Hey guys, I've never posted here, I mostly just lurk and try to learn things.
My question is a bit difficult to explain but I'll try my best. Do me a favor and take a photo while completely covering the camera lens, then view the photo in the gallery. Make sure youre in a dark room and viewing the photo in full screen, wait a second for the back and task manager buttons to turn off as well.
Is your picture completely black or are the outside edges and corners fuzzy and white almost?
My previous phones are Galaxy S1, 2, 3 and 4 along with the Note 3 (which I miss :/ ) never had a problem like this, I do believe some GS2s had a similar problem with the screen being spotty in black images.
thanks.

Hello there, I did a test for you on mine, when i was in my room with my lights on but completely covered the lens and mine came out fuzzy. It seems that the s5 camera is very powerful picking up the slightest bit of light !
Then I turned off the lights in my room and did the same test, this time it was pitch black.
Did you try turning all your lights off in your room?
Thanks for your input, my initial test was in a room with the lights off. Looks so bad :/

I noticed that with my camera too. The exact same thing happens to me too when I cover the camera, in both lighted and unlighted rooms. But I'm pretty sure it's normal. When your ISO is on auto, you'll notice that the camera turns up the ISO past what you can manually set it at (800). So since they're bumping up the ISO so high (probably ~1600 in dark areas), there's going to be considerable amounts of noise, even with very low light.
You can see for yourself that if you compare auto ISO and ISO 800 in a dark room, the latter will be much more pitch black like you expect it to be.

Auto WB issue! Video Link showing dynamic changing in light sources: http://www.youtube.com/watch?v=0F0x1wkt5EU
This ones to all you SGS2 owners...
Today whilst takin' pics of my son, i noticed whilst pointing the camera down at my cream coloured carpet a pink hue was clearly visible in the centre of the shot. I took a snap and the hue was on definitely there... this was during the day time with only ambient light from my large bay windows...
slowly panning up across the room towards the window it seems to fade away, but directly at the light surface its unmissable...
I double checked the shot on my partners DHD, her shot was completely pink, very poor camera!!
Anyone elses S2 suffering from this? a quick google search shows this has also been an issue on other handsets such as the Nexus One and Samsung Focus...
Cheers,
Dickie
This is very important.
Can you make some photos and upload it?
if someone more have the classic tint pink of cheap cameras like other HTCs I am going to cancel my order inmediately.
Here are some untouched Macro shots taken in my backyard in fading light with the Galaxy S II, was a bit windy so the flowers kept moving:

I don't know of any sansung Focus.
Can anyone shoot to white walls or cloudy sky?
It is the faster way to see if the camera have the pink tint.

The shot! 8mp default settings

Dickie
just to add, this has been the only time ive noticed this issue, shots taken across the room show no visible signs of this, just the straight shot...
tbh, with the quality of all the other shots ive taken, its not a deal breaker for me, this phone still blows away any other ive used, and i don't find blank white walls/carpets interesting enough to take photos of...
Dickie
That sure looks like something I read about some HTC phone a while back. I'll need to check my phone to see. I wonder if it's software or hardware related.
after some testing i believe this is a software issue, specifically with the AUTO White Balance setting, as i point it to the cloudy sky out the window it looks perfect and when switched to incandescent it goes away!!
like i said before, i don't make a habit of shooting my carpet or my white walls very often!
Dickie
EDIT: when switched to Daylight mode, it also goes away, although it makes the carpet look orange for obvious reasons... Definitely a White Balance issue, the lighting and colour of the carpet requires the correct setting as opposed to the Auto mode, outside or with good lighting the Auto setting is fine! as far as i'm concerned, panic over! lol

That it isn't a white balance issue, it is a hardware problem. HTC got the same problems on a lot of devices before, and they tried to hide it tweaking the colors, but that doesnt solve the real problem.
If I were you I will return the phone for another one.

