Fire Phone by Amazon (2014)

The Amazon Fire Phone ranks as one of the worst tech launches largely due to its $200 price tag, which within two months was slashed to 99 cents. This phone's gimmicky 3D face-tracking feature failed to resonate with consumers, while its walled-garden app store offered fewer than 500,000 apps at launch—far less than the 1.2 million available on Google Play at the time. Compared to No Man's Sky, which eventually redeemed itself through updates, the Fire Phone never recovered from poor market reception.
