Yes I do have the new Android Oreo OS. And maybe that's the blame? If I make a call and hang up after a few seconds it will load Google Maps and try to navigate to that number. I have done a factory reset and it still continues the only way make him stop is to disable the app but obviously no Maps! If I answer a call I hang on the maps which will also interrupt my navigator for when I'm in there. Extremely frustrating and it seems to be a total software issue I've cleared the data and both apps and again I've already Factory Wiped. Really would like to find a solution.
