New Call UI
This may seem like a small thing, but another “finally!” change that’s coming to the iPhone and iPad is a significant improvement to incoming call notifications. Instead of taking over the entire screen when incoming calls arrive — which Craig Federighi acknowledged is “not cool” — incoming calls will now show up as a notification banner at the top of the screen, just like any other notification.
You can then tap to answer or flick away the notification to dismiss the call, with no interruption or distraction to what you’re currently working on. This will also work with every app that uses the CallKit UI, so whether it’s traditional cellular phone calls, FaceTime calls, or Skype calls, they’ll all use the new compact banner notifications.
