Not pretty when compared to my old Nexus 5. :(

The top picture is the S9+. The photo I've taken can't capture the artefacting in those scenes during motion. For example, the black areas seem to be moving around like liquid.

I'll try another photo later. Unless like a member said, my problem is not black crush but something else completely.

The black parts moving around like liquid is sadly just a common issue with oleds.

On those look quite good.

Maybe Display Tester app is the problem.

It's not. One in the S9/S9+ Telegram group brought his S9+ in, and after the seller compared it to his own S9, which didn't suffer from the same issue, he's now possibly getting a new one.

This sucks, it is the first time i get an Amoled screen with a perfect uniform white balance, and then this black crush thing happens, damn it.

I hate going through replacements as they might be worse, so its either i wait for a fix which is going to take a while, thats even considering its going to happen in the first place, or go for another phone, and at the moment there is no phone that seems worth it tbh.

Another try to demonstrate the problem.

Top image is S9+ bottom S8. Apart from the fact that the S8 image is much more natural with colour reproduction, notice the significant loss of detail on the hand and fingers in the S9+ display. The entire thing is covered with a greyish smudge.

I don't know if this is the black crush other members refer to but there is definitely a problem with my unit and how shadows are displayed in general.

I don't mind sharing the photo attached, feel free to use it.
However since it's a photo and not a screenshot, I'm not sure if it's going to be of any help. Unfortunately Google Play movies doesn't allow screenshots due to security policies.

Ok, I thought it was your own photo.

I see the issue in display tester but I have not noticed anything wrong while watching videos or photos.

OK. For users that want to try a direct like for like comparison with their devices, I attach a screenshot image and two photos showing how it's displayed between the two devices.

So, top image is the original screenshot, middle photo is S9+ screen and bottom is S8.

As for what to look for, pay close attention to the eggs in the photos and notice how they loose most colour detail on the S9+ screen compared to S8. I think it's pretty apparent.



Obviously if the image looks more like the bottom photo on your displays, you don't have the issue.

Photos normally make the image appear brighter than what actually is.

The test is done by cranking up a bit the brightness of your display and focus on the egg details. If they don't appear smudged, your display doesn't have this particular issue.

That's totally my issue. It's as if there isn't enough colour depth or something. There's gradient banding everywhere and crush all over the place. White balance is excellent for the first time, but everything else is just off.
