People keep saying it’s so an app can resize to the full interior screen but none of the marketing photos actually have this. So its hard to say “what a genius masterstroke by Apple.”
Most have the closed screen plus another view. Or the lock screen which is a full photo open and a small section closed.
Im not saying its not possible but it doesn’t seem like that is their intention.
A lot of people will look at this and say. Eh I already have an Ipad and a Imac why do I need a phone with such a large screen.
Their selling point is: Not having to switch from one app to another when Multitasking.
