But let's be honest, this is android, so it was probably designed by 12~75 product managers responsible for a single small feature each, which they personally never used.
they had the opportunity to work with the most cool and anticipated new tech... and they just slap two phones back to back like it's not their job to do anything. How can someone screw things so badly?
the meetings probably went
PM for some small samsung video chat app: "but if i open it, i can't have video chat! we must have front facing camera on this side too!"
PM for some Advertising as Notification OEM deal: "but we get paid more for non-flip phones! we have to show notifications without opening!"
PM for s-gear: "what do you mean an innovative wrap around the wrist phone?! this will kill sales of smart watches! let's keep this idea for the 3rd version ...maybe"
