Thanks for the reply William. As far a I understand, every firmware after MDK on the Galaxy S4 comes with Knox enabled. Flashing any firmware or custom recovery will trigger Knox and void the warranty. This makes any modification of the Verizon S4 impossible, other than ineffective subversive hacks that attempt to bypass the locked bootloader. Furthermore, I understand that the Galaxy S5 and future devices will ship with Knox 2.0, an even more intensive framework lock. While it is indeed still possible to modifiy devices (other than probably the Verizon and possible AT&T models, which will ship with locked bootloaders), this is still against the spirit of Android, as triggering Knox will void the warranty. I feel you are alienating your core user base, the same power users that publish reviews of your devices that are read by thousands of readers. While I understand the need for Knox as a security mechanism, which may seem vital in the enterprise market, I also feel that you must allow a functional method to enable and disable Knox without consequence to the user's ability to modifiy their systems. Thanks again.
