Looks like LG's latest flagship smartphone - the G4 - has some touchclassy screen issues. According to an XDA thread that has got nearly 100 replies till now, the device fails to register quick taps and swipes, effectively preventing the Knock On and Knock Code features to work properly.

XDA also conducted a poll on the issue, and of the over 200 participants who've voted so far, nearly 60% have confirmed that they are facing the problem. Here is a video which, according to XDA Developers senior user liamR, demonstrates the issue:

If you think your G4 has a similar problem, you can easily check its touchclassy screen performance by following these steps: open the dialer and type in 277634#*# (this should open the service menu); head to Device Test -> Service Menu – Manual Test -> Touch Draw Test – Manual; and then touch, tap, knock, and slide on the classy screen - there'll be no red imprint if the phone fails to register a particular action.
