Android 2.3.4, a minor update to the Gingerbread-named release of Google’s operating system for smartphones has leaked onto the web ahead of the official carrier release. For now, it’s only available for Samsung’s Galaxy S II smartphone through the means of a downloadable firmware file. Even though it’s only a minor update, Gingerbread 2.3.4 carries a few little surprises worth mentioning. For instance, the update enables Google Talk video calling on Samsung’s device and battery life improvements are also being reported. Some early adopters also claim improved reception due to an updated baseband software. If you’re eager to take the plunge and install the new firmware yourself (and void your warranty in the process), check out a handy guide and download links over at the SAMFirmware blog.
