I've just noticed a white pixel when i use camera in low light contition. Is it normal for this device?It's not a lcd screen defect because if i zoom the white pixel moves itself. If u want to test it simply cover the lens and see the image on the screen
This is normal. Many people have reported this. I knew about 1 dead black pixel. Having just tried pitch black camera I found 2 white dead pixels. Nothing to worry about, apparently the majority of devices have them.

Ah ok, thanks! Iwas going to send it back ! However the pixel appear after few seconds and not just when i open camera. I notice it is barely blinking...
However lcd is perfect...
The white pixel appear only form 400 to 1600 iso
Anyone noticed this issue?
i noticed it too, a green pixel,that is visible or not depending on the visual angle.. absolutely normal for that kind of screen

It isn't display issue it appears only in camera mode above 400 ISO and it's noticeable in very low light conditions
Hi,
I have an odd problem. Running CM10.2 stable.
If I try to take a photo of a subject with bright background (ie: sky in the top half of the photo), even if I focus on the subject, the subject will be very dark and the sky will have a correct exposure. If I put the subject in front of a building, it's fine.
On my Nexus 4, if I focus on the subject, it will adjust the compensation to have the subject properly illuminated (and sky will be almost white), but if I focus on the sky, then it will have the correct exposure for the sky and subject will be dark.
Any idea what's causing this?
Thanks.
This seems to happen on stock factory ROM as well.
Could someone please do a test to see if it's isolated on this phone or if it's a bug in the driver/hardware?
A light bulb is enough to be in the picture, if you focus on the bulb, the rest of the photo should be black and the light bulb clearly seen.
If you focus on the wall, the wall should now be visible and the area surrounding the lightbulb should be almost white (over exposed).
Thank you.
Hi
When i took photos in very Dark place on Pro mode with Below settings there is some white Dots(Spots) on picture(maybe Like Hot pixel):
1- set exposure on 10 (sec)
2- set iso on 800
The spots place is fixed on all photos in this condition...
Is that nature?!
-The Attached pictures is zoomed in.
You probably already have done it, but, are sure your lenses are perfectly clean, I mean, cleaned with a good clening liquid and a proper cleaning cloth?

If lenses are clean, and it really is a pitch black place, and you had the flash off, and the dots stay in same place on every photo, then it has to be
1) micro scratches (from sand / grit)
2) Dust. They could be dust settling on your freshly cleaned lens (static) - I know if I clean my lenses with kitchen roll, it becomes a dust-fest
3) Fault in CMOS sensor. Though I wouldnt have thought the fault would be white dots, as white is after all ALL colours in the visible spectrum, maybe should be red or magenta maybe, but not white. There are different light sensors for each colour If my limited understanding is anything like correct, therefore, for white to be displayed, red/green/blue sensors at that very same point would ALL have to be faulty. Therefore, to me, a CMOS sensor fault seems unlikely.
4) Dust seal compromised. Unless you have had back off it, this shouldnt be so. Return under warranty if knox is intact.
Good luck.

Are you have Note 8?
I tested two other Note 8s and there was same problem too.
My phone is new and there is no any dust or scratch...
The lense is clean and white dots place is fixed in any photos.
Just test it with take picture in Pro mode with 10 exposure and iso 800 in very dark places without any light. Probable you can see this white dots when zoom in the photo too.

Yes, lens is clean.
I tested two other Note 8s and same problem exist.
Please just set the setting like image below and test it:

OK I'll bite. As much as I didn't want to I checked mine. I do have spots but they are only in the lower left (lower right on these pics because of the rotation) and vary from dots to lines. I suspect it's a limitation of the aperture seeing it only happens with a 10 second exposure and 10 is it's set limit. The first pic was in a dark closet and the second is with a thick cloth over the lens. It's not a deal breaker in my case because I rarely if ever would set the exposure to 10 seconds, I'm mainly a point and shoot person.

I think you didn't set the ISO to 800 in these attached pictures, yes?!

I did. Iso at 800 and exposure at 10 sec. Any other exposure other than 10 seconds and the spots are gone for me.
I took this picture in iso 800 and exposure 10, you can see the white spots clearly:

Yup, it looks like stars. Hopefully others will check as well.
My Sony dashcam does the same thing.

I tested the cam at 10 sec exposure and ISO 800, and yes, there are star like spots, but only visible when enlarging the picture, I had seen this happening with othe phones and cameras at no extreme seetings, that is, not entire seconds of exposure, no totally black pitch ambient, In fact I think that this happening only at 10 sec of exposure is not a big deal, when these dots appear, it is in a situation that almost nothing will be captured in the photo, if something appers in the photo, means there is enough light to be registered, and then, you would not notice the dots, as I most surely will not take pictures in these conditions, I am not worried, I take standard photos all the time
It's normal
Okay. Just tested mine. Same thing. However I do have to mention that I frequently take nighttime photos for astrophotography and typically you wouldn't want such a high ISO on a long exposure because it introduces noise to the photo. And 800 is the highest ISO setting that the Note 8 has. Any camera will do this to you. The long exposure will collect enough light by itself to negate the need for such a high ISO. Not really a defect in the camera, just the process of taking the picture.
While on holiday, quite often at the beach, when switching on the camera, all I got was a bright white screen (like the lenses couldn't cope with the bright light)
After I put my hand over the lenses (to create darkness) and removed my hand, they were able to see an image.
Anyone else experienced that?
While I was watching a video, I noticed a permanent yellow tint on top of my screen (where signal/time/wifi are located, in those spots). The yellow tint is permanent and it's more noticeable when the brightness is on max, especially on white screens), it doesn't go away nor it changes (for example on yellow tint, i can see some past 'time' and notifications). I am not sure how to explain it better. The phone never fell down, nor It has any damages. I have it for a year and I never had any issues.
Anyone with the same problem? I mean it's something terrible but it sometimes it's annoying.
I also wanna say, if I take a screenshot of my screen, and then check that screen on my PC for example, I don't see the yellow tint.
That's exactly how it looks: https://cdn57.androidauthority.net/...17/05/aa-imgur-galaxy-s8-burn-in-1200x675.jpg
Screen burn in, I imagine? Plus I can see my Google keyboard clearly on a fully blue screen. I wonder if the problem is just the screen or the frame underneath the screen as well. I guess it's not fixable unless you replace it...
