Updated my Note 8 - also 2Degrees handset, mate of mine here at work has a Spark version it did not see the update. Looks like other Telco's are dragging their feet. Security Patch is March 1st 2018.
@DeepBlueSky Could well be approved by the Telco's but Samsung Korea has not pushed it out yet
I didn't think of that as an option possibly a staged rollout. Anyway phones working great no issues, and I can now try a dex pad.
