I'm thinking it's just a matter of time before Amz comes out with a phone again. They seem to be quietly building all the cloud infrastructure for it, photo storage, cloud storage, App Store, talking assistant, marketing outlet with increadable eyeballs, their own music and video streaming stores and their own OS.
Make low to mid price phones, build both Alexa and Cortana in, good speed, battery and screen and go. Add instant coupons when you walk in a Whole Foods. Bang.
