Haven't got that problem but sounds like bleed.

For me, the screen is one of the very few things on this phone that I am happy with. So, it seems limited to some batches maybe.

Rainbow Effect on Screen

After being in my pocket for some time, there is a rainbow effect on the screen. I can change the location of this effect if I push elsewhere on the screen; however, it seems to concentrate itself right in the center. It has no ill-effect on the touch screen but it is visible under certain angles when the screen is on. I am using the screen protector that came with it. After some time being out of my pocket it dissipates and looks normal.
Anyone else experience anything like this?

Yeah, I have.. I haven't noticed it's touch sensitive, but I've seen the problem while rebooting and also randomly while using the phone.. And it seems like for me the screen gets progressively worse and starts losing all contrast and fades to white. A reboot always fixes it.
My guess is something in the video drivers flips out. But the first time I saw it I thought I had a hardware problem because I found it that way in the morning out of the blue, but I guess it had started doing it 'itself' overnight or something.

I dont think it has anything to do with the screen itself. But the digitizer and the multiple layers on top of the screen that the digitizer is composed of.
Newton's rings isn't it?

Yes that is exactly it - the diffraction of light between 2 surfaces, is it normal; however?
Thanks!

Nooo, then maybe what I'm talking about is different. I'm talking crazy screen, weird 'rippling' going on, screen slowly turns more and more white. I know what newtons rings are.. It's sorta visible in sunlight.
So perhaps I'm describing a different issue. Mine is definitely something with the phone, not the layers.

[Q] Screen Discoloration..

Hi Ppl,
I noticed a slight discoloration on my sgs recently. Donno what the problem is. I tried to check the brightness levels, did the screen test and everything seems good. My friend recently bought an sgs and I took a look at his screen and it was way too bright and more of white on this screen when compared to mine.
I noticed more of yellow on my screen instead of true white so anything in white doesnt look really white but a mix of yellow and white
Can anyone help me please?

Uneven Pink Hue - help!

So for the first time after getting the phone I turned on adaptive brightness and pulled slider completely left. I was expecting pink hue but then I realized that the top part of my phone was more pink than the bottom half is that normal?
Could you guys please post a pic of your screen with a white background and adapative brightness on and lowest brightness? I know its too much to ask but it would really be helpful.
Anyone?
I have a similar issue. My bottom half is more pink. It seems like most people have it to some degree.
How did you come to that conclusion?
It does go pink but I've never seen it as you describe.
Please don't bump threads within 24 hours of your last post. Its against the rules.
Sorry about that!
If you turn down your brightness all the way in a dark room with adaptive off and look at a white background - is your screen uniformly pink?

The pink is a bi-product of adaptive. It shouldn't happen when adaptive is off.
My original post says that with adaptive brightness turned off and at the lowest brightness, I can see that the top part of my screen has more pink tint to it than the bottom of the screen. Not the overall hue.

It turns pink below 10% when the adaptive brightness is on but it never happens as you've described Do one thing, turn on the brightness at max and put a full white wallpaper and see if there is any screen burn-in present or not?
No screen burn in. The way to test my issue would be
1. Turn on adaptive brightness.
2. Set brightness to lowest level.
3. Look at a white image full screen.
4. In a dark room, I notice that the top part of the screen has some minor banding which makes the top half of the screen seem a little more pink than the bottom half.

No not answered.
My top half of the screen is more pink than the bottom half at lowest brightness.
The pink is not the problem. The unevenness is.
I think I have the same issue

screen contrast in sunlight

In outdoors under direct sunlight my display contrast looks likes its been reduced ... and the colours seems washed away.. but in indoors with full brightness i got no issue with the display.. anyone facing the same problem ??... can anyone help me to correct this?
This is how intended to work by default. To increase readability of the screen. No way to change that as of now.

Screen brightness
Bought this phone for the good camera quality but nobody told me the camera was only for inside pictures. Once you get in the sun your screen goes all black. Not very handy.

Tint in k20 pro display

Hey guys, hope you are doing great.
I have noticed one peculiar thing, when i sit in pitch dark places with brightness at the end, i face this white issue over my display screen shot attached, it's Google chrome app which showing me these results,(there are many more also)for this to be noticed you must sit in a dark room.
I know it's typical led panel issue and i would like to know if i am the only one?
Do you seriously think we are able to see your display in a screenshot?

If you are in a pitch dark room and see no anamoly then your's display is good. If not you will see a whitish tint over the top area
And btw you can check on your device itself, by just opening chrome(if it's black) and in dark room with brightness as low as possible.

Enable feature in display settings under anti flicker mode to on. and check again your screen in low light conditions.
Yup, that worked, it increase overall contrast for low brightness, is this condition(tint) is normal for amoled panel, or i am just unlucky.
