I know this is probably silly but are they the same ratio (as in 16:9 or 16:10)? I ask because the S7 Edge seems considerably smaller than the comparable sized Note screen. Hardly seems any bigger than the S6 screen.
It is the same ratio. As a matter of fact, they have the same resolution, just different pixel density because the S7 Edge has a slightly smaller screen. The curvature might trick you into thinking it looks different, though.
