Armed with a 5.9in full HD IPS display and powered by a 2.26GHz quad-core Snapdragon processor and 3GB of RAM, the G Pro 2 will also land with a large removable 3,200mAh battery.
A 13MP camera with enhanced optical image stabilisation (OIS+) also graces the G Pro 2's spec sheet, and unlike its smaller G2 brother, it can shoot 4K video along with slow motion 1080p video at 120fps.
It'll run Android 4.4 KitKat with a few LG tweaks layered on top, some of which sound genuinely useful.
Taking the 'KnockOn' screen of the G2 even further, the G Pro 2 features a new Knock Code trick which lets you unlock it by tapping on different parts of the screen, with 86,000 different combinations to keep thieves guessing.
The G Pro 2 also has a 1W speaker which LG tells us is 20 percent louder than before, as well a built-in tool to shrink down the display to between 3.4 to 4.7 inches for easy one-handed use.
The only thing we don't know about the G Pro 2 is its price and release date, but we expect to find those out at Mobile World Congress in Barcelona where we'll be wrapping our hands around the black, white and titanium versions of the G Pro 2.
