I want to install a working call recording application on Galaxy S3, but I have found problems with a few apps.
I have tried Auto Call Recorder but it doesn't allow me selecting more than Mic as audio source. Perhaps I can record only my own voice (I haven't tried further and I obviously haven't bought the full program)
I have previously tried Call Recorder Pro but it only recorded my own voice and not the other party's.
I have read here that most call recorder apps require root (OK for me) and Requires the kernel with 2-way call recording patch
The question is, then
How do I make a call recorder fully work on a Galaxy S3 (GT-I9300) with only root for now? Do I need to flash a custom firmware? Or won't it just work at all?
