The compass has limited accuracy. Electromagnetic fields, metal objects, or other
external circumstances may also affect the accuracy of the compass. The compass should
always be properly calibrated.

About positioning methods

Maps displays your location on the map using GPS, A-GPS, SA-GPS, WLAN, or network
(cell ID) based 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 and accuracy of the positioning. Self-assisted GPS (SA-GPS)
provides the fastest positioning without using a network connection.
WLAN positioning improves position accuracy when GPS signals are not available,
especially when you are indoors or between tall buildings.
With network (cell ID) based positioning, the position is determined through the
antenna system your phone is currently connected to.
To save on data costs, you can deactivate A-GPS, WLAN, and network (cell ID) based
positioning in your phone positioning settings, but calculating your location may take
much longer.
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
