How do I locate a missing device?

You can only locate your device and may remove all your personal data from this phone if it meets all the following conditions:
    1. A personal Gmail account is still logged-in on your device.
    2. This device is connected to a Wi-Fi, 3G, or an LTE network.
    3. Android device management is enabled in the device’s settings.  Note: This is enabled by default, so it should be met if you never changed these conditions.  If you don’t have the Android Device Manager or Gmail app in your device, download them from Google Play.
If all of the above are applied to your device, use this link to help you locate it or remove all your personal data on your phone.
