Twenty Fifteen featured image size too big in mobile

I am having problems with the featured image on out website. It shows up fine on the front page both mobile and on desktop. When I view all the other pages they have a space at the bottom of the image and when you view that on mobile the space is really big. And for some reason on some Droid phones the featured image is really big and you have to zoom back in to view the site which is not what we want our visitors to have to do. But on iphones and other androids the site seems to look fine except for the big space below the featured image. Any help would be greatly appreciated.
