The update should be rolling out today but as is the case with most updates, we expect that the rollout will most likely be staggered, meaning that it will probably be released in phases so don’t worry if you haven’t received your update yet. According to AT&T, the update will bring about an improved user interface, improved battery efficiency, a boost in speed, Printing in the Cloud, and an improved Knock On in which they claim that responsiveness of the feature has been increased. For those who can’t wait, you can head on over to your phone’s Settings, General, About phone, Software Update, Update Now to try and pull it manually. In the meantime LG has also released a video in which they compare the LG G2 running on Jelly Bean versus one running on KitKat. The differences are noticeable so you can check that out to get an idea of what to expect post-update.
