Picked up a PinePhone a few months ago but didn't get a chance to really play around with it until the last week or so. It shipped with postmarketOS which I played around with, but I had some issues pulling down software from the distro's repos even after manually updating to the current version of it, and distro hopped over to Mobian since I'm more familiar with Debian, and it rules. I never thought I'd see a real commercial phone running Linux outside of some limited run novelty phone or an Android environment running X11. Apps are mostly responsive, and the shipped apps are (mostly) very touch screen friendly. The coolest part of this for me is you can use a USB C hub on the PinePhone to connect this phone up to a real screen and keyboard, like you can on some Android phones, but it's a real Linux desktop and not an approximation of one.
I'm going to pick up a pay as you go SIM card to toss into this thing and see if I can use it as more of a real phone rather than just a wifi device sometime this week.
I meant outside of firefox since yeah they got rid of PWA support on desktop firefox, which was really sad.
Ah, yeah haven't tried it. It comes with Firefox ESR and I haven't even bothered upgrading it to the current stable branch let alone put another browser on here. Mobian's wiki says GNOME web works well on the touch screen, but I'm not sure if it has the PWA feature. I know Chromium does but based on the wiki page it looks like it needs a lot of work to run well on the phone.
