Phone/tech question.......

....everytime i plug my phone into the aux channel on my car to play from spotify i keep getting the google gemini pop up

When i switch it off in settings i get the pop up asking if i want to switch it on and it doesn't let me play from spotify.

I have a samsung and it happens with my son's Samsung too. I don't get this problem when i connect to my headphones.

It's really pissing me off and i have a long car journey this weekend...does anyone know what to do?
