To find your Android phone with Google, use Find My Device: open Find My Device in a browser, sign in with your Google account, and select your phone from the list. The tool shows your phone's last known location.
Google's Find My Device uses GPS, Wi-Fi, and mobile networks to determine your phone's location. If your phone is offline, the last known location is displayed. You can also remotely ring, lock, or erase your device.
Use Find My Device when your phone is lost or stolen. It works even if your phone is turned off, showing the last known location. For example, if you left your phone at a café, Find My Device can show you its location when it was last online.
Many people think Find My Device only works if the phone is on. However, it shows the last known location even if the phone is off. Another misconception is that it requires a special app - it's built into Android devices.
I once left my phone in a taxi. Using Find My Device, I saw its last location and retrieved it. The tool is more useful than most users realize.
