It was reported last month that LG's upcoming G6 smartphone would feature a 2880x1440 display and narrow bezels. Now, the company has released a teaser trailer for the new handset, explaining the thinking behind that unusual 18:9 aspect ratio.

LG's updated custom Android mobile UX (version 6.0) will take advantage of the G6's 5.7-inch FullVision display, mainly by allowing it to show two almost perfectly square windows next to each other when the handset is held horizontally. The extra space should improve split-screen multitasking, and the G6 offers a few extra functions while in this mode.

Apps that are optimized for the handset take full advantage of the dual display function. The calendar app, for example, will show dates on the left and event details on the right. The camera app also utilizes the feature, placing Instagram-style, 1:1 square photos on one side of the screen while letting you review those you've already taken on the other.

Additionally, there's a "Food Mode" in the camera app that adds high color quality and saturation every time you snap a meal and inevitably post it to facebook, Instagram, Twitter, etc. There's also a way to easily create GIFs by combining 2 to 100 pictures in a loop.

LG says the two screens will let users view more information while surfing the web or reading an e-book, and provides a more immersive experience when watching videos or playing games. Moreover, the G6 includes a feature that lets people easily view 16:9 ratio content in its 18:9 format.

LG claims the G6 will ignite an era of premium smartphones with 18:9 screen aspect ratios, "which is why such a wide variety of films, apps and games tailored to the 18:9 aspect ratio is sharply rising."

The G6 will get its official unveiling on February 26 at MWC in Barcelona.
