LG G3 QuickCircle is a wireless charging window on your phone

LG is teasing the new G3 smartphone with a look at the QuickCircle case ahead of the big launch on Tuesday.

What's through the round window? It's the LG G3!

LG's new flagship phone the G3 will be revealed on Tuesday, and LG is releasing glimpses of the new phone in the lead-up. Today, the South Korean unveiled the QuickCircle case, a wireless charging case that lets you use the phone without opening the flap.


The case has a circular window so you can check the time, make a call, send a text message, take a photo, or listen to music without opening the protective cover.

LG says you can even "get an update of your health", in case you can't tell how you're doing with a quick visual check that all limbs are attached and all basic bodily functions are ticking along.

To let you know when the phone wants your attention, a feature called Smart Lighting emits a soft white glow in the case's window when a call or text message comes in. Other apps could notify you through the window as well thanks to a software development kit (SDK) that will allow app builders to do cool stuff with the case.

And you can drop your phone on a wireless charging pad or dock while it's wearing the QuickCircle, which uses the Qi standard to juice your phone without cables.

Other clever cases include the HTC Dot View case , which is peppered with small holes so when the flap is closed it looks like your HTC One M8 has a fun dot matrix display. Other devices that can charge wirelessly when a case is added include the Samsung Galaxy S4.

The QuickCircle case comes in black, white, gold, pink, and "Aqua Mint", which I assume means green.

We'll be at the LG launch event in London and around the world on Tuesday, bringing you all the photos, videos and hands-on first impressions you need to know -- check out our liveblog from the launch on 27 June at 6pm BST (10am Pacific, 1pm Eastern).
