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?
