If you want to delete all the ring history on your iPhone, there are a few different ways to go about it. The first option is to go into your Settings app and select General. From here, you can scroll down until you see the option to “Delete All History”. Tap on this and confirm that you want to delete all of your history. If you don’t want to delete all of your history, but just the ring history for specific contacts, you can do this by opening up the Contacts app and selecting the contact that you want to remove from the ring history. Next, tap on the three lines in the top left corner of the screen and select “Edit Contact”. From here, tap on “Ring History” in the bottom right corner of the screen and select “Remove From Ring History”. Finally, if you just want to clear out your current ring history without deleting any old ones, you can do this by opening up the Phone app and selecting Call History. From here, tap on a call that you want to remove from your ring history and select “Remove From Ring History” from the bottom right corner of the screen. ..
