Updating Satellite Almanac Data
• 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.
• Hold your phone to enhance reception. Signals
from GPS satellites are transmitted to your GPS
antenna, which is inside the back of your phone,
opposite the earpiece, above the label with your
service provider’s name on it. 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.
• 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.
• 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, the GPS antenna
has best access to GPS signals in a car when
placed near a window.
Note: Although moving your phone at a walking
pace decreases GPS performance, moving
it at the speed of a moving car does not.
• Stay in network coverage. Depending on who
your service provider is, the network will provide
your phone with information that helps determine
your location more quickly and accurately.
