[android-developers] Re: Bizarre OpenGL performance on Samsung Galaxy.

Yeah, no problem:

[ro.build.fingerprint]: [samsung/GT-I9000/GT-I9000:2.3.3/GINGERBREAD/
XXJVK:user/release-keys]

I use purely Java, and a standard GLSurfaceView. The exact same
behaviour is seen with the nVidia test programs, which use Java merely
to invoke standard OpenGL ES 2.0 code in a C++ library.

Cheers,
Alan
