As expected, Verizon has started pushing out a new update to Samsung Galaxy S7 and S7 edge units on its network. Arriving as software version G930VVRU4BQK2 and G935VVRU4BQK2, respectively, the update fixes the Wi-Fi WPA2 security issue known as the KRACK vulnerability.
In addition, the update also includes Android security fixes for November, bumping the security patch level to November 1. As is usually the case with OTA roll outs, it might take time for the update to hit your device, so be patient.
