In October 2014, the company revealed it had suffered "primarily related" to the gadget.

And last month, the Wall Street Journal reported it had laid off "dozens" of Fire Phone engineers at its Silicon Valley research-and-development lab.

"The dynamic perspective camera was pretty much seen as a gimmick which didn't really add anything to the overall experience."

Amazon is still selling its tablets, such as the Kindle and Fire. On Tuesday, the Wall Street Journal reported Amazon planned to this Christmas, along with new tablets with 8in (20cm) and 10in screens.
