Well known security expert, KrebsOnSecurity, recently discovered a privacy issue with iPhone 11 Pro. The researcher found that Apple’s latest phone will still continue to collect location data even if you’ve changed the individual settings to disable location data.
According to Apple’s own privacy policy “You can also disable location-based system services by tapping on System Services and turning off each location-based system service.” However, there are services on the iPhone 11 Pro that request location data and don’t have an option to individually disable them. In order to disable data collection from these services you’ll have to turn off location services entirely (which will ultimately prevent you from using many popular apps such as Maps).
An engineer at Apple responded to the discovery by saying “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.”
However, this obviously conflicts with Apple’s device having individual controls allowing you to turn off location services on a granular level.
