A long-requested feature for Android users switching to iPhone is the addition of T9 dialling. This is a shortcut to dialling phone numbers from your address book, by typing in letters on the keypad.
For instance, to call John you’d press 5 6 4 (for J O H). On many Samsung and other Android phones, this would search for the closest alphabetical match to a person’s name in your contacts. iPhone has not had this feature … until now with iOS 18.
