The Amazon Fire, formerly called the Kindle Fire, is a line of tablet computers developed by Amazon. Built with Quanta Computer, the Kindle Fire was first released in November 2011, featuring a color 7-inch multi-touch display with IPS technology and running on Fire OS, an Android-based operating system. The Kindle Fire HD followed in September 2012, and the Kindle Fire HDX in September 2013. In September 2014, when the fourth generation was introduced, the name "Kindle" was dropped. In later generations, the Fire tablet is also able to convert into a Smart speaker turning on the "Show Mode" options, which the primary interaction will be by voice command through Alexa.

History

The Kindle Fire—which includes access to the Amazon Appstore, streaming movies and TV shows, and the Kindle Store for e-books—was released to consumers in the United States on November 14, 2011, after being announced on September 28.

The original Kindle Fire retailed for Шаблон:USD in 2011. Estimates of the device's initial bill of materials cost ranged from $150 to $202. Amazon's business strategy was stated in 2011 as making money through sales of digital content on the Fire, rather than through sales of the device itself.

On September 6, 2012, the Kindle Fire was upgraded to the second generation, and its price was reduced to Шаблон:USD, RAM upgraded to 1 GB and processor clock speed upgraded to 1.2 GHz. On September 7, 2012, upgrades to the device were announced with consumer availability to those European countries with a localised version of Amazon's website (United Kingdom, France, Germany, Italy and Spain).

Шаблон:As of, the Kindle Fire was the second best selling tablet after Apple's iPad, with about 7 million units sold according to estimates by Forrester Research and Шаблон:As of Amazon's tablets were the fourth best selling.

The Fire tablet line was not updated until 2015; Amazon only released Fire HD and Fire HDX tablets during that time. In 2015 Amazon made a full refresh of their tablet family where they brought the range down market as a series of budget focused devices, returning to the lower-spec Fire line and cancelling the HDX line.

In September 2015, Amazon announced the release of the Fire 7, priced at Шаблон:USD for the 8GB version that displays advertisements on the lock screen. Шаблон:As of it was the lowest-priced Amazon tablet. In June 2016, its price was dropped briefly to Шаблон:USD. This fifth generation tablet introduced a micro SD card slot for extra storage.

A slightly improved Fire 7 was released in June 2017, keeping the US$49.99 price point.

An upgraded model of Fire 7 was announced in May 2019, with a scheduled release in June 2019 and keeping the US$49.99 price point.

In 2022, Amazon released a significantly updated model of the Fire 7. New features to the basic Fire line are USB-C, Fire OS 8, a 2 MP front camera, a larger 10-hour life capable battery, and a significantly faster SoC with twice the RAM and storage of the previous generation. Though the tablet still features budget hardware Amazon increased the base price to $59.99.

Design

Hardware

The Kindle Fire hardware is manufactured by Quanta Computer (an Original Design Manufacturer), which also originally helped design the BlackBerry PlayBook, using it as a hardware template for the Kindle Fire. First-generation Kindle Fire devices employed a 1-GHz Texas Instruments OMAP 4430 dual-core processor. The device has a 2-point multi-touch colour LCD screen with a diagonal length of Шаблон:Convert and a 600×1024-pixel resolution (160 dpi density). Connectivity is through 802.11n Wi-Fi and USB 2.0 (Micro-B connector). The device includes 8 GB of internal storage—said to be enough for 80 applications, plus either 10 movies or 800 songs or 6,000 books. According to Amazon, the first-generation Kindle Fire's 4400 mAh battery sustains up to 8 hours of consecutive reading and up to 7.5 hours of video playback with wireless off; later generations all offered around 7–8 hours

Of the 8 GB internal storage available in the first-generation Kindle Fire, approximately 6.5 GB was available for content.Шаблон:Update after

The first-generation Kindle Fire has a sensor on the upper left-hand corner of the screen. This was widely considered to be an ambient-light sensor, disabled since an early software upgrade.

Colour display technologies consume much more power than monochrome electronic paper (E-ink) types; Fire offer a typical battery life of 8 hours of mixed usage, while monochrome Kindles offer 15 to 30 hours' use without WiFi—"battery lasts weeks on a single charge"—with a much lower-capacity battery.

Software

The first generation of Kindle Fire devices run a customised Android 2.3.3 Gingerbread OS. The second-generation Kindle Fire HD runs a customised Android 4.0.3 Ice Cream Sandwich OS. Along with access to Amazon Appstore, the Fire includes a cloud-accelerated "split browser", Amazon Silk, using Amazon EC2 for off-device cloud computation; including webpage layout and rendering, and Google's SPDY protocol for faster webpage content transmission. The user's Amazon digital content is given free storage in Amazon Cloud's web-storage platform, 5 GB music storage in Amazon Cloud Drive, and a built-in email application allows webmail (Gmail, Yahoo!, Hotmail, AOL Mail, etc.) to be merged into one inbox. The subscription-based Amazon Prime, which includes unlimited streaming of movies and TV shows, is available with a free 30-day trial period.

Content formats supported by the first-generation Kindle Fire were Kindle Format 8 (KF8), Kindle Mobi (.azw), TXT, PDF, unrestricted MOBI, PRC natively, Audible (Audible Enhanced (AA, AAX)), DOC, DOCX, JPEG, GIF, PNG, BMP, PSD, EPUB non-DRM AAC, MP3, MIDI, OGG, WAV, MP4, VP8.Шаблон:Update after

Because of Amazon's USB driver implementation, the first-generation Kindle Fire suffered from slow USB transfer speeds. For example, transferring an 800MB video file may have taken more than three minutes in 2011.Шаблон:Update after

It is possible to convert a Kindle Fire to a tablet running standard Android, with some loss of Amazon-related functionality, and lacking features such as Bluetooth, microphone, camera, and memory expansion.

In May 2022, Amazon announced the company were updating the foundation of the Fire Operating System. Amazon's next Fire 7 Tablet will come with the company's Fire OS called Fire OS 8, while Fire OS 7 has run on Android 9 since 2018, Fire OS 8 will be based on Android 11, which the company stated is a pretty significant upgrade to the foundational software currently powering Amazon tablets. With this development the company aims to introduce new user features such as a system-wide dark mode.

Reception

Analysts had projected the device to be a strong competitor to Apple's iPad, and that other Android device makers would suffer lost sales.

In a 2012 review published by Project Gutenberg, the Kindle Fire was called a "huge step back in freedom from the Kindle 3"; the reviewer noted that Amazon introduced a "deliberate limitation" into the Fire that didn't exist in the previous version: it is no longer possible to download free e-books from websites such as Project Gutenberg, Internet Archive and Google Books and have them stored permanently in the same places where books from Amazon are kept.Шаблон:Update after

Sales

Customers began receiving Kindle Fires on November 15, 2011; in December 2012, customers had purchased over a million Kindle devices per week. International Data Corporation (IDC) estimated that the Kindle Fire sold about 4.7 million units during the fourth quarter of 2011.

The Amazon Kindle Fire helped the company beat their 2012 first quarter estimates and boosted the company's stock in extended trading. As of May 2013, about 7 million units had been sold according to estimates. Statistics for FY2014 or Q1&2 2015 are not yet available.Шаблон:Update after

Family

Up to the present, there have been many generations of Fire tablets spread across three different feature design lines: Fire, Fire HD, and Fire HDX.

Beyond this usage, Fire is also used for a range of media devices and for one generation of smart phone.
