GPS Enabled
Your Smartphone’s GPS Enabled feature uses information from Global Positioning
System (GPS) satellites orbiting the Earth to determine the approximate geographical
location of your Smartphone, expressed as latitude and longitude. The availability and
accuracy of this location information (and the amount of time that it takes to calculate it)
will vary depending on the environment in which you are using the GPS feature. For
example, GPS location fixes are often difficult to obtain indoors, in covered locations,
between high buildings, or in other situations where you have not established a clear
broad view of the sky. Also, nearby radio and electronic equipment may block or interfere
with reception from these distant satellites. SEE: “IMPORTANT: Things to Keep in
Mind”.
When you make a 911 emergency call, the GPS feature of your Smartphone can help
emergency personnel locate you if your Smartphone has adequate access to GPS
satellite signals and your emergency response center is equipped to process such
information.
You can also use the GPS feature to view your approximate location. Location
information appears on the Smartphone’s display.
Java applications loaded on your Smartphone can also request your location. If your
Smartphone is connected to a laptop computer or similar device, software running on
that device can request your location. To protect your privacy, you can control whether
these requests are granted.
IMPORTANT: Things to Keep in Mind
If you are using the GPS feature of your Smartphone while driving, please give full
attention to driving and to the road.
Where adequate signals from multiple satellites are not available (usually because
your GPS antenna cannot establish a view of a wide area of open sky), the GPS feature
of your Smartphone WILL NOT WORK. Such situations include but are not limited
to:
• In underground locations
• Inside of buildings, trains, or other covered vehicles
• Under any other metal or concrete roof or structure
• Between tall buildings or under dense tree-cover
• Near a powerful radio or television tower
• When your GPS antenna is covered (for example, by your hand or other object)
or facing the ground
• Some radios, entertainment equipment and other electronic devices may
generate signals that can block or interfere with the GPS receiver ability to
receive the distant satellite signals, particularly when such devices are
operating in close proximity to the GPS receiver. Therefore, in a 911 call, or
when otherwise using the GPS location function, always move your phone away
from any such devices.
• In temperature extremes outside the operating limits of your Smartphone
Walking or driving very slowly may also substantially reduce GPS performance.
