[Video] AMOLED displays terrible purple smudge - Samsung Galaxy S7 Edge Questions and Answers

Whenever I swipe in gallery or basically when something black moves I get a purple tail/smudge following it!
This problem was famous with s4. But people claimed it's gone. But I still have it. Even at maximum brightness.
Anyone else has this issue? Before I bought my phone people told me it doesn't have that issue anymore! It's really anoyying!
EDIT: Video: https://youtu.be/HGsMrZ2o99s

I too have this. Not just on blacks. It's very very visible on whites with black texts too (I was shocked to see this). Simply not the best display right now. My 6P and Note 4 had better displays,

I added a video. Everybody keeps saying this has the Best display
Nobody mentions this. Specially reviews! I think XDA should make an article about this. They're good at spreading the truth like they did with the note 7 lags

I know.. I've got the exact same problem. Maybe worse than yours.
Black text on white backgrounds is even more annoying.

Yeah. Watching movies is a nightmare! As you said it. Text is also anoyying but not as much.
But anyway, what's so great about AMOLED? Colors are not as accurate as iPhone's display. They don't have wider color gamut either. They also have weird rainbow-sh look to them(only the whites look this way too me). And iPhone has IPS!

Strange, watching movies isn't a problem for me, they look wonderful on this screen. Only reading is annoying.
I love everything else about this screen. It's actually a delight to look at. But once you start scrolling through some text, eveything's gone.

Depends on the movies and the brightness.
many things are a nightmare. it's funny some do and some don't. it's mostly dark things surrounded by grey/dark colors. Try watching a dark movie in it. it's all purple smudge!
but some movies like big bang theory have no problem, because it doesn't have much darkness in it! .
I do have to add that I mostly keep my screen brightness low.
I added the video anyway you can see it.

I only have that "problem" with very low brightness. It's very hard to notice for me and I don't have text issues. But I know the reason. When pixels are pure black they are turned off. When the image changes they need to be turned on again which leads to this dark purple issue. It's ,technically speaking, not an issue.

Yeah,i know.i have it even on medium or max

I hate this too, but its nothing new really, been there forever with the AMOLED screens. Its a "shade" from the pixels turning off > on. AMOLED blacks are good simply because it completely turns off the pixel that shows black. With LCD the pixels are always on which gives this "dim-grey" black, but doesn't have this "shade" issue. Making the AMOLED pixels turn on lightning fast would perhaps minimize this problem, I don't know really, but Samsung hasn't solved it yet. Or atleast cared for releasing the tech to the mass

oled screen issue?

can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.
I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.
This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

What color tint does your screen have? Blue, Yellow or Neutral?

In conjunction to the post, "blue tint problem," which isn't really a problem but anyway....
I thought it'd be interesting to create a poll to see where everyone's at with their Vibrants.
Please participate in the poll, it'll be very interesting to see...
So if you're on the blue side or yellow side, obviously submit yours accordingly, however, for neutral that's for those who have calibrated monitors that can get true comparisons to determine if it's neutral.
There's no need to lie here LOL..it's just for fun so the more accurate it is the better. Don't just click neutral if you don't really know for sure. Try comparing your phone first with other Vibrants to be sure.
Here we go!
It's slight blue, but related to viewing angle and screen brightness. Viewing straight on, it's pretty neutral.

I know what you mean. Could the SAMOLED screen perhaps slightly change in its color tone as it warms up?
When I fired up the two Vibrants I have that was turned on for the first time and compared it to my other two which has been in use, the two never been used phones screen looked identical in its tone/shade.
So perhaps over time it does change as it, "breaks in?"
Does anyone know if this blue tint will get better with time? Mine seems to be the same, wondering if I should exchange my phone.
Well, mine is more cyan, though I can understand people calling it blue and it's driving me crazy. Even with brightness all the way up, there is no real white. This issue will likely cause me to return my Vibrant - along with the cheap build quality - as my Nexus screen looks much better and neutral in comparison. Even my wife noticed it immediately though she also has a Nexus.
Neutral, I've compared with monitors and other Vibrants from my T-Mobile store.
The blue should fade over time..sometimes they put in a bit of extra blue to compensate the blue's lower life span..if you want to even it out use a blue background as your home screen for a while and it should even out >.>

Are you sure it will fade? Where did you get that info from, I know wikipedia talks about this and says the same thing, but wikipedia is not really that accurate. Where did you get your info?
I downladed an LCD test app from market, i'm running a constanst blue screen hoping it will help fade out the blue tint a bit. thanks

When compared to mine my wife's had a very strong blue tint to it. Since I ordered ours over the phone I called Tmobile. They overnighted me a replacement without any hassle, I'd give them a call and see what they will do for you.
posted this in the other "blue tint" thread too
"...since the OLED material used to produce blue light degrades significantly more rapidly than the materials that produce other colors, blue light output will decrease relative to the other colors of light...In order to delay the problem, manufacturers bias the colour balance towards blue so that the display initially has an artificially blue tint, leading to complaints of artificial-looking, over-saturated colors..."

