Screen quality

Anyone else find the screen to be lacking sharpness?
I'm coming from a gs5, and this phone doesn't seem as crisp with text as well as images.
Went to best buy tonight and looked at the 3 they had on display and they all looked the same.
I also think the colors are muted compared to the gs5, but I'm not sure if that is a bad thing or not.

the colors "seem muted" to you coming from a gs5 because the gs5 colors are saturated. the note 4's colors are more closer to the right color spectrum than any amoled display has ever been. the note 4's colors are more natural, more realistic.

Thank you, I do understand that. But it still doesn't explain why the screen seems blurry compared to the gs5.
It's almost as if everything the extra resolution is causing it. If I look at a very high resolution picture, it appear to look fine, but then everything else seems slightly off.

I thought I was the only one. I got my Note 4 yesterday and of course I didn't take my eyes off of it for a good hour or so and I thought it was in my head that my vision was blurry. After reading that the phone may not get root and the display disappointment, I'm strongly considering taking it back and keeping my S5.

If you compared it to a GS5 you wouldn't think the same. GS5 screen is best I've ever used.

Have you tried changing the screen mode options?

Yeah, doesn't do anything except change the colors slightly. The more I'm using the phone the more I get used to it. I really hated the S5, so I'm not going back to it(the bluetooth wouldn't work properly with my car).

My S5 is right next to me displaying the same images and text and I have to disagree with you. Everything is just as sharp or sharper on my Note 4 screen.

This.
At the PPI we're talking about for all three phones (Note 3, SGS5, Note 4) unless you have better than 20/20 vision and/or are holding the device less than 10" away differences in sharpness wouldn't be detectable. Difference in display quality yes. It's about visual acuity which is the lowest common denominator.
As for the Note 4<>Note 3, the display seems "better." What better means to me (which is purely subjective) is it's brighter on the same setting I previously used, it seems crisper, and the colors seem more realistic.

Subjectively, based on your tastes, sure, why not. Objectively, not so much...
Our detailed Lab tests show that there have been significant display performance improvements in the new Note models [4 & Edge] including higher resolution, higher absolute color accuracy with better calibration, higher peak brightness with improved screen visibility and readability in high ambient light, and higher display power efficiency, resulting in a number of new records for Smartphone display performance.
What is particularly significant and impressive is that Samsung has been systematically improving OLED display performance twice a year with each Galaxy generation since 2010. With the Galaxy Note 4 there are many significant improvements over the Galaxy Note 3 that we tested a year ago, but also with the Galaxy S5 that we tested in March, and Galaxy Tab S that we tested in June. The most impressive improvements for the Galaxy Note 4 are in the pixels per inch and resolution, the Absolute Color Accuracy, Peak Brightness and screen viewability in High Ambient Light, and display Power Efficiency, which we discuss in turn below.
http://www.displaymate.com/Galaxy_Note4_ShootOut_1.htm​​

Here is a side by side. Maybe it's just because everything is bigger that it looks slightly blurry to me.
Not sure how good this will look.

The only thing that matters is how you think it looks. Like so many subjective things discussed on XDA (lag, battery life, overheating, build quality, AOSP vs. overlay) if you're looking for consensus it ain't gonna happen.

I was referring to how the picture came out.
Edit, because it was taken with a crappy iPhone 6.

On my screen some apps makes the whole screen color go 10shades higher, if you catch my drift. Is anyone else having that issue?

Screen has a yellowish tint - normal?

Yo guys, just got a G4 today and I'm happy enough with it however coming from my G3, unless my eyes are playing tricks on me, the whites just seem to be a fair bit whiter on the G3 and the G4's display looks a lot warmer. . I'll see if I can capture it on camera, but does anybody else have this issue or could it just be the case that this is how LG intended the pannel to be?
Just to mention that I can't compare it to a display model as the phone isn't stocked in my country.

Ive looked at like 5 G4 displays and none of them are the same

Dang, so it's essentially the luck of the draw if you get a good pannel? :/

Mine looks great, no tint color at all.
I'll check my friend's later if there's inconsistency or not.

I have 2 G4's, which I have already replaced one of the 2 I have. None of the three screens are the same. Also brightness differs quite a bit between the two I currently have. lastly, one is more yellow while the other is more blue.
Its a pretty large discrepancy between them

Hmm... I've no idea if I should send it back and get a replacement or just simply get a S6. I really do like the phone apart from the issue.

IMO ? Getting a S6 in replace of a G4, it's a rollback.

I'm noticing that on mine too. I currently have two G4s because I still have to ship one back, but the one I'm returning has clearer and crisper whites than the one that was sent to replace my old one. But the new one I got has so far had much better battery life so I think I can deal with having the screen be slightly worse if it means the battery lasts longer.

Get it replaced the G4 screen is actually a colder than normal looking screen.
personally i prefer warm colours as its easier on the eye but if you're into your whites then they should be colder. The tint wont go away. I rcall people with one plus complaining about it. However it was a bit more blatant as in one part of the screen would have it rather than the whole one.
There is variation between screens, the brightness has been mentioned by reviewers. I think its the usual kinks from early runs of the factory cycle. people buying later will have less issues.

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.

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.

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.

Terrible screen tint/uniformity

Hi guys, looks like OnePlus have got some quality control issues. My unit has terrible colour issues with the display. It's very noticeable at low brightness levels and still apparent around the 50% mark. I've reached out to OnePlus about sorting out a replacement unit. Since they don't offer advanced RMA I don't hold out much hope for a quick solution!

You have to go for RMA

this is why I switched my order to Amazon.
should be much simpler then dealing with OP.
hope you get a better unit and this is not wide.
so far other people with pop up orders not had this issue so maybe its not wide issue

Sorry to hear this. Just tested my UK one and no such issues.
Reminds me of the mate 20 pro

A few other people on the Telegram OP8 group have this. Wonder how many are affected?

Can happen with any phone with oleds. Get it replaced

Seems this is similar issue as with s20 ultra panels. They also have quite a few green screens at low backlight. Mine seems more or less uniform but still has strange tint on low brightness. Someone mentioned to try to turn DC dimming in experimental settings to lower the impact of low brightness, but I havent tested that.

I have a similar problem with mine. It looks like clouding with a dark grey background at low brightness. I have also figured that it's far worse with 120 hz vs 60 hz.

I am located in Germany and we can return the whole thing within 2 weeks, no questions asked. I am not dealing with them to inspect the phone etc. I will just send it back. Too bad, as I ordered a blind box in a special promo action and got a lot of accessories in the box. But still not worth it.
Interestingly the "burn ins" or what ever it is look very similar. It's the worst on the buttom/side of the phone and around thr front camera, in all the pictures I have seen. Also it's worse at 120 hz compared to 60 hz for me. Why are those problems at similar spots though? ?

This isn't good. Wonder if the 1300nits/high refresh rate is damaging screens.

Has anyone got their device and using it at 120hz fairly bright with no issues. I was tempted to order one tomorrow but this is putting me off a little.
