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.

Amoled problem?

Hello everyone,
I just bought my oneplus 3 but when I am scrolling with blacks in the screen I see something like blurring or blending the black color with the next one for a second.. I didn't have amoled screen again so I don't know of this is normal.
http://imgur.com/xTfrRrh
Here when I am scrolling with low brightness (5%-10%) especially in the last colors the blur is too strong.
Sooo... Is it defective? Should I return it?
Thank you in advance
Edit: https://youtu.be/8KVOvsE_l2Y

I believe that's normal I've noticed it on my screen too but because this is my first time with an amoled screen I thought it's probably normal... I wouldn't worry about it.

Return it. Not normal IMO as I don't have it.

Don't worry, its normal. I had this on my Note 3, S5, S6 Edge and my OnePlus 3, all with AMOLEDs. Its normal

Even with very low brightness the blur is not present?

Even with low. Just tried multiple combinations of screen and ambient brightness and I cannot replicate that glow/blur.
I guess it's not present on all AMOLED panels, similar to backlight bleed on LCDs.

Turn off any third party screen filter or auto brightness apps like Lux if you have any enabled. I experienced the issue you described when I was using lux app

So it's something like 50-50.. Either you are lucky and you don't have it either you are unlucky..

No this is 100% normal and EVERY AMOLED screen has this. For the people saying they can't see it, they are blind. Sorry for being so blunt but it's something that all AMOLED have as the slight purple blur is the turning on of the pixels when they are displaying black. My S3 (had 3 of them), S4, S5, S6, OP3 and any other AMOLED screen had this. My friends OPX Had this, my friends Note 5 had this. Don't worry your phone is fine

I see it as well.

me too ..
and i think its normal

My first OP3 has burn in problems and it also had this common amoled issue, my second OP3 has this "issue", It's normal, I had the same issue on my S4 mini.

THIS IS NOT AN ISSUE, it's perfectly normal all AMOLED have it. Please close this thread as it's useless

I've used various display technologies, all have pros and cons. I suspect that to display something very dark the pixel only lights up briefly. Since it's not much energy used, the various parts of the pixel (RGB subpixels using a certain matrix) light up - but not with the same speed. I'd even more suspect that it's the same with light pixels, but far less noticeable with the human eye.
I would not bother....

jelly scroll on s9??

Hey guys,
I noticed in a few occasions this issue. Specially in low light. Can anyone try to download this picture, zoom in and scroll and report their experience ? I don't it's just my unit... Thank you

I get this as well, but only in very low brightness. I think it is just the amoled screen ghosting which is common with pure blacks

Yeah it's normal with AMOLED in low light with low brightness. Black smear. It's been happening since at least the Galaxy s7

Thanks I was just trying to figure out if my unit was faulty and needed to be sent back for repair or if it's the nature of this screen. Out of curiosity I wonder if iPhone x display suffers from this as well. Also I heard Samsung galaxy s8 did not have this issue??

S20( /+/Ultra) OLED - bad uniformity, too bright dark grays, green tint

Hi,
over in the ultra section, there is a thread about bad OLED uniformity and a green tint, which is really badly visible in dark environments e.g. in the dark grays used in many applications:
https://forum.xda-developers.com/galaxy-s20-ultra/help/green-tint-dark-background-low-t4065621
The attached picture of my display was made by zooming into the (uniform) 5% gray picture in a dark room with 25% brightness using an S10+. It is rather horrible and badly visible in normal usage.
Is anybody here expierencing the same issue? Please feel free to head over there, also, if it is not an Ultra.
Thanks and best regards,
Corwin

I have this problem too. I'm on my second S20+ now and it has problems too. I'll return both. It sucks.

That is really unfortunate. Thinking about trying another S20+ - but I think we should probably wait for later batches. I am also hoping for software optimizations, as it is better at 60Hz - but usually, nothing can be done about it.

How do you test for this ?
Sent from my SM-G986U using Tapatalk

For me, I did not need to test for it, as I noticed it right away the first time using it in a dark environment.
In this post is a 5% gray picture which can be used and instructions: https://forum.xda-developers.com/showpost.php?p=82017239&postcount=17

I also had a bad uneven grey on my 512GB Ultra. Swapped for the S20+ and it's basically perfect. Good luck on the OLED lottery.

Mine does not have this problem. Is related to where the phone is marked for distribution? I'm on a US/Verizon handset.

Mine is also a US version. On ATT. Its just an OLED panel thing. Samsung used to have this issue a lot back in the S6 through S8. From S9 and Note 7 and on screens were great. I think with the new 120HZ screens the uniformity issues came back.

I think so too. S8 was really bad. S9 and S10 were great. S20 is bad again.

Exactly. Gotta be the 120hz thing.
If anyone has a really bad grey screenor not uniform. Return and reorder. Samsung customer care won't understand the issue so might as well just order a new one and hope you get a better one like I did.

Too bad my second one is still bad. Now I return both and order a Snapdragon model.

Oof. Good luck. Mines Snapdragon. Oh and Snapdragon is the better variant now anyway.

should I be worried if my whole screen is green when showing this 5% picture in dark room? upper part of the screen seems to be slightly brighter green - it is my first samsung and I cannot find anywhere how ''good'' oled 5% should look like...

My opinion: Of you need the picture to see it and do not notice it or if it does not bug you, you are fine. If the display is uniform, whatever it is like, I think it is ok.

Absolutely!

I have the same issue, S20+ 5G Exynos

So how do you test this again? Using a dark grey picture with the brightness set to 5%?
ETA: NM, I read that wrong. I downloaded the image and tried it at 25% brightness. I'm not seeing the same thing? Is it meant to be dramatic to be able to notice if it's a bad panel? I'm seeing a normal display?

On number 5 I can say that it is finally bearable. It was manufactured on the second of march. I did not check with the rest. I only opened them, handled them delicately and checked them. All were terrible.

screen yellow tint on left side and blue shadow following scroll

At low brightness states between 5% and 15% , I notice
a yellow tint on the lift side of the phone, especially on grey background, but It's better seen in a dark room, like when I'm scrolling at night.
can you guys tell if it's a software or hardware problem.
I can't ignore that odd uniformity in colours.
There is also a blue shadow following my scroll down in the same conditions of lightinig and brightness.
Here's a link showing the problem

Here are some pics, I wish they are clear enough

that's called smear. it happens on all good amoled screen. it's even exist on 90Hz display ex: op7t. but it hard to notice it because of 90Hz refresh rate.

It doesn't sound comforting when you say "good amoled screen" It means the technology is basically crap
Does it exist on Galaxy S20?

i have j7 pro, a71 and op7t.
j7 pro has less contrast than a71 and op7t. and j7 pro doesn't have noticeable smear as a71 and op7t does.
this is a refference where i get those information https://amp.reddit.com/r/GalaxyS9/comments/9brauw/black_smear_test/
as stated in link above, every pixel in amoled is on and off. when you're using black theme and low brightness and trying to scroll.as fast as possible. the led at certain location need to be turn and off as soon as possible. it makes smear noticable.
