You are calling unregisterReceiver(wReceiver); in onPause(). This means that every time that the Activity goes into the background (including when the screen turns off), your Activity is unregistered for that broadcast.

onPause() is likely getting called before your Activity gets a chance to receive the Broadcast.

Perhaps you want to place unregisterReceiver(wReceiver); in onDestroy() instead?
