iPhone UX challenge

I've attempted David Hammill's UX challenge to redesign the iPhone screen for accepting or declining a call while you are already on another one.

Threads message
Incoming call while on another

These feelings are very relatable. As an iPhone user, when I get a second incoming call, I panic and freeze. Eventually, the caller gives up, and the problem resolves itself.

Separate contexts

When a new person calls, the iPhone prioritizes that call and asks the user to make a decision while they are in the middle of another task. It’s overwhelming for the user.

Here I am, talking to Jim Carrey, and suddenly I see "Margot Robbie" in big letters on my screen. What happened to Jim? Is he still there?

Everything incoming, while the user is in the middle of a task (calls, messages, Taylor Swift ticket sale notification) is just that — a notification.

The main changes:

This is my proposed solution. Would be very interesting to test it.
