The white dot that appears on a Facebook profile picture typically indicates that the user is currently active or online. This feature is part of Facebook’s presence indicators, which show whether a user is available to chat or interact in real-time. When you see a white dot on a profile picture, it means that the person is active on Facebook at that moment, either on the main site or through the mobile app.
In addition to the white dot, Facebook may also display a green dot or other indicators to denote different statuses, such as “active now” or “active recently.” These indicators help users understand when their friends or contacts are online and available for communication. However, it’s important to note that users can control their visibility and may choose to appear offline even if they are active on the platform.
