Faint black line on left notch
i would like to know is it a common issue for Iphone 11 to have a faint black vertical line on left notch of the screen? I went to service provider and it said it will be okay once i have update my IOS however the line is still there though i have updated my IOS and the line seems to be more noticeable and it keep getting wider.
You can see it is showing in the photo below it is more clear when you see it on the screen itself.
What should I do?
