Reddish brown tint when the screen dims - Samsung Epic 4G Touch

Anyone else notice this when the screen dims or you lower the brightness pretty low? It looks fine at full brightness.
I'm on my 2nd phone, swapped my last one due to a camera issue. My first phone didn't have this tint

I've heard OLED-based displays have inconsistent while balance, especially at varying brightnesses. I use Chainfire3D's nightmode to set a custom color. Totally worth it.

Does this have the pink issue?

Hello All
Just came across this forum and a thread on the pink screen issue.
Do you reckon this one has the same issue?
All of the phones are the exact same and have the exact same "issue". I use my phone on maximum brightness all the time so I never notice it. It's only noticeable if you use the phone on the lowest brightness setting (Why anyone would buy an AMOLED phone just to use it on the lowest brightness is beyond me)

Yes i'm fairly sure they do. But at anything over the lowest brightness it doesn't occur. Again, why you would buy an AMOLED to use it on lowest brightness is beyond me

Check the appropriate thread: there is a huge difference between handsets. Most are like this, some are totally unaffected and some are basically defective.
Yes poor answers, I do not have any pink even on the lowest brightness settings. This means your device is defective and you should get it replaced as many others have done. And yes there is a thread dedicated to this issues:

Im a total OCD for these kind of things. pink issue, dust under screen, dead pixels etc... I don't have the pink issue. It was one of the biggest concerns for me when I ordered the phone. I had seen sample photos from the nexus one that had pink etc. I think there are two issues. A screen issue, and a camera issue? anyway, I don't have pink in my screen at low setting (which I use ALL the time indoors to consevre battery) or any other setting. I also don't have pink in any pictures or videos I made with the phone.

What do you think of the examples i posted?
I only notice the off-pink tint in GMail. Nothing major tbh.
I cannot see any pink on your photos at all, but I went to my brightness settings and copied what you did in the screen shots and YES my gray looks like it has a red/pink/rose tint at the VERY lowest setting. At 5% brightness it's fine, gray. at 0% setting it has the rose tint. This is NORMAL and a limitation of the display technology (pentile matrix). If this is what you mean, your screen is normal. It's only certain shades of gray that will be affected by this and normally only at minimal brightness settings. I thought you meant you had a pink blob on the screen centre etc? If you just mean the gray menu and ntificaiton bar etc appearing slightly rose coloured at lowest setting, this is normal. I presume the grays are fine when the you move the brightness bar up from 0% to 5% or 10% setting?

Thanks for taking the time to reply

Green tint?

Just got my VZW galaxy nexus, and im loving it so far, but have noticed something odd: toward the top of the screen (about 1/4 of the way down from the top) there seems to be a very slight green tint, noticeable only when looking at a dark background (like the settings menu).
It's kind of hard to explain, does anyone else have something similar on their phones? Is this normal for amoled screens or should I ask for a replacement phone?
i believe it has to do with it being a pentile screen... well, 'HD' pentile, but still..
i'd say if you try an exchange, make sure you the test the other in store first.
can anyone with a galaxy nexus please post a photo of their phone on the settings menu? (scroll all the way down)

Pretty sure the setting menu is a background gradient with an intended color shift.
But yeah, mine has a blueish/greenish hue if I tilt the phone away or towards me in portrait mode. Straight-on, I don't notice anything.
yeah i am talking about viewing straight on
mine has this greenish tint slightly at the top right screen...
that settings menu then scroll all the way down is normal.. the color is not as dark as the top. I'm seeing greenish tint when on white background
I have a very light greenish tint on the right side of the phone on white backgrounds with text when at low/automatic brightness. The green goes away when I bump brightness to 40%+.
Did you try that?
Oddly, when I ran pixel checker, the pure white background has no green tint to it at all.
Yeah, at low brightness I see a tint/haze but at full brightness, everything looks beautiful.
Welcome to the world of pentile.
I see the same green tint on my screen. I thought it was normal, but I compared it to another unit today and saw that my display was both dimmer at the same brightness level and had a greenish cast and different color temperature than the unit I was comparing it to. I'm not sure if this is within the normal variance for these displays, but my phone certainly looks worse to me than the one I compared it to.
Both units also showed a green/blue tint when viewed off axis but with greater discoloration on mine. The second unit showed almost no discernible tint when viewing a white screen straight on unlike mine.

i have the same problem. Sometimes (usually after a power down and restart) my entire screen is very dark and has a, very obvious, green tint to it. I compared my phone to my girlfriends at the same display setting and the tint is very obvious (especially when i'm viewing menu, text messages, browser). When i adjust the brightness it seems to make it less obvious, but still there. However after certain power down and restart this "green tint" seems to 'go away' only to either gradually re-appear or just happen when my phone self adjusts to "automatic brightness" setting.
p.s. my phone also, had another minor issue of random re-start when listening to music (via google music) and adjusting the sound effects option. After that restart my phones display was significantly tinted and dark. Weird, Either way getting a replacement unit tomorrow.
Mine has a very slight green tint on the left hand side of the screen when at the lowest brightness and viewing a white background.
I normally have the brightness bumped up a bit, but it still bugs me when I have it low
EDIT: Checked pixel checker, has the green tint. I can definitely see it on the keyboard as I'm typing this though
I took my unit in to Verizon today for an exchange. New one doesn't have as significant of color shifting or banding issues.

