When I go to send a new text. I start type in name and below it populates. I get names and numbers of contacts I had years ago but no longer in my contacts. What do I have turned on that it is doing this? TIA
Those with no "i" are still active contacts. You can't delete those without deleting the contact or the number/email address associated with the contact.
You might also check to see which accounts you have under Contacts in settings. I once inadvertently had contacts turned on for a very old email account. Once I realized this, I toggled that email account off, and my issue went away.
