Samsung have finally begun to push the Android 4.3 update that everyone was expecting before the end of October. Okay, so Samsung are a little late, but the update is here none the less and users should begin to see the OTA update hit their phones already with some users in Ireland already reporting that it has arrived. Like always, the roll out happens per region and some countries may not see it right away and further more, carrier specific devices may not see it for sometime.
Android 4.3 for the Galaxy S3 includes support for the Galaxy Gear smart watch which launched along side the Galaxy Note 3 a few months back as well. Samsung have also included a somewhat updated UI, voice controls and screen modes, much like what we see on the Galaxy S4.
