Quote:WhatsApp is working on a new feature that will allow users to send self-destructing messages. This feature is currently in development and has been spotted in the WhatsApp beta for Android 2.19.275.
 
While self-destructing messages do not prevent users from taking screenshots or pictures of the screen, it does add some level of privacy to message senders and is a popular feature in other messaging apps.  

Based on screenshots found by WhatsApp news site Wabetainfo.com, the 2.19.275 beta build includes a new feature called "Disappearing Messages" that can be enabled through the app's Group settings.
