Built on heavily customized Android code, there's nothing quite like the Amazon Fire Phone. Sporting a smaller version of the Fire OS seen on tablets, the Fire Phone also has some features built just for the handset.
The 3D-like effects you see on the lock screen, in maps, and elsewhere throughout the OS are called Dynamic Perspective, and they're meant to lend visual allure as well as functionality to the way you use your phone.
While we're on the topic, Amazon's own app store is where you'll find compatible titles. There are no official Google apps at launch, which may be strange for Android users and hurt Amazon's sales, though there are still plenty of other popular programs.
A scanning app built into the camera button on the side of the phone is an accurate shopping assistant -- but Firefly, as it's known, also recognizes email addresses, phone numbers, music, movies, and TV shows.
Amazon's Dynamic Perspective gives the phone a really rich, immersive lock screen and distinct personality. The phone has some flaws you'll want to know about, so skip over to our full Amazon Fire Phone review for all the pros and cons.
