[AC Question]

I am creating an application were we record VOIP call using media recorder, other than Samsung device call get connected audio feed also received at both end and call get recorded with both audio and video. But when comes to Samsung device we are facing problem to record audio stream in recorded call. During our initial finding it was observed that Samsung device does not allow sharing of Mic when it is in use. We had tried with different audio source which are available

VOICE_CALL (not working)
MIC (not working)
VOICE_DOWNLINK (not working)
VOICE_UPLINK (not working)
DEFAULT (not working)
CAMCORDER (not working)
VOICE_COMMUNICATION (not working)
VOICE_RECOGNITION (not working)

I had also tried several call recording Audio/Video application some of them are listed below along with the test result

AZ Screen Recorder - Fail
SCR Screen Recorder - Fail
Screen Recorder 5+ - Fail
Background Video Recorder - Fail
Mobizen for Samsung - Fail

Is it possible to share mic in Samsung device when it is already consumed or mic is already in use by any other application ?
