It works just the same as iOS, where the first time an app wants to use your location/etc it asks android, which shows a prompt:

And can be revoked as well:

Once you grant e.g. permission to access the microphone to an Android app, it can do so at any time without you noticing. Until you manually go to the settings and revoke the permission, that is.
If you change the permission to ‘always’ the banner won’t show.
Mic recording, on the other hand, is always user-initiated and very explicit.
With the pace of Android adoption, the new permission model isn't even present on half the devices that have been tracked on the Android Dashboard. [1] Versions 6 and 7 combined are at 48% adoption as of this moment, according to this dashboard.
On the iOS side, the granular permissions model has been around since the last seven years or longer, IIRC. And iOS devices have a much higher rate of new OS adoption, which means almost every iOS device currently in use has the same permission model for a lot longer.
