Google Maps Compass Rose Tip
Recent versions of the Google Maps app for Android have a small “take me to my current location” button in the upper-right. After looking all around, one tap of that button will zoom you back to your current location.
What happens when you tap it again? It changes the layout so instead of North being “up”, it uses your digital compass to change the direction of the map according to the direction of your phone. Kinda cool, take a look!
