Google has implemented a measure to enhance the security of its messaging platform by preventing devices that fail Play Integrity checks from sending Rich Communication Services (RCS) messages. This decision has led to users experiencing vanished messages without explanation, particularly affecting those with rooted phones or custom ROMs. Recent developments indicate that Google Messages will now inform users when their devices do not meet security requirements, with a new text string stating, "Your device does not meet security requirements," expected to appear in the RCS settings. Additionally, a "Details" button is anticipated to provide further clarification on RCS limitations. This change aims to improve user communication and reduce confusion regarding message disappearances.
