Where can I find the lost address book software on my mobile phone?

1. It is preliminarily judged that the software may be hidden. It is suggested to open the application-menu-show hidden applications-and see if the software that is not displayed is checked (if it is checked, it will not be checked).

2. Check whether the icons are grouped into other folders.

If all the above operations fail, it is recommended that you back up your mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings (enter phone settings-reset-restore factory settings).

3. If the problem of restoring factory settings still exists, it is recommended to send the mobile phone to the nearest Samsung service center for testing and further processing.