I agree, stupidest topic ever. I thought I seena blue tint but now its gone. And as fast as the nexus screen looking nicer...my friend had his over the other day and it looks dull compared to the vibrant.
I guess if your imagining a blue tint, or don't know how to change screen settings them maybe you need a less advanced device.

I guess if you did not receive a defective Vibrant with an extremely blue screen, even with brightness all the way up and power saving mode off, your not qualified to speak for those who did. Of course it would not make sense to you.
i dont know about you guys but every time Ive ever seen a white LED its always had a blueish tint (like automotive LED's) its really not that big of an issue
My display was noticeably blue the moment I turned it on... going to the T-Mobile store today to see if I can get a better unit with a more neutral color temperature.

It matters to some people more than others. If it doesn't bother you then great. It's not really fair to criticize people who are bothered by it--one should have a reasonable expectation for color accuracy of their display, especially for a device so touted as being a multimedia powerhouse.

I have that issue with the blue screen and for some reason I'm the only one who sees it, I work for T-Mobile and I was showing my co-workers that there is a blue tint to the screen and they didn't see it it until I compared it to another phone. I'm also a graphic artist and I guess we see colors that others don't notice cuss we have too that's what we do. I also had a issue with the screen, there was some pixelation on my screen so I exchanged it.

You know, some people here say every Super Amoled has a blue tint. I have to disagree. I've been comparing my vibrant side by side to other vibrants, and the screens vary from phone to phone. Samsung deffinately has some manufacturing inconsistences. Side by side to other Vibrants, my screen has a very visible dark grayish blue tint. Other vibrants have a slight blue/green tint. While other vibrants i've compared to have gorgeus warm whites. 1 vibrant had a very dingy yellow look to all the whites. So this is not in our imagination, the screens vary a lot on these phones.
My cousin just got the vibrant this morning, she had not seen mine. She saw mine this morning and says "why is your screen blue?" Put mine side by side next to hers, and hers has nice warm bright whites. All of our brightness settings were identical.
I'll be exchanging shortly when I have time.

[Q]Whitelevels and screen sharpness

I have only seen 4 galaxy tab 7.7's so far and I noticed all 4 of them really have bad white levels as compared to my galaxy note, disabled the auto power saving and there is a difference in white levels but its still not even close to the galaxy note at the same brightness level. Even at brightness 25% on the note the vs 100% on the tab 7.7shows 'dimmer'whites. This is not a rant but I'm just asking if the screens are calibrated that way or should I keep looking?
Also I noticed that the mdine engine oon the tab provides oversharpening to a lot of my photos and its so obvious and makes the images look bd, supercurio has the same findings.
It is a pretty big screen so it may be they limited the brightnes to save battery power. While the claim is that OLED takes less power than LCD that is not always true. When displaying white, OLED tech uses like 4X as much power as LCD. The power saving comes in when displaying images with medium to darker colors.
What is the "mdine engine"? Is this something that can be bypassed by using a different picture viewing app?
It is amazing how Samsung seems to always add some crappy image "enhancement" like DnIE or such crap. Why can't they just leave our images alone, as we meant them to be? It is freakin' OLED man. You don't need any contrast or sharpness enhancement you knuckleheads! OLED by nature is sharp and has great contrast! Duh!
I don't know. My 7.7 is super bright, sharp and with way warmer colors than my Note.

I'm thinking the samr thing that samsung might ne limiting how bright the whites can go duebto the screen size but based on what I've seen on samoleds some screens juat put out better white levels, not really brighter but whiter.
For the mdine its running system wide.

Yes I believe so, Supercurio knows more about that stuff.
EDIT:
simulated example done in photoshop, anyone with the tab7.7 and better photoshop skills feel free to redo this simulated image
Perhaps one of the other reason that the 7.7's screen isn't quite as bright, apart from the obvious power saving reasons, is an effort to possibly reduce the OLED degradation (burn-in) effect.
Either way, although I certainly noticed out of the box that my 7.7 wasn't as bright as my Note (or even my GS2 for that matter!), I was never really bothered by it because (especially when you use movie mode) the colour reproduction is very accurate, and paired up with the contrast levels, it's still fantastic!
I guess, to me, white doesn't necessarily mean I need to put on a pair of sunglasses while looking at my screen lol!
I just wanted to know if the norm has lower white levels, what bothers me more is added sharpening on some images.

Yellowish? Not at all! At least not with my unit anyway. Sure it makes the screen generally warmer in colour, but IMO, more than anything, it makes the colours look more accurate and natural.

