How do I use Android Device Manager to find my phone?
Open the Android Device Manager to track and manage your devices. Android Device Manager can be accessed in two different ways:
Android Device Manager app – Download the Android Device Manager app from the Google Play Store on another Android device. If you are using the app on another person’s Android device, you can log in as a Guest. Log in with the Google account that your missing Android device is signed into. The Android Device Manager app is not available on iOS; use the website instead.
Android Device Manager website – Visit google.com/android/devicemanager and log in with the same Google account that your missing Android device is signed into.
Select your device. If you have a number of Android devices linked to your account, you will be able to select which one you want to track and manage by clicking the name of the active device and selecting the one you want from the menu.
Locate your device on the map. If location services are enabled on the device, you can usually track it on the map. If your device has a GPS signal, the map should be reasonably accurate. If your device only has wireless location enabled, it may be more inaccurate or may not even appear at all.
If the Android Device Manager fails to find the correct location, it will display a circle that the device should be somewhere in that area. This will help you track down the correct location by retracing your steps.
If you are trying to locate your device nearby, you can set it to ring by clicking the "Ring" button. Your device will ring at full volume for five minutes or until the device gets unlocked.
If you are worried about your device falling into the wrong hands, you can lock it with a new password by clicking the "Lock" button. You will have to enter this new in order to unlock the device. You can also set a message that will be displayed on the device's screen.
Erase your device. If you're afraid that your device has been stolen, or you think it is lost for good, you can erase all of the data and settings by clicking the "Erase" button. This will perform a factory reset on the device. If the device is not presently online, it will start the reset the next time it connects.
