Question Galaxy J6 (SM-J600G/DS) ink like substance inside screen

[iam480p]

Good day. I have a Galaxy J6 running android 10 (ota update) and my screen is having this issue where it seems like the inside of the LCD has some sort of substances making the phone unusable for daily use. I vape in my room with pretty good ventilation. I wonder if it's related to this issue or if it's software related.

Unless your vaping too much chronic, bad LCD screen. Replace.
