Under the hood the device includes a 1.7-GHz quad-core Qualcomm Snapdragon 600 processor, which is paired with 2 GB of RAM. Other features include a 13-megapixel camera, 32 GB of storage, microSD support and a 3,140-mAh battery. The G Pro runs Android 4.1.2 Jelly Bean and includes many of LG's user interface customizations.

The Optimus G Pro is also sold in the U.S. by AT&T.
