Design

Hardware

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.^[10] 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.^[10] The device has two wifi antennas on the 2.4 GHz and 5 GHz bands which utilize MIMO to improve reception.^[10] The Fire HD also added Bluetooth connectivity allowing users to connect an array of wireless accessories including keyboards.^[10] The first generation models have an HDMI port, but this is missing from the second generation.

Software

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 the user's reading speed to predict when the user will finish a chapter or book. The OS is based on a version of Android 4.0.3 (Ice Cream Sandwich). This does not allow use of Google Play, limiting the number of apps accessible for the Fire HD. Fire HD software updates can be received OTA or from the support websites.^[2][11][12]

The Fire HD 7" second generation used 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 Fire second generation. The Fire HD models second generation were updated to FireOS 4.1.1, based on Android 4.4.4, in Q3 2014.

The Fire HD 6" and 7" third generation uses Fire OS 4 "Sangria", which features profiles so each user on the tablet can have their own settings and apps.^[13]

The Fire HD 8" and 10" fifth generation uses Fire OS 5 "Bellini", which features are unknown. (Released as of 12/8/2015)
