With the announcement of the Amazon Fire Phone comes the questions of what it's running. It isn't a great surprise to hear that it's running the latest version of Amazon's own Android based Fire OS. And on the whole, if you've ever looked at a Kindle Fire then you'll be pretty familiar with what you're seeing on the Fire Phone.
You've got a pretty standard looking grid of icons as well as the trademark Fire OS recent content carousel. You can pin apps, books, music, and other content to the carousel either in a permanent spot or it'll add automatically when you open things. The carousel also show a preview widget of apps for both first and third party applications as you flip through it.
Amazon's own applications follow a three panel design, and the event demonstrated how this works in the music app. For example you've got the main interface to the application, but a gesture right with a flick of the wrist will show you synchronized lyrics for the song you're listening to. There's no need to actually touch the screen.
There are lots of what Amazon CEO, Jeff Bezos, called "small touches." For example, in the Calendar application you can instantly message all members of it from the right hand panel. When you hit the volume button, you can hit "turn to silent for 3 hours." In Messages, the right hand panel will display all of your pictures, right there, ready to share. On the lockscreen you can either have your own photo, one of the 3D ones Amazon will give you and a swipe to the side and you can have your own custom photo library.
We'll have much more on the Amazon Fire Phone so keep it locked to Android Central!
