We do use electronic compass. That’s how google maps on your phone knows which way you are pointing.

Untrue. Google maps infers direction from multiple time-separated locations - that is, your velocity vector. If you don't move, it guesses - and is quite often wrong.

  • No. You can see blue emit from your position in the direction your phone is pointing. If you turn around, it will turn around too. It uses the built in compass for this.
