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.

The availability and quality of GPS signals may be affected by your location, satellite

positions, buildings, natural obstacles, weather conditions, and adjustments to GPS

satellites made by the United States government. GPS signals may not be available

inside buildings or underground.
