With the release of Android version 4.4.3 this week, the long anticipated next Fire TV software update could be just around the corner. Fire OS 3.0, the Fire TV’s operating system, is based on Android version 4.2.2. While Amazon doesn’t update Fire OS as a whole every time a new version of Android is released, it’s reasonable to assume that they incorporate Android updates and bug fixes into their product’s more frequent individual software updates. It’s been speculated that the delay in a Fire TV software update could be due to Amazon’s rumored new music service. However, we know that a yet-to-be-made-public software vulnerability discovered by the rooting community exists in the Fire TV’s current software version, v51.1.0.2. This vulnerability is not unique to Fire OS, but rather it is part of Android and is expected to be fixed with Android 4.4.3. Since Amazon has been made aware of the vulnerability, it is safe to assume that they have been waiting for Android 4.4.3 to be released before updating the Fire TV’s software, in order to ensure the vulnerability is patched. Now that Android 4.4.3 has been made public and yesterdays news of a new device from Amazon on the horizon, we expect the Fire TV will soon be receiving it’s second software update.
