[Samsung Galaxy S9+ Questions & Answers] Toss3:
Some more pics (tried to capture it on video, but it's almost impossible without a decent dslr capable of high iso video):

As we can see from the pics the S9+ actually suffers from less black crush than the S7, but the latter still looks much better (no green mess).
[Samsung Galaxy S9+ Questions & Answers] trenzterra:
Mine is the opposite of yours, lol. My S9+ suffers more black crush but less green mess than my S7 edge.
[Samsung Galaxy S9+ Questions & Answers] Toss3:
Wait you don't have any of the green mess when watching the black panther trailer? Could you post a pic of the same spots? :confused:
[Samsung Galaxy S9+ Questions & Answers] trenzterra:
Give me the exact timings and I'll test it for you.

---------- Post added at 05:42 PM ---------- Previous post was at 05:27 PM ----------

Here's a video I took with the S9+ on top and the S7 edge at the bottom with my Sony A6500 camera. Room was virtually dark (only some light shining in from the corridor which I cannot avoid). Screen brightness was set to around 5%.

On closer inspection, the S9+ does look very slightly greener. But not as bad as yours.

EDIT: If it doesn't load, see my video here: https://www.youtube.com/watch?v=OrY2iVQht3k&feature=youtu.be

Attached the screenshots below. :)
[Samsung Galaxy S9+ Questions & Answers] madvinegar:
At least after the latest update, the live wallpaper is very nice.
[Samsung Galaxy S9+ Questions & Answers] trenzterra:
Hi Toss3, I'll update with your screenshots soon.

Someone mentioned Black Panther at 0:44. Mine looks okay as far as I can tell:

Someone also mentioned the cross with the glow. Here's my comparison, S9+ at top, S7edge at bottom. The 'olive green' appears on my S7edge instead.

Here's the Black Panther trailer, re-shot at ~40% brightness:

Here's a Netflix film (Friends From College) where I discover differences between the S9+ (top) and S7edge, with the S7edge being brighter and less crushed even with the same screen brightness:

[youtube]GlLZeiKatPs[/youtube]

See https://www.youtube.com/watch?v=GlLZeiKatPs&feature=youtu.be if embed doesn't work. See especially 0:25 of the video. The S9+ is crushed but the S7edge isn't. Given the Black Panther trailer looks exactly the same on the S9+ and S7edge for me, I suspect Netflix is serving up a different version of the video for me.

As I mentioned before, I tried hooking up my S9+ to my Dell monitor as a test. Here's how it looks on my Dell monitor:

https://www.youtube.com/watch?v=wRqwpcYDNDk&feature=youtu.be

You can't see the 'black crush' here, but if you look closely, you can see evidence of black dithering that doesn't appear on the S7edge (instead, the S7edge loads up a more pixelated video instead but no black dithering).

---------- Post added at 06:28 PM ---------- Previous post was at 06:11 PM ----------

As requested, the screenshots. Shot at about ~30-40% brightness (3rd to 4th icon in landscape mode). S9+ on top, S7edge on bottom. See my IMGUR post here with all the screenshots:

[Samsung Galaxy S9+ Questions & Answers] coolguy949:
Both were manufactured in Korea. Is there a way to check if there's a difference in screen hardware? I remember back in the day, some Nexus devices had different screen OEMs. This new S9+ shows manufacturing date of 02/18/18. I beleive my previous device was the same.

---------- Post added at 11:00 AM ---------- Previous post was at 10:42 AM ----------

My first S9+ looked just like this. Almost unwatchable. With my replacement, the only flaws I can now find in Black Panther are around 0:44 where his jacket collar is a little crushed and gray, some of the backgrounds like at 1:28 and the glow around the text the flies on the screen. I don't get a lot of the green mess anymore but some of it is still present (more grayish now). The "When We First Met" trailer still has some of the weird gray blobs on the characters' hair (they used to be greenish) in some dark scenes but it's much harder to see. I really have to look closely. Black crush is reduced by not totally gone. I can see it in some of the dark background. It transitions to black in a kind of pixelated way (dithering?). It all still doesn't look right but it has improved with my new device. Thankfully it's harder to see but it still bugs me a bit.
[Samsung Galaxy S9+ Questions & Answers] garret1976:
I don't have a green mess. I can only compare to S8 and S9+ looks identical color wise only S9+ image is darker or more black in the dark areas and more noticeable black crush.

