Facebook is the most user social media application across the world but that also makes it users exposed. Although it is a person’s choice what they decide to share but other people do not have an option to share those photos and videos unless they take a screenshot. You can simply open the page and take a screenshot. Facebook screenshot notification is not a feature yet. Therefore, the user will not be notified if someone takes a screenshot of their profile.
