Samsung KNOX was made to enhance the protection of the Android system and your data in general. Starting with version Android 4.3, the Korean giant began adding this program to the firmware of its smartphones and tablets by default. This has become an excellent solution in business, where the first priority is not ease of use, but the safety and security of your personal information.
But this began to cause problems for ordinary users, especially if you received ROOT rights. You've probably encountered the error:
“The SuperSU app tried to access the system item on your device without permission. This attempt has been blocked. To improve security, you can remove applications downloaded from unauthorized sources.”
At the same time, you do not fully have root rights, since they are blocked. But this problem can be solved by removing or disabling Samsung KNOX. There are 5 ways to do this.
Method No. 1: For users without root rights
- 1. Find the KNOX utility in the list of applications and launch it.
- 2. Press the menu button and select “KNOX Settings”
- 3. Select “Remove KNOX”
- 4. When the uninstallation process asks you if you want to back up your Knox data, click “Back up now.”
- 5. If they ask for your password, enter it.
- 6. Click “Next” and then the “OK” button.
Now you have gotten rid of the annoying defender.
This instruction is suitable for smartphones with stock firmware without root rights. If you have them, then the other 4 methods will suit you.
How to turn it on
If you are using a Samsung gadget based on the Android operating system, but do not notice the program is working, but would like to use it, then follow the following activation algorithm:
- Go to the device settings and management policies window,

The utility works with all popular smartphones: Samsung Galaxy S5, Galaxy S4 (Mini and regular versions), Note, Mega and tablets: Note 10.1 (2014). Tab S. And this is not a complete list of devices. This can also be done using the terminal.
Common errors and their solutions
The Samsung Knox app may experience intermittent problems.
The most common errors reported by users are:
- conflicts with applications running with root rights. In order to protect the OS from outside interference, Knox blocks access to such applications to the device hardware. There is no way around this limitation. The only solution is to disable or uninstall Knox;
- It is impossible to create a protected folder. This problem occurs on devices to which custom firmware was applied or superuser rights were obtained. Samsung cannot guarantee that Knox will work correctly on upgraded devices, so it prohibits the creation of a container. The solution to this problem is to replace the hardware and the printed circuit assembly;
- Samsung Pay stopped working. The payment service is blocked after the Knox counter is triggered. You can restore its operation only by deleting the Samsung Knox application.
If, when purchasing a Samsung device, the packaging contains the inscription “Is protected by KNOX,” then the owner of the device can be confident in the reliable protection of his data from access by third parties. However, it should be remembered that stable operation of the KNOX application is only possible when using official firmware. Any unauthorized intervention in the system can lead to malfunctions of not only the program itself, but also the mobile device.
Samsung has rightfully gained popularity among customers with its high-quality products.
Mobile phones are no exception in this case. those who have already become the owner of a Samsung smartphone may have encountered an unfamiliar application, which is KNOX.
In this regard, a completely reasonable question could arise: Samsung KNOX what is it?

Application operation
During its launch, the operating system kernel is checked for unauthorized access.
In fact, the presence of such a shell completely eliminates the possibility of unauthorized persons making changes to the OS on the subject.
In fact, this is what happens.
However, with an overall positive trend, a drawback should also be mentioned, even if it is not significant.
When the KNOX program is installed on a smartphone, root access to the device does not work correctly.
However, not every owner of a Samsung mobile device needs to obtain these rights.
After the kernel check is completed, the Knox program will monitor automatically launched applications.
This will forcefully terminate the activity of those that do not have user permission to run in the background.
Any application located inside a secure shell is fully managed and monitored for exceeding the existing access level.
This feature prevents one or another program from gaining access to functions that do not correspond to it.
The security of corporate data from unauthorized copying is built on (virtual private networks) at a time when home and public networks still remain unprotected.

Samsung Knox: what is it and how does it work
Samsung Corporation has developed a special Knox platform, implemented as a software and hardware add-on for Android. Its goal is to protect user data by isolating it from general information in a secure environment, the so-called KNOX container, which can be compared to a safe. In this “safe” the user can place both applications and any personal information that he deems necessary to hide from prying eyes. Access to a closed area occurs using a separate password, pattern key or fingerprint, so if the device is stolen or lost, the person who finds it will not be able to see the “secret” information.
Knox is a multi-layered platform for implementing secure space, built into Samsung devices at the hardware and software levels
On one device, a user can have 2 identical applications: one in an open area (for example, Viber for personal correspondence), and the second in a protected area (Viber for business contacts). This is especially true for employees of organizations that support the BYOD (bring your own device) concept. Its essence is that employees are allowed to use personal devices (laptops, tablets and smartphones) for work. Thanks to Knox technology, personal and corporate data is securely stored on the device at different levels.
Knox allows you to create two areas and two home screens on one device to isolate personal and corporate data
In addition to providing the user with encrypted storage, Samsung Knox monitors the integrity of all device systems, checks automatically launched applications, securely boots the operating system, protects against spyware and viruses, and allows you to remotely detect a lost device, block it, or delete your data. Unlike antivirus programs, Knox does not detect and remove malware; it simply prevents them from entering the device’s OS.

