    I have a Samsung Galaxy phone that is out of warranty so I did the rooting. However, I cannot use contactless payments in the IKO banking app. I called the PKO hotline and it was confirmed that this will be the case on rooted phones. I read on the internet that banks block contactless payments on rooted phones for security reasons. But there are apps like Magisk that cheat on these banking apps. So, could anyone explain whether a rooted phone is really vulnerable to hacking an account by a hacker? After all, the banking app is launched only when needed and enters the password each time. Besides, there are antivirus programs for Android.

    Each interference with the soft devices creates gates for a potential thief. Think that such a person can easily take control of the device and, from the level of his computer, run the network later the program and read, for example, the Blik code and then clean your account.
    If there are programs that cheat the application, there is no big obstacle to make one that will take over all information about your device,

    Even on a non-rooted system, there is a risk of hijacking your phone. If you want to use the banking application, upload the multi-file firmware.

    It won't do him any good, because he has a flag on it.

    Now installing Magisk won't change anything because the knox flag is already loaded. If you would use Magisk at the very beginning, it would not punch the flag, now it's gone.

    What would it change for him if TWRP is required to install Magisk and this, in turn, will make a flag? Magisk allows you to hide the root from the selected application and IKO itself works on a rooted phone and does not display any messages. It is true that I have not checked the contactless payments because I do not use it.

    MagiskHide at some point was able to "cheat" the system and stating that the Knox flag is still 0x0 so it may be worth verifying. Knox's flags cannot be restored to their original state.

    Of course it is possible to remove the flag - as long as the phone still has a warranty.

    There are other tools to cheat Knox, but they don't always work.

    Well, yes, by replacing the disc with one with a loaded flag; P If you know any other way, especially for current models, I will gladly know.

    Since after the warranty, only the patch remains. But I will not agree with this lack of guarantee with a loaded flag :)

    Buddy ... I have been working in the Samsung service for many years and I know the terms of the warranty by heart ... Any interference in the OS invalidates the warranty with a small exception, but this is confidential information.

    I am glad, my friend, that you have been working in Samsung for many years - send me a phone with a stamped flag without the service history and I will delete it for you.

    Probably by replacing the motherboard and tamping it early, so that you do not have deduction after returning the part ...

    It is important that the desired effect is achieved.

    I don't use mobile payments. And for the future, there will be a lesson that root can irreversibly disable this phone functionality

Topic summary

Rooting a Samsung Galaxy phone can disable contactless payment functionality in the IKO banking app due to security measures implemented by banks. Users have reported that rooted devices are more vulnerable to hacking, as malicious software can exploit the rooting process. While applications like Magisk can potentially hide root access from banking apps, they may not restore the device's security status if the Knox flag has been triggered. Restoring the phone to its original state is suggested as a solution, but it may not be effective if the Knox flag is already set. Users are advised to consider the risks associated with rooting, especially regarding banking applications and contactless payments.
