Google Messages has introduced a Remote Delete feature, enabling users to delete sent messages from one device while using another, provided both devices have the app and are logged into the same Google account. This feature allows users a 15-minute window to remove messages, which will be replaced by a 'Message deleted' placeholder in the chat. The update is part of the RCS Universal Profile 2.7 enhancement, and it aims to enhance user experience, especially as Google’s focus on generative AI grows. Additionally, Google Messages now supports a floating action button for easier AI interactions.
