Thank you for the information you provided and thank you for your time to answer my questions . Now my mind is more open about knox, because honestly this is my first phone from samsung that I modified.I do not know since I do not use any of these apps and for better privacy never intend to do.
much hearsay and speculation:
I choose my phones via tech specs (processor, small size, OLED) and the ability to root and third party ROM support (esp. LineageOS).
The first thing I do on SAMSUNG devices is a proper debloat.
