Knock Knock Feature

Very cool. But it doesn't work all the time. Is there a spot where you have to knock on the screen.

I've found the closer to dead center you are, the higher your odds are of getting it to wake up. If you search through the phone's settings, it also mentions that you should tap in the center.

This is slightly different than putting it to sleep, where you can tap any free spot on the screen .
