Korean manufacturer LG has used this year's Mobile World Congress event in Barcelona to unveil an all new quad-core Android-powered smartphone.

The LG Optimus 4X HD boasts Nvidia's latest 1.5GHz Tegra 3 processor, which is designed for "high-level" multimedia performance. This processor, which is the world's only 4-PLUS-1 quad-core mobile engine, utilises a fifth "battery-saver core" that handles less demanding tasks.

LG's forthcoming smartphone will run Google's Android 4.0 Ice Cream Sandwich OS, and will arrive packing a True HD IPS display.

Gaming-wise, the LG Optimus 4X HD features a 12-core GPU that's said to deliver a "visually rich experience and console-quality game playability".

Finally, you'll be able to take photographs using the device's eight-megapixel rear-facing camera and 1.3-megapixel front-facing camera. You can store your snaps using the phone's 16GB of internal memory.

The LG Optimus 4X HD will initially launch in Korea, and will hit the UK at a later date.
