Both the Samsung Galaxy S7 and S7 Edge are now receiving the Android security update for March. T-Mobile has already started the OTA roll out and the Verizon will be seeding the update on March 18. The T-Mobile update carries a build number of UVS2APB8, while the Verizon’s arrives as build number VRS2APB4.
Already the two major carriers started rolling out the update, apparently, we can expect the AT&T and Sprint to start them soon. This isn’t the first update for the Edge variant, which received a critical update a day before it actually goes on sale official.