Causes of burning
Let's try to figure out why there is a burning sensation in the stomach. This can be difficult to do. It’s not always the fault of simple overeating or fatty foods.
After meals
A burning sensation in the stomach after eating most often occurs either due to junk food or due to improper consumption. And even more so if there are predisposing factors, for example, a damaged mucous membrane. Food has an irritating effect on sensitive nerve endings, causing inflammation and a burning sensation.
The reasons may be different:
Spicy, fried, salted, fatty, smoked, pickled. Such foods may contain carcinogens, trans fats, various toxins, acids and other irritants. Rough food. Due to the large amount of fiber it contains, it causes mechanical irritation, like sandpaper. As a rule, these are fruits, vegetables, and bran bread. Citrus fruits, pineapples, other sour fruits, including due to the high content of ascorbic and other acids. Dairy products with high acidity. Alcohol of any strength
It doesn’t matter what, be it wine, beer or all kinds of cocktails. Prolonged fasting.
What to do if you need to hide personal videos or photos
As surprising as it may sound, this directory is also suitable for the user’s personal purposes. For example, if you need to move important pictures or screenshots, or other objects from the main gallery, you need to follow a few simple steps:
- Go to the main Gallery folder on your device.
- Select any photo, then find the “three vertical dots” tool at the bottom of the screen.
- Click on it and tap on “Move to Knox Folder”. After this, all selected content is transferred to secure storage.
- To make sure that the file went there, enter the hidden directory and enter the password that you set for it. All the content you just marked will appear there.
- Next, if you plan to hide this folder, go back to Settings, then find this directory and move the slider to the Off position.
Proven Security
The Samsung Knox platform is approved by cybersecurity experts around the world. It has received more certifications from government agencies than other similar solutions.
Smartphones, tablets and other devices that integrate Samsung Knox have been certified by 32 national security agencies. In particular, the decision was approved by the National Security Systems Agencies of France, Finland and Korea.
An independent study conducted by Gartner in May 2022 also showed the high level of the Samsung Knox platform. It received a strong rating in 27 of 30 rating categories.
What were the problems with Knox?
Applications that run outside of Knox's influence have limited access to stored data. While many people wouldn't question this information, many developers have a different opinion, including Chainfire, which created the popular TriangleAway app designed to reset your device's flash counter, and SuperSU.
The problem is that Knox's security prevents access to multiple apps when you root your device, and can cause issues with your warranty since modifications to your phone will disable the flash counter (and prevent it from resetting to zero).
Applications outside of Knox's reach have less access to stored data.
The reason that is controversial is that Knox works with eFUSE (auto-configuration technology) used to track when a device has been modified. This means that Samsung could use Knox data to deny user support requests during the warranty period, as this would indicate that the device was damaged by the user.
Samsung has already included a counter in the bootloader that tracks how many times you've modified the OS. The problem is that applications running outside of Knox have limited access to stored data, and therefore applications developed by the modding community are negatively impacted.
Why create a protected folder on Android
In life, things often happen in such a way that you need to hand over your device to strangers. It can be quite difficult to influence the situation, since this happens at airports and customs. Refusal to show your phone can result in a person not being allowed to cross the border or onto a plane. But what to do if you don’t want to show personal information even to a person during execution.
You can hide the contents of your device from prying eyes using a password. Once you install it, you won’t have to worry about transferring your phone into the wrong hands. You just need to know how to put a password on a folder on your Android phone to protect important data without losing it.
Is it possible to password-protect a folder on Android without third-party programs?
How to hide a folder on Android - all the ways to hide files
Data protection is an important task. But many consumers need to do it quickly. Therefore, they need to know whether it is possible to password protect data without third-party programs. Some Galaxy, Huawei, Redmi, Xiaomi, ZTE, and Samsung smartphones actually have this option using standard settings.
To hide a folder, you need to select “Security” in the settings, and then set a PIN code. After that, enter the digital code. Further opening of files will be possible only after entering the password.
Password-protected folders
Note! Using standard settings is the easiest way to protect your data. But, unfortunately, on most Android devices you need to download special applications to install the encryption.
Should the function be removed?
Before you delete the entire protected system on Samsung, decide why you need to do this? This feature really effectively protects your phone and your data. I consider it one of the most significant advantages of Samsung. But in cases where a protected folder interferes with your normal work on the gadget, you should think about disabling it. These are the situations:
- You have rooted your phone and the system issues a lot of security messages and blocks programs from working.
- You installed third-party applications, but the security system did not come to terms with it, displaying annoying messages.
- It reports unlicensed programs too often, interfering with your work.
- You installed the application yourself, but it is not compatible with your phone or firmware.
These are the cases when there is nothing left to do but disable KNOX on Samsung. But if you just want to remove the protected “Secure Folder”, then you do not need to remove KNOX at all. I will tell you how to do this below.
What does the Knox directory consist of?
In total, hidden storage on Samsung devices includes several components:
- hardware (this is the Samsung device itself);
- software (hidden folder with application content);
- service (server that is responsible for managing and compatibility of the device with Knox).
An additional and one of the important aspects that is included in this catalog is Android for Work. Inside the built-in Knox folder, the security of this profile is ensured through several modification options:
- RKP (stands for real-time kernel protection);
- checking for malware DM-Verity;
- safe load.
