Directing user to set device PIN broken

[Phillrb]

There's a requirement in our product to have the user set a device PIN. Sadly, redirecting the user to the Android Set Device PIN screen is inconsistent and broken.   

In Android, you can test for device PIN / password using:

Quote

KeyguardManager keyguardManager = (KeyguardManager) unityActivityContext.getSystemService(Context.KEYGUARD_SERVICE);
bool isSet = keyguardManager.isKeyguardSecure();

You can then redirect the user to set a device PIN using:

Quote

Intent pinSetIntent = new Intent(DevicePolicyManager.ACTION_SET_NEW_PASSWORD);
pinSetIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
activity.startActivity(pinSetIntent);

We are experiencing the following issues:

• sometimes keyboard does not show to allow user to enter PIN
• sometimes a black screen is shown instead of the settings screen
• if user already has a device PIN set, PIN cannot be changed as there is a crash after entering the current PIN to authorize the change
• sometimes nothing happens at all

Can a member of VIVE support please:

1. confirm the recommended way for an app to enforce a device PIN be set?
2. confirm how to reliably redirect users to the 'Set device PIN' screen?

@HackPerception how is an app meant to direct or enforce the user set a device PIN? 

Are the standard Android APIs meant to be used or is there an alternative?

These are the steps a user can take to achieve it manually; but it'd be great if we could direct users there programmatically and check that the outcome is as required (PIN has been set):
