GrapheneOS Rebuilds Its Messaging App, Aims to Cut Google Out of RCS
GrapheneOS Overhauled Default Apps and Secure Clipboard
GrapheneOS is overhauling its bundled apps, starting with a complete rewrite of its Messaging app in Android Compose, releasing later today. The team plans to add RCS support with end-to-end encryption via MLS, aiming to eventually replace Google Messages and reduce dependence on Google and carrier infrastructure. They're also replacing the outdated AOSP Gallery and possibly the keyboard, with new hires accelerating progress.
RCS isn't an open platform in practice. It isn't even as open as SMS/MMS. It heavily depends on proprietary Google and carrier infrastructure in practice.
