How to get knock on to work 100%

[phonghuunguyen]

I figured out the problem, for some reason its can change the knock on tapping speed and pressure.
I have a large finger, before I can knock on and off with a quick 2 taps. Now I can only knock off but not on, for some reason my 9 months old son can knock on all the time when he play with the phone, so I tried to copy him, imagine you are trying to pet an ANTS but very slow 2 tap and very lightly, anywhere on the screen it work, look like he play with my phone and got the phone to register the way he tap to turn it on, its frustrating, I couldn't figure out how to set it back to normal.

Mine used to turn on with any spot on the screen. It doesn't do it anymore:'(

For me it works just above the home screen buttons..
