Enhancing GPS Performance
Sometimes the GPS feature of your phone may be unable to
complete a location calculation successfully. If this happens
when you are making an emergency call, the location of the
nearest cell tower in contact with your phone is made
available to the appropriate emergency response center if the
center has the capability to receive such information. If this
happens when you are trying to view your location on the
phone’s display, you will see a message indicating that your
phone cannot access satellites.
To improve accuracy and increase your chances of a
successful calculation, do the following while your phone is
determining your approximate location:
䢇
Stay in the open. The GPS feature works best where there
is nothing between your phone and a large amount of
open sky. If possible, go outside, away from tall buildings
and foliage. While performance in a building is improved
by moving closer to windows, glass with certain sun
shielding films may block satellite signals.
䢇
Hold your phone to enhance reception. Signals from GPS
satellites are transmitted to your GPS antenna, which is in
your phone antenna. Hold your phone away from your
body, giving the antenna clear access to satellite signals.
Do not cover the antenna area with your fingers or
anything else.
䢇
Stand still. If possible, stand still until your phone is
finished determining your location. Moving your phone at
a walking pace while your phone is calculating your
approximate location may substantially decrease GPS
performance.
䢇
In a car. When using the GPS Enabled feature in a car,
position your phone so that the GPS antenna has good
access to GPS signals through the car’s windows. Typically,
