Amazon Fire Phone

Amazon's Fire Phone crashed harder than any major smartphone launch, killed off in under 12 months. Its headline 3D face-tracking, using four front cameras, added zero utility and drained battery life 25% faster than the average flagship. Priced at $199 on contract—matching the iPhone 5s—it locked buyers into Amazon's app store, which lacked 95% of top Android apps. Compared to 3D Television (#10), which at least saw passive adoption across multiple brands, this phone failed before most stores restocked, with Amazon writing off $170 million in unsold inventory.
