How to remove Knox from Samsung depends on what you mean by “Knox.” If you are seeing a work profile, Knox Manage enrollment, Knox Guard restriction, or another management screen, you usually need to remove the specific management service rather than Knox itself. Samsung Knox is built into the security architecture of supported Galaxy devices, so it is not normally something you can uninstall like a regular app. The right solution is to identify which Knox service is active and then use the proper removal or unenrollment process.
This is especially important if you bought a used Samsung phone, left a company, completed a device-financing agreement, or suddenly noticed work-related apps on your personal phone. A factory reset may erase your personal information, but it does not necessarily remove a device from an organization’s server-side enrollment system.
Samsung provides separate management systems for different situations, so the first step is figuring out what you are actually seeing on the phone.
What Is Samsung Knox?
Samsung Knox is a collection of security and device-management technologies used on compatible Samsung devices. Businesses, schools, retailers, carriers, and other organizations can use Knox to protect information and manage company devices.
That means “Knox” can refer to several different things, including:
- Knox Manage: Used by organizations to manage Samsung devices.
- Knox Mobile Enrollment: Can automatically enroll a device into an organization’s management system during setup.
- Knox Guard: Used by carriers, retailers, and financing partners to manage or restrict certain devices.
- Work Profile: Separates work applications and data from personal information.
- Knox security features: Built into supported Samsung devices and not normally removable.
Because these services work differently, there is no single “remove Knox” button that fixes every situation.
For background on Samsung’s enterprise security and management platform, you can also refer to the official Samsung Knox documentation.
Can You Completely Remove Knox from a Samsung Phone?
Usually, you cannot remove the underlying Samsung Knox security platform. It is part of the device’s security architecture rather than an ordinary application.
However, you may be able to remove a Work Profile or have a company, carrier, retailer, or financing provider unenroll the phone from its management system.
| What you see | What it may mean | What to do |
|---|---|---|
| Work apps with briefcase icons | Android Work Profile | Remove the Work Profile if you are authorized |
| Company management message | Knox Manage or another MDM service | Ask the organization to unenroll the phone |
| Company setup returns after reset | Possible Knox Mobile Enrollment | Have the organization remove the device from enrollment |
| Financing or payment restriction | Possible Knox Guard management | Contact the financing provider, retailer, or carrier |
| Knox WARRANTY VOID: 0x01 | Knox Warranty Bit has been tripped | A normal factory reset will not reverse it |
1. Check for a Samsung Work Profile
If you see apps with a small briefcase icon or a separate Work section on your Samsung phone, you may simply have an Android Work Profile.
A Work Profile keeps work applications and information separate from your personal data. If the phone is personally owned and the organization no longer controls it, you may be able to remove the profile through Settings.
Depending on your Samsung model and Android version, look under:
Settings > Passwords and accounts > Work
or search Settings for Work Profile.
If you see Remove Work Profile, follow the instructions on screen.
Keep in mind that removing the profile also removes its work applications and locally stored work data. If you need those files, check with the organization before removing it.
2. If Knox Manage Is Controlling the Phone
Knox Manage allows an organization to manage Samsung devices. Samsung’s current documentation says that administrators can unenroll devices from Knox Manage, and depending on the device configuration, they can remove only the Work Profile or perform a factory reset during unenrollment.
You can see Samsung’s current process in its Knox Manage device unenrollment guide.
If you bought a used Samsung phone and it still displays a company management message, the previous owner may not have removed the phone from the organization’s management system.
What to do:
- Contact the organization that previously managed the phone.
- Ask its IT administrator to unenroll the device from Knox Manage.
- If you purchased it used, contact the seller and request that they arrange the release.
- After the release is confirmed, reset the phone if necessary.
Repeatedly resetting the phone will not necessarily solve a server-side enrollment problem.
3. Check Knox Mobile Enrollment
Knox Mobile Enrollment, or KME, can automatically enroll Samsung devices into an organization’s management system during setup.
This explains why a phone can appear to be completely reset but then return to a company setup screen when you connect it to the internet.
Samsung’s documentation explains that administrators can unassign KME profiles and, when appropriate, delete devices from Knox Mobile Enrollment. The change can then be applied when the device connects to the internet.
See the official Samsung Knox Mobile Enrollment documentation for the administrator-side process.
For example, imagine buying a used Galaxy phone. You perform a factory reset and start the setup process. Instead of getting the normal Samsung setup screen, the phone asks you to contact an organization.
The reset may have worked correctly. The device may simply still be registered with the previous organization’s Knox Mobile Enrollment account.
