I use CalyxOS on my Fairphone since 2022. It is better than the stock OS and allows re-locking the bootloader. It also provides timelier updates than Fairphone OS. It is absolutely fine and has zero issues.
I have one banking app that doesn’t work. Another one that does work. Also, I have paid purchases through the Google Play Store that do not see the subscription. I was going to let them expire anyway. I also have a Google One that doesn’t see the subscription, so none of the advanced editing features in Photos works. I assume all of these would be problematic on GrapheneOS as well.
I would run GrapheneOS if I had a Pixel, or if it supported the Fairphone.
Honestly, fuck Bandcamp. I used that platform for years, purchased a huge library, supported artists even when I was about 90% sure that some of them were just resellers providing rips of the original artists music.
And then for no reason at all a few weeks ago, I was asked to verify my account via email. Despite using the correct autosaved password. That email never arrived. Never arrives no matter what I try. So I cannot get back in. Support is like check your spam folder like motherfucker you don’t think that’s the first place I went when I didn’t see the conformation email?
Fuck the new ownership. Fuck Bandcamp. Good luck with your upcoming job search.
