Going forward, it seems Samsung's Galaxy S lineup will only come with dual-edge curved displays. The new mobile chief for Samsung Dong-jin Koh said in an interview:
Samsung has considered that it would make the edge display as the identity of the Galaxy S smartphone lineup if the company can provide consumers differentiated user experience through software and user-friendly functions (for the curved screen).
For the last two generations we had a flat screen and an edge variant for the Galaxy S6 and S7. Both years., the Edge variant was more popular which made Samsung go with a curved screen variant of the Galaxy Note 7. The success of the Galaxy Note 7 will decide the fate of the Galaxy S8, whether it comes in two variants or not.
Personally I felt that the compact size of the normal Galaxy S7 is a huge reason why it's selling so well and Samsung should stick to a smaller, more compact S8 and a larger Edge variant.
