First generation Kindle Fire HD of Amazon's Kindle Fire line of touchscreen tablet computers was announced on September 6, 2012 and was available in two models, 7" and 8.9". The 7" version was released on September 14, while the 8.9" model was released on November 20, 2012. The 7" model was released in France, Germany, Italy, Spain and the United Kingdom on October 25 and in Japan on December 18. The 8.9" model was released in Japan on March 12, 2013 in Germany on March 13, and in India on June 27.[2][3][4][5][6]

On September 25, 2013, the 7" model was discontinued and the Fire HD second generation was released. The price of the Fire HD 7" was reduced to $139, the processor speed was changed to 1.5 GHz, upgraded from "Android based" OS to a compatible proprietary fork of Android named Fire OS 3, removed the front camera, used a new form factor and decreased the available storage options. In addition the Fire HD second generation, the Kindle Fire HDX, was introduced.

Design[edit]

Hardware[edit]

The 7" model contains a Texas Instruments OMAP 4460 processor, which is also available on the BlackBerry PlayBook 4G LTE, while the 8.9" model uses an OMAP 4470 processor.[9] All three models feature Dolby audio and stereo speakers. The 7" model's speakers are dual-driver, while the 8.9" models' are single-driver.[9] The device has two wifi antennas on the 2.4 GHz and 5 GHz bands which utilize MIMO to improve reception.[9] The Kindle Fire HD also added Bluetooth connectivity allowing users to connect an array of wireless accessories including keyboards.[9] The first generation models have an HDMI port, but this is missing from the second generation.

Software[edit]

The 2012 models use software that introduced user profiles for sharing among family members and the ability to place absolute limits on total usage or usage of individual features, called FreeTime, and tracks your reading speed to let you know when you will finish a chapter or book.[10] The OS is based on a version of Android 4.0.3 (Ice Cream Sandwich). This does not allow use of Google Play or the apple app store, limiting the number of apps accessible for the Kindle Fire HD. Kindle Fire HD software updates can be received OTA or from the support websites.[8][11][12]

The Fire HD 7" second generation uses Fire OS 3. Note that although this version is called the Fire HD 7", it is not the successor to the original Fire HD. This model is the successor to the Kindle Fire second generation.
