I got a brand new (i.e. sealed) iPhone 7 Plus without simlock. When I turned it on it asked me for my Wifi password, activated itself, asked me to login to my iCloud account and configured itself as a new iPhone.
The Apps & Data screen, where I can choose to restore a backup as never shown. As it came with iOS 10 preinstalled I assumed I had to upgrade the device in order to use this functionality. Nope. Even with iOS 11, whenever I configure it (i.e. after choosing "Erase all content and settings") it won't display that particular screen.
Any idea what the reason might be? I'm coming from an iPhone 5c and made an iCloud backup which I want to restore on the new iPhone 7 Plus.
