Positioning and location services

About positioning methods
Your phone shows your location on the map using GPS, A-GPS, Wi-Fi, or cellular
positioning.
GPS
A-GPS
Wi-Fi
Cell ID
A-GPS and other enhancements to GPS may require transferring small amounts of data
over the cellular network. If you want to avoid data costs, for example when travelling,
you can switch the mobile data connection off in your phone settings.
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.
The GPS of this device is not for professional positioning. GPS connection time might
also be affected by weather, use environment, and other condition of use. GPS should
only be used as a navigation aid and should not be used for emergency or task which
requires more precise positioning.
The global positioning system (GPS) is a navigation system that
uses satellites to work out where you are.
The Assisted GPS (A-GPS) network service retrieves location
information using the cellular network, and assists GPS in
calculating your current location.
Wi-Fi positioning improves positioning accuracy when GPS signals
are not available, especially when you are indoors or between tall
buildings.
You can also switch Wi-Fi and cellular positioning off in your phone
settings.
With network (cell ID) based positioning, your phone locates you
through the cellular system your phone is currently connected to.
