GPS & AGPS
Certain Samsung mobile devices can use a Global Positioning
System (GPS) signal for location-based applications. A GPS uses
satellites controlled by the U.S. Government that are subject to
changes implemented in accordance with the Department of
Defense policy and the 2008 Federal Radio navigation Plan (FRP).
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. AGPS uses your
wireless service provider's network and therefore airtime, data
charges, and/or additional charges may apply in accordance with
your service plan. Contact your wireless service provider for
details.
Your Location
Location-based information includes information that can be
used to determine the approximate location of a mobile device.
Mobile devices which are connected to a wireless network
transmit location-based information. Additionally, if you use
applications that require location-based information (e.g. driving
directions), such applications transmit location-based
information. The location-based information may be shared with
third-parties, including your wireless service provider,
applications providers, Samsung, and other third-parties
providing services.
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. Therefore:
• Always tell the emergency responder your location to the best of your
ability; and
• Remain on the mobile device for as long as the emergency responder
instructs you.
Navigation
Maps, directions, and other navigation data may contain
inaccurate or incomplete data, and circumstances can and do
change over time. In some areas, complete information may not
be available. Therefore, you should always visually confirm that
the navigational instructions are consistent with what you see
before following them. All users should pay attention to road
conditions, closures, traffic, and all other factors that may impact
safe driving or walking. Always obey posted road signs.
