the MapFactor Navigator, free version 5.5.35 (2019) is used on a Galaxy S9 smartphone with newest android version and most recent maps (freeMap,Germany, updated). Unfortunately, the Navigator crashes sometimes during the journey out of unknown reasons, despite continued power- and GPS supply. The crash is complete, i.e. the Navigator times out at once, without prior warning and has to be started again with the same data. The crash is not related to specific regions, maps or time, but can happen everywhere and at any time.
Such a crash can be dangerous if it occurs in traffic stress situations when you do not know where to go!
Could anybody help?
