[Q] Ugly smudges on screen. Warranty return?

Hi everybody.
I bought my Nexus in December, and some time ago I noticed that screen looks ugly on certain backgrounds, mainly gray ones. So I did a little investigation and it turned out that I was right: picture looks mostly okay on primary colors, but grays shows terrible smudging. I took a photo of it. Do you think it qualifies for a warranty repair? Any of you noticed something like that?
I attach a photo, it's out of focus on purpose, because otherwise there would be a rainbow goo on screen.

The screen doesn't look good at lower light with certain colors that's just how it is..
The smudges look like someone wiped the screen with their thumb.

Screen was cleaned before taking photo. This rainbow effect is more or less visible on any background, but gray is especially bad. Even scrolling webpages is a bit annoying, because starting from top there is a pinkish stripe, then normal, then pinkish again... Yuck.

i have the exact same problem! Gray and white is the worst, and lower backlight is worse. But I realized this is mainly the glass top's fault, while i scroll a page, i can see those sumdges staying in the same spot!, don't know whether a protecting film will help or not.

joshdu1125 so I'm not alone then. I had a protective film on screen until yesterday and removed it because I hoped it was it's fault. Turned out it's not. Contacted Samsung via email, wonder what they will say.

Handtec said that some of the first phones (first batches) have worse displays than newer batches. I already sent my phone to them to be replaced.

screen issue
looks like its more or less same problem experienced by G.Note user, like myself..
G.Note Screen Problem Thread
try get "screen filter" from market and lower the intensity of color to let says 30%, check that same grey image, how does it look?..
My screen is much worse than urs if u wanna see... =.="
I am starting to think this problem is universal to all Samsung devices.. Zzzz

unfortunatey this is a problem with all samsung devices i suggest getting a kernel with color control such as francos or glados. its a lot better then the color control filter app and runs super smooth , francos kernel also pretty much doubled my battery life.

rey5757 you are right, less brightness = problem more exacerbated. I you have a photo of your screen, let us see it.
amcmearty I'm using Franco's kernel right now, but tried others too, to no avail.

just go to G.Note thread in my last post, at page 65. I don even have to take "out of focus" photo to see it.

This is a problem with the screen at lower brightness levels.. it happens to just about everyone that greys and whites look bad.

My phone also has the red stripe, and white is not uniform.

The problem with this shadow thingy is that is varies greatly on difference screen.
The "Size", "Darkness", "Area" of shadow are INconsistent. Some screen have shadow on top area of screen, some have it at corners, some have it at lower bottom, some have it all over half or screen. Then some have it but barely visible(maybe this fall in perfect screen category), some have it but extremely obvious..
How is all these random quality screen fly out of Samsung?..

¿Samsung? No thanks: P

vertical lines. blobs..etc

am i the only one that is noticing this? while its not as apparent as it was on t989, this phone seems to have blobs, vertical lines and other screen defects
link to the issue thread for t989
http://forum.xda-developers.com/showthread.php?t=1300133
ive went through 2 phones(one had physical defect) and both had this issue, so im going to guess its probably pretty widespread.
anyone wanna check their phones for these as well?
since blobs, lines are not acceptable on a 600dollar phone like this
To find the blobs/lines, look at grey background at night with no other lightsource than the phone itself.

Mine has a small line but it's like dead in the middle of the screen.

mine too, only 3 small blobs, and a line
the thing with these screens is that the oleds are controlled by a voltage regulator, and when you turn the brightness down the voltage regulator can't neccearily provide enough voltage to the screen, which causes the issue we have
i was hoping samsung would have fixed this issue by now..its a surprise that they havnt

just to add
this is the kind of technology samsung needs;

No, this is not black crush, the blobs and vertical lines are something else.
blackcrush does exist for these phones, but mura and vertical lines exists as well.

