GSMA Releases RCS 4.1 Specs, Shifting Texting to gRPC for Faster Delivery and Lower Battery Drain

1 articles · Updated · Android Headlines · Aug 3

RCS Universal Profile 4.1 was formally published by GSMA, targeting the underlying performance, reliability and privacy issues still affecting cross-platform messaging.
gRPC replaces MSRP over persistent SIP sessions in the new spec, a backend shift designed to speed message delivery, improve stability in weak coverage and cut battery use in long chats.
4.1 also adds per-contact profile sharing controls, letting users expose or block their display name and photo in individual and group conversations instead of using one global setting.
End-to-end encryption interoperability across platforms and carrier networks is another focus, though the upgrade will take time to reach phones because apps and carriers must first adopt Universal Profile 4.0.
