[android-developers] Re: Do OpenGL ES 2.0 phones also support ES 1.1?

Right now - yes, they do. AFAIK, most GLES 1.0/1.1 implementations on
2.0-standard chips are always using 2.0 internally but the driver has
1.1-compatibility shaders that it uses behind the scenes to implement
fixed-function emulation.

for your problem - if those are two totally different chips, you may
have done a few strange things that you thought were fine because they
worked on your test device but the other device didn't like them.
Correctly-implemented GLES should (in theory) work on all devices
unless they have bugs. If it's not working, you probably did
something to make it angry.
