LG G Flex smartphones on Sprint to begin receiving KitKat and Knock Code update this week

Sprint customers using LG’s popular G Flex smartphone will start receiving the Android 4.4, KitKat, operating system upgrade beginning today, April 28, via an over-the-air update.

With the Android 4.4, KitKat, update, LG G Flex receives a significant speed boost, allowing the device to run applications faster and, with the Chromium engine, Web browsing is also quicker (based on internal testing). Additionally, G Flex will now:

  • Play music more efficiently
  • Support a battery-saving location mode, extending battery life so users can surf the web, watch video or read emails longer
  • Support a useful new feature called Google Cloud Printer that makes it easy to print documents via Wi-Fi or a Bluetooth connection

Additionally, LG G Flex users will also begin receiving the Knock Code update starting this week. LG previewed Knock Code earlier this year at the 2014 Mobile World Congress. The feature is a more secure, private way for users to unlock their smartphones by using a customized pattern of knocks or taps on the screen. Knock Code is convenient to access, circumvents environmental variables that biometric technology is susceptible to and can be more secure.

How Knock Code Works:
The smartphone display is divided into four invisible quadrants. The user taps or “knocks” anywhere from two to eight times in the quadrants in a specific sequence. These personalized “knock codes” leave no visible outline for the pattern used.
