Running de-googled Lineage OS (Android 10 equivalent version). Biggest drawback for me is maps. I make do with OSMAnd+ but I have to search on Google Maps, get the coordinates and paste into OSMAnd+. Other than that no issues
It would be nice, if you could incorporate those missing locations into OpenStreetMap once you come across them. Afterwards everyone else will benefit from your contributions, as they don't have to lookup the location on Google Maps anymore. :)
OsmAnd actually has a map editing plugin. Another great application for improving OpenStreetMap is Street Complete. It is a good way to kill some time while waiting somewhere with incomplete OSM data. ;)
