Viv0 mobile phone information software has been deleted, so I can't receive messages. How can I make it right?

1. It is recommended to upgrade the firmware and restore the software first. If the mobile phone problem cannot be solved, please take time to go to the after-sales service center for testing and handling. After-sales service center address inquiry method; Enter Settings-More Settings-After-sales Service.

2. Enter official website-Service-Search for the firmware upgrade package of the corresponding model mobile phone-Click Resources to download the firmware upgrade package of the corresponding model mobile phone. Please back up the information before upgrading.

3. You can use the mobile cloud disk or vivo mobile assistant to back up the data on your mobile phone. The method is as follows:

Copy and paste the files that need to be backed up to the file management-cloud disk (network is required for backup, so it is recommended to connect the mobile phone to WiFi before operation).

Some models do not have a cloud disk when they leave the factory. You can connect your mobile phone to the vivo mobile assistant on the computer-vivo cloud-enter a vivo account and log in-cloud file-upload-and select files to open and upload.

Go to vivo Mobile Assistant-My Mobile Phone-Data Backup-Backup-Check the option to backup-and start the backup (this backup is to backup the data on the computer).
