The Twitter handle @evleaks has now leaked the images of an unknown LG Smartphone, which could possibly be the LG Optimus G2 or an LG-branded Nexus 5 device.
The Droid Guy has found the dimensions based on the width of the MicroUSB connector. According to them the Smartphone could be roughly 2.5 x 5 inches, resulting a 5.5-inch display. It sports a sleek and curved bezel, but has no front physical buttons.
The mystery Smartphone is seen with a USB 2.0 charger at the bottom. Other than this, there's not much to say currently about the Smartphone.
