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, including data
relating to your current location, 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.
