hy 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 it.

Unable to Get Root Access While Being Rooted?

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:

“SuperSU tried to access system in your device without authorization. This action was blocked.”

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

“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:

Download the latest SuperSU zip package: UPDATE-SuperSU-vx.xx.zip
Extract the zip and open the folder.
Go the folder named “common” and copy the Superuser.apk to your phone.
Install the APK manually (do not forget to tick Unknown Sources option under Security settings of your device).
Now launch the SuperSU app on your phone and it will ask you whether or not you want to disable KNOX.
Select OK. It will then tell you that KNOX has been successfully disabled.

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.