yeah i got mine replaced the next day, all good now. No green tint, reduced banding, and much better viewing angles (the first one heavily tinted green or pink colors when viewing it from the right or left side, respectively)
Alright, got a replacement today.
No green tint that I can see, almost no banding and the colors don't change like, at all when I tilt the phone.
Now my nexus truly is perfect

Sorry, I find this very hard to believe. *ALL* pentile AMOLEDs change colours like crazy when you look at them at a sharp angle. It's a characteristic trait of this kind of display.
Pics from various angles or it didn't happen. ;-)

Yeah, I was exaggerating, but compared to how bad it was with the other one its crazy. Very less noticeable than my first one

How's everyones screen color/brightness uniformity ?

I had ordered OP3 on the day of launch and got it the next day. After using the phone for about 5 days, I noticed that the top part of the phone had a bad pink tint which was clearly noticeable on White and Grey backgrounds at any brightness. I sent the phone back for replacement and got a new one few days back. The phone looked almost perfect and have been using it for around a week now. Yesterday I bumped on another thread in a forum when I saw a peculiar screen uniformity issue in only one particular shade of Grey.
Steps to reproduce the issue
1) Open the below link in Chrome in a dark room.
http://www.nullabletype.co.uk/static/styles/blah2.html
2) Reduce the brightness to just above the minimum brightness (5-10%) with adaptive brightness turned off.
3) Go to Display settings --- Turn on Night mode --- Increase the slider below to the maximum.
4) Scroll to the 3rd image (the one after Black)
5) Mine has uneven brightness. Some part of the screen is darker than others.
6) Increase the brightness to say 25-30%. Everything looks uniform.
7) Scroll to other images (other shades of grey) and no screen uniformity issues at any brightness.
Now, I am not sure if I should send this back again. I don't use such brightness levels even in night and I don't see any screen uniformity issues in any other brightness levels or shades. I also searched in internet and found similar issues being reported in Nexus 6P, S6, S7, etc in Reddit, xda, etc. There are people who have RMA'd their devices 5-6 times without much luck. From what I have understood till now, AMOLED's are not really perfect in displaying Grey at extremely low brightness. Or may be, its due to the current software targeting the NTSC Gamut ? Anandtech recently said that sRGB update (coming in 3.1.4) has made considerable improvements in Greyscale accuracy.
Before I even think of sending the phone for 2nd replacement, I would like to know how's the screen uniformity with others here.
I did the screen test the moment I got the phone everything turned out good, I was really worried after reading the reviews on the net about the screen. But it seems like only handful of people are facing the problem.
Can you please let me know how you tested it ? I too had tested it on Day-1 since this is the second OP3, using "Screen Test" app and everything looked good. Only one particular shade of gray at low brightness creates this problem.
Not exactly 'real life' usage?? Haha
Looks fine on mine. Uniform grey across the whole screen.
Yeah I definitely have the same uneven brightness on the dark grey on the right side, it's even visible on the notification drop down. Like you, I'm wondering if it's something that can be fixed, or something I should bother RMAing, am I just gonna have the same thing again? It's strange, it looks like uneven backlight but there is no backlight.

Black Bleeding on Screen

So my screen is having issues when I scroll and I know this happens on this device. The question is do all the devices do this or is this just an issue with certain ones. Is my phone broke or will it be fixed with an update. The smearing is pretty bad and I notice it even with the brightness turned up.
Every OLED device I have has done it, but I haven't had an LCD device for a while. So I don't know if it's a characteristic of OLED screens or all screens. My last device was Samsung and had it pretty bad.
I'm having the same issue,
It bleeds/smears with dark/black color when used in dark i.e no light in the room.
I think it happens all the time, just that its visible and annoying when we use it in dark.
What did you do? Did you get it replaced?
Hi!
Same here... It seems normal, anyway with two years warranty if something is wrong with screen (black bleeding, burn in, ...) Google have to repair it or change the smartphone.
Regards!
It should only be visible in low brightness. It's normal for oled but the pixel 2 XL is a bit noticeable because Google set the gamma to high. So it can actually be improved through software.
If you see black smear etc during the day and any other time than maybe at night when the screen is at low brightness I would rma it
Seems like sensors are causing problem if move phone around in dark it will go away I have a case and tempered glass on phone

Screen quality and uniformity

Hello,
Are you satisfied with the screen quality? Mine has a yellowish tint at the bottom.
I don't see a yellow tint
You mean like this?
https://www.reddit.com/r/Huawei/comments/9wqfrw/help_has_anyone_experienced_this_lcd_backlight/
If yes, then yeah I have that too :/
Not too thrilled about that
I have something similar bleed, but it's only visible a very low brightness, like very near to 1%, I'm using display tester app to see it, with auto brightness in dark room isn't obvious.
Regarding a yellow tint, I think that my bottom half display as a slight warm white, it depends of brightness and the room light, angle that I watch the screen.
