The users are finally going to get a feature on WhatsApp, which was the most anticipated one too for a long, long time. The new feature will basically let the users delete or recall the messages after they have been sent. In order to access this new delete functionality, all you need to do is to tap and hold that message.
After that, you will be able to choose yourself whether the message should be deleted for everyone or just for yourself. If you go for the option of deleting it for everyone, then the same message will be deleted from the chat windows of the recipients too. The screen will then show ‘You deleted this message’ in your window, while for others it will show ‘This message was deleted’.
This feature is rolling out at the moment, but the update is not available so far, and hence you will not be able to use it right away.
