[Samsung Galaxy S9+ Questions & Answers] th.android:
I'm already on my 2nd handset and the issue seems quite widespread. I don't know whether it's worth going through another swap (likely to be the same).

Can anybody confirm if Samsung officially said they're working on a fix? I've read it somewhere but it was vague and could be just a rumor.
[Samsung Galaxy S9+ Questions & Answers] Toss3:
Same issue here. Please don't forget to contact Samsung about the issue; they cannot fix what they don't know is a problem! Remember to post on FB and Twitter as well, as they really don't like bad PR.

Worse? Strange.... I can't reproduce it on my Pixel 2 XL...
[Samsung Galaxy S9+ Questions & Answers] Toss3:
If you're inside the return window I'd do it and wait for an official response or update. Odds are this is never going to be fixed and waiting would probably let you buy the phone cheaper once, and if, they ever decide to release an update. :good: Do let them know why you are returning it!
[Samsung Galaxy S9+ Questions & Answers] Galaxo60:
The video I posted addresses the problem clearly, and it was a widely spread problem for everyone.

After December's update, they put a patch and minimized the problem, so maybe that's why you don't notice it.

Returning the phone won't make a difference, because is a calibration problem. Calibration can be changed through software.

But is true that we need to give visibility to the issue so Samsung can fix it, the same as Google did with the Pixel 2 XL when everybody started to complain about it.

:highfive:

Contacted Andrei of Anandtech on twitter and while his S9 is fine, he'll check his S9+ and if it too suffers from it (which it most likely does), he'll mention it in his review and this will hopefully get some attention from Samsung! :highfive:
[Samsung Galaxy S9+ Questions & Answers] Toss3:
Another update: Samsung are currently investigating the issue, so if all goes well we should probably see a fix sooner rather than later.

[Samsung Galaxy S9+ Questions & Answers] Toss3:
Samsung. Contacted them via Twitter, FB, email, and phone, and they finally told me they had escalated the issue to the software team and are investigating. Took some convincing, but they finally gave in. :highfive:
[Samsung Galaxy S9+ Questions & Answers] Chris_c81:
Excellent. I've also been supplying their tech department via email, with reference conversations across XDA, Reddit and other forums. Sooner they're looking in to it at depth, sooner we'll get a fix or announcement at the very least.

Same issue. S9+ Exynos. Tried Screen balance app which definitely helps but the issue is still there somewhat when watching dark videos or gifs etc.
[Samsung Galaxy S9+ Questions & Answers] th.android:
I'm just wondering if there is a single S9+ without this issue.

Good to know whether it's worth pursuing the tech support process multiple times until you get a proper device or give up and wait an official response from Samsung.

After receiving my replacement device (which turned out also to be faulty), I was told by the UK Tech Support I need to go to a Samsung Support Centre in person to show them the issue and it's up to them to decide what to do. They said swapping the device through a courrier service is no longer an option after the 1st replacement. At least I will make them aware of the issue first hand and hopefully try some handsets there to check if they have it.

I just hope they don't give me some stupid excuse like "it's intended to look this way".

I'll update here what happened.

No, we can't.
[Samsung Galaxy S9+ Questions & Answers] Galaxo60:
Just ask for a replacement if you don't mind that much the black crush problem.

Otherwise, I guess you should look into some other brand, because we don't know if this will persist through future models.

I got the 5t, it sucks because it blocks certain apps to run smoothly like Samsung Health. The pathetic camera is a big no anyways. Moreover they launch a new version like the "T" like after 4 months so it sucks. Every now and then it shows that it is a chinese oem. To fix simple issues, which occur for no apparent reason, a noob gotta do these things in the 5t

So I tested the camera again, and it look's like the problem with purple borders is noticable in absolute dark( I try to photo the stars) - and ISO is set to 1250, and automatical mode. When I use PRO mode- there you can set ISO max. only to 800- the problem with borders isn't ther. Problem with dark super slow is also there when sun is shining or when are you inside bulding... Can someone test this problems for my? If only I have the problem or what...thnx

Try to elaborate a bit more. Tell us exactly what we need to do. Would be happy to report back.
[Samsung Galaxy S9+ Questions & Answers] arnes_king:
That is normal for super slow motion, you need daylight in order to get good shots, at night it is too dark for anything.
[Samsung Galaxy S9+ Questions & Answers] civomt:
When I take photo at night, (and ISO is automatically set to 1250). The photos have pink artefacts, the most around the bordes. But when I manualy set the ISO to 800, the problem isn't there. When I compare photos to note 8, with some night scenery, both on automatic settings, the S9+ photos are deffinetly with purple artefacts...You can try make photo in the night (or lay phone on the table and create photo) and when you go to the dark room, you should see purple artefacts. It is most noticable when you have bringhtness on the maximum.

