The years biggest disappointment was , of course the samsung galaxy Note7. It simply, while the note7 seemed like a good phone at first, things just got blown out of proportion. Samsung had to recall its devices, and when even the safe batches of the device started exploding, it finally had to stop production, incurring massive losses it will be intresting to see whether, and how samsung comes back from this. Even note 7 dont have much of the decent looks. But I believe that note 8 would recover all its losses and should be a great success.
