Hi, I have been using my s9+ for a year and so far I haven't had any problems. Last night, the display started glitching - and since then has been very grainy with a faded tone, like the colours are faded. And under low brightness, the darker parts of my phone are not visible and it glitches as well. Googling showed me that the term is black crush but I'm not sure, and that it is a software issue. It would be really nice if someone could help me out and tell me how to fix it - is there something I can do? I've attached photos of the black glitching. I dont have clear photos of the grainy screen though.
