How can I see a previous message on Snapchat?
If you want to save a snapchat message: simply hold your finger down on the text you wish to keep-you will notice the text is now highlighted in grey and a little bubble will pop up saying “save in chat.”
If you decide you no longer want to save a particular msg, hold finger down again and then it will say, “unsave in chat” with the msg returning to its original white background. If you exit a convo and have not highlighted the text, upon return, you will find that your messages have permanently disappeared.
