How Can I Make The Print On My Inbox Messages Larger And Darker

Why do messages on Facebook Messenger sometimes change from "seen" to "delivered"?

Paul Olaru is correct.  I am not sure what version of Messenger you're using, but "Seen" means the person opened their chat or Messenger to the conversation.  My version of Messenger doesn't have "Delivered" as a status message, but it says "sent" if the message has not yet been opened by the recipient (Apple's iMessages shows "delivered" if the message was sent but not opened, and "read" if it was opened).  In Messenger specifically a "seen" message may have a little circle with a miniature of the recipient's profile picture next to the message to indicate that she's opened it; a "sent" but not opened message has a check-mark next to it.Edit: Combined three answers on merged questions.  This question is very merge-worthy; I rarely go more than a couple days without a new A-to-A on the exact same question.  I won't be answering it in the future, nor any similar question, because there's not much to add.  Hopefully one of these answers will be helpful.Originally Answered: I sent someone a private message on Facebook, and their profile picture icon showed up, indicating that they read it. When I look at the icon next to our last two conversations, it is a white circle with a blue checkmark. Does that indicate that they marked it as unread or deleted the message?It usually means they haven't looked at the latest message in the conversation, whatever that may be.  You got the "seen" icon for any messages that were there the last time they went into the conversation, but if you have sent a new one since then they might not have "seen" it.I've seen numerous questions on Quora asking about the following: If you had a "seen" icon and it changed back to a blue circle without you sending any more messages in between? That I think must be a database glitch—I have attempted several times to recreate such a situation with my computer, phone, and a dummy FB account that I mostly use for testing, and I wasn't able to recreate a situation like that when I experimented with it just now.  I've never seen it in the "wild", either.  And as of today, 20 September 2015, FB aren't marking messages "Delivered" on the desktop chat window either.Whether the other person deletes or marks unread a conversation affects only the way it shows up on their device, not yours.
