I am essentially in the same boat, running CyanogenMod stable as well, mostly to escape google. I am having many issues with it, and have been actively looking for a good alternative. There are a few open source phone projects ongoing, but non are in production yet so for the time being Replicant seems to be better than CyanogenMod to me, but it has limited hardware support at the moment. I do think your S2 is supported though, you might try it out. http://www.replicant.us/ http://www.replicant.us/ And for anyone wondering about privacy/FOSS tools in general, the EFF put together Prism-Break site has been constantly updated. https://prism-break.org/en/all/ https://prism-break.org/en/all/
