LG's new quad-core smartphone, the Optimus 4X HD, has launched in Europe today.
The Korean electronics giant said that Germany will get the Android-powered device first, followed by the UK, the Netherlands, Sweden, and Italy.
Running the latest version of Google Android, Ice Cream Sandwich, the Optimus 4X HD is fitted with NVIDIA's quad-core mobile processor, the Tegra 3.
The Tegra 3 runs on all four cores, but when in standby mode the processor defaults to the fifth, battery-saving core.
The Optimus 4X HD is also claimed to have the biggest battery among quad-core phones, at 2,150mAh, built with SiO+ technology.
LG said that in a "future upgrade" it will introduce the eco-mode to the device, that will enable users to manually shut down any of the four cores for greater power consumption and performance.
The Optimus 4X HD comes with a 4.7-inch True HD IPS display and has an advanced 8MP rear-fitted camera.
The Android interface is overlaid with LG's User Experience (UX), offering various new features such as Quick Memo, allowing users to quickly jot down memos or notes over the screen image.
"Beyond the fast processor, superb display and largest-in-class battery, the Optimus 4X HD is the first LG smartphone to feature the new User Experience (UX)," said Dr Jong-seok Park, the president and chief executive of LG Electronics Mobile Communications Company.
"As the smartphone segment consolidates even further, it's becoming more and more apparent that both great software and great hardware are crucial to stay on top of the game. LG intends to be a strong contender in both areas and the Optimus 4X HD is our proof."
LG's Optimus 4X HD is available now from various retailers, priced SIM-free from around £450.
