Even where location information can be calculated in such
situations, it may take more time than usual, and your
location estimate may not be as accurate.
Even where adequate signals from multiple satellites are
available, your AGPS feature will provide only an
approximate location, often within 150 feet (45 meters) but
sometimes much farther from your actual location.
The satellites used by your phone's AGPS feature are
controlled by the U.S. government and are subject to
changes implemented in accordance with the Department
of Defense AGPS user policy and the Federal Radio
Navigation Plan. These changes may affect the
performance of your phone's AGPS feature.
Conserving Battery Power
Your phone includes an ambient light sensor and
battery save setting to extend battery life. When this
feature is activated, it automatically turns off the keypad
backlight when it detects that enough ambient light is
available. Inhibiting or covering the sensor can cause
intermittent backlighting.
