Why doesn't the updated version of Red Rice note phone have call records and text messages?

This is mainly caused by the following reasons:

1, the system or software function is unstable before the system upgrade.

2. The compatibility of brush package is not good.

It is suggested that the mobile phone must make a backup of relevant information before updating and upgrading, otherwise it will be more troublesome if something goes wrong.

It is recommended to use cloud disk to back up common data, which is fast and convenient, and will not be lost or unrecoverable due to system failure and hardware damage (card problems).

For example, 360 cloud disk, Baidu cloud disk and so on.

Backup and recovery operations are in the same location, so it is recommended to operate in WIFI environment. Uploading and downloading photos will consume a lot of traffic.
