Google has created a Security Bulletin that releases a general security update every month, and understandably, the Pixel and Nexus devices are the first one to receive them. Over the past few years, certain Android OEMs have begun keeping up the pace with Google by releasing security updates in the first week of every month, but not all mainstream brands have been a part of this movement.

In cases of network-locked devices, the software update can take even longer, as it the case with U.S. telecom companies Verizon and Sprint, which are only now releasing the month-old May security patch for the flagship Samsung Galaxy S9 and S9+.
Carrying build numbers G960USQU2ARE6 and G965USQU2ARE6 for the Galaxy S9 and Galaxy S9+ respectively, both at Verizon and Sprint (S9|S9+) the update seems to bring nothing apart from the security bump.

Additionally, Verizon is also rolling out the same May security patch as an update to the seemingly forgotten LG Stylo 2 from 2016. The mid-carder from LG never saw the light of the day after Android 6.0 Marshmallow but is currently receiving the latest security update with build number VS83520i and nothing more than the security patch with it.
