Android Auto Heating issue

I bought a Flip 4 a few days ago, and I'm facing a heating issue when I'm using android auto 

The problem is I can't use the phone because it is hot and to much lag; even when I was using the S21 ultra before, its the same issue

Please, can anyone solve my issue here? I like my new phone, but it will be useless for me without android auto 

Thank you.
