TL;DR
- Google Maps appears to be working on a new power saving mode for navigation.
- The mode would eliminate almost all UI elements and extraneous map labeling from your view.
- Power saving mode limitations could prevent it from working in landscape or with public transit
Try OsmAnd, I don’t have any problems with it for so many years. It’s heavier than CoMaps but also so much more powerful
I got scared off by the interface, I might give it a second try. My solution to the issues of COMAPS is to heavily bookmark geolocations in other apps. Resorting to proprietary solutions for emergencies (Yandex is pretty great outside countries like the US which do not like them).
