sGPS & your location

the network where you are physically located.

sGPS limitations & tips
Your phone uses simultaneous Global
Positioning System (sGPS) satellite signals to
estimate your location. If your phone cannot find strong
satellite signals, your sGPS might be slower, less
accurate, or it might not work at all. sGPS provides only
an approximate location, often within 150 feet
(45 meters) but sometimes much farther from your
actual location.
To improve sGPS accuracy:
• Go outside and away from underground
locations, covered vehicles, structures with
metal or concrete roofs, tall buildings, and
foliage. Indoor performance might improve if
you move closer to windows, but some
window sun shielding films can block satellite
signals.
