I am developing mobile apps. I know that Mobile shaders are the best options for mobile apps in terms of fast performance.

However, I purchased 1 Unity asset, which only works with Legacy/Diffuse shader. When I tried to replace the Legacy/Diffuse shader with Mobile/Diffuse shader, all the colors of the object turned "white" incorrectly.

Do you know if Legacy/Diffuse shader is almost as fast as Mobile/Diffuse shader for mobile apps ?

Is the performance won't be significantly negatively impacted if I have to use Legacy/Diffuse shader for mobile apps ?
