Logo image not showing large on Mobile

I think this is a big issue with new people like myself.

Can I please get some help to make this logo larger on mobile?
I created a double-size logo in photoshop, placed the PNG in the retina logo box (in BE Options), made it “Full size” in that settings box.
But I cannot get the logo to be sized correctly in mobile. (Turn phone sideways makes it larger, but that’s not what they’re looking for :/
I’m really confused, or getting there.
Thank you!