Edit: checked again but I was wrong. S9+ is a little more greenish than S8. I would say S8 is a bit reddish.
[Samsung Galaxy S9+ Questions & Answers] Cristi10:
So let me get this straight. Only the plus suffers froms this? Not the regular one? I think the same happened to me with the s7 and s7 edge, i had the egde and compared it one day with a regular one and noticed the ghosting issue was more visible on my edge. Now with the s9, i had the regular one first then returned it and upgraded to the plus. And i think the s9 didn't had the ghosting issue that amoleds have and this black crush but i am not sure because i had the regular one only for like 2 days. I don't really now what to say about all this, hopefully can be fixed.
[Samsung Galaxy S9+ Questions & Answers] Chris_c81:
I know some of you are sceptical about conversations held privately, but I assure you I am passing on legitimate communication I'm holding with Samsung tech support.

You may want to return your handsets...

This was in response to me emailing them links to this topic where some have stated a replacement has fixed the problem.

I've now replied asking whether I can be confident that should I go through with a replacement, the new handset would not have the fault.
[Samsung Galaxy S9+ Questions & Answers] Toss3:
Did you test it out in a completely blacked out room at the lowest brightness setting? :confused: The screen is fine when you set the brightness to >30%.
[Samsung Galaxy S9+ Questions & Answers] ssking:
Galaxy S8 updated to android oreo, just noticed the gradient issue on the default wp
[Samsung Galaxy S9+ Questions & Answers] th.android:
So Samsung's solution for the infinity wallpapers was actually making them look more dull and washed out... Can't wait to see their solution for the black crush.
[Samsung Galaxy S9+ Questions & Answers] Lenkbron:
Where are the links with people saying that a replacement fixed it?

All I read is that some people said it is better, but what is better? Better can mean it is still not good, maybe if it is a defective display there are different degrees how pronounced the issue is.

I would believe it if people said they definitely don't have it, or that it is on the same level as an S7, S8.

Still interesting that someone from the support says it is a hardware defect. What would they do to fix it if you send it in for repair? Just change the display?

If it is a hardware defect, I would definitely return it, but I'm not sure if I would go for a replacement, since it still will be lottery.
[Samsung Galaxy S9+ Questions & Answers] BlackBird_666:
Yesterday I got the new update G965FXXU1ARCC and then I played some videos on Netflix and Youtube at first black crush was horrible but then later in the evening I played the same videos on Netflix and Youtube funny enough no black crush. I even compared it with an S8 Plus.

Compared to a S8 Plus, the brightness is less in S9 Plus, which is the only problem I have with my device now.

I am really confused...

Update

Black crush is still present but barely noticeable
[Samsung Galaxy S9+ Questions & Answers] Avohkah Tamer:
I know this is the subforum for the Plus variant, but since there's no equivalent topic in the S9 boards, can anyone here with both both variants confirm whether the normal S9 has the crushed blacks issue?
[Samsung Galaxy S9+ Questions & Answers] Chris_c81:
What I meant is links to the comments in this thread in recent days by some suggesting the issue was not present or not as bad on replacement unit.

But it's as you say to be honest, nobody has stated with any conviction that the replacement does not suffer the issue.
[Samsung Galaxy S9+ Questions & Answers] Chris_c81:
I've an S9 and an S9+ in my household. I can confirm that the S9 does not have the problem.

Many others have also confirmed this in the thread.
[Samsung Galaxy S9+ Questions & Answers] Lenkbron:
And in addition the that, we also now have different statements from the Samsung support, one saying it's a hardware defect and others saying it's software.

Have they offered you further details on what they would do on the hardware side to fix it?
[Samsung Galaxy S9+ Questions & Answers] Chris_c81:
I've asked the question. Awaiting reply.
[Samsung Galaxy S9+ Questions & Answers] tlbland0426:
I have an unlocked S9+ and I've tried to follow all the samples on here to try and replicate the issue on mine, tried the :44 mark on the Black Panther trailer, started episode 1 of Marco Polo. Either I'm blind or mine doesn't appear to suffer from this issue because I can't see any issues. I mean it looks pretty obvious from some of the post, can't miss it but maybe I got a good one....or in the next few days it will magically appear.
[Samsung Galaxy S9+ Questions & Answers] Lenkbron:
Have you tried it in low light situations with low brightness settings on the S9+?