---------- Post added at 11:06 PM ---------- Previous post was at 11:03 PM ----------

I create the super slowmotion video on daylight outside. The video is really dark and bad quality. I switch between normal video and super slow mo- and it looks lot of darker.

Edit:

Here is talking about problem, Samsung notice, he know about that and he is working on the Update.

Lots of talk between forum members and Samsung and some say they are aware and working on an update whereas other say Samsung acknowledged the problem and no solutions.

[Samsung Galaxy S9+ Questions & Answers] ingenious247:
Sorry to dash anyone's hopes on this, but the problem lies in the Android coding itself, it's not a Samsung issue. Same thing happened several times over the last few years.. in the past, I used to think it was intentional on Google's part to make AMOLED screens looks worse than the Nexus in order to drive people to Google phones.. but now that they are using AMOLED panels, it makes absolutely ZERO sense Google's Android team would not take AMOLED into consideration when coding the newest iteration of Android (in this case, Oreo). Pathetic that they continue to overlook this issue.

If any one got the April security update from samsung,please comment on whether it fixed any of our issues.
[Samsung Galaxy S9+ Questions & Answers] th.android:
I used to think the same thing, that Oreo was the problem because of Pixel 2 similar issues. However, when my S8 was updated to Oreo, it didn't exhibit the black crush problem. More importantly, the regular size S9 doesn't seem to have this problem at all.

Also, the severity of black crush seems to be variable between different units. My current unit is noticeably worse than the previous. That makes it more of a hardware issue unfortunately than software.
[Samsung Galaxy S9+ Questions & Answers] alicia343:
S9+ Asia Region has the same problem

I and my friend s9+ which 1 I bought from singapore and 1 from Vietnam have the same problem. When the screen brightness is low, black area will become pixelate :crying:

That's for the SD845 model. There's a new update out for the Exynos S9, but hasn't yet been made available for the S9+ for some reason.
[Samsung Galaxy S9+ Questions & Answers] andy7a:
I belive this is not for all S9+ models in the market since this thread is actually not so populated and other similar threads on other sites barely have a reply if not at all. So I guess we are the unlucky ones with some factory fault units and the only thing we can do about it is to return the phones (if you still are eligible) or just live with this since it seems clearly to be an hardware error. I tried screen balance and it is improved a bit but not completely fault free and also you will lose deep blacks. If you set RGB range to 4% you will get deep blacks again but the black crush returns. I am very skeptical of Samsung to solve this by a Software update.

Conclusion: you live with it or return it. I don't think it will be fixed. Or if you are lucky and win the lottery you might get a fault free phone.
[Samsung Galaxy S9+ Questions & Answers] Maij19:
I have the s9 plus and my daughter has the s9, both have black crush/gradient banding issues. They are equally as bad/noticeable...I have started warranty exchanges on both...First, I contacted Samsung and they told me to take them to a Samsung authorized fix-it dealer. They told me they couldn't correct the issue after having our phones for 4 hours. They had Samsung replacement displays on hand but did not think it would help because they didn't think the display was the problem. They thought it was the logic board. With this being said I don't know how reliable or knowledgeable this person really is. I called Samsung back with this info and they asked me to send the phones in for repair which would mean to be w/out a phone for who knows how long. That's obviously a last resort so I did a warranty exchange thru my carrier. Either way, trying to work directly with Samsung on this issue was a big waste of time!
[Samsung Galaxy S9+ Questions & Answers] andy7a:
Please inform if new devices have same issues. Thanks.
[Samsung Galaxy S9+ Questions & Answers] Maij19:
Yeah, no problem, I'm worried about that too...
[Samsung Galaxy S9+ Questions & Answers] Galaxo60:
Just a little news not directly related to the S9+:

I just bought also a P20 Pro and it has the same problem, but is slightly less noticeable.

