Many people don't realise this, but Google Maps navigation has two views: a first-person view (where the arrow faces forward at all times) and a map view, which shows a more traditional map and rotates the arrow. If you've somehow gotten stuck on the second, here's how to go back to regular navigation.
Some of you may know this already, but now that I've seen a few people get "stuck" on the map view (shown below) without knowing how to get back to the first-person view (shown above), I figured it was worth sharing this tip.
Just tap the compass icon in the corner! This should switch you to the first-person navigation view that -- in most cases -- is much easier to use (especially while you're driving). If you prefer the map view in any scenario, you can just tap the compass icon again to go back.
Again, this may be old hat to some of you, but it's kind of a "hidden" feature that's very easy to accidentally toggle if you don't know what it does. Hope this helps some folks out there.
