ES 3.0 case execution failed

[shadowP12]

I found that the OpenGL ES 3.0 test case failed to run on the Huawei Enjoy 10 Plus due to an invalid fragment shader.
I had to modify the fragment shader as follows to resolve the issue and ensure it runs correctly.

#version 300 es
precision mediump float;
uniform vec4 vColor;
out vec4 fragColor;
void main() {
  fragColor = vColor;
}
