I just got my flip 4 today and tried to connect it to my android auto. It will pair but not connect. I know my car supports it. I had a note 20 ultra and it worked beautifully. I have wireless android auto. I even tried connecting it using an USB but still got the error.
Known bug for people who used Smart Switch to transfer data from their old phone. I don't have the Reddit thread bookmarked, but the fix is simple. Clear the data and cache of Android Auto and Google Play Services.
You can do that by going to Apps>NameOfApp>Storage. There will be two buttons on the bottom, Clear Data and Clear Cache. Do both and reboot.
Just to let others know. Clearing the data did not work for me. It quit connecting about a week ago. It is not my cable as my old Galaxy 21 works fine.
I wasted half a day to try connecting my Samsung Z flip 4 through Android auto to my Toyota Camry 2022It worked fine with my other Android phone. Finally fix by changing the cable to an old one plus mobile phone cable. It show Android auto straight away when I plug in. So the problem is the cable, even it worked for another Android phone.
