When LG put the G2’s buttons on its back, it needed to give users a way to wake up their device without having to constantly pick it up. It came up with KnockOn, a nifty feature that lets you wake the device — and put it back to sleep again — by simply double-tapping on its screen.

Now the same feature can be had on the new Nexus 5 with a custom kernel.

We’ve already seen the LG G Flex flexing, but did you know that it could heal itself, too? The handset’s back has a special coating that will happily take scratches and scuffs and then slowly make them disappear. Check it out in the video below.

The LG G Flex, LG’s first smartphone with a curved-glass display, is making its way to AT&T, T-Mobile, and Sprint. The handset made its debut in South Korea this month and it’ll expand its reach into Europe in December, while those in the United States could get their hands on it before Christmas, too.

The white variant of LG’s flagship smartphone, the G2, has been available to purchase in both Europe and Asia for the past month now, but availability in the U.S. has been somewhat restricted. However, we are currently seeing signs suggesting that the white handset is on its way to the popular U.S. operator, Verizon Wireless.

Sprint has launched a handful of new Android-powered smartphones today, including Google’s brand new Nexus 5, the LG G2, the Samsung Galaxy S4 mini, and the Samsung Galaxy Mega. All four devices are available online and in Sprint stores.
