Getting cameras working was a prerequisite for FCC certification (which requires all hardware to be operational for testing), so no - it was quite obviously a higher priority.
That said, we’re already starting to get things needed for MMS in place. There’s an updated version of libqmi heading to byzantium right now, which will allow us to backport transfer-route MT patch in ModemManager, which is needed to handle MMS on some networks (and unbreaks SMS being stuck after receiving a MMS on those). Afterwards I plan to take a look at having mmsd package uploaded to byzantium, at which point it will be “just” a matter of integration into Chatty.
