Will the data on my phone be safely removed when I bring it back to AT&T?

Episode 986 (2:06:38)

Dan from Virginia

Dan has an HTC One phone that suddenly died. He needs to return it to AT&T to be replaced and he's concerned about how his private data will be handled. Leo says who knows? They can pull things off of it, even if it's broken. In reality, they'll just destroy it and move on. Unless Dan is a "person of interest" by the FBI, AT&T doesn't care. They'll just destroy it since it's dead.
