Yeah… With latest Tytung r9 beta kernel, you can record phone call conversation now (2-way in call recording). Currently, there are 3 NAND Android ROMs that I tried which is using Tytung r9 beta kernel. And I managed to record my calls with BOYPPC-SHIFTPDA GINGER HoneyComB. Besides Tytung r9 beta kernel, all you need is a call recorder application by XDA Developer, skvalex.
