guys think?
Second.
When an alert occurs, the screen rotates
Because of this error, getting the game to penalties.
I wonder how to solve this problem

Lines in Video

I've noticed that occasionally when recording video, I get bars down the screen, just random strips of colour. This appears in the recorded video too, not just while filming.
I haven't read about anyone else with the same issue, it seems to happen completely randomly but quite frequently. I think it happens on different video qualities too.
Is this fixable, is it a softeare/hardware problem?
This is what it looks like:

Bump
I have something similar when recording 1080p 60fps slow motion videos. It appears in the first seconds.
I also tried 720p 120fps and 1080p/4k in timelapse mode, and these modes doesn't have this problem. Will check if this issue is present in other video modes.

Same for me... It happens only using HFR modes and only in the first seconds...
I tested different modes and these stripes appears only on 60fps mode both 720p and 1080p. It looks more like a software issue to me

I've barely had my phone, only 4 days and I have the same issue. On all video modes, and different apps. It's similar to a rendering error you can get in Final Cut if you have dodgy graphics drivers.
Very annoying, and sometimes during recording the video crashes, and the camera suddenly can't be accessed until I reboot the phone.
Ya, i'm getting this issue as well, it works fine on a few modes, and it's only for the first second or two.
I can confirm this issue too. It's only in the first few seconds and using the stock camera app on CM11S. I took a slow motion video too and the same thing happened. Doesn't happen if I record a video using google camera though so I think it must be something with the stock ROM/camera.
This doesn't seem to be a common problem, so i wonder if it's hardware..... I hope not.
Hi guys, have the same problem [email protected] and [email protected] It is look like some autofocus problems.
One more thing: what setting of autofocus u guys use for normal speed video? Cause i discover that on auto focus camera wont change focus itself, i have to touch the screen.
Same problem, only in HFR modes....
Yeah HFR only in 1080p for me. 720p is fine

It's hardware.
this just happens after you install lots of apps. A fresh and wiped install doesnt happens.
Inside the chinese oppo forums is full of this nightmares. Oppo quality is a S#@$T...
Same for me in all kinds of apps...reboot usually fixes the problem...i doubt its a hardware problem...
This happens only if use "Continuous video" mode for the Focus mode. This does not seem to happen when using the "Auto" mode.
The same happens for me with CM13.1 and even in photo mode
I think I have read somewhere that those lines have something to do with the CM camera HALs. Maybe switching to ROM (like Sultans) may help.

[Q] Front camera exposure bug

Hello guys,
I don't know if it happens to you, but I've got some ugly bug on my front camera. Wherether I'm trying to shoot photos, I've some good exposure in preview, but after I shoot a picture, the exposure goes under or over exposure, but never the one I get on a preview screen (before hitting the button). Is this a known bug and is there any way to fix it.
I didn't see anyone complain about it, so I think it's not common. By the way, I tried to use different roms and diferent camera apps, it all the same.
The only thing I found on the internet is this site:
https://community.republicwireless.com/thread/26076
Yea, it's a common bug, that haven't been fixed.
To me it only happens in very good daylight and the photos end up overexposed, HDR doesn't help.

So I have this bug too, any pictures taken with the front facing camera outside during the day are almost entirely white, you can just about make out what the picture is of. But the preview and movies taken with the front facing camera are fine suggesting it's software. I have no screen protector, no case, unrooted, KitKat out of the box. Tried different camera apps with no difference.
I know this was posted a while ago but any updates on this? Can lollipop change anything? I have a moto g LTE in the US so no L for me yet. Can I adjust settings in the camera app (I downloaded the apk for the moto camera that has settings access)?
This issue, along with the multitasking problems that mean I can't even listen to music while surfing, have tempted me to give up on this phone entirely.

Dunno if it's fixed in Lollipop, but I can test. I just don't use the front camera much.
I got no such problem with multitasking at all, even on Lollipop, let alone KitKat that was way better in the memory management.

Thanks for offering to test it - I'd really love to know if L makes a difference. I don't often use my front facing camera either, but just knowing I don't have the option to use it is seriously off putting. Last week I ran into a friend of mine I hadn't seen in years, and after trying to take a picture together you couldn't see either of our faces. It was so disappointing.
As for the multitasking, it seems like some phones have an issue while others don't - all I know is that when I have Google Play open, launching Chrome causes Play to close after 30 seconds, no crash error or anything. Same with the home screen having to redraw after exiting almost every app I use, and Chrome tabs reloading every time I switch between them. I've gone as far as uninstalled the memory hogging facebook and other apps, but the problem persists. Painful is the only word for this phone at the moment.

Tested and I couldn't reproduce the bug on 5.0.2. It takes pretty normal pictures now.
Can you tell me if on KK you can enable HDR? On lollipop this is not accessible at all.

I have hope for the lollipop update then! Yes on Kk you have three options for HDR, on, off and auto.

Question Is it normal that my camera flickers on videos when the lighting level changes ? Does it happen on you too ?

It's not happening because of the lamps above, it happens on natural lighting too. It happens when camera focuses to a new area where the lighting level is different. Is this a defect, or is it the same for everyone ?
Here are 2 example videos:
It's really weird because it doesn't happen on the photo mode or on other apps when i'm taking a video, it only happens in the camera app video section. It happens on auto fps mode too. I tried taking videos with other phones on the same condition, and they just focus normally without that weird flicker. Is this a software issue or is my camera defective ?
Would be happy if y'all can help, thank you.

Already a Thread here:
Video Flickering at 60fps
Anyone else notice this? I did find a small thread on Samsung.com so not sure if its a hardware issue or if all of them have it. -...
forum.xda-developers.com
@hyelton check this, the exact same problem. Hope it's not a hardware problem and they fix it with an update
Yep same issue here. Glad I'm not the only one to notice the issue

Do you think it's a software problem ? Wish other people checked this and reported here too. Did you report it to Samsung ?
Does it happen if the camera is held in the proper orientation, i.e. landscape? Portrait mode should never be used for video capture. Hopefully in the future *all* phones will properly capture video in landscape mode regardless if the user holds it vertically or not!

What about a different camera app? I use Filmic Pro and have never seen this.
If I did, it would definitely raise cause for alarm!

Orientation and auto fps doesn't matter, it still happens. My post also says it doesn't happen on other apps.
I'm so happy to say that May update I just received (S908EXXU2AVDA) fixed this problem. Can you check if it's fixed for you too ? @hyelton I tried every specific condition that it flickered before and it doesn't flicker anymore, made me happy that it wasn't a hardware problem and they were aware of the issue.
Does it happen with adaptive refresh rate?
Because some apps flicker when this is turned on.

No, it was happening on 60fps video shooting, it's not about 120hz. It got fixed with the May update.
