GLES20.glUseProgram(0);

I am using this shorthand code to get a blank screen that renders at 60fps on my tablet:

GLES20.glUseProgram(0);

I have not created a program 0.

I wonder if this will work on other devices? I don’t get any errors, and I wonder if program zero has a special meaning in OpenGL.

I am of course being lazy and should write a proper shader program…
