I've started getting these notifications on my Android device.
Each app that makes a location request in the background causes a notification that allows me to take away location access from the app, only allow location access when the app is in the foreground, or always allow location access.
You get a notification when the application accesses your location from the background.
You're not using the app at the time it makes the request, and you get a system notification telling you about the location access.
I haven't seen a map on Android though. I like that.
