Window camera is way too small !!!

Unfortunatly, the window camera is too small. It is very hard too see the scene we are taking a picture of...a bigger window and a smaller wheel would be great. I know we have full screen view in manual mode, but Im talking about auto mode. So small a camera window with iphone 6s is really weird...come on guys ! Redesign the app. !
