For example, if you have both home, work, mobile and any other phone number from a friend, you can use the Recent label to know which number he used lately, when attempting to call you. This helps you to choose the proper number when calling him back or sending him a text message. Naturally you’ll use the number tagged as Recent in order to make sure that you reach him on the proper device. These labels are automatically added by iOS to your contacts, whenever you receive a call from a specific contact. Tags are created no matter if you pickup the call or decline it.
iOS 10 “Recent” Label Facts
– the tag is added to a contact no matter if you saved a single phone number or multiple ones. That’s because you can also confuse phone number with FaceTime email ID.
– the Recent label is created to a contact’s number no matter if you receive or dial a call from or to the specific friend
– the label is active as long as the entry remains in your Recents Call History
Fact: the iOS Call History saves the last 1000 dialed or missed calls but only displays the last 100. This means that the iPhone can list up to a week of call history for the average users, but could go as short as 24 hours in case of hyperactive callers.
