LG's 2013 flagship G2 smartphone, which currently runs on the Android v4.2.2 Jelly Bean OS, will soon get the new chocolate-wafer flavour of KitKat OS later this month.  

The South Korean firm in its official blog said that the KitKat update will be initially released to LG G2 in its home market in December. The company declined to reveal its plans on the update release for other international markets.

According to numerous reports, the global KitKat roll out process for G2 may spread over the next few months, probably by the end of March. Network carrier SFR said that G2 owners in France can expect the new OS update in late January. Court Elliot, representative of LG's Canadian arm, confirmed that the new firmware for the flagship phone will be released in the North American country by the end of Q1 2014.

Once the new KitKat OS is released to LG G2 , it will be enhanced with smart caller id, new Hangout message app (now all text, image and video based messages are all grouped together in a single hub), enhanced memory and power management, improved voice search, wireless printing ability and other features.

Here is a brief description of key features of Android v4.4 KitKat OS:

Improved Caller-ID: If a caller receives a call from an unknown number, the phone will look for matches on the internet with local listings via Google Maps.

Priority Contacts: The new OS empowers the phone to automatically prioritise the contact list for easy access, based on the frequency of number of calls made to the contacts numbers. 

Immersive display: To enhance the entertainment factor, the new OS comes with the immersive mode, where the status bar and navigation buttons disappear into the back ground while one plays music, games and read e-books. Users can just swipe the edge of the screen to use the utility buttons.

Enhanced Message grouping: Taking a leaf out of Apple's iMessage feature, Google has brought in some improvements to the new Hangouts app. Users can find all their text SMSs and MMSs, audio and video call details all at one place. He/she also can share location and send animated GIFs.

Emoji Characters: Initially, users had to install third party app to use colorful characters in their SMS. With KitKat, the keypad comes with native Japanese Emoji emotion icons.

NFC and Wireless Printing: Google's new OS comes with improved Quickoffice app, wherein people can create and store word documents online as well as print files wirelessly on NFC-enabled HP printers.

Bluetooth MAP (Message Access Profile):  This feature enables Android devices in cars with Bluetooth support to exchange messages.

Multi-tasking: With efficient memory management, users can multi-task by opening several applications at once.

Performance: With low system requirements, the new KitKat OS is expected to bring performance enhancements and also boost battery life.
