S9 suddenly washed out colors, black crush

[xtexistenz]

Hi, I've bought this phone in 2018 with a pre-order before it even came out, I was really happy with this phone until now (I still think it's one of the best looking phones right now, no stupid punch hole, just a perfect design). It seems that there may be a problem with the display, the colors suddenly changed a bit right when I was using the phone, they were washed out and the display is somewhat brighter now at the same brightness setting, it looks like there's less contrast and the greys look very bad right now, they look a bit greenish and as I mentioned, brighter.

There also seems to be a problem with black crush now when the screen is at like 30% brightness or lower, it looks kind of pixelated and the gradients look very bad (gradient banding). I really loved this phone for the beautiful display but right now everything looks pretty bad.

I've never dropped the phone or anything like that, just used it normally. I don't believe that OLED screens only last for 2 years and I've always used it on low brightness (I don't even understand why a lot of people keep their phones at full or almost full brightness).

I'm actually not sure if this is a hardware problem or a software problem? It seems to be hardware because I didn't change anything software wise.

Is this a known problem and is there anything I can do to fix it or is the display toasted?

Thanks

I'm having exactly the same issue with my Galaxy S9 (SM-G960F) since a few weeks ago and can't find any solution. I think I didn't install any software updates lately. My phone is running Android 10 with the latest security patch from March 1st 2022. Have anyone tried installing custom ROM and checking if the issue is still present? All I've tried just yet is only wiping system cache in the bootloader and hard-resetting the phone. I will update you if I find a solution or at least something interesting.

This happened to me too, I noticed it this morning, if they don't fix this for free, there will be hell to pay and you guys are with me!

The same thing just happened to me, this has happened to my girlfriend's S9 before, but I thought it would be because she dropped it on the floor once, but I never dropped mine. The worst thing is that I came here to see that this has been happening with several S9s for at least two years and Samsung has not taken any action. It could have recalled or at least released an update to fix it, after all two years is a long time for that. Now that my S9 is on the way to becoming a paperweight and Samsung feels it's right to play this trick on consumers it's time to switch brands.
