Not sure if i'm not searching hard enough for old topics related to camera of sgs2.
i noticed that there are vertical lines/waves or whatever you call it when taking pictures. it appears on certain light conditions and surfaces. light brown/flesh and whites.
is this normal? if not, is it hardware or software issue?

anyone?
cant c the lines but may b lens is dirty or some thing on the inner glass
not me........... try wipe or flashing stock ROM and see again
Ya now I c it atifsh is right.an u can flash the camera firmware.
Sent from my GT-I9100 using xda premium
i think the lines are caused when you're under florescent/CFL bulb regardless if daylight or warm light.
this does not occur under incandescent bulbs
i have the same issue...
I took the phone apart, cleaned the len and the cover and still get the same result. The lines wont go away.
Someone mentioned you can flash the camera's firmware?
I've tried different firmwares aswell... CM9, MIUI, Hydrog3nics... all of them resulting with the same issue... I should try on a stock rom...
I would apreciate it if someone with a stock rom can take a picture of a white piece of paper with flash off under fluorescent light and please post the result...
Thanks again
The one i posted is already stock rom, stock firmware camera (dxlp7) under fluorescent light (office lighting).
I tried to reproduce it using ordinary fluorescent lamp and dont have this.
i think, might be wrong here, the problem is the interference (electrical or something) that causes this waves. i tried taking picture vertical still under the same lighting and don't have this anymore.
i just want to raise the issue again. i noticed that this is also present in gnote. yeah this is sgs2 section but i havent found any fix yet.
images here are from s2.
what's surprising is that lumia 900 and 800 have this issue. common denominator: amoled.
Have it Note
Sorry, i know im on the wrong forum (or i have the wrong phone)...
I have been searching for a fix on this issue. It is also present on my galaxy Note. Those lines are irritating, most of the time when im indoor and with so many fluorescent lights around the camera lines appear.
Hope samsung get to notice it and give us solutions.
here's another

Is there a camera.apk around that can let you adjust the refresh rate of the Vibrant? It annoys me everytime when I'm shooting under low light condition with fluorescent light as there will be lines skipping across the camera picture...

It happened to me too once, I think it depends on the electricity frequency,
that may vary at different countries.
It's because you installed a ffc. Did you read any of the threads pertaining to the hardware mod you did? Wow. it is a very well known issue with the ffc

I did not install a FFC neither do I own one
If the camera is working correctly, and you suffer from this, one of the reason can be because of old style florescent lighting. It creates a rf that can cause this. Or, the camera mod could be defective. Or, using a ffc ehich uses a different freq format

Ffc banding does not look like that. Its worse
Sent from my SGH-T959 using XDA App
I believe that banding is caused by inconsistent power the fluorescent fixture.
I work in video and see this stuff frequently when the light isn't getting the correct power from the ballast.
That'd be my guess. Banding especially bad if florescent is on a dimmer.
My "fix" is to change the fixture or use a different light source.
So far it's worked every time.
Just my guess. Willing to admit I may be wrong.
Good luck!
It is because of the electro magnetic waves emitted by some lights and most older CRT TVs you know the big glass heavy ones.
strange because all of my pics are low light leveled because it has no flash but that looks like how the light is emmitting from its source and the camera is just picking it up. have you tried replicating the same issue under different light sources?

You can tweak the "white balance" setting and cure this easily.
Tried out every preset in the white balance setting but none of them seems to solve the problem... anyway it's not my camera's fault, I'm having the same problem with my EOS 500D.
Thread moved to Q&A.

Clean the lens, make sure you have good lighting as well.
Sent from my thunderstick
"clean the lense" - my first thought. grainy regardless of lighting condition but not as grainy outside in natural sunlight.
Rule out the rom, 1.8.6 is mint for me.
Sent from my ADR6400L using Tapatalk
I've noticed pictures are grainy on any rom for the TB and on the Incredible. It seems to happen most when you do not have enough natural light or when you are zooming. Phones do not have optical zoom they have digital zoom and there is a difference. I think digital just adds more pixels where as optical actually magnifies.
I took this one zoomed about 3/4 of the way in today in bright sunlight using BaMF 1.8.6 Remixed. It's the only picture I've taken so far since flashing the rom though.

yeah just wish my pictures werent so grainy
Digital zoom is pretty much useless - its equivalent to just cropping the photo. The graininess I think you're referring to is noise, rather than pixelation. You get noise when the total amount of light that hits the sensor is low, and with the tiny sensor on the TB (and most phones in general), this is impossible to avoid in many cases.
I do remember talk with some GB roms a while back about overclocking to 1.4 GHz for better camera performance. Maybe this would help? I can't imagine it would hurt...
Please refer to the picture below. Do you spot any abnormalities with my SAMOLED+ display? The yellow tint is gone after flashing to 2.3.5, but the area in the lower left is still showing a lighter tone--like a right triangle; so does a small area on the upper left. Also, the brightness (as I've noticed in other S2's) is not evenly distributed across the screen. These problems are hardly visible in normal use, but it becomes visible in grey backgrounds, and notifications area, and lowest brightness in web browser. Please let me know, thanks.

