Back in 2013, LG introduced KnockOn, the ability to double-tap on the G2’s screen to unlock it. The next year, the company followed up with KnockCode, a more secure version which allowed owners of the LG G Pro 2, G3 and others to secure their devices using a pattern of taps.
This year, starting with the LG G Flex 2, the Korean company’s trying something a bit different. “Peek” is a feature of the G Flex 2 that gives you a small preview of what’s going on on your device, without having to turn it on.
