LG has officially announced its new L Series III lineup of uncompromising mid-range smartphones that are set to debut at the Mobile World Congress (MWC) 2014.

A week ahead of the big event, LG has revealed its upcoming trio of smartphones that will expand its L Series. The LG L40, LG L70 and LG L90 will not come at the high end of the market, but will nonetheless rock Android 4.4 KitKat out of the box and will not sacrifice style or design for affordability.

"With the original L Series and L Series II having enjoyed tremendous success worldwide, the L Series III is expected to continue to momentum with its handsome design and practical user benefits inspired by LG's more premium G Series," the company touts in the press release.

"In addition to inheriting the refined design aesthetic that is synonymous with LG's premium devices, the L Series III provides an array of user benefits that extend far beyond a simple upgrade," adds Dr. Jong-seok Park, president and CEO of LG Electronics Mobile Communications Company. "From the design to the OS to the UX, the L Series III exemplifies LG's commitment to bringing the best smartphone experience to as many customers as possible. We're confident that the L Series III will be a strong volume driver in 3G markets."

The L Series III smartphones will sport 3.5-inch, 4.5-inch, or 4.7-inch displays for the L40, L70, and L90, respectively. LG lists several other features as "depending on market," but all three smartphones come with 3G only, and run Android 4.4 KitKat.

The upcoming LG L40 will come with a 3.5-inch display with a modest resolution of 480 x 320 pixels and pack a 1.2GHz dual-core processor under the hood. It will also feature 512MB of RAM and 4GB of internal storage capacity, and will come with either a 1,700 mAh or a 1,540 mAh (depending on market) removable battery. In terms of camera, it only has a 3-megapixel rear shooter.

The LG L70 takes it up a notch and comes with a 4.5-inch IPS display with a 800 x 400 resolution. It packs the same 1.2GHz dual-core processor and 4GB of internal storage capacity, but features 1GB of RAM. Other specs include a 2,100 mAh removable battery, an 8-megapixel or 5-megapixel rear camera (depending on market), and a VGA front shooter.

Lastly, the LG L90 comes as the higher-end model of the trio, sporting a large 4.7-inch IPS display with a resolution of 960 x 540 pixels. This model packs a quad-core processor clocked at 1.2GHz and doubles the internal storage capacity for a total of 8GB, but has the same 1GB of RAM as the L70. Other specs include an 8-megapixel rear camera, a 1.3-megapixel front shooter, and a 2,540 removable battery.

LG will show off its new L Series III smartphones next week at MWC 2014, which kicks off on Feb. 24 in Barcelona. The company has not offered any additional details at this point, but it will surely provide more information regarding the handsets' price and availability at launch.
