I'm trying the trial version in a galaxy s2 I9100 with the XWLP7 stock rom and a modified version of Speedmod kernel.
I have installed the 2-way record libraries from the option that appears just when I opened CallRecorder for the first time.
I've selected in preferences:
Device: Samsung Galaxy S2 (Android 4 ICS)
Record calls from: Android Standard API
Standard API Preferences:
...Audio source: Voice uplink
...Action on BT connected: Switch audio Source
...Audio source when there are BT: Voice Downlink
And each time I try to do a call I only can see a black screen except the top bar, I can hear how the call is being performed but I cannot finish it or do anything and after some seconds a message to force close the callrecorder aplication.
What I'm doing wrong?
