The iPhone-killer from BlackBerry that killed BlackBerry. The Facebook phone nobody asked for. The Amazon phone that had five (yes, five) cameras on the front. The Samsung flagship that literally went up in smoke. These are just some of the examples of phones that were supposed to be groundbreaking but flopped miserably. Some failed because they arrived too early. Most failed because they misunderstood what people actually want from a phone, and they came from companies scrambling to out-iPhone the iPhone.
