Positioning and location services

About positioning methods
Your phone displays your location using GPS, A-GPS, Wi-Fi, or cellular positioning.
The Global Positioning System (GPS) is a satellite-based navigation system used for
calculating your location. Assisted GPS (A-GPS) is a network service that sends you
GPS data, improving the speed of the positioning.
Wi-Fi positioning improves position accuracy when GPS signals are not available,
especially when you are indoors or between tall buildings.
With cellular positioning, the position is determined through the cellular network
antenna your phone is currently connected to.
To save on data costs, you can switch A-GPS off in your phone positioning settings,
but calculating your location may take much longer.
You can also switch Wi-Fi and cellular positioning off in your phone settings.
Depending on the available positioning methods, the accuracy of positioning may
vary from a few metres to several kilometres.
