I looked at the S8 recently; how do you find the curved glass at the edges in use? I found the distortion distracting, and thought the colour was shifting.
In my costly experience - the curves make it guaranteed to crack the glass if dropped from above 40 cm if not using a bulky case. Mine vibrated itself off a low coffee table and onto hardwood floor, cracking three corners. Because of the curves, the cracked glass would fall off over the span of a few weeks, leaving razor sharp shards in my pockets.
And don't get me started with the non-existent palm/grip rejection.
It takes "you're holding it wrong" to a new level.
I don't have the 'edge' version. It cost extra money for what I saw as a purely aesthetic feature that I also didn't like.
Here in the UK the edge version of the S8 is all you can get.
Ah, my mistake - it's an S7! Still, it takes amazing photos.
