LCD Issues

Phone: Tecno Camon 40 Pro 5g

I experienced this issue with my previous phone before and mow its back on my main one?

So I have these purple dots, very small and faint but it can be seen if you're looking hard for it. So I know this might spread becauss it happened to my old phone(realme). But the problem is I already took precautionary steps to ensure I won't make the mistake again: Didn't drop it, didn't let it sleep near me since I roll a lot in my sleep, and it didn't even drop on water. Yet SOMEHOW despite it all, these purple dots appeared like wtf.

I'm hoping this is a factory defect because I promise you I took care of this phone since I pretty much bought it last June. And I'm hoping my warranty covers it cause no way I'll let this spread.
