[Galaxy S II Q&A, Help & Troubleshooting] Cofalik:
Pink spot is a problem common to many phones. It is connected with small lenses size and white-balance. This said, it's going to be there always, yet it could be drastically minified by software/firmware. That's why sometimes chaning your balance mode can result in difference in visibility of pink spot. All SGS2 have pink spots, more or less visible.

I, HTC Magic user ATM, thought that I don't have pink spot on my lame Magic's camera ;), but after doing a test on white wall with low light condition I can say that pink spot exist on HTC Magic. Yet I have never ever before noticed it while doing normal photos with this phone, even when I took photos of sheets of paper (student's notes ;)).

For more info on this problem, search Google. You'll find articles describing this problem on many phones.

The problem also exists in lowend cameras.

So now you can cut discussions whether the problem exists and when/where/why does it happen. It just is, may be lessen by software updates. I guess you'll have to live with it, as any replacement for 99% won't give you a phone without pink spot.

The only question is if any ROM/Camera App/Update make significant change to pink spot visibility. The discussion should head in that direction.

Dunno mate, like i told u before:) but in my s2 the pink is only in camera mode not in every display screen

I copied a test photo to my Sony notebook with glare free display and it's as clearly visible as on the SGS2 itself.

On which external display did you test?

Hi everyone !!

I FOUND ANOTHER PROBLEM IN THE CAMERA, PLEASE TRY THIS!

Put your camera in NIGHT MODE and then go to a dark room with no light, or almost no light, or take a picture to the sky during night!! basically just point your camera (in night mode) to something dark or black and see if you notice a BLUE SPOT in the left corner of your screen!!??? (IT HAS TO BEE DURING NIGHT OR IN A DARK PLACE)

PLEASE, let me know if you notice something...

best wishes
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
Confirmed ... tested it a few minutes ago ... there is a small blueish violett triangle in the upper left corner, if in nightmode and this area's background is nearly black. As soon as the background in this area is a bit lighter, the triangle disapears ... tested with blue hour sky.

It can easily be tested by covering the lens with a black cloth ... no dark room needed ;)

PS: As soon as you switch off nightmode the blueish triangle is gone.
[Galaxy S II Q&A, Help & Troubleshooting] franciscomerc:
ahahaha thank you fo testing...

its funny to confirm these things...

but in video recording any of this problems exist, even the pink spot, at least to me. but in camera mode is noticeable... maybe they will fix it on 2.3.4 or so. anyway, im a perfeccionist myself and i think we shouldnt bother about this small things... afterall it is a general issue and it isnt noticeable at all in our common use.

have fun with your Galaxy's S 2!! best phone ever
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
Good point. Pink spot or not .... if I compare to my Asus Transformer ... that cam is horrible and nearly nobody complains about it. And though it's similar powerful hardware, it has problems with 1080p, only 720p plays smooth.

I think for a phone this cam is absolutely great and for serious photography we should use a real cam ... that's what I always did.

Nevertheless I hope by updates it gets even better. Yesterday I presented my father a print of a photo I took of him with the SGS2 and it looked as if it were taken with a real cam.

PS: When I was a child I had to watch TV on a B&W tube and nowadays even 720p isn't good enough :D
[Galaxy S II Q&A, Help & Troubleshooting] pradnesh:
Well, i have got a new galaxy S2 and i tried

with and without flash on a white background and also on grey background and a faint blue background.

And i cant really see a pink spot, niether in Image mode or Video mode.

my build is

GINGERBREAD.XWKF3

I live in India and thats the latest firmware we are allowed to update too.
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
Test it in pure, but low daylight. If other light sources like flash or bulbs / tubes are involved my pink spot disappears.
[Galaxy S II Q&A, Help & Troubleshooting] pradnesh:
well it wasnt like pure, but looking at what kind of backgrounds other saw the pink spot, i feel the one i tried on was better white. And it was 1pm where i live(India) when i took the pics and video.
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
But that is important, because most people have a pink spot ONLY in low daylight, not with different light sources like bulbs.
[Galaxy S II Q&A, Help & Troubleshooting] gil80:
There's a camera firmware upgrade in samsung apps under utilities.

I've used this upgrade but now the problem is reversed.

In order to counter the pink spot, you need to use green color which neutralizes pink.

so now the center of the frame is green and the rest is pink in relative perspective...

stupid people in samsung :)

It's a common issue and problem with SGS2... I don't know about other countries but in my region, S2 users are complaining daily about this.

I hope it's just a software issue and Samsung will work out an update very soon. Otherwise, it would be a big disappointment for this device.

Hey guyz, finally my SGS2 is back to ROCK!

I just got my 5th replacement unit, because they can't fix the low mic volume problem and the camera mechanism noise. It's defective and nothing can be done.

