What is not “production-grade” about PureOS? It’s the same OS they install on their laptops and the mobile options are baked into GTK. Do you use PureOS? As far as I understand it’s just Debian, with some changes to Gnome and both of those run in production in lots of places.

The HN audience can have those phones as daily drivers (some do). I am not suggesting that they are as good as iPhones.

I see your point. There's also postmarketOS; PINE64 PinePhone is listed as one of its primary supported devices[1].

postmarketOS mostly only supports well very old devices, and the Pinephone which is also based on completely outdated hardware. I wish there was something a little more recent with Linux support.

I had a look at OnePlus and checked wikipedia to know which country it comes from, and... wow :

* benchmark results faked by software

* personal data collection

* backdoor

All of these do not appear on the English page so there's a link to the French one : https://fr.wikipedia.org/wiki/OnePlus#Controverses

Yep..... I'm not endorsing them per se, I'm just saying work is going on to get them to work on pmOS (and Mobian).
