Describe the bug

FaceLivenessDetector just shows black screen as it seems like it cannot access Camera using camerax library due to following permission error on Sony Xperia XZ3

Access denied finding property "persist.vendor.camera.privapp.list"

CAMERAX VERSION - 1.4.0-beta02 OS VERSION - ANDROID 10 DEVICE NAME: Sony Xperia XZ3

Reproduction steps (if applicable)

Try to render any @Composable screen that contains com.amplifyframework.ui.liveness.ui.FaceLivenessDetector on Sony Xperia XZ3 phone.

Code Snippet

FaceLivenessDetector(
  sessionId = uiState.sessionId.value,
  region = uiState.region,
  credentialsProvider = uiState.credentials,

    onComplete(uiState.sessionId)
  },
  onError = onError,
)

Suggestions on any work arounds would also be appreciated.

@shakil-bin-karim Can you please try and restart the device. I know that is a strange ask, but sometimes the Android camera gets in a weird state and fails to launch properly. The Camara has some shared state elements that make an app restart not enough.

If that doesn't work, can you try with 1.2.0 as is included in the Liveness library. There could be bugs with the beta library of CameraX you are using.

If neither of these suggestions work, please provide additional logs. I wouldn't expect the logcat to end there.
