Using location services
Location services allow applications such as Maps and the camera to use information from your mobile or Wi-Fi network as well as GPS (Global Positioning System) information to determine your approximate location.
In order to use your device to find out where you are, you need to enable location services.
For more information, go to support.google.com/.
Find and tap [Settings] > [Lock screen & security] > [Location].
Tap the switch to enable or disable location services.
To improve GPS accuracy
The first time you use the GPS function in your device, it can take a few minutes for your location to be found. To help the search, make sure you have a clear view of the sky. Stand still and do not cover the GPS antenna. GPS signals can pass through clouds and plastic, but not through most solid objects such as buildings and mountains. If your location is not found after a few minutes, move to another location.
