Knock on question

[Jdt0109]

Why when i Knock on does a black screen come up. I think its my camera. But i still have to unlock it but it doesnt take me to my camera... Any help is appreciated

If you just want the camera, no need to knock. Just press the Down button for about 2 seconds.

I didnt want to activate camera. I just knocked to turn screen on and it shows the camera thing

that likely means that the camera was somehow the last open app.... maybe you held the back (camera) button when turning it off last . .
