How to disable View admin apps access when taking a screenshot

Environment

• Knox Manage
• Kiosk mode
• Android Enterprise

Overview

When attempting to capture a screenshot on a device applied with the Android Enterprise Screen Capture Permission policy set to Disallow, device users may notice a pop-up:

Can’t take screenshots because of the security policy. View admin apps

Clicking View admin apps opens the Device admin apps settings. When the device is in kiosk mode, this may cause an issue where device users are unintentionally granted access to the admin settings.

Cause

To prevent device users from accessing the Device admin apps settings, you must add the com.android.settings.DeviceAdminSettings component to the App Component Blocklist policy.

Resolution

To disable device user access to the Device admin apps settings:

1. In the Knox Manage console, go to Profile and select the profile policy you’d like to modify.
2. On the Set Policy page, go to Samsung Knox (Android Enterprise) > App Restrictions.
3. Under App Restrictions, set App Component Blocklist to Apply.
4. In the App List policy field, add the com.android.settings package.
5. Enter com.android.settings.DeviceAdminSettings to the Component field and click to add it to the App List.
6. Click Save or Save & Assign and push the profile to your device.

Device users can no longer access the Device admin apps settings once this policy is applied.
