LG took the wraps off the successor to the G Pro smartphone in South Korea today, giving press a sneak peek at the slightly larger LG G Pro 2, a phone that was originally expected to debut at Mobile World Congress later this month. Other changes include a 1W speaker, which LG says is 30 percent louder than before, along with a 13-megapixel rear camera with optical image stabilization, and a 2.1-megapixel front-facing camera.
