How to restrict the Dynamic Wallpaper Service in Knox Manage

To restrict the Dynamic Wallpaper Service:

1. In the Knox Manage console, enable the Wallpaper File policy. This policy sets a custom wallpaper and changes the wallpaper service to None (non-dynamic wallpaper configuration).

2. Under App Execution Blocklist Setting, click Apply > Add > Add Control Application.

3. Add the following information:

   • Platform: Android
   • Package Name: com.samsung.android.dynamiclock
   • Application Name: Dynamic Lock Screen

4. Click Save.

5. Select Dynamic Lock Screen, then click OK.

6. Save and apply the profile to your devices.

After the profile is applied, device users can no longer override the custom wallpaper by setting a dynamic lock screen.
