Just in case anyone wants automatic call recording on Kitkat roms, or misses this feature from G2 tweakbox which does not work on kitkat at the moment,
I found a perfect call recorder that records from "voice_call" audio source which gives high quality recording as if you are hearing the call in your ears :D
This app is like another recorders such as "Call recorder", "Automatic call recorder", "Mp3 call recorder", but it's easier to use ,more lightweight and faster.
1# Record any phone call you want and choose which calls you want to save.
2# Set which calls are recorded and which are ignored.
