Whatsapp is reportedly testing the ability to edit or recall messages that have already been sent. This means you can delete or revise a message even after your friend’s phone has technically received it. Say good bye to drunk and embarrassing texts.
The feature only works if the recipient has not read the message yet. On WhatsApp, this is signified by a blue tick mark. If the message has simply been received by a phone but not read — with grey tick marks, in other words — the feature still works.
The feature is currently being tested in the beta versions of WhatsApp on Android and iOS. The update adds “revoke” and “edit” options for messages that have not yet been viewed.
