LG, slightly earlier than anticipated, is currently in the midst of rolling out the eagerly-awaited Android 4.4.2 KitKat over-the-air (OTA) update to all models of its flagship smartphone, the G Flex, currently located in the United States. In terms of added functionality, the upgrade brings KitKat and Knock Code to the handset, complete with the usual bug fixes, speed optimizations and stability improvements that we’ve grown to expect from any major software update.

For those unaware, Knock Code is a development from the incredibly-popular Knock On function that made its debut appearance last year, which enables users to power on their smartphone by simply tapping the screen in any one of 86,367 different combinations.

The full changelog for this rather hefty 300MB update can be seen below:

• Android 4.4.2 OS upgrade.
• LG Knock Code.
• Improved system performance.

If you reside in the United States and own either an unlocked or carrier-branded variant of the LG G Flex, and have not yet received the OTA update, you can head into “Settings,” then “About Device,” and select “Check for Updates” to manually scan for the upgrade.
