OnePlus 5无法通过音频管理器在通话模式下启动扬声器

我试图在通话模式下将设备音频设置为扬声器。
它在我检查的大多数设备上工作。OnePlus 5无法通过音频管理器在通话模式下启动扬声器

我购买了OnePlus5设备，但没有使用它。

final AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE); 
audioManager.stopBluetoothSco(); 
audioManager.setBluetoothScoOn(false); 
audioManager.setSpeakerphoneOn(true);

当我检查的结果是假的：

audioManager.isSpeakerphoneOn() // return false

，我可以在logcat中看到，当我从原生拨号器，他们是用一些不同的对象设置扬声器设置扬声器：