Well ever since the Galaxy S changing the color mode to movie mode gives a yellowish cast, this is probably dependent on the calibration on the screen we get in the first place. I saw a friend's Tab7.7 the other day and his white levels were really brighter than my Galaxy Note. FWIW, its still a luck of the draw when it comes to color calibration on the screen. But thanks for that tip, when I'll purchase the Tab I'll make sure to also check out movie mode and see if it hits my requirements.

Very bright noticed the same with the Note ,
Nexus was somewhat easier on the eyes at night,
But probably like you I like a very dim screen at night.
When the brightness is turned all the way down on the 7.7,
is any banding or other issues seen like many report on the Note?
Blacks are black I'm sure but how are greys that are near black.
On the Nexus they were fine, but on the Notes I seen they could have been darker?

I do not believe a Note with a good screen exists

Please prove me wrong!
Anyone have any links to videos showing a Note rendering dark grays correctly?
watch the demovideo on your note.
The dozens of reviews which acknowledge how good the screen is proves you wrong.
Pfffff. Tests with Samsung handselected devices. Or do you think that Samsung will send defectiv devices to the testers?
The note I got from bell has no screen issues at all.

Mine is fine with some tweaks. Primarily -40% contrast. I can see down to '2' on that test image. I also notice little or no blotchiness in dark videos any more, although I did before adjustment.
It's a software issue IMO.

I share the same sentiment as no one with a 'perfect screen' has shared it. The best I've seen is one w/o any black clipping what so ever since his gamma test result is similar to a Galaxy S2 but I do see a few visible horizontal lines on a grey screen. Its not perfect but its with in specifications aside from the lines.

To the unwise it may seem incorrect since they are only looking at the smaller picture and dont really have a clue on what this 'objective' test is for, let me give a real life example:
Using the Kindle application for reading ebooks gives you the option to use a black background now some screens have very visible blotches even if there is a text on the screen and they are become unoticeable when there is a text above them, this of course matters to someone who reads ebooks in their bedrooms w/o any external light source or to someone who watches movies like me. You see if we ask someone to open kindle and load up something and do this and do that, it makes the 'testing' more subjective rather than just test it in a pitch black room with a black image displayed.
These tests may sound silly to others but its the best way to get an objective result, remember people theres a difference between 'its not there' and 'i dont notice it with normal usage'.
here is an example that hopefully may enlighten you people with self proclaimed perfect screens so you may understand why its so difficult for others to accept such screen exists because with several replacements they havent seen one yet and people always claim that defects are the extreme minority, if its true then no one should need more than 2 replacements to get these perfect screens, correct?
It is also common for others to be dismissive of any screen related issues, you can be dismissive all you want provided you show an objective result. till then your screen is just as flawed as everyone else.

Are those dark rings one of the issues that everyone is complaining about? If so, I'll have to look at my unit, but I suppose I've just been extremely lucky. I have yet to notice any issues. That's not to say there aren't any issues with my device (possibly), if I look really hard, in very specific conditions
I do not have any black blotches or whatever.
One of the issue I have is the gray screen. It has somesort of texture on it but it's tolerable since it looks like a texturized wallpaper. No problems with playing videos at all, everything looks crisp and clear. So far I am enjoying it.
Also, another issue is the camera. When I am around those long florescent lights, there seems to be some wavy things on my screen. Even on video. I guess I got to avoid those lights in taking pictures. Haha.

That Image i used came from the Tab7.7 forums which shows the issue and practical scenario at the same time. Its an example of the darker blotches in blacks, not really the main issue on the Galaxy Note but one of the many possible yet rare issue.
On my end, my first screen had some blotches but they were not visible when I watch a movie or read an ebook from the kindle app, the 2nd screen I had did have a home button sized like blotch at the bottom which was visible when reading ebooks unless a text is close to it, in movies/shows it is only visible when the entire screen goes black.

Using the Kindle application for reading ebooks gives you the option to use a black background now some screens have very visible blotches even if there is a text on the screen and they are become unoticeable when there is a text above them, this of course matters to someone who reads ebooks in their bedrooms w/o any external light source or to someone who watches movies like me. You see if we ask someone to open kindle and load up something and do this and do that, it makes the 'testing' more subjective rather than just test it in a pitch black room with a black image displayed.

