Locations services is currently not activated on NextD even if it is switched to ON. The masjority of use cases of NextD doesn't require location services. However, some apps such weather, maps, and certain sports apps do benefit from or require the device's location to function.
In these cases, the user can install the "Fake GPS" app from Google Play on NextD to provide a peudo-location to the running apps. You will need to check the "Allow Mock Locations" setting under Developer Options in system Settings.
