FYI - CopyTexImage2D is a pipeline stall so you will want to set up
your rendering order to account for that. I'm not sure how to
optimize but I would try having it be as near to last as possible to
start with.
Thanks for the recommendation. In fact, I'm using it as the very last

Great! I'm glad you got it to work.

I finally got glCopyTexImage2D t work, using a power-of-two texture as
you suggested, and GL_RGB as internal format passed to glCopyTexImage2D
(the internal format of the texture is GL_RGBA).
glCopyTexSubImage2D doesn't seem to work though. As far as I understand
from reading the OpenGL ES doc
Have you tried copying it to a power of 2 texture instead of the
viewport dimensions? I'd test with 512x256 and see if that works.

Any updates on this one? I have been trying to copy the contents of the
back buffer into an opengl texture, but without success. I'm using the
same method mentioned in the first post of this thread:
gl.glCopyTexImage2D(GL10.GL_TEXTURE_2D, 0, GL11.GL_RGB, 0,0, w, h, 0);
where w and h are the cu
Works for me on my HTC Hero - I too could only use RGB and not RGBA.
Emulator flips the textures upside down though...
Does anyone else have more information regarding other phones? I have
an app on the app store that uses this method and I am suspecting that
it does not work for all current phon
