I'm having exactly the same issue. When I connect the Mi 9T to my car, the Android Auto icon shows in the Notification bar for a brief moment, then disappears :(. I've tried with several cables, allowing autostart, enabling all the permissions, disabling battery optimization... unsuccessfully. |
Android Auto is working great with my old OnePlus 2 and the same cables and same car... I'm seriously considering returning my Mi 9T and going back to my previous phone.
