How do I know the screen resolution of my smartphone?

[Kross]

I have been hearing how the screen resolution of a smartphone affects the picture quality of the smartphone. But for some of us, we don't know how to check the screen resolution of our smartphones.

From which menu can one check the screen resolution of a smartphone?

I think if one goes to the display settings of the phone, they would be able to see the screen resolution of their smartphones.
