When it comes to iOS, much of the focus right now is iOS 13.
It's important to note that the new feature is limited to newer iPhones, with only the iPhone XS, XS Max, XR, and iPad Pro eligible to use the new technology.
According to Apple, the periodic pop-up alerts for location tracked by apps will give users an option to either give background location tracking access to an app, or revoke it completely, or modify it to "Just Once"/ "only while using" the app.
The screenshot below shows the locations used by the Tesla app and the App Store. In this notification, we will see a part of the map and its location data where the specific application has tracked.
Besides alerting users that a particular app is tracking them while running in the background, the popup also gives a developer the opportunity to try to convince users that they have a legitimate reason for tracking them.
The notification also asks whether users want the tracking to continue and the options are "Change to Only While Using", and "Always Allow".
iOS 13 will be out on all compatible devices (iPhone 6S and SE onward) in Fall 2019. The new location notification with a map is meant to sensitize users on location permissions.
As AppleInsider reports, the new technology relies on crowdsourcing from Apple's massive user install base, sending out Bluetooth beacon signals that are picked up by nearby iOS or Mac devices, which then pass on a found device's identifier and their own location information back to Apple for later access by Find My users.
