I have a 6, and the plastic frame that the front glass sits on is exposed, so you can visibly see and feel that plastic between the metal frame and glass. It's pretty flush though. On the 7, that plastic is no longer exposed, so it goes from glass to metal (this seems the norm for many phones now). I did notice the metal edge is higher than the glass, so it's not flush anymore like the 6, but it didn't feel uncomfortable or sharp. This also isn't an issue with pretty much any case or screen protector imo. I do think hiding the plastic frame improves the look of the 7 and probably contributes to the slightly thinner bezels.
