Use Location Services
Some apps need to obtain your location information to provide better services. You can
enable or disable location services, and grant or deny permissions to access location
information for particular apps as required.
Enable or Disable Location Services
You can enable or disable location services in either of the following ways:
• Swipe down from the status bar to open the
notication panel (you can swipe further to
display all shortcuts), and enable or disable
.
• Alternatively, go to Settings > Location, and enable or disable Access my location.
After location services are disabled, your phone will prevent all apps and services from
collecting and using location information, with the exception of some built-in apps. When
these apps or services need to use location information, your phone will remind you to
enable location services again.
Increase the Accuracy of Location Services
You can improve the positioning accuracy of your phone by allowing apps and services to
scan for nearby Wi-Fi networks and Bluetooth devices or access supplementary data from
global navigation satellite systems (GNSS).
The feature availability varies by device.
Go to Settings > Location > Advanced settings, then set the options as required.
