The messenger WhatsApp has added a feature that allows you to send disappearing photos and videos messages. You can view them only once, after which they will be deleted.
To send a disappearing message, open a chat with your conversation partner and go to the menu to select a photo from the gallery. When you’ve selected the photo you want, click the one in the gray circle at the bottom left. Then send the disappearing photo.
Such messages will be marked by a special round icon with a one in the middle. After viewing, the message will be labeled “open” and will no longer be available.
Such files will not be saved in the photo and gallery, they cannot be sent. They will be available for 14 days after sending, after which they will disappear forever.
