A cypherpunk friend of mine, who is a hacker and a computer programmer, has an MMS group where his friends organize a dungeons and dragons game.She told me that one of her friends installed it at first, but it totally broke all of his MMS groups, so he uninstalled it so he could keep talking to his friends. My partner is a student, and she asked some of her classmates to install Signal to discuss study group stuff.It would have been much better for her to use her old SMS/MMS app for that message, and Signal for Signal messages. But then my sister got really frustrated because she wasn't able to send a big group message to a bunch of people, many of whom weren't using Signal, due to weird MMS bugs in Signal for Android. It's great and they all loved it right away. I recently convinced all of my immediate family to use Signal, and created a family Signal group.

I've fixed it before, but the easiest solution is stop making Signal the default SMS/MMS app, and use another app for it. Someone sends a group message, or tries to text a photo, and Signal won't let me see what it is. I have never had MMS 'just work' in Signal for Android (or in TextSecure before it).Signal is great for sending encrypted messages and having encrypted voice calls with other Signal users, but pretty bad for SMS/MMS on Android.
