While working on Ramble in the Sky I encountered some interesting OpenGL issues. They are not that obvious, especially taking into account variety of different android devices. If something works on your testing smartphone (or even on 5 of them!) it doesn't mean to work on every other ones. So, if you are interested in using GLES2.0 directly, you will probably find something useful down here.