then why when i switch to the correct WB setting for the lighting i'm in does the issue disappear?? the issue only arrises in Auto mode under certain lighting conditions. just took a white sheet outside on Auto - No issue!
Dickie
Maybe in a non-auto mode they know the color temperature that software will apply to the image and then they can tweak the pink tint of the image, but with an auto mode that changes dinamically the color grade they cant adjust the pink tint.
I really dont know, but all of the pink tints problems in all other phones are hardware related issues, I don't know why this is going to be different.
i get exactly what you are saying, but i'm only going by what i'm working out on my device...
at the end of the day, like i said before, its not a deal breaker for me, and ive not had a single issue with it in other lighting conditions...
Also, ive just walked around my room allowing the camera to adjust dynamically, and it does disappear!! i have a standing lamp on, a small window on the opposite wall, and the large bay window at the front of the room, the pink hue is not permanent and is just the Auto WB not being perfect.
Its even visible on video, so i'll upload a vid of the pink disappearing as i walk around the room and the light changes dynamically! Auto WB issue for sure!!
Dickie
Just registered after seeing this...
A pink hue like you describe usually means infrared contamination, and happens on any camera to varying degree. Some black clothing in direct sunlight suffers the most.
Edit: Extreme Example: vimeo (dot) com/5637250
Regards, Matt
I'm just uploading a video to Youtube 720p - WB AUTO
You can clearly see the pink hue fading in and out as the phone auto adjusts to the varying lighting in my home, namely Incandescent light fittings, Fluorecent light fittings and daylight outside.
If i set the camera to a setting for one of those lighting conditions specifically, there is no issue in said condition.
I will update this post when its uploaded with the link - THIS IS NOT A PERMANENT HUE CAUSED BY HARDWARE - ITS SOFTWARE STRUGGLING WITH THE LIGHTING CONDITION!! - phew!!
Dickie
EDIT: the hue becomes very apparent after pointing the camera and any of the light sources directly then quickly moving to a white surface, it then gradually adjusts away...

I doubt Samsung will use the low quality camera sensor that HTC uses buddy.

not sure its the same buddy, it appears in the centre of the image and fades out, i'm 100% certain that this issue is WB/lighting condition related, 10mins and the link will be up if your interested...

I can't agree more there, you should have seen the same shot on the Desire HD, the carpet was entirely pink!! not just a spot in the middle..
Dickie
BTW I just checked my phone and observed the same situation as described by Dickie. After checking for myself I'm certain it's software related. They may need to tweak their auto white balance algorithm.

Hello XDA,
I've searched around for this problem a bit, and it seems this issue hasn't been brought up anywhere. If it has, then I apologize.
The S2 has an awesome display with great colors, blacks included, but I noticed this issue one night when I was watching a film on my S2. When the display is showing black/dark images you can clearly see what appears to be glue smudges all over the screen, especially along the rims. It is only noticeable when there's little to no other light in the surrounding environement. Increasing brightness seem to worsen the problem.
It is hard to describe and very difficult to capture on camera but I made an attempt. I can't post links yet it seems but here's an imageshack url:
img842.imageshack.us/img842/5420/blotches.jpg
The image was taken with a Canon 450D with 20 sec exposure (hard to focus when it's that dark I'll tell you). Edited slightly in photoshop to cut down the size.
Here you can see the general color of the screen (gray-ish) and some of the blotches of (what I'm guessing is) glue in the back. If I had to guess I suspect the blotches might come from the capacitive touch layer of the screen. Is this an issue or is it to be expected on phones like these? It's not a major problem but it's actually quite annoying when you're watching a film/youtube clip/playing a generally dark game or whatever. Should I return my device? I've used it for just about a week and a half.
Thanks in advance for any help.
i have this too, its the AMOLED display. you can turn the screen off and on and you'll see it go off n on. not the sgs, but amoleds generally. my omnia HD had this too (1st gen AMOLED)
the blacks are not 100% black i say
Im having this too, nothing to worry about this as it doesnt disturb the beautiful display of this mobile.
I just got my refurbed Tab yesterday. I've owned many tablets over the last year, but I've never experienced a soft kind of glowing effect on dark parts of the screen (like in a dark scene in a video, or even the bottom control bar) when viewed at any angle at all. The image almost becomes difficult to see unless you're looking straight ahead. I only notice this when there's little to no ambient light in the room (which is when 90% of my tablet usage is- reading or watching a movie in bed).
I compared with my touchpad in the same scenario and while there was a *very* slight glow, it wasn't nearly as bad as on the gt 10.1.
I found next to nothing on Google about this. Does anyone else get this, or do I possibly have a bad refurb? It's a shame because I'm completely in love with it otherwise...

Is it coming from the sides? If so, it's LCD screen bleed. It unfortunately happens with backlit LCD panels. It doesn't appear to be too common with the Tab as I haven't seen it mentioned before. I'd send it in for repair while it's under warranty. They changed the screen design in October and you'll get it back with a better display then it has currently.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
No, it's not from the sides. There's no bleeding. It's on the screen itself. It's almost like kind of a ghostly white glow on top of the dark colors on the screen. A shimmering effect, maybe? I'm not sure how else to describe it.

