A friendly reminder that isps do NOT care about you or your digital rights. Always best to buy directly from the OEM rather than from the telecommunications (unless you can't afford it). Do proper research before buying a phone!
Oh. I kind of asked ironically. Samsungs phones with Knox have been a huge pita to root and some never really made it at all. If you do get it, then you can't use things like tap to pay or other security focused things.
