WhatsApp finally heard our prayers... The instant messaging app is rolling out a new feature that will allow users to delete sent messages. But because nothing is perfect in this life... You should know that the application will notify the other person that the message was deleted. You also have to delete the message within seven minutes of sending it. To delete a message, simply long press on it and then select the 'Delete for all' option.<br /> The highly anticipated feature will avoid discussions, misunderstandings ... and even save relationships!
