Who would believe that an A-series phone will have features that are missing from an S-series flagship? And yet the microSD card slot is one of the major complaints about the S6. The boost in battery capacity is welcome, even though the battery itself is not removable.
The one major stumbling block may be the camera. Sure, the wide f/1.9 aperture and OIS sound great, but no 4K video feels like a big drawback. Were less worried about the drop in screen resolution, even if it seems major.
Love the phone
