Japanese carrier NTT DoCoMo has today unveiled the LG Optimus G Pro, a successor to the flagship Optimus G, which offers a much-improved display, a faster processor, and a bigger battery. The device comes just four months after the Optimus G was announced, and it aims to compete with the latest crop of smartphones that pack a full high-definition 1080p display, such as the HTC Droid DNA, and the Sony Xperia Z.
