And in the details, WhatsApp users will be allowed to enable the feature at any time they want. Once the feature is enabled, all new messages will expire after only seven days. Sources say that if you do not open chat for 7 days, messages will disappear.
And if you backup your conversations before they disappear, you will find them on Google Drive. However, if you plan to restore those disappeared messages from a backup, you won’t be able to find them as they will be deleted.
WhatsApp will also allow users to forward or take a screenshot of the disappeared messages, in addition to allowing the hidden photos and videos to be saved in the camera file, so, there will be a Save to Camera Roll option, which you must enable manually.
It is mentioned that the message disappearance feature will be available to users of Android, iOS and KaiOS devices, and it will not be enabled by default, so users must enable it manually, according to what the Indian Express Online newspaper reported.
