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

Literally a week after my warranty ended. Samsung wasn't helpful at all in fixing the problem, however very eager to recommend a new smartphone..

This needs something like a class action lawsuit. Samsung has obviously sold a bunch of lemons.

bro the same happened with mine and still is. i searched everywhere but couldnt find a direct solution. the only thing which works for me is when i turn on the Always on display and when the screen is faded, i lock the screen and wait for the AOD to get activated and once activated i directly unlock my phone through finger scanner and the display gets fine..  if i unlock it immediately after locking it when the AOD is not activated then the problem is still there.
