I own a #FLX1 phone and use it as a daily driver. Recently @furilabs@fosstodon.org issued a new update for the software on the phone (#FuriOS) - 14.1.0 . There is a rewrite to the phone app, that is greatly improved.

There is a single place for all the phone stuff. I can call from the phone book. I really like it. It's a nice improvement over the combination of gnome-calls, gnome-addressbook and chatty, that are not really well-integrated.

Indeed I lost the support XMPP and Matrix that #Chatty has. But I mostly used XMPP support for notifications, and relied on #Dino anyway. And failed to use it for Matrix and used #Nheko instead.

However, what I dislike is that the code seems to be geared for internal development. The app seems to be:
https://github.com/FuriLabs/telephony

Not very inviting. No place to report bugs. I had a major problem (if I lock screen and get a call, or even dial through the command-line interface - telephony-cli, quite nice - I get a very-partially-functional interface similar to gnome calls that fails to be controlled (so mute or disabling speaker is impossible) - "libcall"(?). I ended up contacting support and sound that this is because of functionality not yet implemented.

I appreciate the FuriLabs folks very much. But I keep getting memories of Ubuntu of 10 or 15 years ago, or working on their own (even with libnih - a name that they actually used in upstart). This is a phone with its very own and somewhat different than others stack. And now it has just gotten more different than others.

Anyway, I hope it works well.
