Unfortunately, VZW is not pushing out security updates for the Samsung Galaxy S9/S9+ in a timely manner. The "latest" firmware for my Galaxy S9+ is dated 10 March 2018, which includes Android® Security Patch Level of 2018-02-01 (nearly four months old). Samsung has released three (3) subsequent security updates since the 1 February baseline (dated 1 March, 1 April, and 1 May 2018 since that time, and the 1 June update will be released in a few days) -- each of these updates addresses multiple Critical (as well as additional High, Moderate, and Low) level Common Vulnerabilities and Exposures (CVEs). Unfortunately, security updates are more than just "everything (being) okay with your phone" or noticeable performance issues. They are just as important as (and probably more important than) functional updates affecting the usability of the device. Just ask Equifax about the effect of unpatched systems on their customers, their reputation, their stock value, etc. Samsung releases security updates for Android OS related security issues released by Google as well as patches for Samsung-specific security issues on a monthly basis for "current" models (defined as Galaxy S series (S9, S9+, S8, S8+, S8 Active, S7, S7 edge, S7 Active, S6 edge+, S6 Active), Galaxy Note series (Note 8, Note 5), and Galaxy A series (A5 (2016), A5 (2017), A8 (2018)). The updates are dated the first day of each month, and they are typically released (i.e., made available to carriers) by Samsung within a few days (reference https://security.samsungmobile.com/workScope.smsb). Verizon definitely has the latest (dated 1 May 2018) as they have already released updates on 23 May 2018 for both the Galaxy S8 and S8+ including Android® Security Patch Level of 2018-05-01: (https://www.verizonwireless.com/support/software-updates/) Samsung Galaxy S® 6 last updated 05/02/2018 Samsung Galaxy S® 6 edge last updated 05/02/2018 Samsung Galaxy S6 edge + last updated 04/26/2018 Samsung Galaxy S7 last updated 04/19/2018 Samsung Galaxy S7 edge last updated 04/19/2018 Samsung Galaxy S8 last updated 205/3/2018 Samgung Galaxy S8+ last updated 05/23/2018 Samsung Galaxy S9 last updated 03/10/2018 Samsung Galaxy S9+ last updated 03/10/2018 The security updates released by Samsung to the carriers are OS-specific, not device specific. Every other "current" Samsung device supported by Verizon Wireless has security updates newer than those on the Galaxy S9 and S9+ (dated 1 February 2018).
