我BiometricPrompt在我的应用程序中使用 Android P (API 28) 中的新 API。（我实际上是在基于这个项目的包装器中使用它，以便它也可以在旧设备上运行，但这与问题无关。）这在我测试过的所有设备上都运行良好，三星 S9 除外人脸解锁。
尽管BiometricPrompt当前的 Android 版本仅支持指纹认证，但三星似乎已将其扩展为支持人脸解锁。当我在我的应用程序中触发生物识别身份验证时，“底部工作表”会弹出一个面部图标（而不是所有其他设备上显示的指纹图标），并且在屏幕顶部会出现一些文字，上面写着“未检测到面部”。（注意这里显示的图标是操作系统提供的，不是我的，所以很明显是三星设计的。）
根据文档，只有在身份验证成功BiometricPrompt时才应该关闭自己并调用我的方法。onAuthenticationSucceeded根据logcat，看起来它已经成功了：

根据文档，生物特征认证的成功应该已经解锁了密钥库，但这显然没有发生，如Key user not authenticated异常中的消息所示。
我怎样才能得到这个工作？
