Why doesn't the phone display the call record?

There is no call record on the mobile phone, which is generally caused by a problem with the mobile phone system.

The recommended operation is to back up the important related data on the mobile phone before resetting it.

In other words, in general, the factory settings are restored.

The problem can be solved by basically restoring the factory settings.

If the landlord's mobile phone has been used by ROOT before, it may be necessary to refresh the official system package to restore the display of mobile phone call records.

Because after ROOT passes, it is easy to cause system instability, or the related support functions of call records may be deleted by the landlord.

At this time, the normal use of the mobile phone can be restored by strong brushing.
