What is green dot on text message icon?

A green dot on a text message icon typically indicates that the recipient is currently online and available to receive messages. This feature is common on messaging apps and social media platforms like Facebook Messenger, Instagram, and WhatsApp. When a user is online and active on the app, a green dot appears next to their name or profile picture, letting others know that they are reachable and responsive at that moment. This can be helpful for real-time conversations or urgent messages. However, it can also be a privacy concern for some users, as it reveals their activity status to others. Many apps allow users to turn off their online status or hide it from certain contacts.