In this situation, the organization needs to remove the device from its enrollment records. A reset performed by the new owner usually cannot replace that server-side action.
4. What If Knox Guard Is Restricting the Phone?
Knox Guard is different from a normal Work Profile. It can be used by organizations such as carriers, retailers, and financing partners to manage certain devices.
If a Samsung phone displays a financing, payment, or management restriction, do not treat it like an ordinary application that can be deleted.
Samsung’s current Knox Guard documentation explains that when a device is no longer needed under Knox Guard management, it can be removed from the service through the authorized management process.
Try this:
- If the phone is financed, contact the financing provider.
- If it came from a carrier, contact the carrier.
- If you bought it from a retailer, ask the retailer to confirm its management status.
- If you bought it used, ask the seller to have the original provider release the device.
You can read more in Samsung’s official Knox Guard documentation.
5. Check Device Administrator Settings
Some management applications have device-administrator privileges. On Samsung phones, search Settings for Device admin apps, Device administrators, or Security.
The exact menu depends on your One UI and Android version.
If you recognize an old work-management application and the phone is personally yours, check whether its administrator access can be removed before uninstalling it.
Do not disable security software simply because you do not recognize the name. A company-owned phone may have administrator controls that are intentionally protected from user removal.
6. What If You Bought the Samsung Phone Used?
This is one of the situations where people most often search for how to remove Knox from Samsung.
Suppose you buy a Galaxy phone from an online marketplace. The seller says it has been reset, but during setup you see a company name or a message telling you to contact an administrator.
That is a sign that the phone may still be associated with an organization.
What to do:
- Take a photo of the management message.
- Write down the phone model and serial information.
- Contact the seller.
- Ask whether the phone was previously used by a company, school, carrier, or financing provider.
- Ask the seller to have the original organization release the device.
- Keep your receipt and transaction information.
If the seller refuses or cannot provide a legitimate release, consider using the marketplace’s buyer-protection process instead of paying an unknown service to bypass the management system.
7. Should You Factory Reset the Phone?
A factory reset can be useful, but it should not automatically be your first step.
Resetting the phone removes personal information, applications, settings, and other locally stored data. However, it does not necessarily remove a device from an organization’s Knox enrollment records.
Before resetting:
- Identify the Knox service involved.
- Back up your personal information.
- Ask the authorized administrator to release the phone if necessary.
- Remove the Work Profile if appropriate.
- Perform a factory reset only when it is part of the legitimate removal process or when you are preparing the phone for a new owner.

8. Do Not Confuse Knox With Secure Folder
Samsung’s Secure Folder uses Knox security technology to protect apps and personal information. Seeing the word Knox does not mean that Secure Folder itself is a Knox management system.
If you simply want to stop using Secure Folder, remove Secure Folder through its own settings rather than attempting to modify the phone’s security architecture.
Likewise, if your concern is storage rather than device management, changing Knox is unnecessary. Our guide on how to clear phone storage covers safer ways to free up space.
9. What Does Knox WARRANTY VOID: 0x01 Mean?
If you see Knox WARRANTY VOID: 0x01, you are dealing with something very different from a Work Profile.
The Knox Warranty Bit is a hardware-backed security state associated with certain Samsung security features. It can be affected by unauthorized modifications to the device software.
This is not the same thing as having a Work Profile or Knox Manage enrollment, so deleting an app or performing a normal factory reset is not a way to restore that state.
If you believe the Warranty Bit has been affected and Samsung services are no longer working correctly, use Samsung Support or an authorized service provider.
10. Should You Root or Flash the Phone to Remove Knox?
If your goal is simply to remove an old work profile or company enrollment, modifying the phone’s operating system is unnecessary and can create additional problems.
For a personally owned phone with an old Work Profile, use the normal profile-removal process. For a company-managed or financed phone, have the authorized organization release it.
Avoid websites that ask you to install unknown APK files, provide your Samsung account password, give remote access to your phone, or pay for an unexplained “Knox bypass.”
11. What If Knox Manage Will Not Unenroll?
Sometimes an administrator attempts to remove a device but another management component prevents the process from completing.
Samsung’s documentation notes that certain device-management configurations can prevent normal unenrollment. In some cases, service intervention may be required.
What to do:
- Ask the administrator which Knox services are active.
- Check whether Knox Manage, Knox Mobile Enrollment, or another management service is involved.
- Have the administrator remove the device from the relevant management system.
- If normal unenrollment fails, contact Samsung or an authorized service center.
