The unresolved security concerns with RCS encryption
Despite Samsung’s recent promotional announcements celebrating the success of RCS, the lack of end-to-end encryption for cross-platform messaging remains a glaring issue. Encryption is only ensured when messaging occurs from Android to Android, leaving a significant gap in comprehensive security across different platforms.

Google and the GSMA have acknowledged the need for encryption and speculated about its inclusion in RCS in future updates, though no definitive timeline has been established. This situation becomes more pronounced in light of tech giants like Google and Apple, who consistently advocate for end-to-end encryption on their respective platforms, seemingly overlooking this crucial security feature in RCS.
