Check out the Android 7.1 Nougat beta running on Galaxy S7 edge

The Android 7.1 Nougat update beta for the Galaxy S7 and S7 edge is already hitting the Korean versions of these handsets, just as promised, and we knew it won’t be long before one of the testers there posts some screenshots and videos for the world to see.

Bear in mind that this is not the final version of the Grace UX variation which will hit your S7 and S7 edgesoon, but rather a testing release meant to iron kinks out, so ultimately the interface and functionality might undergo some changes for the official rollout.
Samsung already promised that some of the Note 7’s Grace UX features, like the new Always-on display options, will appear on the Galaxy S7 and S7 edge with the Nougat update, and it seemingly delivers.
