After the success of the LG Optimus G, available now for Sprint, AT&T and global carriers, it’s not too surprising that we’re already beginning to hear rumors of its successor, the Optimus G2. While the following is unconfirmed and should be taken with a grain of salt, the rumored device purportedly features a 1080p Full HD display (5-inch FHD screen already announced), a 2 to 2.5 GHz quad-core Krait processor (possibly Qualcomm’s MSM8974 chipset) with Adreno 320 GPU, a minimum of 2GB of RAM, 13 megapixel or higher camera, and Android 5.0 Key Lime Pie. The tipster claims this one will debut in Q3 of 2013.
