Re: How reliable is Verizon in sending out security updates.

Novice

You are missing the point completely. Users cannot install patches from Google or Samsung that are not made available by VZW. Samsung has released two updates since the "latest" that you quote -- unfortunately, this "latest" only includes security updates as of 1 February 2018 (the 1 March 2018 and 1 April 2018 updates are not included!).
