Both Apple phones know their id and password, so how can they find out each other's information?

1. It is best not to share an ID account, otherwise important data files cannot be backed up independently, and once lost, they cannot be retrieved.

2. Also, even if you share a file, don't turn on all iCloud synchronization options, otherwise the data information will be synchronized with each other, resulting in confusion of mobile phone information.

3. Click Settings -iCloud, and then turn off all options and functions in iCloud that don't need to be synchronized with each other.

4. The automatic download function should also be turned off. Click Settings -iTunes Store and AppStore, and the function of automatically downloading software should also be turned off.

5. Set-Message -iMessage, and turn off the function of information synchronization, so that messages will not be synchronized with each other. (If you want to watch it, don't turn off iMessage, it's synchronous. )

1, first of all, the location function should be realized, that is, the mobile phone must turn on the location service to' find my iPhone' or the places it frequents.

2, the second is to use mobile phone positioning, which must be supported by Apple 5 or more mobile phones.

3. If the above two adjustments can be made, you can locate the location of the mobile phone in the place where you often go-Privacy-Location Service-System Service.
