LG Electronics said it will unveil “a new line of exceptional smartphones at exceptional prices” at Mobile World Congress, featuring “design elements and features usually reserved for premium models”.

The company is moving away from naming the devices as part of a ‘series’, instead giving each a separate moniker – Magna, Spirit, Leon and Joy. Magna and Spirit also see the wider rollout of the company’s curved display technology, featuring a “subtle 3000mm radius curve”.

The quartet will be available in both LTE and 3G versions, which the vendor said is “consistent with LG’s strategy to expand its appeal in the mass-tier segment with different products for different networks”. The 3G and LTE versions feature “nearly identical design cues”, although the former have patterned plastic back covers while the latter have metallic rear covers.

Magna, “which means ultimate in Latin”, features a 5-inch in-cell touchscreen (“normally offered only in premium smartphones”) and is powered by a 1.2GHz or 1.3GHz quadcore processor (depending on market). It has 8MP rear and 5MP front cameras, 8GB of on-board storage and runs Android 5.0 (Lollipop).

The vendor said that Spirit “embodies the spirit of LG’s innovation”, with a 4.7-inch in-cell touchscreen that “makes the phone look slimmer while maximising display areas and minimising bezels”. Its core specifications are similar to those of Magna, although cameras are 8MP or 5MP rear with 1MP front-facing.

LG’s Leon and Joy lower the specs somewhat, moving away from the HD screens on the bigger brothers to 4.5-inch FWVGA and 4.0-inch WVGA respectively. For Leon, processing power comes from 1.2GHz or 1.3GHz quadcore chips, while for Joy the selections are 1.2GHz quadcore or 1.2GHz dual core.

And camera specifications are also different: Leon has an 8MP or 5MP rear and VGA front cameras, while Joy has 5MP rear and VGA fronts.

The devices also feature “popular UX features” originally designed for LG’s premium smartphones, such as Gesture Shot to start the camera for selfies, and Glance View to access key information easily when the screen is off.

“For millions of consumers around the world, the deciding factor on which smartphone to buy isn’t how fast or how big it is but how balanced it is. With our new mid-range smartphones, more and more customers will be looking to LG for their next handsets,” said Juno Cho, president and CEO of LG’s Mobile Communications unit.

The devices are rolling out this week in “select markets”.
