Android Auto Update 13.0 Prepares Support for Third-Party Calling Apps

Android Auto v13.0, a recent update for Android Auto, includes mentions of "external dialer" support which suggests that third-party calling apps may soon be supported on the platform. Currently, Android Auto only supports using the phone's default dialer app for making calls. The update includes flags such as "Dialer__external_dialer_allow_list", "Dialer__external_dialer_enabled", and "Dialer__swap_call_start_app_kill_switch".
