After giving it a lot of laps and wasting time, I have verified that if I activate Samsung Pay on my Galaxy S-20-5G smartphone, I cannot use the call button to Google Assistant from the steering wheel of the car. It is important to me to have access to Google Assistant from the wheel, since the alternative of using the voice to activate it with 'OK Google', with the noises / music that is usually in the car, does not work well enough, so I have been forced to uninstall Samsung Pay, with some regret because otherwise it is a service that works frankly well. I hope that in a future Samsung software update this problem will be solved and I can continue using Samsung Pay again.
