Whether you purchased a used Samsung phone or got one from your organization, you may see the warning “This phone is protected by Knox cloud service” when setting it up. Although this security feature benefits any organization by streamlining the initial setup and device enrollment, it is annoying if you want to unlock it for personal use, even after a factory reset, especially when you don’t know how to remove the Knox Enrollment service.

To facilitate you, this article features two efficient Knox Cloud service unlock solutions. But first, let’s look at the Samsung Knox Enrollment service.

Part 1: Why Does Your Samsung Phone Say Protected by Knox Cloud Service?

The message “Your phone is protected by Knox Cloud Service” means that your device is enrolled on Knox enrollment service.

This Samsung Knox Mobile Enrollment service helps businesses to seamlessly and quickly set up and handle the bulk of Samsung phones with low configuration variation without manual intervention, thus ensuring security, compliance, and efficient device management. This is done by the authorized resellers or the IT administrators who configure profiles.

However, in some cases, users inquire if it’s possible to remove the Knox Enrollment service for certain activities, like getting root access, customizing OS, and more. The answer is yes. However, remember that this should not be done without your employer’s consent.

Part 2: How to Fix “This Phone Is Protected by Knox Cloud Service”?

Once you have learned about this security feature by Samsung, it’s time to delve into the leading Knox Cloud service unlock methods. Let’s discuss them one by one with the detailed tutorials:

Method 1. Remove Knox Enrollment Service from the Admin Account

The Knox Enrollment service is beneficial for IT administrators because the users can’t delete the KME app from their Samsung phones to mishandle them. However, this is possible only with the Samsung Knox portal. Here is a step-by-step guide on how to remove the Knox Enrollment service from the admin account:

Step 1. After opening the Samsung Knox portal, sign in using the admin credentials.

Step 2. Now, choose “Samsung Knox Mobile Enrollment” and click “Devices.”

Step 3. It’s time to select your Samsung phone and press the “Actions” button.

Step 4. Tapping the “Clear Profile” button will remove the profiles on your device.

Step 5. However, if you pick the “Delete Device” tab, the Knox Enrollment service is disabled.

Sometimes, you even need to uninstall the Knox app from the Samsung phone by opening “Settings”> “Apps”> “Knox”> “Uninstall” or “Disable.” This option is not available for all devices based on the Knox configuration.

Method 2. Remove Knox Enrollment Service without Password

If you can’t access the admin account password, especially when you purchased an employee’s phone, this method is the only way out. Although this is a little tricky and a long process with the requirement to download a third-party tool, you can try it to access your device without a password. Let’s comply with the given tutorial on how to remove the Knox enrollment service without a password:

Step 1. Once you see the login screen, click the back button two times and choose “Yes.” You will see the enrollment in progress loader. Press the return icon again and tap “Wipe.”
