On Samsung devices, a blue dot next to a text message indicates that the message has been sent as a Rich Communication Services (RCS) message rather than a standard SMS or MMS message. RCS is a protocol that enhances traditional text messaging by allowing features such as read receipts, typing indicators, group chat capabilities, and sending larger files or high-resolution images.
Here are some key points about RCS messages indicated by the blue dot:
Enhanced Features: RCS messages support more interactive features compared to standard SMS. For example, you might see when the recipient is typing a reply or if they have read your message.
Internet Connection: Unlike SMS, which uses the cellular network, RCS requires an internet connection (either Wi-Fi or mobile data) to send and receive messages.
Compatibility: Both the sender and the receiver must have RCS enabled on their devices and be using compatible messaging apps for the features to work. If the recipient does not have RCS, the message will be sent as a regular SMS.
Visual Indicators: In the messaging app, the blue dot helps users distinguish between standard messages and RCS messages, making it easier to understand the capabilities and features associated with each type of message.
If you see a blue dot next to a message, it typically means that you are utilizing the enhanced features of RCS messaging on your Samsung device.
