It used to be easy. I have no idea when I lost the ability to delete text messages, because I haven't needed to do it for a long time. With iOS version 10.3.3 on my iPhone 5, there doesn't appear to be any way of deleting a text message, unless I delete the sender, in which case it will delete all of his messages. How do I delete individual messages?
The problem I'm having is that an idiot friend of mine has suddenly started spamming everyone in his contact list with stupid photos that he thinks are funny. I don't want to hurt his feelings by telling him to stop, but I'm getting close to that point.
