Google has been quiet about the Android 4.4.3 update to the LG G Pad 8.3 Google Play edition, and now it looks like both LG and Google are skipping that Android update in favor of jumping to the newer Android 4.4.4 revision. At this time, the update is hitting the Google Play edition as GPe devices usually are among the fastest to get the latest updates from Google.
The update will be staggered so it may not be hitting your devices just yet so you may have to wait a few days until it hits your unit. You do have to run at least Android 4.4.2 on your LG G Pad 8.3 GPe to be able to install the Android 4.4.4 update.
Both the Android 4.4.3 and Android 4.4.4 updates belong in the KitKat family and are considered incremental upgrades so you shouldn't notice any new features off the bat. Many of the changes will be under the hood in terms of bug fixes and performance improvements.
