Resetting settings on devices with the Android operating system is a common action that allows you to roll back the device to factory settings.

However, this action, in particular "hard reset", is fraught with the removal of the book. Devices include Android smartphones and tablets.

The developers of the Android operating system provide backup and data synchronization, which are enabled by default in the system settings. If at least one of these actions was previously performed, a copy of the data was saved on the Google server, and address book recovery will not be difficult.

Otherwise, you will have to "get" contact information from the "bowels" of the file system using special software.

To restore the address book from the Google server if the Internet is available on the device, follow these steps in sequence:

• Open the main menu and select "Settings".
• In the list that opens, find "Accounts and syncs" and click on it. Depending on the android version, this item may be called differently, but the keywords "accounts" remain unchanged.
• Select add account and point to Google in the list that appears.
• In the window that appears, select an existing one and enter the account name and password in the appropriate fields.
• Open "Contacts" and by pressing the button that performs the "menu" function, call up the list of available operations.
• In the list that appears, find and select "Import / Export".
• Point to the previously entered google account and click "Next".
• Within a short period of time, the contacts will be synchronized. Synchronization speed depends on internet bandwidth.

Restoring contacts on android from an account when there is no Internet on the device:

• Sign in to your Google account through a computer or other device connected to the internet.
• Type in the address bar of the browser http://google.ru, or go to the Google site through search sites.
• In the upper right corner, click on the login button and enter your credentials.
• If you have forgotten your password, use the password recovery function.
• Upon successful login, select "Contacts" from the list of services, which will open the page with the address book.
• Select "Export" and in the window that appears, agree with the proposal to switch to the old version by clicking on the appropriate item.
• Mark the contacts you need and export.
• Transfer the created file to the device.
• Import contacts to your smartphone.

After these steps, the address book should be restored. If the contacts were not restored or the address book is not up to date and the necessary phone numbers are missing, proceed to restore from the file system.

Creating and Restoring Contacts Using a Backup

Backup of the address book is performed by the "Export" function in the "Contacts" menu. The memory to save should be specified as external, since the internal is cleared. The result of the export is a created file with the .vcf or .csv extension, which stores all contacts from the address book.

Importing contacts is done in the same way, with the exception of choosing Import instead of Export.

How to restore contacts on Android from the file system after a factory reset

Deleted data is stored on the physical device until these sectors are written to or low-level formatted. File recovery is implemented by special application software.

The difference between such programs lies in the graphical user interface, while the algorithm in most cases is used the same. Programs are divided into paid, shareware, free.

The existence of application programs for recovering deleted data on physical storage provides users with the opportunity to recover lost data on their own, eliminating the need to contact specialists and service centers. However, other technical difficulties may arise, such as installation problems, getting superuser rights, etc.

It is possible to restore both by connecting the device to a computer via a USB cable, and offline by installing the appropriate application on a smartphone. You must first be rooted before performing offline recovery.

• The scanning process will take some time, resulting in a list of deleted data.
• Select and specify a folder to save.
