Use Location on a Mobile Device
A Lightning web component can use a mobile device’s location features to determine the
current location of the device and, by association, the person who is holding it. You can access
the device’s current location at a moment in time, or you can subscribe to location changes, and
receive updates to the device’s location when it changes significantly.
Location is determined locally on the mobile device, and doesn’t need a network connection.
LocationService does require access to platform-specific APIs that are available only within
compatible Salesforce mobile apps.
LocationService provides coordinate data only: latitude, longitude, altitude, and some motion details. It doesn’t include derived data, such as a physical address or map detail. If you’re using the location information to, for example, show a position on a map, you might need a network connection to receive map data, such as map tiles, and so on.
