Received my black S7 from T-Mobile today. Quite overwhelmed, so far the phone has outperformed my expectations. Been using iOS(iPhone 6 Plus) for the past year and Nexus before that. I kinda hated all the skins on Android. I must say, Samsung has come quite a ways with TouchWiz, just as smooth as stock Android.
Still getting used to the many "S" features, but the the one that stands out for me is the Smart View, mirrors the screen of my phone all three of my Roku boxes and my TiVo without any lag or buffering and WITHOUT the need of any installation or any pre-setup.
Always on Display is a nice feature, but I'd rather save the battery(I know only 1%/hour, but still).
Build quality superb, feels like a premium phone as it should. Well done, Samsung!
