The update will now allow you to use your LG Optimus G Pro to control an LG Smart TV from 2012 or later, using the phone as a "Magic Remote Pad" or as an input device for browsing the web, and for typing. The Value Pack also brings the ability for users to start recording a video, stop it, and then later resuming the recording from the same file. And the most important change is the addition of 800 new color emoticons. And yes, the Value Pack also offers the usual assortment of bug fixes and whatnots (Gotta love those whatnot updates!)
A couple of cool AT&T features that are part of the update include Unused Apps, which tells you if an app you have installed hasn't been used in a while and reminds you that it can be uninstalled. To access that feature following the update, you need to go to Settings> Apps> Menu> Unused Apps. You will also find shortcuts to the AT&T Data folder so that you can try to modify apps that have been using more data and consuming more battery life than they should.
The Value Pack is being sent out OTA which means it could be a few days before the notification pops up on your LG Optimus G Pro. But don't fret. There is a way to try to pull it out manually. Go to Menu > Settings > General > About phone > Software update > Update Now. AT&T suggests you be connected to a Wi-Fi signal while downloading the update.
