The Galaxy S7 and Galaxy S7 edge were launched last year with Android 6.0 and the company's TouchWiz UX. The phones were updated to Nougat at the beginning of 2017, and the update brought with it a newer version of Samsung's user interface. Unofficially Grace UX, it was introduced to last year's Samsung devices through the Nougat update, but the Galaxy S8 came with an even newer version of the interface, which the company is calling Samsung Experience. The S8 came with Samsung Experience 8.1, and later, the Note 8 debuted with version 8.5.
We have seen Samsung Experience 8.1 make its way to devices like the Galaxy J5/J7 (2016) and the 2017 Galaxy A series phones, but it hasn't yet arrived on the S7 and S7 edge. We expected it to come to the S7 duo with the Android Oreo update, as it would make no sense for Samsung to spend resources on an update that simply refreshed the user interface, but it looks like the Korean giant will do just that. One of the Samsung Members community admins has said as much in response to a user asking why the S7 hasn't received Bixby or the latest UI. Well, it could be that the update the admin is talking about would be Android Oreo, as no timeline is mentioned, but it does serve as confirmation that Samsung Experience will come to the S7 and S7 edge for those who were dreading it might not.
It's important to note that Samsung Experience isn't as much of a feature update as a visual one, so S7 and S7 edge owners aren't missing out on much. Not that it's nice to know your costly flagship phone isn't running the latest software while much cheaper devices are, so hopefully, it won't be long before 2016's best flagship phones get the best version of Samsung's user interface.
