If your phone is compatible then you will get a update notification for Whatsapp. The message recall option is similar to gmail's undo. Please note this feature is time sensitive. This feature won't work if you are trying to delete a message older than 7 minitues.
How this feature works?
When you delete a message for everyone, The Whatsapp will send fake copy of message to the recipient. When the recipient will recieve your copy, his device won't show you the notification and it won't save it in its chat history, but it will check if the ID of the message in the database :If it will find the message, the message will be correctly revoked. This is the backend process.
Actually this feature is launched on GB Whatsapp before. To recall a message you need to long press the message that you want to delete. After that click the delete option on the top of the screen. you will see have 3 option. Delete for Everyone , Delete for me and cancel. The Delete for everyone option will delete the message from sender and reciever. Delete for me option will delete the messege on sender side, And cancel button simply close the delete menu.
I hope this blog find helpful for readers. Stay tuned for future updates.
