samsung galax III shader issue

[newton]

hello,
  I am programming a Rubic's cube by JPCT based on the "HelloShader" example. I have 27 cubes and I set the shader to each of them. The issue is that on HTC it performs well and on Samsung Galax III it doesn't. After that I tested the example on both of the mobiles, it just worked so fine!Why can this be?

...on Samsung Galax III it doesn't.

That's a bit vague. What does "it doesn't" actually mean in this context?
