I've been using an S9+ since April 2018 for Android Auto with no issues until a few months ago when it started to freeze up. Spotify stops playing, maps don't navigate and the entire screen freezes. When I try to press the screen it goes black. I've tried 5 different cables including the one which came with the phone but no luck. Today I tried it with my partner's Samsung A8 and it worked perfectly and didn't freeze at all. I recently upgraded to Pie and the issue persists. Its driving me insane. From reading forums there's clearly an issue with the phone. Any suggestions?
