Find My Device is a lifesaver feature for the absentminded among us. Even if you've just left your phone in the couch cushions, you can use the feature to ring it. Now, the service has picked up a new feature that can help in more dire circumstances: it can now show where your phone is on an indoor map of some large buildings, like malls and airports.
Google's been messing around with indoor maps for years; you can check the layout of many department stores and other large indoor spaces in Google Maps. Find My Device can show on those maps where your device is located. Here's the changelog for the latest version:
• Support for work profiles
Your best bet is probably still to just keep track of your stuff, though. Grab the updated app on the Play Store, or sideload yourself from APK Mirror.
