4 Select On or Off for any of the following:
Geotag Photos: Available only when Auto Locate is selected. When
Geotag Photos is on, photos are tagged with the latitude and longitude
of the location in which they were taken.
Background Data Collection: Available only when Google Services is
on (see Turn location service providers on/off). When Background Data
Collection is on, anonymous location data is collected from your
phone. This data is used to improve the quality of location services.
Turn location service providers on/off
Location Services provides access to two location service providers—GPS
and Google Services. At least one of these must be turned on for Location
Services to be enabled. Both of them can be turned on at the same time.
1 Open Location Services .
2 To turn GPS on/off, open the application menu, tap Locate Me Using,
and tap GPS.
GPS, which is turned on by default, is a radio technology that uses
line-of-sight communication with satellites orbiting the earth. GPS is
very accurate for turn-by-turn directions and for pinpointing your
location when you are outside and have a clear view of the sky.
3 To turn Google Services on/off, open the application menu, tap Locate
Me Using, and tap Google Services.
Google Services uses cellular radio towers and Wi-Fi access points to
approximate your location. This technology is very fast to acquire a
location fix, but it is not as accurate as GPS. Certain applications, such
as turn-by-turn navigation solutions, require GPS to be activated in
order to work properly.
The first time you turn on Google Services you may be asked to review
and accept the terms of use, and decide whether to allow anonymous
data collection. Do the following:
• Review the terms of use.
• If you decide not to allow anonymous data collection, tap the
checkmark to remove it.
• Ta p Agree or Don’t Agree.
Google Maps
Google Maps will not be able to determine your location, and therefore will
not work properly, unless a location service is turned on (see Tu r n loc a tio n
service providers on/off).
1 Open Google Maps .
DID YOU KNOW? The geotag data is stored as an Exif tag in the photo file, not
on the image itself. A common use of the geotag data is in online photo services
like Photobucket and desktop apps like Google Earth, which use the data to
position the photo as a thumbnail on a map.