so, what do you all think? Please let me know thank you.
Mine looks exactly like that: triangle in bottom left, splotch in top right, and whole left seems a little dimmer than the rest. I haven't installed any updates & bought mine in South Africa; where did you get yours? I was honestly under the impression that AMOLED was the technology to go for, but now I'm not so sure anymore.
At first I was going to ignore the lighting defects and the pink tint in the center of camera images as there aren't that severe, but now I've found my phone's earpiece probably has a problem too. It makes a crackly noise during calls that sounds like something's loose in the speaker, so I reckon it's time to send this one back...
Update: I got mine replaced today due to the speaker problem, and the new one has neither the triangle nor the splotch. It is still darker down the left side of the screen though, maybe even a bit more so than on the old one...
I had exactly the same issues (well, not exactly as mine were worse). I had to replace it twice. Now I have one without this issues, no yellowish border and little to no banding.
The guys at the service told me that if there is any problem now, I can get a new phone right away, but considering how many people have display problems, I would rather repair this one. It's display is suspiciously perfect...

I got a replacement phone because the headset speaker died on my original one. I don't remember having this issue on the original phone. Can you guys take a picture of a white wall or ceiling in medium light and see if you have this problem. Otherwise I might have to see about another exchange.
Also, it seems that this has been a problem since the i9100 was introduced but I don't remember it before.

that's a light issue, not a camera issue. turn your flash on. besides, when is there ever a time that I need a picture of the ceiling?
(by the way, I checked this on 3 phones, the ones in my signature, and it does it on all 3 phones. Then I turn on my flash on the gs2 (since the other ones don't have a flash) and it goes away. in order not to get it without your flash, you have to be in more natural sunlight)
You've never taken a picture of something white before?
The ceiling is just an easy example.

I have, but if it's outside I don't get this red spot. And if it's inside, I don't get it either if I use the flash. I don't see that as a bug in the camera. My wife is a photographer. This is coming from her. It's the light.
---------- Post added at 10:51 AM ---------- Previous post was at 10:39 AM ----------
I also just took some pictures of things around the house that are on a white background. like pictures on our wall. I took some with flash, and some without. Now it appears that this red spot for me only shows up if the picture is completely white and I don't use the flash. If anything else is in the picture, it's gone - with or without the flash. Seems like a non-issue to me.
Read up on how to do a white balance for your camera.
As you go further out from the optical center of the camera, the angle which the light makes with the normal to the detector increases. This in turn means that, toward the edges, there's more chance that a light ray will travel through more than one of the colour filters, resulting in a color shift at the edges.
Here, it looks as though the camera white-balance has fixed a colour shift around the edges, at the expense of the center shifted to pink.
Phrases to google if you're interested: "pixel crosstalk", "bayer filter", CFA.
All smaller imagers are prone to this; they're simply too short for the optics to be close to telecentric (i.e. all rays hit detector at 90°). In a scene where there's a better range of colour and lighting, you likely wouldn't notice any problem at all. If you do, then cell-phone cameras aren't for you

Hi guys,
I've seen a serious bug with my White AT&T 920, and I'm about to send it back as defective, but I wanted to see if anybody else was seeing this error as well.
Basically, when I'm holding down the camera-shutter button halfway to allow for focus, the Optical Image Stabilization kicks in, and the image on the screen wobbles left and right. When I press the shutter all the way, the image is far from stabilized. Most of the time, the image is caught in motion-blur. Occasionally, the image is relatively sharp, but that's pretty rare.

And, yes - I was holding the camera as still as I could, elbows on the table, and squeezed the shutter slowly. Images like the one above are way more common than really sharp images. I can't keep this thing if this is what I should expect. So, defective phone?
Defective. I haven't gotten a picture even close to that, ever.

Yeah I would be using the warranty and getting that fixed or taking it back for a refund/replacement. Never had a problem like that on my phone.
Wow! Something is definetly wrong friend.

LOL! That thing is surely defected!
Replacement works great
I got the replacement from Amazonwireless today. First thing I did after powering it up was snap a picture. Crisp and clear! Thanks for the feedback, guys! Glad it was just a bad phone.:highfive:
Mine did it once after my factory reset. But the picture is not as bad as this one. Soft reset and back to normal. But the picture is not as clear and sharp as shown on those websites. Trying to replace now. Unfortunately, mine is cyan and is really hard to get a replacement.
