LG has officially unveiled yet another accessory, the QuickCircle flip case, for the upcoming flagship handset to carry out multiple functions without opening the cover.

LG, the popular smartphone and electronic company, is learning the tricks and trades of building excitement around a major product release. With less than a week to go for the release of LG G3, the company's latest flagship smartphone, the company has unveiled yet another accessory for the upcoming handset. The QuickCircle by LG is a work-of-art that redefines the use of flip covers beyond protection of the screens.

The flip case for the LG G3, which is set to debut in London this Tuesday, features a circular window on the front to help users carry out important functions without opening the cover. The circular window is a far cry from the company's previous square one found on the G2 and gives a better view and access to multiple functions.

"The smartphone ecosystem is constantly evolving - no longer are cases just for protection from the elements and bumps and drops," Dr. Jong-seok Park, president and CEO of the LG Mobile, said in a Thursday's press release. "They're the perfect accessory to build in extra features that add more value to a mobile device. With QuickCircle Case, we've exceeded the baseline by making it customizable to better fit users' needs."

According to LG, the folder-style case gives sufficient window for users to check important information such as check date, time and weather and snap photos, view gallery, send text messages, place calls, listen to music or even get an update of their health from the connected fitness bands it unveiled last week.

Design wise, the QuickCircle cover replicates the G3's original textured lines and grip. Surrounding the circular window on the front cover is a soft, white, circular glowing light that reacts to the case opening and closing operations or when a call or a text message is received.

The pricing and availability details on the QuickCircle remain scarce but the company is likely to shed more light during the big event next Tuesday. LG, however, confirmed the flip cover will arrive in five colors, including Metallic Black, Silk White, Shine Gold, Aqua Mint, Indian Pink.
