Users aren't prompted for fingerprint identity for managed apps on Samsung Note 4

This article describes a fingerprint authentication issue when using Microsoft Intune policy-managed apps on Samsung Galaxy Note 4 devices.

Symptoms

You have Intune app protection policies configured for some apps on Android devices. Although the Allow fingerprint instead of PIN (Android 6.0+) policy setting is set to Yes, users are not prompted for fingerprint authentication when using the targeted apps.

This issue is typically seen with Samsung Galaxy Note 4 devices, but the issue can affect other devices as well.

Cause

Samsung Galaxy Note 4 devices use a Samsung proprietary fingerprint management API that isn't supported by Intune.

Workaround

To work around the issue, use an alternate device that supports a fingerprint management API that is supported by Intune.