And regarding Marco Polo, look for it between minute 3 and 4 on the first episode.
[Samsung Galaxy S9+ Questions & Answers] tlbland0426:
Yep, totally saw it that time...well ****.
[Samsung Galaxy S9+ Questions & Answers] Lenkbron:
I think that scenes in Marco Polo look even worse than the Black Panther trailer. On my S7 Edge I can watch it without any major complaints.
[Samsung Galaxy S9+ Questions & Answers] BlackBird_666:
Marco Polo and Black Panther trailer for me was hit and miss! I don't know how to explain this, there are times I don't see black crush and there are times I see black crush even at 30%-40% brightness (watching the same clip).

I've contacted samsung and they have advised me to take my device to a service centre here in Kuwait to get it checked.
[Samsung Galaxy S9+ Questions & Answers] DemonSoul:
Anything? Mean while I went to get my new phone, and no stock yet need to wait another week, god bless. If I get this problem again on the New one, I'll probably ask for money back, and get other phone, (one plus 6?)because it looks horrible the black and what pisses me off more is them saying that there is no issue with the screen on the store (fnac) , when doing the screen tests, you don't say sherlock f holmes, I even said that people had some oficial Samsung reply about this, and they said that forums doesn't mean anything.... Well ok then? Love the phone but this is just unacceptable on a freaking 900 mobile!
[Samsung Galaxy S9+ Questions & Answers] Chris_c81:
Nothing yet. Usually takes a good 48 hours for them to reply.
[Samsung Galaxy S9+ Questions & Answers] DemonSoul:
OK when you got something please post certainly me and half of this topic is curious about this
[Samsung Galaxy S9+ Questions & Answers] jazzzzzzz:
I have given my device in service center to certify the issue,any one got money back ? Am planning to get money back if issue still persists after replacing
[Samsung Galaxy S9+ Questions & Answers] mikapharm:
Can't connect to samsung update server

Any help ?!
[Samsung Galaxy S9+ Questions & Answers] BlackBird_666:
I just check my device and I am getting the same error message! :eek:
[Samsung Galaxy S9+ Questions & Answers] BlackBird_666:
Just got off the phone with Samsung in Kuwait, they used samsung tutor to mirror my device and check for the black crush. The Samsung Tech assisting me could clearly see the black crush on his screen. He advised me to visit the samsung store to sort this out.

After visiting Samsung Store I will post an update.
[Samsung Galaxy S9+ Questions & Answers] andy7a:
Try booting Safe-Mode

Do you guys have this issues even in safe-mode? I have tried today booting in safe-mode and seems that the black crush is gone. I will try more when I get home into a darker environment.
[Samsung Galaxy S9+ Questions & Answers] Sanduro:
Tried it in safe mode and saw no change in black crush.
[Samsung Galaxy S9+ Questions & Answers] andy7a:
You are right , I got home now and the crush is still there. Going to return my phone and get a new one. Wish me luck with a better unit.
[Samsung Galaxy S9+ Questions & Answers] Sanduro:
Started to consider doing the same before my screen protector gets here, but from what I've heard most people that have returned theirs for new devices still have the same problem :\
[Samsung Galaxy S9+ Questions & Answers] Dojoman:
Have arranged mine to be returned. The black crush has ruined the whole experience for me. Shame as I love everything else about the device.
[Samsung Galaxy S9+ Questions & Answers] Chris_c81:
It's frustrating there hasnt been anything publicly from Samsung as it honestly is the one thing stopping the device from being awesome.
[Samsung Galaxy S9+ Questions & Answers] Toss3:
Yep. Considering selling mine and just waiting for the Note 9.
[Samsung Galaxy S9+ Questions & Answers] Avohkah Tamer:
Thanks for the reply. I looked through a few pages but didn't see it, so I figured I'd ask.

I went ahead and picked up an S9, and yeah, definitely doesn't have the problem.
[Samsung Galaxy S9+ Questions & Answers] garret1976:
All I know is that Samsung Netherlands has directed this issue to Samsung Korea, because development is in Korea they said.

But that's it. We have to wait I'm afraid. The more people complain at Samsung support, the sooner Samsung will recognize the problem.
[Samsung Galaxy S9+ Questions & Answers] DroidNvc:
Anyone from India finding the black crush problem on their device? My S9+ Exynos very much suffers from this. Tried watching a lot of content. The Infinity War trailer looks terrible. So do many other videos. Quite unfortunate.

Fiddled with the Screen Balance app but still hesitant to turn it on since true blacks are compromised.

Apart from this issue, the phone is a gem.

