DID YOU KNOW? The geotag data is stored as an Exif tag in the photo file. 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.

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 smartphone. 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.

1Open Location Services .

2To 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.

3To 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.

•Tap Agree or Don’t Agree.

Google Maps

Google Maps cannot determine your location and therefore cannot work properly unless a location service is turned on (see Turn location service providers on/off).
