Green tint on greys

Is this normal? Greys have a green tint which is really noticeable on low brightness. Is this a limitation of AMOLED? But I don't recall this issue on my 6P or Note 4.

Hmm. Not having this issue...

Greys are really greenish. Though it happens only at some certain brightness level (a little more than the lowest).

The panel apparently is of low quality and has issues with greys. It's detailed in the anandtech.com review

Not noticing this on mine either.

I may have a slight tint on mine on greys, only on one half of the screen though. I'm colourblind so it could be green. I'm thinking it's more purple-ish though...

Yes what I had experienced from my last 3 phones I.e galaxy s2,s3,s4,s4 mini,s5 all of em which had amoled screen all have this thing. Its like if u seen u can't able to unseen. But its hard to notice. I think these displays are rather builded like this to work. Even my brother's new s7 has this thing.

On only part of the screen though? I know when tilting AMOLED displays that can happen but head on I don't know. (I've avoided AMOLED up until now because my last couple experiences with older ones was not so nice)

Guess that answers that, cheers!. (although mine might be right side of the screen, not bottom)

On my phone, the bottom part is also "greener" than the upper part. This is especially visible when brightness is set low (which I do when not outside, because it totally suffices).
Do more people have this problem?
Would returning the unit and getting a new OP3 make sense, or are these unevennesses typical??

I'm wondering if it's just an AMOLED thing... If it's really really bad then you may be better off RMA-ing it of course.

The findings on Anandtech have nothing to do with the quality and everything to do with the calibration, which is just software.

Hi, is it darker like the pics from my thread? I think I have the same issue on my display, just at the middle of the screen.
http://forum.xda-developers.com/oneplus-3/help/dark-line-oled-screen-t3402293

One thought came to me: In the upper half of the OP3 are the parts which get warm when the phone "works". Perhaps the part of the screen which is warmed up regularly loses a bit of green tint, while the lower, colder part remains as it is??? Just a thought...

I get a weird purpley/dark colour on greys and when scrolling white font on black background, but only on minimum brightness.
After reducing brightness below a threshold (just above the minimum) the colours across the display seem to shift

I got my replacement phone today. And. The display is even more worse. The colors are uneven, like some of them have here. The bottom is greener and the top slighlty pinkier/the correct color.

Argh. That's what I'm afraid of (sent my device in for replacement on Saturday):
That, as a replacement, simply someone grabs a box with a new device and sends it to me, without testing.
Edios, what did you write in the service request as your reason why you want a replacement? Did you write about the display problems?
Welcome to the lottery...
Does anyone know: If the 2nd device also has a defect, and the 14 day return time since I got the 1st device is already over, can I demand from Oneplus that they take back the 2nd device and that I get my money back??

I didn't even mention the issues, Amazon immediately gave me a replacement.
The problem is, they provide only a single replacement and now insisting to give a refund. But I want this device cos there's no other device that I'm interested in. And it's out of stock also.

For what it's worth, these sound like typical AMOLED issues. There are long threads in the Galaxy S6, S7, etc. forums with people experiencing the exact same thing. AMOLEDs just seem to not be as consistent as LCDs in the quality control department and it's always just the luck of the draw whether you get one with green or pink tints or not.

How prevalent is black crush?

This is one issue that actually affects my user experience. I'm trying to decide between an RMA and switching to a Pixel 2. If black crush is a universal problem, I'll go with the latter but if it only affects a few devices I'd rather RMA and stick with the P2XL. Chime in, black crush/screen bleed - do you have it?

I have it. Very noticeable. Curious if it is widespread or not, as well.

When is it noticeable??

FYI - the Pixel 2 has it as well.

I seem to be finding mixed messages on this. Some report this is not an issue on the Pixel 2 and only the XL. I only have an n of 1 for each device - my P2XL has it, my wife's P2 does not. Ultimately, this is what I am trying to figure out - how widespread is the issue, do I play the lottery or exchange for something new or just keep my original XL, though I'd certainly miss the camera and active edge.

Low brightness, dark videos and images, basically any near black colors get "crushed" to black. I was watching The Croods on a flight the other day and there is a dark scene near the end of the movie where I couldn't make out what was going on because it was so bad. Any dark area of the screen went completely black and/or black and very pixelated. There are a few test images in a thread on Reddit to see if you have it, I'll see if I can link it.