i wish i could
having had an T989(tmo gs2)
initially the screen looks like what we have now
just look again in a year, the lines will become so apparent that youd want to smash your phone
in either case, it would bother a lot of people when they us their phone at night.
not to mention that this is a 600dollar device, it needs to be flawless!

nothing does indeed, which is why im glad my credit card gave me a 2 year warranty on this phone
in either case, ive posted this so people are aware that this issue exists, should they take action against samsung

The 1st unit I had were free of dark lines; but I am confident that it had the mura effect as well but was much harder to find since the dots were concentrated on the edges (near the bezel) of the display; if you look carefully at all the T-Mobile note 2's, they all have the AMOLED issue. I did notice on my first unit extremely faint stains throughout the display just like in the demo unit (in black background), but the lines were not there and hardly any dots. However, the whites on my 1st unit were somewhat dull, not as bright as the demo unit at the store, and had a yellow tint on the 2nd half of the display, and a light pinkish hue to some extent at the center of the display in a full white background, and also had faint horizontal lines (only when looked carefully) at lowest brightness in a white background (which became worse and more prominent over time).
My 2nd unit, though it does have a 1cm black line in the middle of the display, with 3 or 4 dots on the top and bottom left of the display, the whites are true whites, and the display is much brighter than the 1st unit I had. No yellow tint to be found, no pinkish hue, and no faint horizontal lines at low brightness and white background! Surprisingly, the color and brightness uniformity are flawless on my 2nd Note 2 (throughout the display, white is white, even brightness) , compared to the '3' Galaxy S2's, '1' Note 1, and 1st Note 2 I owned in the past. Best of all, the build quality on my 2nd unit is also better, no squeaking bezel or back cover, and hardly any blemishes on the bezel. The light which was leaking through the home button is almost gone after a couple of weeks of use.
So far, it seems like my 2nd Note 2 is a safe and clear winner; really hard to find a unitform AMOLED display these days and my 2nd Note 2 just so has one.
Why send something back as a result of finding the slightest chance of a mura effect when you might get something worse in return.
Like many say on the forum, "I guess you can't get it all."

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 issues

I've had 2 Oneplus 3's now, and am now in the process of sending the second unit back for a replacement.
This because the screen wasn't functioning properly, there was lightbleed on both and the screen had a green tint on one side and a red tint on the other side.
Has anyone else experienced issues like this? Is it a known problem, big or small? Or am I just in really bad luck by recieving a bad screen 2 times in a row.

No issue here. Wish the screen was brighter but at least its the same as my g4

The problems you're describing are physically impossible on a Super AMOLED display... and to say that it has happened to both OP3s you received is just as absurd. The pre-applied screen protector is pretty crappy, but I mean c'mon... Are you one of those guys who returns things with the smallest imperfections, or perceived imperfections in this case?

Do you have any picture of the defect. So far, your issue is uncommon one for OnePlus 3.

Woah there, I have no idea how it is possible to have the problems I have, I know that with lcd sometimes the glue causes the device to be lit unevenly, don't know if that could be the case, but it seemed a little off. I tested this using this video on full brightness: https://youtu.be/vu0mQa2EpS4
While going from. Grey to black, the pixels should all turn of at the same time, or at least, that's how I think it should be on amoled. But this wasn't the case on both devices.
As for the different tint problem, that does bother me a lot more, reading Web with a changing color if you read from left to right isn't that good for the eyes or at least It bothered me.

Here are some pictures, it's quite difficult to recreate on camera like I see them but this gives a general idea of what my issues were with the first device. The first being the screen tint, on the left of the screen it seems to be more red and on the right more green, while this is a Grey background at about 50% brightness. The second is how the screen is unevenly lit while on a solid Grey low brightness background.

