Uneven backlight, greys mainly, Note20 Ultra - Samsung Galaxy Note 20 Ultra Questions & Answers

Anyone else noticed this? More noticeable on dark mode but also on light mode whenever you see grey backgrounds. Total blacks are fine, but anything grey looks very uneven from left to right, it's almost as if the light coming from the left is way brighter than on the right. I had a Tab S6 that had this problem, but never with my previous Note 10+.

Screen is brighter left and darker on right edge

Hi,
I have Galaxy S7 (international ver) for two days and I notice that the screen is slight brighter on left side. I notice that when I look at dark gray solid color on fullscreen. It's solid color but I can see slight gradient from right to left (from darker to brighter). Is that normal? Is it bad? What to do?
I can't take a picture of that because I doesn' have such a good camera to "see" (capture) that, can be seen only by naked eye.

light bleed.

just noticed my google pixel from verizon has serious light bleed on the top and bottom right corners. very noticeable on a black wallpaper or the ambient display screen. anyone else face this issue, defective lcd i suppose? :crying:

Light bleed comes from screens that are backlit by an LCD or LED. The Pixel uses an AMOLED screen, which does not use a backlight. Instead each pixel (of the screen) produces it's own light. Therefore, there can be no light bleed.
If you are seeing something resembling light bleed, I think you have a bigger problem that should be covered under warranty.
You should upload a picture so we can see what you are looking at.
im assuming it was a defective panel. so i got it swapped out today. new one is fine. amoled or not it seemed like light bleed to me on dark wallpapers.

Yeah, I figured there was a problem with the panel, glad they changed it out for you.

Its not typical backlight bleeding since as u said there is no backlight, but its the same thing that causes grey uniformity issues. Contrary to what people think amoled does not 'shut off' pixels when displaying black unless screen brightness is at a very low level. When checking the screen for uniformity with a grey backgrond my amoled screen has a yellowish tone in bottom left area and this same area wont display 'pure black' unless brightness slider is at a certain position.

Just got the S8 and the screen has a red tint (just like korea)

I have turned red off in colour balance, I have tried a different display formats and can't get rid of it. what's worse, is that at the endge of the screen it's a red GRADIENT so even if I get it close to white, it will never be even

Is this while viewing straight on or at angle?
This is crap. Samsung will ever get their screens right?
Pics please
Mine has a very slight red/pink tint on the right hand edge as you look at it straight on. Goes away when you tint it to an angle. Something obviously isn't as it should be but it's almost like the curved edge is causing it. My S6 Edge had nothing like it though.

agreed, a couple of others on another forum I post on have the same issue, looking straight on doesn't help because of that graident around the phone.

Shadows on display

Guys but also you at the bottom of the display you see black halos?
I means like shadows where there is the back button, and down bar.Where the black stripe stops.
On watssapp, facebook, messenger and chrome this shadow it looks better, on white backgrounds.
I hope to be paranoid, but to all of whom I asked said yes, it can be seen :crying:
Thank you
I think you're seeing the LEDs from an LED edge lit display. The same issue that causes a "yellow" tint. The backlights diffusers aren't perfect.

Not all, only on the bottom and the color it's grey, like vertical strips.

I know what you're describing. I've seen it on one. I'm just telling you what I think is causing it.

Question Reddish/pinkish screen on Galaxy S22 Ultra when tilted

I bought a Galaxy S22 Ultra and noticed that when I tilt it from the bottom, if there is a white image, the screen tends to be reddish/pinkish.
I am familiar with amoled screens and I know that if you tilt the phone from top to bottom it tends to green, but from bottom to top I've never seen a screen that turned red. It is very annoying.
I have compared it with the Galaxy S22+ and Galaxy S21+ of friends but I have not noticed this problem.
I went to a shop today and compared it to the exposed Galaxy S22 Ultra and it had the same problem.
I am undecided whether to replace it, I don't want to be without a phone for 1 week, Has anyone else noticed similar problems?
I leave you some images for verification with your phone: https://drive.google.com/drive/folders/112UppJ-NFURNfnRR4iMA5qGd4-3AXrZd
P.S. I know that when tilted from top to bottom a green tint is shown (as in this photo): https://drive.google.com/file/d/11J8BYws_zmsqgGd4zGTTIIJTaiWN6f-g/view?usp=drivesdk
I know that from this angle it is normal. I mean if it is tilted backwards, that is, from the bottom to up
Yes! I saw a green tint when going from top to bottom but not any pinkish tint.

On the contrary? if you tilt it from the bottom up, don't you see a pink tint? Which phone do you have?
S22 ultra SM-S908E, no pink tint from any angle. I even increased brightness to max to see it better. It stays fairly white from left to right, right to left and bottom to top. Green tint is visible from top to bottom though..
So the green tint when viewing from top to bottom is normal? I'm not very familiar with Amoled screen. I hope mine is not faulty. I will go to Best Buy tomorrow to check on their display units.
Green tint is visible from top to bottom on my t-mobile SM980U device but I only saw it when I looked for it after reading about it here. I doubt I will again after this. Absolutely no pink tint though.
