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.
