The best solution to your problem is probably to "bite the bullet" and
rewrite your code to use shaders in OpenGL ES 2.0. All major phones and
quite a few minor ones support it now.
It may be your only solution, if the Galaxy S3 has to move too many more
bits than the P350 did, or has a slower OpenGL client-server path. Or if
Motorola took too many shortcuts in maintaining OpenGL ES 1.0 backwards
compatibility.
Finally, from this snippet, we cannot tell if you are handling your buffers
correctly. For example is 'buffer' a directly allocated ByteBuffer?
