A cloud-based solution for mobile phone contact loss

Background Technology:

As the mobile phone business continues to grow, each person has a mobile phone with a large amount of contact information, and the management of contact information is relatively cautious, if you accidentally delete one or both of them, you can simply retrieve them, but if you accidentally lose them all, you will not be able to recover them. Unless you have a backup first, you will be able to celebrate it. If you do not have a backup, it will be too much trouble, however, when a user who is not familiar with the mobile phone when making a one-Click Reset to restore the factory settings for the mobile phone, or some users forget to back up the information first, the contact information cannot be recovered. Therefore, we can solve this problem through an automatic detection and restoration method, which is easier to operate and can be automatically processed.

Technical content:

Mobile phone contact's automatic detection and restoration methods include: record module, storage module, detection module, cloud backup module, and restoration module.

The record module records the user's mobile phone contact information (such as the contact name and phone number) and stores the information in the storage module.

The detection module monitors the information changes of mobile phone contacts, including the details of adding, deleting, and modifying a contact or a contact. If the information of a contact changes, it is automatically backed up to the cloud storage module. At the same time, check whether there is any information in the entire contact list. For example, if the user restores the factory settings with one click on the phone or deletes all contacts, when no contact information is found in the contact's storage module, the detection module automatically restores the backup contacts to the contact information list. This is simple, convenient, and practical.
