It is the refinement of samsung s6 edge.most of the elements like design remained same but it has curve on the back and front.the best thing for this is it has micro sd card which is missing feature in flagship phones.and the sadthing is it has no ir blaster.but it is water and dust resistant.in india it is launched with exynos variant but snapdragon variant is best because they have more developers than exynos.in the performance wise snapdragon 820 is superior to exynos 8890.the special thing avout this is it has liquid cooling which does not make the device to heat up.
The performance is very good.the camera is very good especially it has 12mp dual pixel and f1.7 apperture it helps us in low lighting.as usually it supports wireless charging and fast charging.in india the exynos variant has less fast charging than the snapdragon ine which supports 3.0 if you wanna buy it please buy snapdragon variant from usa it will worth
