Android OpenGL ES Support Everywhere?

I need to get an idea of how many potential installs I'll be loosing if I choose to do my drawing in OpenGL instead of android's native 2D graphics APIs in android.graphics.*

The android documentation seems to imply that the OpenGL ES API is supported basically on all phones: http://developer.android.com/guide/topics/graphics/opengl.html

OpenGL ES 2.0 is supported by most Android devices 

Now, does that imply that even cheap commodity devices will have OpenGL ES 2.0 support? Will the cheaper phones perhaps have software rendering, or will it always be hardware rendering?

I take it that the documentation's wording of "most android devices" means that there may indeed be some phones which are running android-8, but just don't have the开发者_运维问答 hardware for OpenGL ES 2.0. But how many phones is that exactly?

Check the Device Dashboard by OpenGL ES version.
