Android phones from major manufacturers, and Apple phones: doubt it.

Bold added for emphasis, Apple claims privacy as a feature and OS control of the mic to prevent this exact sort of thing. Not only would someone have found it, it would be a news cycle on the mainstream news, and basically just the wallpaper for any tech-centric website.

I mean, fucks sake, iFixIt alone would find mics in places they shouldn’t be and this would be a story.

Unfortunately, the truth is more boring, and basically pretty much every app/website most of us use are tracking us in some way unless you really seek prevention. They don’t need the mic.
