You can let your phone use GPS, Wi-Fi networks, and mobile networks to estimate your location. Apps that have your permission can use this information to deliver location-based services, such as the ability to check in, view commute traffic, find nearby restaurants, or tag your photos with the location where you took them.

To control what location information your phone can use:

1. Drag the status bar down with two fingers and touch  Settings.
2. Touch Location access.
3. Use the ON/OFF toggle to give or remove permission to use your location information. When the switch is off, your phone can't find your precise location or share it with any apps. However, turning this off disables many useful features and apps.
