If you want a sample of how good a landscape can be when shot with a mobile phone, check out this guy on Flickr:

He seems to shoot primarily in the Southwest (of the US) with a variety of iPhones from a 5s to an X.
EDIT: Or instagram https://www.instagram.com/allophile_/ although at first glance there look to be more landscapes in the Flickr feed.
