Hi,
I've noticed pink spot/hue issue in the middle of photos taken by main camera my S21 Ultra (Exynos version).
I've checked that some condition must be met to recreate the problem:
- photo must be taken indoor when sunrise appear (but it should be dimm in the room not bright)
- photo taken outside when is cloudy (there is no sun)
- the light must be natural
- on gray and green (khaki) surfaces defect is more visible
Do you also have this problem?
I was send phone to service center twice:
first time camera module was replaced - unfortunately the defect remained
second time - the service stated that the phone and camera is functional
P. S. - laser AF is not a cause - I've covered up and hue still exists.
I've searched forums and found similar problem with xperia z3, htc, galaxy s5 .
I dont know if this is normal, or maybe software update will fix the problem or maybe this is hardware failure?
Really...don't know what to do anymore.
Have you tried to replicate the results using another camera app? If it looks the same, then it's not software.

Yes - hue was visible in other applications as well as in the service menu.

Definitely a hardware issue buddy... Keep trying with Samsung, print the images you showed us here and give them with the phone so they can see directly and not test it barely and not notice...
@nevellan
Good to see that you created this thread.
I've been noticing the same too from the beginning. Enquiring further, I noticed the same in two other units later. (All Exynos).
I did not /do not see the pink hue when the laser AF is covered.
However, my concern is why to have the pink hue in certain lighting condition irrespective of laser AF is covered or not! This is an issue.
... have also noticed that the pink hue disappears when focus enhancer is ON.
Pink Hue dissapers when focus enhancer is ON,becuase then is used wide camera not main (108 MP).

Try to hide the laser lens..if you still have this , it's a faulty main lens .

Not sure*.
Could be firmware.
Try:
Clearing the system cache
Clear cam data
Hard reboot.
Check cam settings; excessive contrast or saturation could cause it.
A factory reset will do nothing more than likely.
*test to see if it's purple fringing with some high contrast images ie backlit subjects

I did everything you suggested many times - it didn't help.
Covering laserfocus doesn't help either.

I'm having a similar problem with a purple patch in the middle of the shot but only when photographing black objects in less than ideal light conditions, particularly black materials. The problem exists with the main camera and wide angle, Zooms seem ok. The problem also exists using GCAM. If I force flash there is no problem. Doesn't seem to be an issue in any other circumstances. Strange. S21 U Exynos 16gb.
I ve noticed this too, but only on the gray colors. I am up to date with the software version, july patch. Exynos 256 GB.

Plus, i haven t notice this thing until seeing this thread and tried to photo something gray, so i think this is not a big deal.

Ignorance is bliss
Looks like only Exynos devices are plagued with this defect, one more reason to pass on this problematic SoC.

I have a htc Kaiser and there is a problem with the external 3Mp camera. When you start the application to take photos, then appears two parallel stripes, one half yellow hald red, and other below half green half blue. This happens only in the external ( 3 Mp ) camera, not in the 3g one. How I can fix it ????

Clean the lense
I have the same problem.
Tried cleaning the lens, didn't work.
Hard reset didn't work either.
Seems like a hardware fault with the camera.
Wait, are you saying they appear in the "viewfinder" of the app, or the actual photos?
Post an example shot please?
Mostly, It's cameras bug.

Was that supposed to be an answer to my question or a response to someone else?
Really, it's not possible to say whether this is an unusual "feature" or a bug without more info. The way the original poster describes it, it sounds like it might be some unusual framing assist feature in the live preview. No one seems to be willing to say whether it is in the previews or if it is in the actual pictures taken. (I know I have seen the Kaiser pictures thread, and they look pretty good other than some obvious deficiencies in the debayering algorithm that cause "maze" patterns to appear in certain situations, which is a common problem with some of the older/simpler debayering algorithms.)

yes, good question. does it look like this when you view it on your computer, or is it only when it's sized down on your device?
I can see the stripes while taking the picture and they are also part of the saved image. Viewed on the TyTN II and on a PC.
The camera was working fine then all of a sudden just started showing stripes.
Attached are some photos.
Looks like i might have to send the TyTN II for repair.
I also noticed that when you take the battery cover off, it seems like the camare can be taken out, so it may have moved and not making a good contact.

lol my first glance and it looked like you were targeting things with a crosshair. yea thats different than the lines i hought you were talking about, you need to send that back for repair.
Yeah, definately something wrong there, likely broken hardware.
Also I have the same problemna!
This happened to mine too, after working fine for about a month. Seems like a common problem, interesting it shows up after time too. I sent mine in for repair/replacement but it may happen again....
Even my own, for a month everything was ok, then is the line appeared
Same Problem
My camera also did this. I changed the flicker adjustment in the camera settings to 60 hz from auto and it went away, only to reappear again. Again, I changed the flicker adjustment, this time to aut, and it went away again. Very strange. It appears I can paly with the flicker adjustment in the camera settings and make it go away, at least for a while. It appears to be a common problem, likely software related.
i too
hi i too experiance the same problem.......
is there any one to help us... please post a geniune reply to our problem
My camera has problem like this. i took 2 shots at the same place and with the same light !