if possbile post the screenshot.
Hm. I guess i'm not explaining it well.
While it is on the screen itself, it's only when you tilt the device to the viewing angle isn't straight on.
Here's a thread from a different forum discussing it:
http://hardforum.com/showthread.php?t=1546595
There are also youtube videos showing it, like this one:
http://youtu.be/-eA2IjlotJU
I just compared my G-Tab with an ASUS Transformer, and it was still there on the Transformer, but not as bad as the G-Tab.
Some time ago I noticed that, in some very special situations, like under direct and strong artificial/sun light and a particular angle, I'm able to see a couple of small, very faint spots, kinda similar to those left by dried moisture (like a drop of water) underneath the screen. At first I though it was my bad for putting on a wet screen protector, but just the other day I had a look at the device of a friend of mine (no protector wahtsoever), and looking closely I found similar spots, just not two but a single and bigger one. This got me a bit puzzled, so I decided to take a look at a third device, this time a demo unit in a shop, and guess what? Also that one had a similar mark right in the middle of the screen.
Now, not that this bothers me much, since you can't actually see it unless you really try (I can't even catch it with a camera), but I'd love to know from you guys if this is a common "flaw" or I just happened to grab a "flawed" handful of devices...
Yup, I have these dark patches. You can see them sometimes if you look at a particular angle when the phone is booting up. I can't see them any other time though
I can see dark patches when the screen is dimmed, especially at night, I can't see it any other times, Nokia returned it to me because they couldn't see it. So they asked to send it in again, it took them ten days to just flash a ROM....I was pissed as it is.
When the Display is off I can sometimes see some "blacker" areas on the screen. According to Nokia These are splices where the glass is somehow glued to the display.
Thank you guys, at least I feel a little better about it now...anyway it still puzzles me how this is the first device I own in years with this kind of issue, and I really had many, both resistive and capacitive, with or without gorilla and even made of plastic. I mean this isn't really a flaw, but knowing it's there annoys me. Damn, maybe I should really just stop being so OCD with my devices, it hurts

I still would class it as a fault, it makes my eyes burn.
Are you speaking about the spots which are visible in the dark if the screen is black?
I saw them when I did my screen black in diagnostics app - lcd test.
So I took a picture of "black" screen with long exposure (iso 400, 30 seconds exposure) and show it in nokia care service. Week after I got new display

Actually those aren't really "spots", it's some sort of light leak that all amoled devices have when displaying plain black: even if all the leds are supposed to be off there's still some electricity going through them. I had that on all of my amoled devices, on my Desire, on my SGS2 and on my Omnia W as well, it doesn't look that great but it's fine I guess. Weird that you still managed to get the screen replaced, maybe your unit actually had some excessive light leak.
Here I'm talking about a different thing, given that you have them you should be able to see those spots I described even with the device completely off if you keep it under a strong light and at the right angle.

Can't reproduce that. I look closely but see nothing special.
Though, as Russian proverb says - the less you know the stronger you sleep
Here is a picture of screen with the spots I was posting about.
So, if anyone have scratched screen as I had, it is a good reason to get repair
PS note that picture was taken with long exposure. Actually my eyes need to get used to darkness to see glow.

Yeah that's it, the good old light leak
Anyway the picture you took being overexposed gives the impression of a huge issue, so I guess they replaced the screen right after looking at that, even tho in normal darkness conditions it's definitely not so annoying. Good for you that you managed to get it replaced anyway
lol a 30 second exposure will bring out the worst of the display. I can understand they replaced it after showing that image that sort of tricks them because it will never be even close to that visible to the naked eye.
Completely normal for AMOLED displays.
I think I have a duff camera on my new Z2, took some photos of a off white coloured box and a wooden desk and green horizontal banding on the photos. I also noticed what looks to be an oscillation in brightness when previewing a picture before taking the photo.
Has anyone else noticed this behaviour? I have requested a replacement as this is not something I have seen before and don't think it should be doing this.
The other query is about image stabilisation, stabilisation can be enabled in manual mode but cannot when using the superior auto mode, is this correct?
Thanks
Mine performs great. I'd ask for a replacement because it seems like a defect.
Fluorescent tube lighting by any chance?

There was fluorescent lighting but it didn't affect an iphone taking the exact same picture, my old Galaxy S3 wasn't affected by fluorescent lights either. If the Z2 is affected that badly by lights in the ceiling it is pretty crap and will definitely be getting a refund.
We will see if the replacement is any better but I don't have a huge amount of confidence that it will be.

Should be an attachment showing the banding on the photograph.
Point any digital camera near a fluorescent light and you'll see why I asked that. It's not constant light, they pulse and taking photos of white objects bounces the pulsing back to the camera, iphones may be different due to a rolling shutter what ever that means but I know for a fact galaxy s3 did the same because I had two of them and I spent a long time in my flourescently lit shed trying to take photos of white snakes.
Look here and read the section on disadvantages and sub section on flicker effect.