Ok I do have it. See if on low brightness. Pretty annoying. I noticed it's slot worse with night mode on

I found blacks at low brightness to be quite extreme as well, I'm fairly certain this is something that could be recalibrated in software but I doubt that Google will do anything about it

See I don't think it is necessarily the screen as the display has a really high range of greys, so I think it could be fixed to some extent. The bigger problem I have is the ridiculous amount of black smear at low brightness. I never had anything like that on my Nexus 6P, it is dreadful.

Yeah same. I've got a decent unit at normal day usage. Once it gets to lower brightness and night mode is not very nice. The black crush is slot worse with night mode
.but black smear is there with or without.
Wish Google just went with a Samsung panel

Yeah, this is kind of a weird one as it seems to affect both P2s and P2XLs, but not all. Maybe its mostly a software issue but is most pronounced on certain screens for some reason? Idk.

It is difficult. Also do you trade in for another one? But run the risk of getting worse blue tint or grain or uneven whites... I'm going to give it a week, see if I find it a big deal or not. 90 percent of the time I don't notice because the brightness is higher during the day

Recommended settings or tops on how to use it? Any reference images or videos to use?

Wow, so I've got a pretty bad unit...
Black Smear: Even on full brightness and slow scrolling. So bad, it even covers Text to the unreadable (It's complete gone and "hidden" under the Black-layer).
Black Crush: Until 40% noticable on Photos. Mostly in Shadows which are normally grey. They turn to a complete Black which looks awful.
Blue tilt: Starting at a very small angle. Pretty extreme and bad, but the other two are more of a dealbreaker for me.
Currently requesting an RMA after resetting my Device. And be sure to be nice to the Support. They did not manufacturer this Device wahtsoever.

Here the original thread about black crush https://www.reddit.com/r/GooglePixe...ck_crush_on_pixel_2_xl_and_possible_solution/
Play with the settings to ur liking.

I don't see anything wrong with blacks or greys during videos or on pictures whether night mode is on or off or brightness is high or low. Can someone post a screenshot or two? I'm curious.

Screen Problem

Hello, I've noticed that when I use my phone in night mode I can see green areas on the screen. Are there other people in my case?

No on mine so far. Black is black no greenish.

is see this too sometimes esp at night when its dark in the room with no other lights - in the day when its brighter is not visible
it does seem to be an issue with some backgrounds as i noticed in apps where the background is black (not dark grey or greysh) this isnt visible
so not sure whats going on - but i didnt had this issue with the s10 .....

Yes, I have the same problem, it comes from the screen according to what I read on some forums. Some OLED screen have problems. I think I'm going to get it exchanged.

no issues so far with mine s20+ (exynos variant), however if i were you i would seek to get replacement

Screen sorry ^^

ok but how do you explain that its only visible sometimes and then sometimes is not?
and is only showing on grey backgrounds etc
like now i have the phone in my hand and is looking ok
the best place to test is in the samsung daily or SMS app - the top part of the app thats meant to be black was sometimes showing more like greyish - now is proper black again?
like i said it seems to be dependent on the ambient light - i wouldnt want to replace the phone if its not an actual issue esp since it took me a whole day to get my stuff transferred and setup

Oled is known for reduced quality the lower brightness you go.
But all units will have varied levels of tints etc

In my case..

Unfortunately, yes. Also, it is more noticeable at 120Hz.
There is a thread about that in the Ultra section:
https://forum.xda-developers.com/galaxy-s20-ultra/help/green-tint-dark-background-low-t4065621
I also tried to get people with that problem in the S20+ section:
https://forum.xda-developers.com/galaxy-s20-plus/help/s20-ultra-oled-bad-uniformity-bright-t4067051
It is rather horrible and i noticed it right away the first time I used it in the dark. I think it can not really be fixed in Software, but it can be probably made less noticeable, as 120Hz is making it worse.
I wrote an 'email to the CEO' about that here:
https://www.samsung.com/uk/info/cont...email-the-ceo/ (example: UK)

If its same as below thread...Welcome to OLED!
Colour blending (blacks) problem
https://forum.xda-developers.com/galaxy-s9-plus/help/colour-blending-blacks-problem-t3765385
Had this on my S9+ and S10. Nothing can be done about it.

Using OLED since 2010. Starting with Symbian Nokias, Windows Phone Nokias and switching over with the S8+ - OLED only.
I suppose - never had a display that bad in this regard. At least never noticed it that bad right away. The upper right corner is almost always showing a green tint.
But I am glad, if it is not too widespread - then the S20+ I ordered will probably be fine.

in your case what?

Pardon me?

Hi,
Just attached a picture of my screen with adaptive brightness with low light with screen at 120Hz.
At 60Hz the screen is even, at least almost even.
What is your opinion?
Thank you in advance.