Anyone know how to fix ? Thanks
Some obvious things:
- Have you changed ROMs/Kernels between shots?
- Did you change any camera settings? White balance maybe?
- Have you checked the lens to make sure it is clean?
Bit hard to tell what has happened without knowing the above.

+ I have tried several ROM (stock GB, stock ICS, CM9), and still got this problem
+ I did not change any thing in setting
+ How can i check lens ?
Not sure there is a way to check lens apart from viewing through camera. I clean mine with an alcohol wipe when I clean the back of the case. You may have some grime on it.
If you have used different ROMs then must be related to the lens I would think. I have noticed that the camera is not so good in room under night time conditions, but does do excellent job outside. Have you tried taking outside shots during the day?

No - I onlu clean outside of it very carefully. If you have done that and outside shots are the same then it seems like it is a hardware problem. Did you take any shots of the Sun (silly question I know but with the Transit of Venus last week some people may have pointed phone at Sun and cooked their photo receptor)
THe only other thing I can suggest is to select Reset from Camera settings and then see if that undoes any weird settings that are affecting the picture.

Good day fellow Butterfly S users!
I'm new to this forums and I was looking to expand my knowledge on this area.
First off, if I root a phone, what are the pros and cons?
Secondly, if I did root a phone will it get rid of the pink/purple tint with the camera? --Since I read somewhere that this is a software problem..
I notice a somewhat pinkish tint whenever I use the camera in lowlight. I tried reducing the ISO to 100 already with still no change.

Rooting won't magically solve any problems with your phone. Rooting won't give your phone superpowers. Assuming it really is a software problem and a solution does exist (such as a modified camera app or firmware or kernel driver), rooting would most likely allow you to install that modified version on your device. Other than that, it won't affect your camera in any way.

AFAIK the generally accepted explanation is that the issue is HW related and caused by the image sensor's sensitivity to heat. I read about a user somewhere who performed tests and found out that the purple tint starts to appear on his device when the temperature inside the phone is >28C. His phone was a HTC One, but the same goes for the Butterfly S, too.
Personally, I did not run any such test though, as my device seems to be among the lucky few which are not affected by this phenomenon :victory:
I attempted to produce the purple tint using the following test after I purchased my phone:
1) 30 minutes of NFS Most Wanted, which "preheated" the device quite nicely ,
2) lights off in the room, so it is lit only the backlight of the screen of my laptop. (this ensures that a high ISO is selected by the camera)
3) camera on -> take some test shots
They were niosy as hell (due to high ISO), but thankfully free of any discoloration.
As for rooting...
If this is the only reason you want to root I would say: don't do it. By itself, rooting wont solve your problems. That is a fact. Rooting could enable you to apply a SW-fix though, if the issue was in fact a SW-related.
I have a problem with my camera if I'm using it in dark situation
It always catches somethings with unusual color - attached (example 2 photos taken with something stick at the camera which means without light)
and I attach 1 more photo taken with some range to the object(the same object), as you can see there's still not very clear picture
I've seen the thread about the problem like this :
http://forum.xda-developers.com/showthread.php?t=2317507
But I realize that it's not a noise problem (ISO controlling), so is there anyone know how to fix it?

you have a bad st electronic camera sensor and they will change it for an omnivision sensor or any other brand, not sure which one they use now.

Hi, dude,
This is a normal physical effect, which is called 'Antbamding' (50 or 60Hz).
in previous versions there was an option in camera settings "Antbanding" to minimize that effect.
for more Info 'google' it!
I do not see any option in Gcam for anti-banding
I am also experiencing this, vertical bars for BOTH front and back camera. Was at restaurants in low light environment and took these, using portrait mode, night mode and normal mode.
Yes, this is the same issue I have experienced on both front and back camera in artificial lights.
Seen this during day time, indoor shoot as well as night time indoor shoot
Ok. That's 2 of us... Is this normal/expected camera processor behavior or do we have defective units??
A couple others have reported this as well. Even in few of the youtube videos comparing Pixel 7 with other smartphones, I was able to catch this on pixel 7/pro display.
I do not believe this is affecting just vanilla 7, but 7 pro as well.
I hope others chime in with their experience by shooting under different light conditions.
I had such a problem when I put on a cover. It turns out that there is a sensor between the two cameras, and my cover did not have a hole for this sensor. I had to make a hole myself. Everything is fine now. My pixel 7.

What case/cover it is?
I have the same issue...
Issue is seen even without any case/cover in my case
Workaround - Start the camera in selfie mode and after 1 second switch to back camera.
Update; i exchanged phone as it was new and replacement phone does same thing, so it is a " bad behavior". Work around is to play with the lightness bar when taking pic. Banding stops at a certain point, but what a pain..
This isn't a defect per se, it's image banding.
Likely from LED lighting.
Try decreasing the shutter speed under a 100th of a second while keeping the exposure like in pro mode.

There are no such options in Google Camera app. I see the same response being posted all over the internet for such problems (reported on Pixel 6, Pixel 6 pro etc.)

That's a normal digital camera phenomenon, not a defect. That said I can't get my N10+ to do it with LED lighting. These ones probably aren't pulse modulated though.
Use the phone's led, another led light source or incandescent lighting to back fill the shot. You need to slow the shutter speed otherwise or shoot at a higher ISO.
