As if it weren’t already hard enough to decide between the HTC One and Samsung Galaxy S4, LG has stepped up their game with a new phone on AT&T that seems ready to compete in every way.LG has had a solid past few months when it comes to delivering high-end smartphones. The Optimus G line may not have been the most popular phone of 2012, but it was a quality piece of hardware that deserved respect. The LG Nexus 4 became a popular item over the holiday season, offering the latest software from Google in a sleek form-factor and an incredibly low price.It’s been a little while since we’ve heard anything new from LG, but it looks like while we wait for them to release their new flagship in the Fall we can enjoy the previously international-only Optimus G Pro.AT&T’s latest exclusive is a huge 5.5-inch smartphone with a 1080p IPS LCD display. Underneath that glass is a 1.7Ghz Snapdragon with 2GB of RAM and a 2.1MP front facing camera. The 13MP rear camera is similar to the same camera seen in the Optimus G, but with some new features in the camera app. The dual recording feature will capture the front and rear camera at the same time in recorded video, setting the front camera up as a window in the corder of the recording.What really helps the LG Optimus Pro stand out is the massive 3140mAh battery and the unique notification light. The nearly 1000mAh difference between the Pro and the HTC One is made all the more impressive due to its ability to be removed and replaced like the Galaxy S4. The single button on the front of the display has a special multi-colored light underneath it that pulses for notifications, and is completely programmable using the tools LG baked into Android 4.1.2.In terms of raw performance, the Optimus G Pro is right on par with the HTC One and the Galaxy S4. Their benchmarks exchange a few digits back and forth, but the Pro is every bit as powerful as the flagships being offered by Samsung and HTC. AT&T’s exclusivity on the phone is unfortunate, since LG’s competition is available in many other places.If you pre-order from AT&T, however, you can get a new Quick Cover folio case. These cases can wake the display when you move the cover, and turn off the display when you close it.
