Exactly one week after the flagships launch, T-Mobile has today started rolling out this month’s Android security update to all its carrier-branded variants of the Galaxy S7 and Galaxy S7 edge located in the United States. Verizon has also announced that it too will be pushing out the upgrade later today.

Although T-Mobile doesn’t specify that this is the March security update, Verizon Wireless’ upgrade page reveals that this is the most “up to date” version of the open-source operating system. T-Mobile’s firmware carries build number VS2APB8, whilst Verizon’s comes with the build number VRS2APB4 attached.
