The Samsung Galaxy S7 edge is much better than its predecessor. It features an Always On display, an extra row of notifications on the edges, better photographic capabilities with 12-megapixel f/1.7 camera, as well as microSD card slot, hybrid SIM card slot, and water resistant capabilities.
This phone feels amazing, looks amazing, and performs amazing. However I use nova launcher so I cant comment on any touch wiz issues.
Oh and the camera is ridiculously good. Low light photos seem impossibly clear and its getting to the point where you dont need to bother bringing anything else on vacation but your phone.
