As I understand it to get certification Samsung have to SUBMIT the phone for testing,
The S5 comes with KNOX 2.0
Cut & Paste from the source
"The certification will allow government officials and public sector workers to enjoy the enhanced performance and rich functionality of Samsung KNOX on the Galaxy S6 and S6 edge, which both come with KNOX 2.4 built-in, allowing you to securely connect to work files and email with just a few taps."
Would the S5 have passed IDK, nor do I know what KNOX 2.4 (S6 / S6 EDGE) has over the KNOX 2.0 (S5)
So basically cops and NHS staff will now get a free ad or s6 edge because "it meets their standards". Geniuouse lol
