near a powerful radio or television tower

  when your AGPS antenna is covered (for example, by 

your hand or other object) or facing the ground

  when there are temperature extremes outside the 

operating limits of the phone

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. Walking or 

driving very slowly may also substantially reduce AGPS 

performance.

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.
