For a company that prizes itself on its privacy credentials, Apple received a bit of a bloody nose earlier this week when long-time security journalist Brian Krebs revealed the iPhone 11 Pro intermittently seeks the user’s location — even when there are no applications with location permissions in use.

In recent years, Apple has heavily marketed the iPhone as a more secure and private alternative to Google's Android operating system. The fact that Cupertino's latest mobile periodically pings cell towers and GPS satellites to figure out where the user is, regardless of their settings, is obviously at odds with that messaging.