Report it to Samsung, probably get it exchanged, if possible and it really bugs you.
I gave back the ultra because it was too much green tint. The plus has it as well, not as bad as the ultra.

Question Low brightness (not dimming) on F3 ?

Hi to all.
I've received my F3 today. I'm so happy.
The only flaw I've seen on it is about its brightness : it seems to be a bit low and we must push it quite almost 100 % to have decent brightness. To those who have received the phone : did you notice that ? I'm not talking about dimming but regular brightness for regular use (not heavy use)
Thanks for your answers

I'm yet to able to order mine .
However, listening to reviewers the brightness curve apparently wasn't very even. Might be able to be fixed in a custom ROM

Yeah maybe.

I can not confirm. In very bright surroundings, like outside when the sun is shining, it gets very bright. I have nothing to complain about.

I don't have any complaints either, the maximum brightness is excellent. Compared it to my brother's OnePlus 6T and the F3 is for sure brighter.

Same as OP.
I got my F3 this morning and the brightness is the same as my old MI 9 SE. It should be not
I think it's a software issue.

Paradoxically display seems to be brighter as few hours ago. What are your settings ?

brightness seems fine to me,but unfortunatly it doesnt get as bright as a oneplus 8 indoor on max brighntess, but in the sun(max peak), the display of the poco is a bit brighter, so i am satisfied with the results.

yep my old s8+ has more brightness than this xiaomie noodles phone so sad i am disappoint with my purchase

Seems like a lot of people here like to have their brightness set to retina burn mode.
I haven't used a OLED display phone yet but I'm pretty sure it'll be brighter than an IPS one at 450 nits max, even then I only have the brightness set to about 75%.

No way to measure or really compare it to other recent OLED screens, but it gets bright enough for a sunny day outside here in the Netherlands. More sun to come hopefully... Also it seems to pump up the contrast a bit when in direct sunlight which is helpfull.
So no complaints here for outdoor readability.

Yea it's brightness is less than my oneplus 7t pro but it's Amoled is way better than my old phone when I watch YouTube video.

Hi all,
I have just experienced a brightness problem,
It went very low on its own while not being in auto mode,
It even affected the brightness while the phone was off and charging, which scared me a bit lol,
I was about to seriously consider a factory reset and the brightness came back to its original levels,
The "brightness bar" was still at max during the issue,
And i think it is because i've stayed for too long under the hard sun , playing videos for one hour or two and it happened while i was reading an article on Chrome.
Gud day!

Question Red Magic 8 Pro selfie display

I got my Red Magic 8 Pro EU 256gb 12gb today.
While I was testing it I noticed the selfie camera display shows up in alot of situations, like on grey situations the display turns green at low and max brightness.
Anyone with the same problem?

Hi!
you reach out to the manufacturer or retailer to report the issue and see if it can be resolved. If the device is still under warranty, they may be able to repair or replace it for you.

Same issue here, but looks more like a software issue to me.
When you touch the screen, the camera overlaying part flickers and settles after a second to the color it should have. Perhaps they just need to speed up this process.
If on the other hand you mean a permanent mismatch, they just need to recalibrate.
Either way it is fixable by just software.

This is just some examples, that display covering the selfie shows up alot for me.

Okay i see, yours is quite more visible than mine. Mine is only really visible in dark gray background, but does not have this green tone to it.

Mine also has it although it's just visible when the brightness is from 0 to 15, and I think it's perfectly normal.
Green tint is more visible when the display is set to 120hz, and lightens or "flickers" when idle because it switches to 60hz to lessen power consumption.

The grint tint is more visible on higher refresh rate. It "flickers" because once the display is idle, it switches to 60hz to save battery.

I am starting to be glad that I missed the first shipment... as days pass by more and more issues come up with this phone.
First this display issue that the camera is visible and in another thread overheating issue.
Reviewers said that the camera is not visible during normal usage and only in really heavy sunligh from the side and they showed 97% stability in 3DMark.... both have been disproved by users feedback here on XDA.

Perhaps they're using it with high brightness that's why they did not notice it. Well, I'm hoping it's not a factory defect or whatnot. Haha.

My camera is only visible on very low brightness levels, and I also haven't noticed any overheating problem. The only pet peeve I have about it is, that there's no global audio equalizer, only in game space. And that one disables once you put the phone in standby.

That is disappointing, it should not be visible at all, expesially not in low lit enviroment.

Same issues, combined with weird brightness flicker and other software issues... pretty disappointed, hopefully they will be able to fix those issues... coz otherwise phone is pretty good, software is garbage tho
