Ask HN: With the death of Cyanogen, what options exist for a Free phone?
Cyanogen OS was not free, neither was CyanogenMod.
The Fairphone 2 has an official, monthly updated system that is mostly (beside firmware and other Qualcomm shit) free software. You can install it optionally, search for Fairphone Open OS.
Thanks for the reference.
LineageOs is the replacement for cycnogen,
