KnockCode is the new security feature on the LG G Pro 2 that gives you a handy way of unlocking your Android smartphone while also increasing its security. With Knock Code, you choose from some 86,367 combinations in a 2×2 grid. Then it’s just tap and unlock. The longer the combination, the more secure your phone is.
For a little extra piece of mind, you also can set a backup PIN code, just in case you forget.
