I am Facing problem with whatsApp during audio calls using Bluetooth headsets and Samsung Phone.
During audio/video class using Whatsapp, I am able to listen everything properly but the the listner on the other side, is not able to hear the sound properly. I have tried with multiple Bluetooth ear-pieces.
The problem happens only with Whatsapp Calling. However If I call using Google Hangout, or facebook call, I do not experience any such problem.