Problem with this P20 Pro is that black color in really low brightness becomes a total crush in the whole screen, like a grainy picture.

So I guess is an AMOLED problem of this generation, or we are getting more picky and we notice more and more things.

;)
[Samsung Galaxy S9+ Questions & Answers] th.android:
I'm not convinced this is an "AMOLED issue" at all.

Last week I purchased an iPhone X to use as a secondary device. As we are all aware, iPhone X has an OLED panel manufactured by Samsung.

I did a lot of testing under low light conditions and I can report with confidence that video playback in dark scenes is absolutely flawless even

with the bare minimum brightness setting

. There is no sign of black crush or any other sort of visible artifact. And I'd like to emphasize that it is not like there is some but it's barely noticeable, there is absolutely

no sign of it

.

All I'm saying, it is a shame really for Samsung being so careful with a competitor's device and not with their own frigging flagship. And also, stop people believing this is somehow "normal" with OLED screens.
[Samsung Galaxy S9+ Questions & Answers] arnes_king:
Does anyone of you face the issue not in dark but in bright environment?

I do not have any black cruch in dark environment and brightness down, but when the sun is shining really bright and the auto brightness level goes to MAX (into the red zone) I start seeing black crush, but it seems a little different then the one I saw in this thread. I see it only on some parts where black and white color is close to each other, the white makes like a halo effect and "tries to connect" to the other white areas over the black.
[Samsung Galaxy S9+ Questions & Answers] garret1976:
It is an Oled issue for years. Every Oled has it but it's not always noticable like you see on S9+. (Pixel 2 XL was even worse before update)

According to Anandtech (and some others), iPhone X has is but Apple is using a very fine dithering filter to mask the problem. So Samsung could use the same technique I think.

https://www.anandtech.com/show/12520/the-galaxy-s9-review/7

But I agree that it's a shame and Samsung should definitly deliver the best quality possible in their flagship.
[Samsung Galaxy S9+ Questions & Answers] Chirag22ster:
After going through the three pics, I guess i am pretty sure i dont have the issue. However, comments of seniors will be appreciated if I am making any mistake to understand the issue.

Apologize for my earlier posts where i have mentioned that my unit has the issue.

Attaching the two pics of my cellphone which were clicked on my wife's Note 8.

One pic is the photograph of the image of having the issue.

The other one is the photograph of the screen shot of the actual image. Phew its so confusing.

Should i do any other test to confirm if my phone has the issue?
[Samsung Galaxy S9+ Questions & Answers] DemonSoul:
you need to lower you're brightness , is it at like 20/30%, if you have it at those levels, and its like that then you good
[Samsung Galaxy S9+ Questions & Answers] pieces of cake:
Compared to my wife's S7, the difference at 30% brightness is noticeable but not unbearable now. Regardless, the S9+'s picture at higher brightness levels (~70-100%) is FAR superior. I don't watch much video at anything other than high brightness anyway, so I can't say I give a $h!7 anymore.
[Samsung Galaxy S9+ Questions & Answers] arnes_king:
Now after switching back to the original theme it is not visible on bright daylight and brightness at max. When switching to the black theme it gets really visible, but as said only on max brightness.

Would someone of you test this out? download a black theme, I was using "High contrast theme II", and go out to get the auto brightness kick to max, or set it manually. After that launch the keyboard, one handed mode or scroll through the menus, you should be able to notice it.

So this issue is not only visible on min brightness but also on max, but people did not notice it because you have to have a black theme!
[Samsung Galaxy S9+ Questions & Answers] s0nixx:
Hi, I purchased a new S9+ and I seem to have the same problem. It's most noticeable in dark room with low brightness. Mostly in videos. When I play some HDR videos there is no "black crush".