I just watched that LCD test video and firstly my eyes hurt from the bright white light secondly I am quite picky and having come from the g4 which I thought had a great screen (few bleed issues though) I am quite happy. I couldn't see anything at all on my unit like you have so maybe it's device specific?
I have noticed this weird thing though and it's when I use MX player pro to watch films. I have been watching the dark night for like the 20th time on th op3 but do notice the skin tones look a little warm and when i increase brightness it gets worst. I think this is a combination of the pentile display and the AMOLED screen with a lower resolution than we would like. I am sure I remember my galaxy note 3 and wife's s5 looking like this also but could be wrong.
Overall it is strange using g4 then using op3 it's hard to explain but they are just different not just LCD / AMOLED but the calibration also. Love the blacks though it's like the phone is off when the screen goes dark. Nice.

So the screen turned black fully at the same time, well there's a logo on screen, but apart from that all black?
I know what you mean by that, I think thats in all screens, not sure, but I had it in both screens but also the problems occurred on them too, maybe that's a feature, I at least won't mind at night when the screen is that low and a bit more warm toned. I saw it on a selfie I got on whatsapp, at night when I got it, I saw her face normal, but when I set the screen brighter, I also saw that the photo also had a background! which was invisible and dark on the lowest brightness.

no issues

Didn't see a logo. Must be blind

Smallest imperfection? He uses the screen all the time and notices that all the time, how is that small imperfection? Also amoled screens are known for the issues he described. All screens have that issue. Just people like you are not good enough to notice it while others notice it easily.

Moto Z Play - Light Bleeding SuperAmoled screen

Just bought a new Zplay 1 week ago. I noticed on dark (not total black) colors that my top right screen corner is a bit brighter that the other parts of the screen. This brightness expands from right too to the middle. My question: is it fixable? Should i ask for a replacement device from Motorola's service (will they accept it?) or stick with this device and live with that? From previous experience from other services, usually i got the older phone back in worst condition than it was before. Anyone else with same problem?
I'm open to suggestions. Thanks.
Btw, fantastic device :fingers-crossed:

Amoled displays cannot have backlight bleeding since they have no backlight. Try downloading a pure black image, turn your brightness to maximum (no auto brightness) and see what you get. If you can still see something, then you might have a defective oled display. Motorola customer service might try to turn you down with the usual "Back light bleed is totally normal (it is normal on IPS LCDs to an extent)", since they more than likely dont know the difference between an IPS LCD and an AMOLED.
Or you could try turning up your brightness to maximum and just activate moto display and see if you can see anything.

On pure blacks i see nothing. The display is perfect. On the other hand i get to see a difference on other colors, mostly darker greys, for example on Chrome's empty tab panel where the color is a bit gray, there the problem can be seen. I'm don't know if this is natural or not. I will upload some pics to get an idea

Probably burn in on the screen from your status bar.. Also check the nav bar area too

Could be screen temp issue. Maybe wasnt calibrated correctly.
Id suggest get a screen test app , bring up a white color and see if that side has a yellow tint. If so its a color temp issue or also could be color distortion. Get a new one.

My moto z plays dispay is slightly on the warmer side (whites are not pure white, a bit of yellowish). Initially i haven't noticed this but when compared this with redmi note 3 then i can see the difference where redmi note 3 colours are more vibrant.Is it normal? Or some issue with the screen?

I just checked m display and it's full black like the deep space, which was obvious since is an AMOLED display and all black pixels turn off to not show anything when they are black.
Ur Moto-Z seems like it was a LCD version lol! Good u get ur money back.

This is my go to app for testing screens, white and grey. Grey is usually the easiest to tell issues on with an amoled. This showed the terrible G-flex 2 panels weakness (greys were horrible on that screen)

Check ur display with total black background...not grey
Amoled usually checked with black background..& see it in dark invirment if any light visable ..if any light visable than ur display is faulty...

AMOLED displays always has to be TOTAL black, since there is not lamp providing light like in LCD and LED panels.

Obviously, there is a problem with the screen. If it does not affect the use, it does not matter, but if you can not accept such a screen, you can replace a new moto z play screen by yourself. This is a maintenance tutorial for moto z play screen. You can watch this to learn how to repair your moto z play.

Probably a defective model you got. Great you got the refund.