Once again, I guess I have been extremely lucky with both my Note and my 7.7, because I have yet to notice any of these issues with either
Black clipping and banding = software. Therefore, irrelevant from a hardware perspective.
The splotches that you see in the most dark of conditions are the artifacts of the manufacturing process. Under normal 0% brightness (without using additional apps like screen adjuster) you will not be able to see these things assuming you've got a good screen.
The only things you need to look out for is color unevenness and brightness unevenness and in some cases, the manufacturing process is so prominent that it seeps into the normal brightness (0% and up range) and it is visible.
The fastest way to tell if there is something wrong is to turn off all auto-lcd power management, set the brightness to 0%, and to simply pull down the notification menu and view it in a dark place. That'll reveal most of the problems that you might find in a day to day situation. If you see nothing there and the screen looks crisp, don't bother looking for more. They will not appear in normal real-world situations.
No blotches on mine. Very happy with the quality. The color profile seems nicer than on my i9100. The only screen I had with noticeable blotches (only seen at full darkness) was on my T989.
So ya, very happy with my Note's screen. White International N7000
The witch hunt started with the original sgs and continues with the note.
Im on my second note plus a screen replacement and screens are flawless. Yes there is somme banding on all of amoled screens. Its partially software because running ics alpha build, most of the banding is gone.

Display issues

Hello guys, suddenly I'm having display issues on my k20. I've attached a link to the video, when i pull down the notification bar, look how the blacks are loading a bit late. When i turn off dark mode, i see no issues like this, it's just the beautiful display again. Even i had same issues with my dark wallpaper. Please check, if you've same issues. I'm really concerned about it. Also, this maybe screen flickering but when i increased brightness, the issue didn't disappear, it was still persistent but at lower levels.

That's normal behavior for amoled displays.
1st: If this is the display problem, how can you expect we can see this on a screen capture??
2nd (probably because of the 1st): I can't see anything wrong.
3rd: I have no display issues at all.

Can't you see that voilet-ish colour instead of black when I'm swiftly moving the notification bar? It's clearly visible in video, you might want to check again.
Nope, watched it at least 5 times, on my PC and my 9T. Can't see anything peculiar.
I can not see anything wrong or violet at all. Am playing this on my computer at 1080 resolution and 0.25 playback speed and there is nothing to see.
If your screen is faulty, we are not able to see it on video you have shared with us of course
DAMN IT! Even i see nothing from my laptop
I think I'm having screen issues, only when its dark mode, else the screen is working absolutely fine!
I need to get to the service center ASAP! :crying:
Edit: Guys can you try doing the same and look if the issue is persistent in your screen too?! It would really be helpful for me.

It's normal for OLED panels, some are better, some worse. My phone has it too. No need to go to the service center.
I too have it brother. Dark mode has it normal mode doesn't. It can also be noticed if you open youtube and scroll back and forth quickly. The blacks seem to be spilling or streching. I saw that on your video and I don't know if it is normal or not but i too have that and wanted to ask someone about that.

People are claiming this to be normal, but after searching a lot i got to know these kind of issues come after 1-2years, not in a week or month. So I'm trying my best to replace my device or get the screen changed. I don't understand why Xiaomi is keeping the colours to pure blacks when they know their displays are facing smearing issues. I hope someone just changes that pure black colour to very dark grey colour, system widely. Some developer tested(on OP7 pro) the battery consumption difference with pure black and dark grey and it turned out that, dark grey consumes only 0.067% more power than dark inky blacks. I'm humbly requesting developers to change the colour, or at least have an option for the same.
My display when there is low light, the brightness is set to low and the image I see on the display is darkish I can see a vertical line at the left side of the display, is this normal or should I return It?
It's normal for Amoled screens (from first day of use). Just search for Amoled black smearing and you'll find a lot of videos and articles. S10 has it, iPhones have it too.

I have faint vertical lines on the right of the display when the brightness is low which is how I normally use it. I also have black smearing on pitch black to dark color transition. I think thats normal, it doesn't really bother me all that much.
The best way to reproduce this issue is turn off brightness to minimum and turn on reading mode to max. Then you'll see delay of displaying some colors (mostly gray)

My k20 has this issue and it's annoying that after paying for a flagship killer, we just got a cheap display which is not just low in quality but has these issue in dark mode which i think most of us use. Interestingly when i record this from screen recorder,it doesn't show up much but the same can be seen visually. So, this is definitely an issue that redmi is trying to let go.

As you "record from screen recorder" you do not record from the screen as you may like to think. You capture the video signal BEFORE it gets to the screen. So any imperfections caused by the amoled screen do not show up on a screen capture.
Anyway, this is a normal weakness with all amoled screens that I have seen.
It is soooo annoying when in dark mode at low brightness, I feel like I couldn't stand it anymore. The worst experience of display usage ever.
Maybe with DC dimming update that might happen someday, the issue won't be as intrusive and pronounce as it is right now. But whenn???
UPDATE:
So I found a workaround for this issue with an app. It's called Screen Balance. Basically it adds a filter overlay on your screen (ineffective on notification panel, because android restriction). Set it to either flourescent or flourescent (warm) at 15% strength minimum, and both brightness and contrast at 100%. You won't see perfect black anymore, but very close to that and no smearing effects visible unless you're really trying to.
I've bought Mi 9T Pro and have the same issue (also see it in your video). Did you fixed that?
