Help Samsung Security policy updates S3 4.3

[HighSierra]

Hi,

Just got this message this morning. I've had JB 4.3 on my S3 for a couple of weeks. Just wondering if I should allow this update.
I've seen a few posts where D4 users are having issues. Just want some advice before proceeding. I thought S3 users wouldn't get these updates.

I too have had 4.3 for a few weeks and just saw this message. I proceeded with update and aside from a new icon in thd status bar (which I do not know if it's related to this) I have seen no difference.
