Possible production fault - Sawdust or cuttings behind display

Hello everyone,
when I got my SGS3 I was very excited. However, I noticed a possible production fault with the display, and I kindly ask any other SGS3 owner to check, whether this affects your phone as well.
Here is what's wrong:
When the you are in a dark environment (e.g. in your bedroom, reading in bed with your lights out - that's when I noticed it) and display a black image (most conveniently displayed with a display test app for example Screen Test - no outside links allowed for me, yet. Just look for it in the play store. It needs no rights and should have no strings attached ;-)).
Once your eyes have adjusted to the darker environment light, you will notice, two things:
a) the 'black' of the SGS3 is - by far - not as black as it was back on the SGS2. It looks much more greyish to me, as you see somehow kind of a back lighting. Don't know why you can see this, as I always thought AMOLED does not need such a thing, but anyway.
but much more importantly:
b) you see (at least that's what can be seen on my phone) little black (they are really black, in contrast to the display) 'snakelike' or 'wormlike' formed rubbish behind the display, which looks to me like sawdust or cuttings. Definitely a fault from production, though.
As I am not equipped with a good camera I am unfortunately not able to provide any photos (remember, it has to be dark in order to see 'through' the screen).
Can anyone confirm he has - or hopefully for you - has not these kind of problems?
The only good thing is, that the 'worms' are only visible in very rare circumstances. But now that I know that they are there, I always look out for them. And that is really annoying .

Like this?

If yes then you're not alone everything related should be in this thread. If something else, try to snatch a picture of it or reproduce it in Photoshop

Thanks, exactly like that. Didn't find it with the search function though. Thread can be closed, I guess

Cuz you're using the wrong terminology.
Those are often referred to around here as "blobs".
Skyrocket and Hercules (both GSII) are full of them.
But when ICS leaked for Skyrocket, it made the dark grey more black and it became harder to see the blobs, though they are obviously still there.
It never bothers me. But when I got a warranty replacement phone for a different issue, I noticed it had a lot less blobs on it than the first phone did.

Note 4 camera: Light pink spot under certain condition! How about yours?

I'm using Note 4 Duos N9106W. Its camera is not perfect but ok.
Here the problem of my friends. Some of them face this problem with N910C model. How about you?
Condition: daylight and indoor!

It is well known problem of Samsungs, starting from Galaxy S II if I remember correctly.
It is hardware issue, difficult to remove due to lens build.

I've been in Sonoma this week for a wedding. I've taken over 250 pictures in every possible lighting condition. I've been nothing but impressed with the camera. Really low light isn't great but it's better than other Samsung phones. Low light can still get you some impressive results.
Macro shots are impressive too.
I'm sorry you're having an issue but it's definitely not universal.

It is visible in plain scene mostly, maybe you can't see such effect. Conditions must be met ^^

I'll check the next time I find the need to shoot a white wall in a dimly lit room. I don't participate in threads that require replicating conditions I'll never or rarely face to create a problem. It's kind of a 'If a tree falls in the forest and no one is around to hear it does it make a sound'? thing. If I'm not in the forest I don't care.

Weird artifacts and camera server failed
Hi,
Is there anyone who saw image overflow of bright areas like this before?

Color convergence issues

Hi all,
I've had my 6p for almost two weeks and tomorrow is my last day to return it. They will not extend buyer's remorse to a replacement unit so before tomorrow I need to decide if the issue I have is specific to my unit (get a replacement) or related to the AMOLED panel used on this phone (cancel).
The issue is that colors seem not to converge correctly, just like old CRT screens would. This is most noticeable on high contrast borders such as black text on light backgrounds, which my brain interprets as embossed text rather than nice flat text. Below is a zoomed in example showing this issue, upper borders are reddish/darker and lower ones are greenish/bright.

Anyone else seeing this? my friend's S5 has a similar thing but way less noticeable and i could probably live with it, whereas my 6p is probably too much. Yes this is my first AMOLED.
Thoughts? thanks!

You are joking? Right?
That image is blown up how much??

400%. Otherwise you wouldn't see it on a forum, but real life you can see it with no need to zoom

Display uniformity

hi all, I noticed that the screen of my 6t is not uniform ... in a dark room with gray or similar colors in low brightness is lighter on the left while on the right is darker. You can check it with the OLED TEST application , if you put gray and lower the brightness.second you have to do it replace? I have read that the oled screens have this problem almost all and it would be lucky to find one without flaws.

Amoled screens are always a lottery unfortunately. You may get lucky and get a good one or you may get unlucky and get what you got. You can try and exchange but it's not guaranteed they accept it as a fault unless it's really bad. If you are in the return window you can go that then and then by a new one. You might get a better one and you might get one that is worse. I got lucky with mine this time.
In the image it looks a little brighter in the middle but I can't really see that with my eyes it's the camera that's doing that.

Downloaded a grey image and opened it in Google Photos and zoomed into it and then tap the screen and statusbar will go away.

Dark line on display

My 9T display when there is low light, the brightness is set to low and the image I see on the display is darkish I can see a vertical line at the right side of the display, is this normal or should I return It?

multiple users reported similar issues with low brightness, some said it's a rom issue but to be sure, post a screenshot or something and wait for others to respond.

Exactly in the same place, I think it's a recurring problem on this model.

Replaced the phone and there is no line in the new one, you should return It.

I don't have something like that on mine. Looks like banding to me, like on TVs. It can happen, it's probably not important. Screens aren't perfectly uniform.

I will wait and replace the last days of its warranty.
