I used it for a few years on Oneplus Nord, and a few days ago switched to pixel7 with LineageOS. First impressions are that e/os was much more usable out of the box.

I surely have worse experience with banking: Revolut and SmartID app just refuse to work due to rooted phone (worked well on e/os). Other bank app is somewhat more broken - on e/os it didnt fully load but at least showed notificatioms on each transaction, now doesnt and is useless.
Could be due to newer android version on LineageOS though, I didnt investigate that.

/e/ has good but not perfect privacy. It still contains connections to Google and they added a tracking parameter to their update calls.

Their update cycles are very slow. You are usually one to two months behind monthly security updates. Full bulletins are a year behind and Webview is a problem as well. They ignore this point and do not realize, that Insuffizienz security is a privacy risk AS well.

So if you want good privacy with a convenient user experience and without thoughts about security, here you go.

Im using it for a couple of years. I flashed my fairphone 3 by my self back then, before the easy installer. It was the first time i did something "advanced" with a phone, but it worked quite well. After my fairphone 3 died, I bought a Fairphone 4 via murena. So everything was already installed etc In total I am happy with the Os. Their goal, the release of privacy oriented OS for everyone (so f.e. even my parents could use them) is quite of a utopia I suppose. But still, the team and community are doing a good job.

Yeah I already heard about grapheneOS, but its not working well with fairphone right? So murena it is for me :) And I would recommend to people, who are aware of the downsides and are little enthusiastic :)
