Lineage don't use Google services, so it won't use Google Wifi Location or Cell Tower Location Services from Google, but it should use the UnifiedNLP protocol to get location from several plugins, Mozilla Wifi Location Services, Cell Tower Location services etc, there's several modules, check F-Droid app store for UnifiedNLP and it should appear a list. If you don't have this location protocol installed then will be only possible to have location by GPS what is not battery friendly nor is as fast, there's a side project called MicroG that goes even further, not only replace Google Location services with UnifiedNLP modules but also simulates Play Services making possible to receive Google Services Notifications, but with lot more control and way better battery life. This phone Redmi Note 9 (Mediatek CPU) is not officially supported by Lineage or Lineage for MicroG, if that wouldbe the case, then free easy installed ROMs with everything working would be available, so or you ask this developer to make this Lineage port to have MicroG support (it needs signature spoofing on the ROM) or we must do it by ourselves, I myself will try to install Lineage and MicroG later when I have more free time too. But would be awesome if the develloper would bake it already in this ROM. Best greetings, and Many Thanks for Who's making the hard work porting Lineage to Redmi Note 9!
