I have written a simple app that records and plays audio through a Bluetooth Mono headset usingstartBluetoothSco(). The app works fine on Gingerbread but fails to work on ICS. The output of logcat is strange

It keeps calling the Native read from socket function till the app (sco connection) is terminated . It's worth mentioning that  tried tha app on Samsung Galaxy Mini(Gingerbread) , HTC (Gingerbread) , pandaboard(ICS) and ODROID-X(ICS).

Any suggestions for why the app stucks and readNative is being repeatably called ?
