How do I switch on my location and change my location settings?

Your device uses a combination of Wi-Fi, GPS and mobile networks to determine your location. 

You can switch Location on and off, and change how your device determines your location.

Changing your location setting to a highly accurate setting will result in your device more accurately pin-pointing your location but will result in increased data usage and use more battery. A lower setting will be less accurate but save battery and mobile data.

Your device uses information from Wi-Fi or mobile data networks (or both) to help calculate your position. This option lets Google use its location services to estimate your location and improve search results and other services.

To set location reporting for Google, touch Google Location Reporting. You can turn Location Reporting and Location History on or off here

My places lets your device recognise your location to provide relevant information and services.
Add places such as Home, Work, and Car. This will allow you to use the Maps app, Wi-Fi, or Bluetooth to recognise locations. 

For example, set your Home location using Google Maps to search for your location or define your Car location by selecting your car from the paired Bluetooth devices.
