Disabling / Destroying a camera component cause a black blinking / flickering on Android

I have this short piece of code to show an shockwave image effect.

It works fine in the editor. But on android, when I call Destroy(this); I get a very short black blinkng of the screen.

I've tried to replace Destroy(this); by this.enabled=false; but it does the same thing.

Didn't try on iOS.

If I remove this line, the screen doesn't blink. I'm totally stuck on this, any help, clue, or idea will be greatly appreciated.
