These guides explain what smartphone location technology can really do, what it cannot do, and how to configure an Android phone for reliable GPS tracking. They also answer common searches about missing phones, phone numbers, IMEI identifiers, SIM cards and offline GPS without pretending that an identifier is a magic location key.
If you want to use LocationOf itself, install the app only on a device you own or are authorised to manage. If your phone is already missing and LocationOf was never configured on it, start with the lost-Android guide and Google's official recovery tools.
