Online retail giant Amazon has recently rolled out a software update for its flagship smartphone - the Fire Phone - which was launched barely two months back.

As a result of the recently-announced first major Fire Phone software update, the operating system of the handset has been upgraded from the Fire OS to version 3.5.1. The upgraded version of the Fire OS comes with a number of fixes and updates, and brings the multitasking functionality to the Fire Phone.

The fixes and updates which have come aboard the Fire Phone as a result of the updated software include Quick Switch, application grid folders, carousel pinning, enhanced carousel email, enhanced video sharing, and 11 frame lenticular photos.

In addition, the update has also brought about an improvement in the battery life of the Fire Phone; thanks to the newest Fire OS version which brings along several updates and 'tweaks' which address the battery issue.

Fire Phone owners can upgrade their handsets with the software update by navigating through the settings menu. The update can also be downloaded on a computer and the file can then be transferred onto the Fire Phone via the USB cable that comes with the handset.
