Verizon has started rolling out the Android Marshmallow update to customers who have the Galaxy S6 and Galaxy S6 Edge on their network. The updates will come to users as an OTA update and it could be several days before everyone sees it. The updated version you are looking for on your device is build MMB29K.G920VVRU4CPC2 and that is the same build for either device. This update is a big one, approaching 1GB in size, so you will have to make sure you are connected to Wi-Fi before the update will download.
The update of course brings all of the goodies that are in Marshmallow like Doze, improved app permissions and Google Now on Tap. In addition, Verizon has added some software updates of
their own, improving the Live Broadcast feature they have on their network and they have made improvements to their Wi-Fi call on the device. For those of you who have the Glaxy S6 Edge, look for some improvements around apps and usage on the edge screen too. You can get all of the details about the release for the Galaxy S6 here and the S6 Edge here on the Verizon support pages.
The release of this update by Verizon continues what has been a long string of Marshmallow updates from manufactures and carriers over the course of the last 6 weeks and for consumers, this is great to see as you are getting the latest version of Android with its improved features and security.
