WhatsApp is currently reportedly working on a feature that is similar to WhatsApp's existing feature of Expiring Messages. The new feature is called Expiring Media, and as the name suggests, it is responsible for media files including photos, videos, and GIFs disappearing from the recipient's phone. The content will ''expire'' once the recipient leaves the chat window. The feature is kind of like sending media files over WhatsApp chats that will appear temporarily only.
The feature could be useful in a way that it would automatically clear media files from a device to prevent the recipient's photo gallery from being stuffed with files that recipients keep collecting without deleting, as we don't frequently clear files from chats, and as a result, they end up occupying storage. It is likely to save users from the hassle of manually deleting unwanted media files.
Apparently, the Expiring Media feature can be enabled by tapping on a timer button after downloading the media file in a chat. The expiration for that particular media file will then be activated. Files that are activated for expiration will disappear as soon as the recipient leaves the chat window.
It is reported that the feature will be rolled out to Android first and then iOS eventually.
