If it's a larger, cheaper version of the LG G3 you're looking for, turn your attention to the LG G3 Screen, a 5.9-inch Android device that also happens to run on LG's first proprietary octa-core chipset.

Called Nuclun (and pronounced NOO-klun), the LTE-A Category 6-capable phone pairs a 1.5GHz quad-core application processor (based on ARM Cortex-A15) with a less intensive 1.2GHz quad-core processor (based on ARM Cortex-A7) to carry out tasks.

LG told CNET in a demo that it wants to show off its exclusive and competitive in-house solution. More importantly for value-seekers, using its own product lets LG cut costs, since it can avoid buying a processor from vendors like Qualcomm.

What you get in the LG G3 Screen

The handset's nearly half-inch larger screen size and processor aren't the only differences between the G3 and the G3 Screen. It also has a 1080p HD display rather than the G3's Quad-HD 1,440-pixel resolution. Instead of using costly real metal, the G3 Screen employs black or white plastic with a brushed-metal coating.

Despite that, the phone still looks and feels pretty nice in the hand, and a curved backing helps make it more palm-friendly. The materials may not be as premium, but the plastic construction also helps keep the weight down. The G3 Screen's very large size will make it an impediment for some, since it overflows pockets and will seem large to smaller hands. Still, the size will satisfy those looking for an extra-large screen.

With a 13-megapixel rear camera and a 2.1-megapixel front-facing camera, the G3 Screen sports the same cameras, battery and laser-guided auto-focus as the G3. You'll find 32GB of internal storage and 2GB of RAM, plus a microSD card slot to pack in even more storage. A large 3,000mAh battery promises long life.

The G3 Screen measures 157.8mm x 81.8mm x 9.5mm and weighs 182g. For now it'll sell only in Korea for KRW800,000, or about $740 or £450.
