How can I contribute to the fairphone

I’d love that too and I believe Fairphone would love it aswell. But since they are a small team they can’t build the whole phone from scratch and depend on others.

But I allready told you: The first model Fairphone was a modification of a pre-existing phone and the manufacturors of the chipset don’t license their software and firmware openly. We allready know that with the new Fairphone the chipset manufacturor will be switched wich will definitly result in a more open source OS. But I have no idea if it will be fully FOSS.

For the new Fairphone they are looking for FOSS OS alternatives as you can read here. But for the current Phone I don’t think an official partnership with Cyanogen Mod is possible.
You can however install Cyanogen Mod 11 on your own.

No it definitly wasn’t. The Fairphone team didn’t expect that a partnership with mediatek would have such drastic downsides but unfortunately it did.
But you learn from mistakes and we all expect to see what Fairphone has learned with the new model.

I believe Github (the link I included) has such a bug tracking tool.
