Back when the Pixel 3 launched, Google introduced an AR feature to Google Maps called Live View. It's an augmented reality walking direction functionality guiding you through the streets. Well, today, Live View directions will work on more than just Pixel phones.
All Android handsets supporting ARCore and iPhones with ARKit can take advantage of the functionality. Once you select a waypoint in Google Maps, you can select walking directions and then tap on the Live View option at the bottom of the screen.
You can then look at the streets using the camera of the phone and you will get visual directions in real-time, hence the name of the feature. It's pretty neat so if you have the chance, try it out.
