- IAmBroom 10mo agoUntrue. 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.
- wodenokoto 10mo agoNo. 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.
