Why did my device display the notification, "Unable to Perform Automatic Update?"

All Samsung devices running the Knox framework.

Your device can automatically check for new security policy files every week. If you see this notice, you should perform a manual update to protect your device against the latest known threats. Make sure you have a network connection. Then tap Settings > General > Security > Check for updates.

If the update still fails, it may be due to:
  • A network connection error (try again later when you have a good data connection),
  • A device setting (if you have selected the Via Wi-Fi only setting to update the policy, make sure Wi-Fi is connected),
  • A device memory limitation (close all background apps or restart your device),
  • A policy file error (try again later).