Now my SGS2 has a very clear mic volume during calls. No more shouting, screaming and complaining. Save my voice for longer quality business call. :D

This is what we call a useful phone~~~!

Sorry, but no hope for pink spot issue, still remaining the same.

yea I have this problem. I think more than 60% of the sii in my country have this problem... T.T
[Galaxy S II Q&A, Help & Troubleshooting] holyguyz:
Make sure you update/upgrade your camera firmware at Samsung Apps. Pink spot only available at indoor with low light environment. You shouldn't have the pink spot when using flash light. Tweak around with the brightness and set contrast to auto will helps. Cheers!
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
The pink spot has nothing to do with UV light ... I tested it with a UV blocking filter from my DSLR. It's just a matter of daylight white balance under low light.
[Galaxy S II Q&A, Help & Troubleshooting] gil80:
The pink spot occurs on galaxy s I9000 as well. I tested this issue with several phones and all of them have this pink spot.

BUT this isnt really pink... my guess it's rather purple, and here's my explenation.

As a professional DSLR photographer I've encountered purple spots with long exposures. Long exposures cause the camera sensor to heat up and that heat is than translates into purple spots.

I believe the source is the near distance from the phone CPU or other heat source inside the phone to the camera sensor which also low in quality build.

Therefore the only fix for this will be pure cosmetics by altering shifts of colors variations reflected in White Balance selections.

Purple/pink is countered with green. Lets hope samsung will fix this soon.

P.s. also apple had this problem
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
If that would be the case, the pink spot shouldn't occure, when the CPU is relatively cold, but it does even after the SGS2 was switched on after several hours being switched off before.

That's why I still believe in a reflection between protective glass and lens. This issue reminds me more of the hot spot problem in IR photography, than long exposures, where we mainly see sensor "bleeding" at the edges and not in the center.

On which DSLR did you see a pink spot phenomenon on long exposures?
[Galaxy S II Q&A, Help & Troubleshooting] @raj2010:
Hi all.

I got my samsung galaxy s2 (through T-mobile upgrade) last week and noticed the pink spot issue. I exchanged the phone...on receiving my new phone, this is the first thing that I checked...and was glad to find there was no pink spot but once the samsung updates were installed I noticed the pink spot again...and I have factory reset the phone but the pink spot still remains. By the way the camera firmware did not help at all in both cases.

I called Samsung to verify the issue and they advised me to apply the firmware (which I already had done), failing that the phone would have to go in for a repair - funny because the repair centre said there is nothing they can do about it.

Anyone with the pink spot problem...I would be greatful if you could remove the backcover and battery and post where your phone was made...Both of my phones state it was "made by samsung"...I was at an o2 shop discussing the problem with one of the advisors and he under the impresson that the phones that state "made by samsung in Korea" doesn't have this problem - he even showed me the display model which was fine - there was no pink spot.

I suggest that if you are returning the phone back to your network providers or samsung, please leave the pictures with pink marks on the phone - with a little note - for their attention since some of the advisors (even at samsung) find it strange that the phone has the tendancy to behave in such a way.

Anyway, I am now getting my third (and final) exchange next tuesday...will keep you guys uptodate.
[Galaxy S II Q&A, Help & Troubleshooting] MeanWoman:
My unit is made in korea but also exhibits this pink spot issue.
[Galaxy S II Q&A, Help & Troubleshooting] holyguyz:
Pink spot is an official issue for all SGS2 phone. Nothing can be done. Update your camera firmware and tweak around the brightness and the contrast will help reduce the pink spot.

Mine replaced with 5th unit still the same condition.
[Galaxy S II Q&A, Help & Troubleshooting] akirax:
With Cam FW Ver: TBEC28 there isn't pink spot. I tried a lot of SGSII.

With newer firmwares the pink spot appears.

But we can't downgrade camera firmware...

I don't have a pink spot, I have a greenish spot right in the center like you guys, but green instead of pink...

Anyone else has that problem ???
[Galaxy S II Q&A, Help & Troubleshooting] holyguyz:
Tested at home > pink spot.

Tested at retail shop > greenish spot.

I think the lightning at certain place produce different color of spot on SGS2 camera.
[Galaxy S II Q&A, Help & Troubleshooting] bossman74:
You sir are correct, I only noticed it at the retail store since the green was so noticeable.

Is this only a software issue ? Nothing related to hardware interference or temperature ?
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
In my opinion it is caused by a reflection between lens and protective glass. And the firmware eliminates the spot, which fails under certain lighting conditions.

It might be a solution, if an optician creates a new protective glass out of a high quality photo UV filter like the B+W UV 010 MRC, which is multi-coated on both sides.
[Galaxy S II Q&A, Help & Troubleshooting] give:
For any one that hasn't seen it the AnandTech review is excellent (loads of internal photos too). There's a page covering the camera that's worth a read. Turns out Samsung are using 2 different camera modules.