My device is already past the 14-day replacement window. Only repair option is available now.

Really confused..
[Samsung Galaxy S9+ Questions & Answers] BlackBird_666:
Alrightie, I visited samsung store here in Kuwait and spoke to one of their tech man. They have no clue what is black crush or how to resolve it. I had to explain it to him and even ask him to view the video in a dark room to see what I was talking about.

In the end they wanted to factory reset my S9 Plus, and if that did not resolve the issue, since device is over 14 days old they can only offer to replace the display!

I walked out and came back home to think about it!

Should I get the display replaced???
[Samsung Galaxy S9+ Questions & Answers] trenzterra:
True blacks is not compromised if you set screen balance sparingly.

---------- Post added at 05:38 PM ---------- Previous post was at 05:37 PM ----------

No one has conclusively proven that the issue has been solved. I think it's an inherent issue in all AMOLEDs, so no.
[Samsung Galaxy S9+ Questions & Answers] BlackBird_666:
Inherent issue in all AMOLEDs, I am so confused now! Then why do I not see it on my Brother's S8 Plus and my Father's Note 8 when playing the same videos that show black crush on my S9 Plus?
[Samsung Galaxy S9+ Questions & Answers] trenzterra:
I don't know, it's probably still there just that maybe it's less obvious. Or a placebo effect. My s7 edge suffers from it too if I look hard enough. And some claim their new units are "improved" then few hours later realise that the issue is still there.

AMOLEDs have other defects too anyway like screen tint unevenness, red screens etc. At the end of the day it's all luck of the draw.
[Samsung Galaxy S9+ Questions & Answers] DroidNvc:
The Screen Balance app as everyone knows is simply a band-aid fix for the actual issue. For me, it does compromise true blacks because of the degree of black crush in my device (which is horrible). Not really able to 'balance' the screen without some substantial tradeoff.

Sure, all AMOLED panels have this issue in varying degrees. But I have never seen or heard of any recent Samsung models (not just flagships) affected so badly by this issue. It remains a bummer until Samsung solves this problem.
[Samsung Galaxy S9+ Questions & Answers] BlackBird_666:
Just wanted to let you know, the other day I had no black crush after the XXU1ARCC UPDATE, I closed youtube and netflix app and reopened the apps and played the videos which shows black crush and :D there it was black crush.
[Samsung Galaxy S9+ Questions & Answers] Sanduro:
This has nothing to do with a placebo effect... My 4 year old nexus 6's oled display looks better than my s9+, N6 oled panel wasn't even the latest and greatest at launch, and that shouldn't be the case what so ever. Not to mention such an issue never being a thing on any S/Note 8 or iphone X display. Even the regular S9 doesn't have the same problem. Amoled screen's aren't perfect and do vary somewhat in quality, but this is a far bigger issue than it should be and oddly specific to this model. At this price point this isn't acceptable imo.
[Samsung Galaxy S9+ Questions & Answers] BlackBird_666:
Agreed, when you pay top money for a premium device this is not acceptable.
[Samsung Galaxy S9+ Questions & Answers] DemonSoul:
Exactly my s6+ doesn't have any issue with blacks like this mobile has, if my next one has this issue im asking for money back and moving on to the next phone almost 1000 euros for a mobile with this ****
[Samsung Galaxy S9+ Questions & Answers] Flash701:
Although there are known "issues" with OLED panels, I disagree that this is one we need to accept. I didn't have this issue on my S7 and the S9 doesn't have this issue. Let's not forget that the iPhone X is using a Samsung panel and does not display these properties. Apple did a great job with it. To dismiss this as "it's just how it is" is accepting subpar calibration for a phone priced near $1000.

As demonstrated with the Screen Balance app, software can help aleviate this (at the very least), but whether Samsung will release a patch is another story.
[Samsung Galaxy S9+ Questions & Answers] room511:
Just an FYI.

The device I picked up on launch day had to be returned because of screen burn in from the AOD.

That device did not have this "black crush" problem.

But... The new device I received does.

So those wondering if trading in their devices will fix the "black crush" , it might not.
[Samsung Galaxy S9+ Questions & Answers] jazzzzzzz:
If this is an issue with all the s9 plus then this thread might be filled with all members ..! but I see only around 40 people..!! So I hope issue is only with a particular batch of phones
[Samsung Galaxy S9+ Questions & Answers] Galaxo60:
Probably because most people hasn't noticed it.

I can only see it in very dark room with low brightness, otherwise, the screen is amazing.

