My coworker just bought a new iPhone XS. His iPhone SE just died, so he needed a phone. If he had been updating his SE with the latest iOS, what's new for him now that he has the XS? In the past, I remember seeing articles that outlined the significant changes slow upgraders would see. Does anyone know of such an article? I tried googling it, couldn't find anything. Obviously, the home button change and the face recognition are big ones. I he's had iOS 12, then it's really just physical differences, right? Like a better camera.
