Today 10 years ago I got a Firefox OS phone
(jemmy.jeena.net)
Today 10 years ago I went to Poland to buy a Phone with pre installed #Firefox OS on. The Phone was a Alcatel One, so very shitty. Two years later I installed Firefox OS on my Nexus 5 instead.
It was a very good concept, but sadly rolled out on too shitty hardware so it never caught on.
If you are still interesting in Linux phone, consider looking at PinePhone Pro. I would recommend it only for experience users and the phone experience is far from Android, but software is catching up. Check @linuxphones
P.S. writing this comment from PPP :)
I know about the PinePhone Pro and I am quite experienced.
But even hardcore hairy dude like Drew Devault disavowed it (source).
It seems that the main complaint is calls and SMS. I use different distro (Arch, btw) with FOSS firmware for the modem and calls / SMS work fine for me.
