GPS & AGPS
Certain Samsung Mobile Devices can use a Global Positioning
System (GPS) signal for location-based applications. Changes
may affect the performance of location-based technology on your
mobile device.
Certain Samsung Mobile Devices can also use an Assisted Global
Positioning System (AGPS), which obtains information from
the cellular network to improve GPS performance. Contact your
wireless service provider for details.

Use of AGPS in emergency calls

When you make an emergency call, the cellular network may
activate AGPS technology in your mobile device to tell the
emergency responders your approximate location.
AGPS has limitations and might not work in your area.