;)
[Samsung Galaxy S9+ Questions & Answers] jazzzzzzz:
Today evening am going to get my replacement phone..! I don't know what to do if the issue is still there, Is there any option for a refund from Samsungs side?
[Samsung Galaxy S9+ Questions & Answers] BlackBird_666:
I only noticed it after coming across this thread :eek:

---------- Post added at 08:07 AM ---------- Previous post was at 08:06 AM ----------

Let us know how does the replacement device do with the Black Crush.
[Samsung Galaxy S9+ Questions & Answers] Chris_c81:
This.

Its nonsense to suggest this is placebo effect or acceptable. It's neither. I don't know why a few here are pushing the "accept it" wagon so hard. It's not acceptable. This is a premium device with a premium price tag. Absolute rubbish that previous devices from Samsung or any other manufacturer has the same problems. They simply don't. I never had it on my S7 Edge, S6 Edge, S5 or on the wifes S9.
[Samsung Galaxy S9+ Questions & Answers] zathus:
I think I'm partially blind or blissfully ignorant but I haven't experienced any of these issues. Not to say they're not there, sounds like they're pretty much there on every phone but to say that I don't seem to notice it. Which I'm going to take as a positive because if I did it would probably drive me nuts. I haven't gone to crazy in trying to replicate most of the examples because quite frankly, if I'm not noticing it and it's not bothering me why would I go out of the way to try to discover something that will bother me?
[Samsung Galaxy S9+ Questions & Answers] 10feethigher:
OK
[Samsung Galaxy S9+ Questions & Answers] antonis29:
same problem in my unit i am from greece black panther trailer is unacceptable in my opinion all units suffer from the same issue however not all users have been able to pinpoint it fingers crossed that samsung acknowledges and patches that via a software update
[Samsung Galaxy S9+ Questions & Answers] DemonSoul:
The thing is, i'm not going out of my way to discover it.

I was simply on my bed at 4 in the morning wanting to chill watching videos on youtube/serie , i dont want my screen at 100% on my face brightness and i lower it to 30% or around it, and there you go, it's on you'r face the problem. I would digest it on a 300€ mobile, but this ain't a cheap/middle phone, it's a premium price almost 1000€ for an equipment do this, while my friends mid price mobiles don't have this issue.

Meanwhile im still waiting for my new mobile, almost 1 week without stock on my store (FNAC), i'm going to take if off the box there and test it, if it has the same issue i'm wanting my money back and changing to other mobile. I can't use the phone with this problem triggers me so hard paying so much for a mobile with this problem, my s6+ doesn't has this after 3 years. 3 year phone!!!!! Works perfect on this sense
[Samsung Galaxy S9+ Questions & Answers] jazzzzzzz:
Just see black panther or avengers latest trailer in a completely dark room with lowest brightness.!! Still if u cant find it then you are giving me hope that my replacement phone may not have this issue..?
[Samsung Galaxy S9+ Questions & Answers] Lenkbron:
I'm a member of a German Android Forum and one guy from there just received his fifth S9+ because of different reasons, but he said all 5 had this issue.

So I do not really believe anymore that there are units out there which do not suffer from it.
[Samsung Galaxy S9+ Questions & Answers] Galaxo60:
I guess you need to speak with your store directly, because some stores have 14 days period and some others more.

;)

It's true all what you said, that for the "best screen in the market ever" (DisplayMate) we are having a lot of issues when brightness is below 50%, but you know what?, I'm sure Samsung is well aware of the issue, but they don't plan to solve it. I mean, just look all the marketing behind the screen: they were bragging a lot about the screen, the perfect color accuracy and the improved brightness, but is only because they probably know this new screen sucks in low brightness conditions. I can't believe that Samsung after many generations of really good screens, suddenly they come with a problem like this and they don't have any idea.

Even options like "Video Optimizer", which many times I enter to YouTube or video applications it asks me to enable it, and it only increases the brightness so this issue can't be spotted that easily.

And now comes the "fix", which is making nicer and better wallpapers, so people won't notice this problem at least with the stock wallpapers.

It's true that sucks, but it is what it is, and honestly, I think that is time for us to put in a balance if we want to keep a device with this problem or not, because Samsung doesn't even want to acknowledge the problem "officially" and they just put a smokescreen with stupid fixes.

If you can't live with the problem, is time to get a refund if you still can, because I'm sure newer devices will suffer from this also.

:rolleyes:
