What is SE for Android?
These Security Updates have *something* to do with KNOX. The tagline is "Lock down your Android!" Well, I'm not too interested in "locking down" my phone. Rather the opposite: I'm already hacked off that my phone got bootlocked when I upgraded to 4.3. So I am not too thrilled about being repeatedly nagged to turn on some sort of SAMSUNG security thing that they refuse to explain beyond "It monitors your software and tells Samsung if there's a problem." Big Brother, is that you?
Worse, no matter how many times you hit Decline, it will just keep nagging. Hey, guys, it's a checkbox. It's not checked. There's your answer.
Continuing in this vein, I don't run KNOX. My phone is not a corporate phone. It has no corporate software, and no employer's IT department needs access to my phone. If KNOX is a way to have two separate and protected-from-each-other "profiles", "memory spaces", "images", or what have you, AND I'M NOT USING IT, then why do I need to download the security updates it uses?
Methinks there's more to KNOX than just an option to make Samsung phones running Android friendly for corporations concerned with industrial espionage. It sounds more like Samsung wants to make really, really sure you can only run software that Samsung likes.
So... does anybody know how to get rid of these annoying messages telling you to "accept automatic security updates" where "Accept" means "yes", and "Decline" is interpreted as "maybe"?
