How to track the location of a mobile phone

The method for querying the location of the mobile phone is as follows:

1. Apple device: If the phone loses its query location, you can use the "Find My iPhone" function. Visit the iCloud website to log in to Apple? ID, select the "Find iPhone" option, view the device location, make a sound, lock the device or delete the data on the device.

2. Android device: If the phone loses its query location, you can use the "Find My Device" function. Visit the Google search page, log in to your Google account, and enter "Find My Device" in the search box to view the location of the device, play sound, lock the device or erase the data on the device.
