For those over in Korea LG has now gone all official with their latest addition to their Optimus range of devices with the official announcement of the LG Optimus Big, a smartphone that features a rather large display.

According to an article over on Engadget by way of the Boy Genius Report, Ubergizmo and U+, the LG Optimus Big is expected to release in Korea today the 28th of April, but as yet there’s no indication whether the LG Optimus Big will release anywhere else.

Spec wise the smartphone swaps out the glasses-free 3D display seen on the LG Optimus 3D for a 4.3-inch WVGA NOVA display, sports a 1GHz dual-core processor, 5 megapixel camera, front facing camera, GPS, 16GB storage, HDMI out, WiFi, Bluetooth 3.0 and runs Android 2.2 Froyo.

The LG Optimus Big is LG’s largest Android handset so far, and no doubt at some point in the future that Froyo will get updated to Android 2.3 Gingerbread. Price wise LG hasn’t come forward with any expected price tag on the device as yet.
