Amazon's Fire Phone has one of the more interesting user interfaces to reach consumers this year. Here's an in-depth look at how FireOS, Dynamic Perspective, and FireFly really work.



The Fire Phone may be based on Android, but the UI is all Amazon's. It relies on a carousel system for general navigation, and each carousel item offers a glimpse of the content offered inside that particular app. The UI also relies on 3D effects and gestures to reveal more information and screens. It's an interesting effort on Amazon's part, but often times feels gimmicky.

In related news, iFixit has taken Amazon's Fire phone apart to see how and what it is made of. Judging by the 3/10 score, this is not the easiest phone to repair.
