Recent Android devices contain displays with notches. Chrome does not support such displays. (For example, it is not possible to create web content with a background image that fills the entire display, but with text that is guaranteed to avoid the notches.)

Android P will fully support cutouts (potentially even multiple cutouts?), so it would be good to have Chrome support this when it's released.
