Optimus GK is also the first real competitor to Samsung’s Galaxy S4 from the company, as LG’s other high-end smartphones either lack on from the specs front and are too big to compete with the Samsung flagship.
LG Optimus GK is powered by 1.7GHz Qualcomm Snapdragon 600 quad-core processor. It features 2GB of RAM, 16GB of internal storage with microSD card slot and 3100 mAh battery. The phone also comes with a 13-megapixel rear camera and 2-megapixel front shooter.
The company has also included several software customisations on Optimus GK, including the recently introduced Dual-Recording feature that allows simultaneous video recording from both front and rear cameras and saves the front camera input in as a part of rear camera input frame. Other software tweaks include Smart Camera, Dual camera.
The phone will initially go on sale via Korean telecom operator KT beginning next month. There is no word on the broader global availability right now.

Dude only s4 comes in your mind to compete .what about Htc One which is the world’s best looking smartphone ever.and in software n hardware as well.
In their defense, the UI and hardware of this phone looks a lot like the S4..
HTC One may be good looking, but so was the One X compared to S3. LG on the other hand competes directly with Samsung, especially in their home market (Korea).
Until HTC catches up with Samsung in terms of support and marketing, people aren’t going to switch. One X had several hardware and software problems, some of which are still not fixed (black screen, wifi connectivity, etc.).
im sorry but this phone is ugly , but in comparison to s4 its a supermodel and that 3100 mah battery on a 5 inch screen is rather nice .
