Remember how the LG Optimus G Pro saw its biggest leak in Japan? We might just know why. Local carrier NTT DoCoMo has confirmed the new flagship's existence as part of a spring device lineup, and it's everything that was rumored just days ago. LG is adding to the rapidly burgeoning crowd of 5-inch, 1080p phones while freshening the formula we'd seen in the regular Optimus G: there's now a quicker, 1.7GHz Snapdragon S4 Pro chip, a heftier 3,000mAh battery and Jelly Bean (albeit Android 4.1, not 4.2) out of the box. Other elements are familiar carryovers, such as the 2GB of RAM, 13-megapixel camera, 32GB of built-in storage, a microSDXC slot and LTE. Japanese buyers will have to wait until early April to pick up an Optimus G Pro for themselves; as LG hasn't confirmed the phone separately, other countries' launches are still up in the air.
