i guess your Samsung Galaxy using the cell of Qualcomm 7201A(or nearly), it comes into a conclusion that a version of libhgl.so that qualcomm provided are not correctly returned when call eglChooseConfig . i have encounted that problem as you. so just setup your own EGLConfigChooser ,and don't set the EGL10.EGL_STENCIL_SIZE which would lead to wrong results.
