I really like my LG G Pad 8.3 Google Play Edition (or as we call it 'round the office, the LGGP83GPE), and it's a bit disheartening that the standard version isn't getting more traction. But at least Verizon's LTE model is now on Android 4.4, as confirmed by Google+ users. Verizon's standard upgrade page says that the KitKat 4.4.2 OTA update adds a few changes to LG's software skin as well.
In addition to the backend and user interface changes, at least some of which follow Google's lead (check out the white battery and signal bars), the G Pad 8.3 now has access to the Knock Code lock screen replacement found on other LG devices. Other than that, Verizon is highlighting Immersive Mode, multi-user access, and print services. At least one of our readers has found that the "OK Google" command in the Google Now launcher can be issued from any app (which, unfortunately, isn't a given). A few bugs surrounding the SIM card, the music app, and various connections have been addressed.
Check your Settings menu for the update, but don't be surprised if it doesn't appear right away - Verizon tends to stagger these software rollouts. As always, any root-level modifications made to the software might make it impossible to update, and if you do, you might lose root permissions.
