Think more on what the app does. It allows you to make calls. It needs access to the microphone.

But a user likely doesn't want to be forced to keep WhatsApp open as the front screen app while in a call. Maybe they want to open their e-mail or Calendar while in a call. That means the app needs to be able to use the microphone while running in the background.

Though I suppose you could argue that the app should not be allowed to start using the microphone while the app is in the background. Yes, I think that'd be quite reasonable.

That’s the crux of the problem. Why should any app be able to start a listening session without the user’s explicit intervention?

Voice control. I can set-up Alexa on my phone to listen for the Alexa keyword.

Not that I have that enabled, but it is an option.

And a well designed OS would think about the security implications and it would orchestrate, “when a certain word is heard, launch $x”

What if you want to answer a call straight from the notification dropdown?

You can do that on iOS devices after you explicitly press a button to answer the call
