How to Delete/Revoke Sent Messages on WhatsApp

WhatsApp has finally rolled out the delete/revoke feature through the latest update of the app. This means the latest version of WhatsApp allows you delete sent WhatsApp messages from the recipient’s phone if they were sent to them in error or if there are mistakes while sending it. The purpose of this is to reduce the after effect of typos which is possible when typing on our phones. This will also come in handy when you mistakenly send messages to someone whom the message isn’t meant for. 

For instance, you want to send a love message to your girlfriend or boyfriend but mistakenly send it to your dad, mum, or even religious leader. You know before now, once you make the mistake, you have no other option and it remains like that. But now, once you make such errors, you simply delete or revoke the message within 7 minutes stipulated time. After seven minutes, the message stays sent forever.

The recipient from whose phone a message is deleted will be alerted that a message has been deleted. They will see a notice that says “This message was deleted” at their end. If you ever see the same message at your end, it means that the person you are chatting with has deleted a message they sent to you.
Unfortunately, the WhatsApp team says you will not be notified if the deleting operation failed.
