Original Post from Krebs on Security
The policy explains users can disable all location services entirely with one swipe (by navigating to Settings > Privacy > Location Services, then switching “Location Services” to “off”). When one does this, the location services indicator — a small diagonal upward arrow to the left of the battery icon — no longer appears unless Location Services is re-enabled.
The policy continues: “You can also disable location-based system services by tapping on System Services and turning off each location-based system service.” But apparently there are some system services on this model (and possibly other iPhone 11 models) which request location data and cannot be disabled by users without completely turning off location services, as the arrow icon still appears periodically even after individually disabling all system services that use location.
On Nov. 13, KrebsOnSecurity contacted Apple to report this as a possible privacy bug in the new iPhone Pro and/or in iOS 13.x, sharing a video showing how the device still seeks the user’s location when each apps and system service is set to “never” request location information (but with the main Location Data service still turned on).
The video above was recorded on a brand new iPhone 11 Pro. The behavior appears to persist in the latest iPhone operating system (iOS 13.2.3) on iPhone 11 Pro devices. A review of Apple’s support forum indicates other users are experiencing the same issue. I was not able replicate this behavior on an older model iPhone 8 with the latest iOS.
This week Apple responded that the company does not see any concerns here and that the iPhone was performing as designed.
“We do not see any actual security implications,” an Apple engineer wrote in a response to KrebsOnSecurity. “It is expected behavior that the Location Services icon appears in the status bar when Location Services is enabled. The icon appears for system services that do not have a switch in Settings” [emphasis added].
Apple has not yet responded to follow-up questions, but it seems they are saying their phones have some system services that query your location regardless of whether one has disabled this setting individually for all apps and iOS system services.
Granted, the latest versions of iOS give users far more granular control over the sharing of this data than in the past, especially with respect to third-party apps. And perhaps this oddity is somehow related to adding support for super-fast new WiFi 6 routers, which may have involved the introduction of new hardware.
But it would be nice to know what has changed in the iPhone 11 and why, particularly given Apple’s recent commercials on how they respect user privacy choices — including location information. This post will be updated in the event Apple provides a more detailed response.
