LG had a heavy presence at this year's Mobile World Congress (MWC) where it released four new smartphones, including the company's new flagship device, the LG Optimus G Pro. Now it seems the company is preparing a new headset to be included in the Optimus LTE series and the device is reportedly named Optimus LTE 3.

The smartphone was spotted in South Korea where it is scheduled to be launched sometime later this year via SK Telecom, Unwired View reports (ViaBlog of Mobile). The device is expected to come with a model number LG F260S.

Optimus LTE 3 will be the first device in the series to run Android 4.1.2 Jelly Bean out of the box and the smartphone will include a slew of decent mid-range specs similar to the L-series devices. The rumored specs include a HD (1280x720) display and a dual-core Qualcomm Snapdragon MSM8960 processor. While the display size is not available at present, the device may pack a decent-sized 2540 mAh battery, which is a remarkable enhancement when compared to the battery capacity of its predecessor, Optimus LTE 2, which featured a 2,150 mAh battery.

The Optimus LTE 3 has a design similar to that of Optimus F7, which also featured LTE connectivity and HD display. We haven't heard an official announcement on the global release of the device yet, but as previously said, the device is definitely hitting the South Korean market later this year.

LG managed to garner a good amount of attention at the MWC in Barcelona, where it released its Optimus G Pro, which impressed a host of customers with its top specs and stylish design.

LG is pinning its hopes on Optimus G Pro to smooth its comeback. The smartphone is powered by a 1.7GHz quad-core processor from Qualcomm and sports an amazing 5.5-inch full HD display. The device runs on Android 4.1.2 Jelly Bean and comes with 2GB of RAM with the microSD card option to expand the memory up to 32GB.

However, as The Wall Street Journal notes, LG's efforts to recapture the lost glory are not free of any roadblocks. LG, which up until 2009 was the world's third-largest mobile handset maker by shipments behind only Nokia and Samsung, lacks a clear strategy when it comes to smartphones. "Its weak distribution has also been a drawback, as LG didn't have enough smartphones on store shelves, a problem the company has yet to completely overcome," the report said, quoting industry analysts.
