As Samsung and Apple continue to corner the smartphone market, other handset manufacturers are still bringing out their competitor smartphones. Whether or not they make any headway may have to do with branding as much as the hardware they are able to pack into the devices.

Today, LG announced its latest product, the Optimus G Pro. The smartphone will feature a 5.5-inch screen with a 1920 x 1080 resolution – an incredible 400 pixels per inch. It’s a display that’s less than two inches away from mini-tablet territory, and clearly positioned to compete with Samsung’s 5.5-inch Galaxy Note II smartphone.

The Korean manufacturer has also packed a huge 3,140mAh battery into the G Pro. The processor is a 1.7GHz quad-core Snapdragon, and the smartphone comes with 2GB of RAM. 32GB of memory is standard, but the device will also have a microSD card slot. The cameras (13MP front/2.1MP back) are an upgrade even for this class of smartphone, and the G Pro will ship running Google’s Android 4.1.2 Jelly Bean OS.

“The Optimus G Pro was developed specifically to deliver vivid and superb picture quality in a large display smartphone form factor,” said Jong-seok Park, CEO of LG Electronics Mobile Communications. “We will continue to expand our position in the premium LTE smartphone segment with our superior display technology and unique user experience.”

It’s clear that LG is making a play for high-end consumers who want a long-lasting device with which to play HD games and video, and the price of the Optimus G Pro will no doubt reflect that. Whether the company can make a dent in Samsung’s impressive Galaxy Note sales remains to be seen.
