android - GL_OES_texture_float not supported on OpenGL ES 3.0 device in a 2.0 context? -

i've got opengl es 2.0 app depends on gl_oes_texture_float extension. pretty much every device in past 3 years has it, that's not problem.

however, using galaxy s5 adreno 330 gpu, i've got problem. adreno 330 supports opengl es 3.0, includes float texture back upwards natively, no extension required. , indeed, grabbing extension strings opengl on device not study gl_oes_texture_float valid extension.

but when using opengl es 2.0 context on device, usages of float textures fail bind, though has capability since gpu supports 3.0. appears it's not working because i'm in 2.0 context, , no longer study extension.

has else run scenario this?
