Disable KNOX Security on Galaxy S3/ S4/ Note 2/ Note 3

Rakesh | 20 Oct 2013 | Guides/ Samsung

Disable KNOX Security

The are various instances of exploits bringing out the security vulnerabilities of Samsung’s flagship Galaxy devices. To arouse the trust of business class customers, Samsung also launched an ad campaign. However, it was with the launch of the Galaxy S4 that the company introduced a dedicated security service trademarked as Samsung KNOX. Today, I’ll be telling you about the ways to disable KNOX security on the Samsung device like the Galaxy S3, Galaxy S4, Note 2, and Note 3.

Previously, the service was only available for people in enterprise and in government institutions. Later during IFA event in Berlin, Samsung showcased some new devices like the Note 3, Note 10.1 2014 Edition, Galaxy Gear and also revealed the commercial availability of its Knox mobile security system that helps better protect device data against unauthorized use.

What is Samsung KNOX?

In this way, if you have Knox installed on your device which you use asย personal and as a workplace phone both, Knox lets you store enterprise applications (corporate email, contacts, calendar, etc.) securely using an Exchange ActiveSync Server. The service is capable of separating personal and work data and thus it makes it possible for both types of data to coexist on a Knox-enabled device. You just have to press an icon to switch from personal to business mode. Here’s an official video that reveals what KNOX does:

Actually, Samsung came with KNOX when it realized that security-lovers and corporate class tended to abstain from its smartphones due to security vulnerabilities. By integrating KNOX in the TouchWiz UX, Samsung provided a second version of a smartphone as KNOX mode that is protected with a password and restricts unauthorized access. KNOX mode includes apps like Camera, Gallery, Downloads, Email, S Planner, My files, Phone, Contacts and S Browser by default. Besides these, there are about 75 KNOX-apps that you can download additionally.

Why Disable Samsung KNOX?

There’s no doubt that Samsung Knox service is really a good security solution for those who got a financial and business reason to protect their data, but there are still many others who might not like to have it on their device. If you are not a fan of the kind of security Knox provides and love to root your device and install custom ROMs on it without caring about the security warnings, we have come with some tips to disable Samsung Knox security shield on your device. Knox might also be responsible for FC (force close) error with some of your root perm apps, and so this is another sound reason to disable KNOX security on Samsung devices.

Unable to Get Root Access Due to KNOX?

If you have KNOX on your Galaxy device and you have rooted it, you’ll see a verification message that pops up every time SuperSU is called for action by some apps on your device. The message runs like this:

โ€œSuperSU tried to access system in your device without authorization. This action was blocked.”

OR

“An application attempted to access system on your device without authorization.”

OR

“Unauthorized access to a secured area has been blocked.”

You can get rid of this annoying thing easily by disabling Knox service and its agent apps. Remember, once KNOX is aware of SuperUser on your phone, it’ll block its functioning and you might not be able to use any root app. In case you are unable to get root access (after rooting your device) because KNOX prevents SuperSU in doing so, do this:

  1. Download the latest SuperSU zip package:ย UPDATE-SuperSU-vx.xx.zip
  2. Extract the zip and open the folder.disable knox security 2
  3. Go the folder named “common” and copy the Superuser.apk to your phone.
  4. Install the APK manually (do not forget to tick Unknown Sources option under Security settings of your device).
  5. Now launch the SuperSU app on your phone and it will ask youย whether or not you want to disable KNOX: “Samsung Knox has been detected. This might limit root capabilities and cause annoying popups. Try to disable KNOX.”
  6. Select OK. It will then tell you that KNOX has been successfully disabled.disable knox security

You should now be able to enjoy root access on your Samsung Galaxy device. If you want to remove KNOX from the device, use the method given below. If the above method does not work for you, your phone might not be rooted properly. Verify the root with Root Checker app. [googleplay url=”https://play.google.com/store/apps/details?id=com.jrummyapps.rootchecker”] If the root is not verified, root the device again and then try this method.

List of Galaxy Devices that Feature KNOX

Our tutorial on removing/ disabling/ uninstalling KNOX might be used to get rid of KNOX on all Samsung devices with Android 4.2 or above.ย The following Galaxy phones and tablets support Samsung KNOX:

  8. Now enter your KNOX password and then select Continue> Next.knox backup
  9. All backed up data that does not include your email and app data will be save as Zip to My Files> All> Knox.
  10. KNOX will then be uninstalled from your Samsung Galaxy device.

  5. Doing this will disable Samsung Knox on your device

Alternate Method To Disable KNOX

Uninstalling KNOX Apps on Rooted Devices

  1. Download and installย System App Remover app from the Google Play Store.[googleplay url=”https://play.google.com/store/apps/details?id=com.jumobile.manager.systemapp”]

Removing Samsung KNOX Using Root Explorer

If you have root privileges over your Samsung Galaxyย S3/S /Note 2/Note 3, there is yet another method using which you can get rid of this irritating KNOX thing.

