Many cell phones today have dedicated sensors that can determine your
location using GPS satellites. These sensors provide support for some
very useful applications, such as turn-by-turn navigation. There are
some reasons why you may wish to disable this support, and it is easy to
do so. Disabling the GPS when you are not using it can improve the
battery life of your phone. Your phone's camera also uses the GPS to
encode the location of each photo that you take with it, and you may
wish to disable this to protect your privacy.

The Main Steps
Press the menu or
enter key on your cell phone to enter the main menu. Some touchscreen
phones allow you to simply press a menu icon on the screen to enter the
phone's main menu.
Look for an entry in
the menu labeled "Location," "Options" or "Settings." The GPS
location-sharing option could be listed under a different menu heading
depending on the manufacturer of the phone. Some phones contain a
listing under "Options" or "Settings" called "E911" that will allow you
to disable the tracking feature.
Use your
phone's arrow keys or touchscreen to highlight the option to disable
the location or GPS system. Press the "Enter" or "OK" key to select the
option to disable the location-tracking system. Some cell phones provide
only an "On" and "E911" option instead of an option to disable tracking
completely. If you select "E911," only a 911 call center operator will
be able to see your location if you call from your cell phone to report
an emergency.
What is E911?
E911 (Enhanced 911) is a system adopted by the U.S. FCC (Federal
Communications Commission) that tracks the number of the mobile within
100 meters. The government requires all wireless service providers to
include such features to instantly identify and locate callers during
emergency situations.
Enhanced 911, E-911 or E911 is a system used in North America that links emergency callers with the appropriate public resources. Three-digit emergency telephone numbers originated in the United Kingdom in 1937 and have spread to continents and countries around the globe. Other easy dial codes, including the 112 number adopted by the European Union in 1991, have been deployed to provide free-of-charge emergency calls.
In North America, where 9-1-1 was chosen as the easy access code, the
system tries to automatically associate a location with the origin of
the call. This location may be a physical address or other geographic
reference information such as X/Y map coordinates. The caller's
telephone number is used in numerous manners to track a location that
can be used to dispatch police, fire, emergency medical and other
response resources. Automatic location of the emergency makes it faster
to locate the required resources during fires, break-ins, kidnappings, and other events where communicating one's location is difficult or impossible.
In North America the incoming 9-1-1 call is normally answered at the Public Safety Answering Point (PSAP) of the governmental agency that has jurisdiction over the caller's location (see #Location below). When the 9-1-1 call arrives at the appropriate PSAP, it is answered by a specially trained official known as a Telecommunicator.
In some jurisdictions the Telecommunicator is also the dispatcher of
public safety response resources. When a landline call arrives at the
PSAP, special computer software uses the telephone number to retrieve
and display the location of the caller in near real-time upon arrival of
the call.
