"Imagine a home screen of all Amazon apps - that's kind of what they are looking for," said Carl Howe, an analyst at Boston-based Yankee Group.
Michelle Taylerson, a spokeswoman for Amazon, declined to comment.
A smartphone underscores how far Amazon has moved from its roots as an online book seller.
Just as Apple has the iTunes store so consumers can buy music and videos, and the App Store for downloading mobile apps, Amazon now has similar services.
The Web retailer said this week that its app store has tripled its titles over the past year to more than 240,000 programs, primarily for its tablets, and is available in almost 200 countries. Its $99-a-year Prime membership for unlimited shipping also provides access to movies, television shows and music.
Yet the smartphone industry is an increasingly complicated market to navigate. The devices generated sales of $338.2 billion last year, up 21 per cent from 2012, according to researcher IDC.
Much of the growth has been coming from developing countries like China, where local manufacturers like Lenovo Group and Xiaomi are gaining popularity. In the United States, where Apple and Samsung are the biggest players, growth is slowing.

Those willing to spend big on smartphones also aren't always successful. Google bought Motorola Mobility as part of a $12.4 billion deal in 2012 and subsequently created its own smartphones such as the Moto G. The handset unit had just 6.3 per cent of the market at the end of February, according to ComScore. Google is now in the process of selling the business to Lenovo Group Ltd. for $2.91 billion.
Consumers may also not get as full an array of services through an Amazon smartphone as through other devices. The company is embroiled in contract negotiations with media companies including Hachette Book Group and Warner Bros over the cut of sales of certain products, resulting in limited inventory of some titles.

Still, Amazon has shown a willingness to sacrifice profits if it means gaining customers. Of its $19.7 billion in sales last quarter, the company generated $108 million in net income, or less than 1 cent of profit for every dollar of revenue. Those margin-pinching ways have been under scrutiny from investors, who have pushed the Web retailer's stock down more than 18 per cent this year.
To distinguish itself, Amazon's handset is anticipated to feature 3-D viewing capabilities that don't require glasses. Howe said Amazon also could introduce a new pricing structure like Republic Wireless that offers cheaper monthly plans because the service uses Wi-Fi connections whenever possible, instead of connecting to a wireless network.
"We shouldn't underestimate their ability to stand out from a crowded market," Howe said of Amazon.
In a nod to the competitive market, Amazon last week sent out invitations to its Seattle event with a copy of the book Mr. Pine's Purple House. The story features a man who decides to distinguish his house from others on the block by painting it purple.
The book says, "A white house is fine, but there are 50 white houses all in a line on Vine Street. How can I tell which house is mine?"