I wonder if this is a software issue? So many people have this and who don't I think just didn't notice it.
[Samsung Galaxy S9+ Questions & Answers] bandit_knight:
I can observe it on my device. When the super bright mode kicks in I can see weird flickering and halos for example while scrolling images containing contrasting elements. A Samsung service point here in Poland claimed it's normal and that I believe is plain bull****. I saw no such effects on my old S8.
[Samsung Galaxy S9+ Questions & Answers] shaggyskunk:
There was a Bug Fix & Security Patch OTA update for Rogers a few days ago (I'm still waiting to receive my S9+ (SM-G965W) So I don't know if this update has fixed the issue for those who have it?

Sent from my SM-G955W ??
[Samsung Galaxy S9+ Questions & Answers] s0nixx:
When I take a screenshot of the problem I can view it on the device, zoom in and out on the pixelated blacks. When I tried to look at that screenshot on another phone (IPS screen) you can barely notice it while fully zoomed in on the spot.

So that means it's a software issue?

Also could someone who have a S9+ put the pink infinity wallpaper on then go in a completely dark room unlock the phone and slowly swipe up to open and close the app drawer? Do you see something similar to what I have here in the picture? You have to swipe it very slowly and look to the upper left corner. It should be visible. It appears and disappears when swiping. But it stays there when you have the app drawer open. To notice it as I said you have to be in very dark room.
[Samsung Galaxy S9+ Questions & Answers] DemonSoul:
Still anything fixed?
[Samsung Galaxy S9+ Questions & Answers] ssj100:
I can confirm this issue with the wallpaper, but it's not just the "pink infinity" one - all the default ones have them to some extent (some less obvious than others, and in different locations of the wallpaper). I think the "grey infinity" one has it least. A better way to test for this issue is to tap the clock/time at the lockscreen, which should bring up the time with seconds showing, and also cause the whole screen to "blur" - this is a better/clearer way to test for the issue as there aren't any app icons in the way.

Unfortunately this issue is still present even with the "quality of Wallpaper has been improved" patch, although I think it's slightly better.
[Samsung Galaxy S9+ Questions & Answers] pieces of cake:
Are you seriously at the point where you're concerned with an issue that's specific to the very top-left corner of the display and that you only notice when making a deliberately slow gesture with a particular wallpaper while in a "very dark room?"

Say that out loud and listen to yourself. Sounds a bit ridiculous, doesn't it?
[Samsung Galaxy S9+ Questions & Answers] ssj100:
I wouldn't be surprised if there are people who do care about this. But perhaps the more important thing is that it probably ties in with the black crush effect in videos that many people here are "concerned" about - another person could easily respond to this entire thread with what you wrote, but then different people have different thresholds. Some people can't even afford to buy a smartphone in order to be "concerned" about anything reported in this thread, but then that's not the point of threads like this.
[Samsung Galaxy S9+ Questions & Answers] s0nixx:
Of course, I'm concerned. Since other people have that it suggests that Samsung own wallpapers are f** up. I'm not talking about wallpapers only since I have this in videos also. Samsung probably skipped quality control on the S9 :D

Since in my country I can't simply exchange the device only claim warranty I will wait for a month or two, If they don't fix it I just hand it to the repair office.

Replacing it seems useless because many people already did it and got no results. And those who say they don't have the issue either don't see it or just don't care.

I was thinking about going to different shops to look at the s9+ they have there and compare to mine. But that's useless also since the lighting there is way to bright to see the issue.
[Samsung Galaxy S9+ Questions & Answers] rodrigoduarteh:
I have a g9650, will it be that if I install the latest software version manually this problem with colors is resolved? my s9Plus also has this problem.
[Samsung Galaxy S9+ Questions & Answers] Toss3:
Issue is fixed in the latest firmware: ARD1!

EDIT: Now before people are going to get their hopes up, it is much better, but not completely fixed. They fixed the calibration so that grays now appear gray instead of green while mitigating some black crush at lower brightness levels -> this means you'll still see black streaks and the like in trailers such as black panther when transitioning from complete black to gray (this is a hardware issue that they cannot fix in software alone).

Is this not the April Google security update ? I've downloaded it and it's made no difference. 61.33mb update
[Samsung Galaxy S9+ Questions & Answers] Toss3:
Yes. 61.33 mb is plenty for a slight calibration modification. There's definitely a difference for me; no more green tint at lower brightness levels (there's still a rather large gap between grays at RGB(8,8,8) and (9,9,9) so that's not going away, but grays no longer appear green).
