About positioning methods
Your phone displays your location using GPS, A-GPS, WLAN, 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. In addition, other enhancements
to GPS may be used to improve and speed up the positioning. These may require
transferring small amounts of data over the cellular network.
Wireless local area network (WLAN) 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 deactivate A-GPS in your phone positioning settings,
but calculating your location may take much longer.
You can deactivate WLAN in your phone internet connection 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.
Do not use GPS for precise location measurement, and never rely solely on the
location information provided by GPS and cellular networks.
Coordinate information may not be available in all regions.
Deactivate assisted GPS (A-GPS)
Assisted GPS (A-GPS) helps your phone determine your current location more quickly.
A-GPS is a network service. To save on data costs, especially when abroad, you can
deactivate the service.
