Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
have you tried it on a real device? maybe this is a hardware support issue, but no matter which DE i use (be it phosh, plasma mobile, gnome, …) it was extremely buggy and mostly unusable. battery drained like crazy, calls didn’t work properly, the list goes on. to be fair this was on a poco f1 and lg k10, which aren’t in main or community though…
my daily driver is a 2013 phone with custom rom and i’ve daily’ed a self ported ubports phone in the past, my level of tolerance for buggy experience in daily driver phones is very likely much lower than others
Yeah, device support is the biggest issue. But the OS as a whole is pretty good. I used it with a OnePlus 6T and a Nothing Phone 1, both of which have pretty decent support. Some things about it were broken, and I didn’t try putting in a SIM card and making calls or texts, but the overall experience was good. I have high hopes for when we eventually get good “flagship” linux mobile phones that have full PostmarketOS compatibility.
