| TL;DR When the Mobian first time setup wizard asks if you want to send location data to Mozilla Location Services answer "Yes." Use either [[maps|Maps]] or install [[puremaps|PureMaps]]. Run one of those apps in the background (or foreground) when you're traveling around with WiFi and Mobile Data enabled. For vehicle navigation, position your phone to have a good view of the sky when inside, and keep it in the open every once in a while for at least a few minutes so that it can find the satellites. | TL;DR When the Mobian first time setup wizard asks if you want to send location data to Mozilla Location Services answer "Yes."
