RCS chats

Google Messages has introduced several features, including AI-powered scam detection and the ability to "unsend" messages, which have increased its popularity. The app includes visual status indicators for message delivery: a timer symbol for sending, a single check mark for sent, double check marks for delivered, and color-filled double check marks for read messages (if read receipts are enabled). It also has a typing indicator (three bouncing dots) and a lock symbol for end-to-end encryption. A red exclamation mark indicates message delivery failure. If no symbols are visible (except the red exclamation mark), it may mean RCS advanced chat capabilities are not enabled, reverting conversations to SMS or MMS. Users can check RCS settings in the app.
