Still looks like a hobbyist project that, depending on your device, is pretty far from anybody's daily driver? I do toy with the idea of running Linux on my phone, but UBports is sliding still further down my list of candidates whereas PostmarketOS feels more mature.
I got really close to daily driving it. I had most of the stuff I wanted in waydroid on a pixel 3a. I just need to get the android notifications bridged out from android to dbus to postal and I'd make the switch
I can't quite remember the GPS situation. I believe I had something working, but I think it might have been something from the UT store, uNav. However I can't speak to GMaps since I do my best to avoid Google apps.
In 2023, after the 2022 Ubuntu LTS was released, Ubuntu Touch finally upgraded from the 2016 LTS... to the 2020 LTS. Which they're still on today.
They've announced they're finally going to get their shit together and be based on recent releases of things after Ubuntu 24.04 is released later this year. Personally, I wouldn't recommend trying it before they do that.
