Will touching an infotainment screen while driving be banned?

Is it illegal to touch a phone being used as a sat nav while driving?

I put my smartphone in a holder attached to the dashboard and then use it as a sat nav. Sometimes I need to touch it to see how far ahead a traffic jam is going on. Am I breaking the law if I touch it...
