Today US Cellular has finally started rolling out the updates to Android 7.0 Nougat for its versions of Samsung's flagships from last year, the Galaxy S7 and S7 edge. This comes around eight months after Google's initial Nougat release became available, and three months after Samsung's first Nougat builds for these phones started going out.
So you definitely can't accuse US Cellular of being fast at this whole update thing. Still, owners of S7 and S7 edge devices purchased from the company can now look forward to the new user experience Samsung introduced alongside the Nougat update.
You're looking at about 1.5GB in terms of update file size, so maybe make sure you're on Wi-Fi before grabbing that. Once you install the new release, your US Cellular Galaxy S7 will be on build G930R4TYU4BQC5, while the S7 edge gets G935R4TYU4BQC5.
