iPhone XS Strange Dark Blob on iPhone XS password screen

[Vorning]

I’ve recently noticed this black spot when entering my password.
It’s only when I enter my password. What do I do?

What black spot?

It is just the screen background.

There is nothing wrong with you phone, OP. It is how Apple intended. It is a blurred background on purpose.
