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.

Android's open-source nature allows users to explore apps beyond the Play Store and experiment with custom ROMs, but it creates security challenges for developers. The Play Integrity API has been developed to ensure applications run only on genuine Android devices. Custom ROM users face obstacles as more apps implement Play Integrity checks, leading to operational failures, such as with the Authy app on GrapheneOS. Google’s Shawn Willden acknowledged the dilemma posed by Play Integrity, stating unofficial OSs are assumed to be bad. However, he mentioned the possibility of developing a certification process for third-party ROMs to pass Android’s Compatibility Test Suite, though interest in such a program is low. Most Android users prefer a seamless experience on mainstream devices, prompting discussions about collaborating with developers to create apps that do not rely on Play Integrity checks.

Apple is expected to embrace Rich Communication Services (RCS) messaging, which will improve texting between iPhone and Android users by providing features similar to iMessage, such as high-quality media sharing and typing indicators. Despite this upgrade, iMessage will remain exclusive to iPhone users. The integration of RCS into iPhones is anticipated to happen in the fall, aligning with Apple's typical update schedule. The Department of Justice's antitrust suit against Apple has raised concerns about iMessage's exclusivity, but Apple has defended its stance and highlighted its commitment to RCS for enhancing cross-platform messaging.
