knox container removal

As Knox is Samsung's security brand and you are using a Samsung phone my guess would be that that's a system feature.

 

Knox is a security vault that is a Samsung feature: it drives the Secure Folder. Anything placed in the Secure Folder is isolated from the rest of the phone: it has its own camera, gallery and any apps you install are separate from your other installed apps. It's like having a phone within a phone! Knox is very useful for separating work accounts from personal stuff on the same device; or storing things that you don't want anyone else to get to. That said, it is not removable. It's not hurting anything by being on your phone., even if you don't use it.

 

What do you think is in there and what effects do you think it is having?

 

I, too, am wondering what you're trying to do that you believe is hampered by Knox. Nothing in the Knox vault (Secure Folder) should affect any aspect of your device. As a Samsung phone, I assume it came with Knox security so it's designed to work. If you feel Knox is having a negative impact on some aspect of your phone, I would first suspect whatever you're trying to do is conflicting with Knox; and you might want to try something else.

 

basically what @Hadron said:
what is installed? and what effect on your phone are we talking about?

 

Welcome to Android Forums @Allen Stilwell

The new "Knox container" is most likely due to a firmware update released on January 22, 2021. That would explain why a a factory reset didn't remove the additional knox data from your Samsung.

To turn off automatic updates go to phone setting and look for something like "system updates" and turn off. Also, carriers force automatic firmware updates, like it or not.
