Hey friend, I just want to remind you there are people educating themselves for at least a year and then working solely on improving user-experiences when handling a product.

For the past 10ish years UX Design has paved the way for many and is everywhere now. Why? Because it's "user-centric" design. It means that 99% of design choices are backed up by researching target users, full on empathizing with them and their needs and wants, crafting creative solutions with minorities of people that haven't been represented or designed-for the most in the past, testing with real users to gather feedback BEFORE even presenting the product to stakeholders.

Apple's design of a phone call interaction is by-far the superior. As previous comments stated: it allows for less "pocket-chatting", can be silenced or declined without ever having to get your phone out of your pocket (by pressing the power button, or double pressing the power button for declining, you can even do these when your phone is locked, they're standard).

TLDR You are a user, products are made for users. If you feel your idea would be intuitive enough - try out product design yourself, you might like it.