  1. Install either Root Explorer or Root Browser app on your device:ย [googleplay url=”https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree”] [googleplay url=”https://play.google.com/store/apps/details?id=com.speedsoftware.explorer”]
  2. Now open Root Explorer/Browser and navigate to system/appย directory.
  3. Tap on the Search icon and type “knox”.
  4. Doing this will give you a list of KNOX and its related apps.
  5. Mark all item by checking the box and then tap on the Delete icon.uninstall-knox-security-apps
  6. Select Yes when you are asked if you want to delete the selected apps.

Having deleted these apps, there will still be some KNOX apps left on your phone. Let’s now eliminate them too. Go back to theย ย system/appย folder and find the following apps:

  • Container Agent.apk
  • Container Agent.odex
  • KLMSAgent.apk
  • KLMSAgent.odex

If you do not find KLMSAgent app in system/app directory, look for it in system/priv-app folder. Either mark these items together and delete them or find and remove them one by one.

    I contacted Samsung directly and they told me that if an incorrect password was entered 20 times, KNOX would be deleted. So I did that – and KNOX WAS FINALLY GONE ๐Ÿ™‚

    Hi,

    In what all ways can ‘current binary’ and ‘system status’ in Odin mode change to ‘custom’ ? I hav seen an unrooted note 2, having stock firmware, whose current binary and system status changed to custom and knox tripped. How can this be possible if its running stock firmware?

    • Nov 9, 2014 at 5:27 PM
      Rakesh says:
      Reply

      Flashing anything other than the stock firmware/kernel or recovery can trip the flash counter or KNOX Warranty void value. Today we had a comment where a user said TR tripped KNOX on his S4.
      However, I do suspect TR might have done that, save the fact Samsung might have done something that detects root exploits like TR and trip KNOX. I don’t think they would have done that because patching the exploit itself is what OEMs generally do.

        UPDATE-SuperSU-vx.xx.zip one. I had SuperSu from flashing CF root, but it still wouldn’t disable Knox and SuperSU kept Force closing. After installing this, it allowed me to disable it.
        I would maybe put in the notes that when you are ready to install the .apk it says at the bottom of the installer – NEW or ALL -. I chose New the first time and it wanted me to update the binary which then wouldn’t allow me to disable Knox, it just sat there spinning. I forced closed it and went back to install it and clicked ALL, which then popped up right way about disabling Knox which worked.

        Thanks.

      In that case, you should root the device to be able to access the system files for KNOX.

            After running the OTA update you now have knox on your device.. The only firmware you can flash is I9195XXUBMJ7 (knox secured).

            This still gives the issues with NFC though… the only way round it is to do with one file.. nfc_nci.MSM8960.so

Anyway im happy with this temporary solution and just will be waiting till the next 4.3 or 4.4 update and see if it will permanently fix the issue. Thanks dude!

      On some US variants, KNOX is interwoven in the bootloader and therefore it cannot be deleted unless you install a modified firmware.

    None of the above info helps me, nor any of the comments that say “just go to Knox….”. I have a new Galaxy S4 with Android 4.3, but Knox doesn’t show up anywhere in my apps, running services, or anywhere else I can find, except when I get one of those CONSTANT security warnings. Then and only then I can long press the warning, and it shows me the offending/reporting app is Knox. That’s the only time/way I can find it on my phone, and my only option is to stop the service, clear the cache, or clear the data. I’ve done all of the above to no avail, I still get the warnings.

    You can uninstall Knox. Press the “Knox” button, go to the homescreen (if it don’t happen automatically), press the “menu” touch button on your phone, press “Knox Settings”, and then press “About Knox”, aaaand “Uninstall”. I you have been using Knox actively you should make a backup, if not just press “uninstall” or something. ๐Ÿ™‚

      try, instead of one command, separating the ‘su’ and ‘pm …’ commands in terminal, like so (don’t type the $ or #, they indicate the prompt):

      (enter terminal emulator, grant root if not persistent)

      $su

      #pm disable com.sec.knox.seandroid

      #

      See if this does anything different for you. If not, try typing ‘which su’ to see which su command is being used… it might not be right due to search path issues.

        Actually, current Titanium Backup seems to be able to uninstall most of the Knox components on a properly rooted ROM (I’m using stock + the “Root de la Vega” method, which uses a su daemon spawned by init). What it doesn’t do, at least yet, is get around all of the SEAndroid restrictions which are really separate from Knox – not that Samsung makes the distinction. I think this may be tractable to some degree, but it’s still active development in that regard.

    I installed and opened Android Terminal Emulator and even though the device is rooted, there was no box asking for permissions.

    When I entered su pm disable com.sec.knox.seandroid, I got the following message as a notification:

    “An application attempted to access system on your device without authorisation. This attempt has been blocked. Deleting applications obtained from unauthorised sources may improve security.”

    The KNOX Disabler also did not work ๐Ÿ™

    i9505 running 4.3.
