Ans: Half-swiping is the act of reading your friend's text on Snapchat without notifying them that you have done so. You can half swipe on Snapchat by: ➼ First, open an unread chat message on snapchat. ➼ Then, gently tap on the profile icon of your friend.  ➼ Finally, drag your finger left to right across the screen. You can read the text, but it won’t be marked as read!
