LG Optimus G Pro with 5.5 inch screen for Korea is confirmed9
pixel density of 401ppi which beats out the Apple iPhone 5, the Samsung Galaxy S III, the BlackBerry Z10, but is less than the HTC DROID DNA and the Huawei Ascend D2 to name a couple. The quad-core 1.7GHz Qualcomm Snapdragon S4 Pro APQ8064 is under the hood with the Adreno 320 GPU crunching the graphics.
We expect to see 2GB of RAM and 32GB of native storage which can be expanded by as much as 64GB using the microSD slot. A 13MP camera captures video at 1080p and there is a 2MP front-facing camera for self portraits and video chat. And the thing is, while 5.5 inches surely seems pretty big now, the Samsung GALAXY Note III could be 6.3 incheswhich could take the "wow" factor down a bit.
