Hello,
I'd like to start by saying that I really like your application.
It works very well on a Samsung S3 GT-I9300 running CyanogenMod CM11 (with root permissions for Boldbeast Call Recorder).
However, I've also got a Samsung Galaxy S2 GT-I9100T that's running CM12.1 + CM12.1 "stock" ROM and I'm unable to get Boldbeast Call Recorder v7.9 GP to record any calls.
I've Emailed you the logs from the same Email address I used to register to your forums.
I'd like to try and work towards a solution with you, besides resorting to install SELinuxModeChanger.
I'm not too comfortable installing an application that Google actively refuses to be featured on their store.
Regards,
