I work on iOS/Android games, this is probably innocent. It's frustrating to us that the permissions to know whether you are receiving a phone call is part of these permissions. We use it just to pause the game when a phone call comes in, nothing more, but get a lot of people complaining that we don't need access to their contacts (the same people who deny them and then complain that the game doesn't pause when they get a call).
Since the hardware manufacturers started being much more up-front about permissions to the users, they need to match that by naming them/describing them properly to avoid this.