It would be great if we could find a way to get the SGSII to output which module is on board each device. Perhaps there is a link between module and pink spot issue?
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
As far as I can see, no. But there might be a link between module type and video frame rate issues?

I'm looking everywhere to get more info about why my S2 lags as hell when both recording, and than watching movies in 1080p. I tried using google, and xda but no luck, can anyone be so polite and give me direct link, or maybe some keywords? I'd like to read more about that and get rid of this. Maybe newest rooted stock rom will do? Also I flashed exynos 5.4 and it has volume+ app and dsp manager - both those apps doesn't work for me. On S1 I had some app with red android icon, that boosted my audio alot. I'd like to have that on S2, but no luck. Any help with that maybe? Sorry to OT.
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
If I remember it right, it was discussed in the camera firmware thread here at XDA.

So far there's no solution. Thank god, I don't have video problems.

There's an audio discussion too. I use Poweramp from the market, which does a nice job with the correct equalizer settings. Give the trial version a try. And be careful with bass boosting, which leads to clipping fast.

I have my Galaxy S2 since september 16. If I take a photo in low light conditions and using flash, a pink line appears all over the right edge.I have uploaded two photos so you can see it. I suppose this is not the Pink spot, because it is not a spot and it is not in the middle... but If I take a photo with good light this doesn't happen and no signal of the pink band on the edge on videos too...

Do you think this is the same like the pink spot?. Is it a hardware fault or software fault?, because with good light photos are perfect but this is a little bit annoying with the "night life" photos.

Should I take my phone to samsung technical service?.

Thank you very much

[Galaxy S II Q&A, Help & Troubleshooting] tonymy01:
That looks like simple flash bleed from the edge of the flash to the lense. Do you have a protective case or cover of some kind on the phone, it could be the brightness of the flash bouncing off the edge of the case and back into the lense.
[Galaxy S II Q&A, Help & Troubleshooting] SaReDnAL:
No, I am not using any protective case, only in the screen, so I guess this is some king of hadware failure on the flash?.I have some photos with low light conditions but white light where I dont have the problem :S
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
This reminds me of the sensor bleeding in long exposures (several minutes), I've seen in astro photos taken with a DSLR, where this problem is heat related.

Because we don't have such a long exposure here, where heat might play a role, I fear, it's a sensor defect. I don't have such issues in night shots.

It's definitely not related to the pink spot phenomenon discussed in this threat, where the spot is in the image center and mainly seen in daylight shots.

PS: Is the protective glass in front of the lens clean? Or where there fingerprints? It's hard to tell from the photos, because of the motion blure caused by the longer exposure.
[Galaxy S II Q&A, Help & Troubleshooting] SaReDnAL:
Then I will go to the technical service maybe they can get it fixed :P

Ok guys, I have gone to the Geek Squad technical support and they have told me that I'm gonna have my SGS2 camera replaced next week, but they told me maybe the problem is software related (firmware). When I purchased this phone the camera firmware that samsung released on august was already applied. Do you think it is possible that this "firmware" applied wrong?. Or this flash bleeding problem is hardware related? Remember that the photos are ok when no flash is needed, so I dont know what to think :S. Thank you very much!

[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
Maybe a small amount of sensors Samsung ordered for the S2 production were defective.
[Galaxy S II Q&A, Help & Troubleshooting] SaReDnAL:
So, although the problem becomes when the camera uses the flash, the problem might not be in the led (maybe is not straight and it is moved or something). I think the problem is in the shutter, it is not doing well the synchronization between the flash light and the shot. I will update you when I have my camera replaced next week, and If the problem persist my G2 will travel to samsung for a month. I hate not knowing anything about photography!

Maybe there's something wrong with the phone's camera housing, that allowes some light bleeding from the flash to the lens?

Or there's a whole cam module series with the same defect?

Very strange. Maybe try contacting Samsung support and ask them, if they know about this problem.
[Galaxy S II Q&A, Help & Troubleshooting] slkdk:
It is NOT the flash.

I have the same pink spot issue and can replicate the problems WITHOUT the flash.

I don't need to take any picture, just point the phone in cameramode at a white wall indoor. Easy to see on my phone.
[Galaxy S II Q&A, Help & Troubleshooting] tonymy01:
I think you have missed the point they are talking about, which is not pink spot, but the whole right edge if the photo has a pink line on it when the flash goes off in low light. Yes, pink spot is real, but they are referring to another issue that this person is getting, possibly from poor housing seal between lense and flash?
[Galaxy S II Q&A, Help & Troubleshooting] Aymara:
That's what I expect to be the reason, when I here, that a camera module exchange didn't solve the problem.

And yes, in this case it's NOT the typical pink spot phenomenon, we're talking about.

I could send it to the seller or Samsung for repairs/exchange, maybe the next S2 has a little less pink spot >.>
