Prior to iOS18, the incoming/outgoing call history display in the Phone app matched the CallDirectory content, but starting with iOS18, changing the information tied to the same number results in the incoming/outgoing call history not matching the CallDirectory content, as it remains unchanged before the change. Is this a strongly intended change? If not, we would like to have it reverted back to the way it worked before iOS18.
Befor iOS18
Register the target phone number and name1 to CallRirectory
Incoming call using the target phone number
The target phone number and name1 is recorded as an incoming call history
Register the target phone number and name2 to CallRirectory
Incoming call using the target phone number again
The target phone number and name2 is recorded as an incoming call history
Also 1st incoming call history’s name is changed to name2
After iOS18
Register the target phone number and name1 to CallRirectory
Incoming call using the target phone number
The target phone number and name1 is recorded as an incoming call history
Register the target phone number and name2 to CallRirectory
Incoming call using the target phone number again
The target phone number and name2 is recorded as an incoming call history
But 1st incoming call history’s name is still name1
Why does this difference occur?
