S9 Plus Serious Black Crush Issue

[Sarthak Patel]

Anyone else having the serious BLACK CRUSH issue on the S9 plus. It is way too prominent in dimly lit environments, thought not noticeable in well lit places. Videos look almost garbage when in a dark place. The blacks in the video are way off, looks like green/black blocks. I first noticed it while watching Shawn Mendes's In My Blood music video and then noticed it in the infinity wallpapers(highly prominent at the corners). Can we expect a update soon or I should return my handset?

I don't have an S9/S9+ so I can't directly comment on its particular screen from experience, but I do have a Note 8, Note 7, S7E, and a Note 5 and none of them exhibit this behavior that you are talking about.  In fact, the only display I have seen that is (very slightly) better looking to me personally is that of the iPhone X.  In fact, I directly compared the X to the Note 8 for weeks at various stores with different examples, agonizing over them for every little detail to even come to that conclusion, and at the end of the day the Note 8 was still easily better looking than any other phone I saw.  Given that the S9+ has virtually the same display as the Note 8, I am curious as to what is going on with yours?

 

In fact I actually have a hard time understanding how an AMOLED display can even show black crush due to the way it works?  I mean, with AMOLED a pure black is just the pixels being turned completely off.  Therefore, anything lighter than pure black should have the pixels emitting at least a very small amount of light and thus not absolute black, right?

It is highly noticeable in dark places and almost non existent in well lit environments as I mentioned. I researched on other forums and found that many other users too are having the same issue. I also came to know that Pixel 2 had this issue too.

 

Is this BlackCrush problem arising because I am watching 1080p Youtube Videos on a 1440p panel?

Black is almost never perfectly black. Sounds like OP just got a dead display.

Try watching this video on your S9 plus in a dark room. And notice the blacks in the video. Especially the black backdrop at around 03:55. Is it just me or anyone else having the same issue?

With the way OLED functions, a fully black screenshot should appear as perfectly black as is possible because the entire screen will basically be emitting no light at all.  Can't imagine a way that a display could possibly ever be any blacker than being turned off?  Its not like you can emit negative light.
