In the UI we can see the shortcuts to activate NFC, Bluetooth, WI-Fi, and the 3G or 4G data connection along with a Q Remote button. We have seen LG has used Q Remote on various devices that include the successor of LG G3, and it uses an infrared blaster to control all other applications around the house. The big buttons on the notification panel has been replaced by smaller icons and Google is trying to make a flatter look for the Android icons also as what we see in the UI that got leaked.
LG is working with prototypes of the next G3 which is said to come with a swipe fingerprint sensor, or retina scanning technology, making a difference with Apple iPhone 5S which has a area-type fingerprint sensor.
In August 2013, LG showed off a prototype 5.5-inch smartphone screen boasting a 2560 x 1440 pixel resolution, which it referred to as Quad HD.
