As expected, Amazon introduced its smartphone, called the Fire Phone, at an event in Seattle.

The phone has a 4.7-inch screen, aluminum buttons and a high-definition LCD display, among other features.
As previously reported, the phone has some 3-D functionality, which Amazon CEO Jeff Bezos called "dynamic perspective." This allows, among other things, the user to scroll through applications (like a set of phone numbers) just by tilting the phone, rather than touching the screen.
Bezos said this is accomplished by a series of front-facing cameras that track the user's perspective, in order to render the phone's interface in 3-D.
The phones are priced at $199 for 32 GB, or $299 for 64 GB, with a two-year contract with AT&T, or $650 without a contract. It's available for pre-order Wednesday, but starts shipping July 25.
The company's stock was up about 3 percent after the announcement.
The Fire will also feature unlimited photo storage, plus access to Amazon's streaming music service for Prime members, Bezos said.
Bezos also introduced a service called "Firefly," wherein the phone can instantly identify products using the phone's camera, and add them to your Amazon account.
"They are entering a very established market and they are trying to be a new player, and even with a name like Amazon, it's not going to happen," said Kevin Paul Scott, co-founder of the ADDO Institute, a branding consultancy firm.
"It's really a branding issue. People do not associate Amazon with phones, so regardless of how good their phone is, it won't catch on."