12. Example: Removing Knox After Leaving a Company
Imagine that you used your personal Samsung Galaxy phone for work. Your employer installed a Work Profile and managed it through Knox.
After leaving the company, the phone still shows work applications and restrictions.
The clean solution is for the organization to release the device from its management system first. Once that is done, remove the Work Profile from your phone and confirm that the company applications and policies are gone.
If necessary, back up your personal information and perform a factory reset before setting the phone up again.
13. How to Tell Which Knox Problem You Have
| What you see | Likely cause | Best next step |
|---|---|---|
| Briefcase icons on work apps | Work Profile | Remove the Work Profile if authorized |
| Company management message | Knox Manage or another MDM | Ask the organization to unenroll the phone |
| Company setup returns after reset | Knox Mobile Enrollment | Have the organization remove the device from enrollment |
| Financing-related restriction | Knox Guard | Contact the financing provider, carrier, or retailer |
| Knox WARRANTY VOID: 0x01 | Knox Warranty Bit | A factory reset will not solve the underlying issue |

When Should You Contact Samsung?
Contact Samsung or an authorized service provider when the problem goes beyond a normal Work Profile or management enrollment.
This is especially appropriate when:
- The Knox Warranty Bit appears to be affected.
- The phone cannot complete setup.
- The device remains managed after authorized unenrollment.
- A persistent management error appears.
- You need model-specific service instructions.
For the most accurate information, use Samsung’s official support resources because the exact process depends on the service managing the device.
Frequently Asked Questions About How to Remove Knox from Samsung
Can I uninstall Samsung Knox like a normal app?
Not generally. Samsung Knox includes security technologies built into supported devices. However, specific management services or a Work Profile can sometimes be removed through authorized procedures.
How do I remove Knox Manage from my Samsung phone?
If the phone is enrolled in Knox Manage, the normal solution is for the authorized administrator to unenroll it. Samsung provides an official Knox Manage unenrollment guide for administrators.
Can I remove Knox after leaving my company?
Yes, if the phone is yours and the organization has released it. The company may need to remove the device from Knox Manage and Knox Mobile Enrollment before you can completely remove the work environment.
Can a factory reset remove Knox?
A factory reset removes personal data and settings, but it does not remove Samsung’s underlying Knox security platform. It also may not remove a phone from an organization’s server-side enrollment.
Can I remove Knox Guard myself?
If Knox Guard is managing the phone, contact the carrier, retailer, financing provider, or other organization responsible for the enrollment. They may need to complete or release the device.
Does removing a Work Profile remove Knox?
No. Removing a Work Profile removes the work applications and data associated with that profile. Samsung’s underlying Knox security technologies remain part of the supported device.
What does Knox WARRANTY VOID 0x01 mean?
It indicates a Knox Warranty Bit state rather than an ordinary app or Work Profile. A normal factory reset is not a way to reverse it.
Why does Knox come back after I reset my Samsung phone?
The phone may still be registered with an organization’s Knox Mobile Enrollment or another management system. A factory reset can return the device to the setup process without removing the organization’s server-side enrollment.
Quick Checklist On How to Remove Knox from Samsung
- Check whether you see a Work Profile or briefcase icons.
- Look for a company management message.
- Determine whether Knox Manage is involved.
- Check whether the phone may be enrolled in Knox Mobile Enrollment.
- If the phone is financed, contact the financing provider or retailer.
- Ask the previous organization to release a used company device.
- Remove a Work Profile only when you are authorized to do so.
- Back up your personal information before a factory reset.
- Do not expect a factory reset to reverse a Knox Warranty Bit state.
- Avoid unofficial Knox-bypass applications and firmware.
- Contact Samsung or an authorized service provider when necessary.
Final Thoughts On How to Remove Knox from Samsung
When looking for how to remove Knox from Samsung, the most important step is identifying which Knox feature you are dealing with. A Work Profile, Knox Manage enrollment, Knox Mobile Enrollment, Knox Guard, and the Knox Warranty Bit are different systems and cannot all be removed in the same way.
If it is simply an old Work Profile on your personal phone, removing the profile may solve the problem. If the phone is still registered with a company, carrier, retailer, or financing provider, that organization usually needs to release it first.
Do not try to remove Samsung’s underlying security architecture with unofficial software. A factory reset will not solve every Knox-related problem, particularly when the device is still enrolled with an organization.
The safest approach is simple: identify the Knox service, confirm who controls it, back up your information, use the official removal or unenrollment process, and contact Samsung when the problem requires professional support.
