I'm seeing a similar problem on that device, but I haven't spent any
time looking for an answer yet. I see that you're using VBOs...I've read
somewhere that some devices have trouble with them but I don't know if
it's true or which devices might be affected. I also know that in my
case I'm also using VBOs, but I'm not rotating the texture, I'm
stretching it without a mipmap, and it's a JPEG.
Sorry couldn't be more help.

Hi,
I have a huge problem ONLY with SAMSUNG GALAXY S2 and i cannot figure
out if the problem is my code or of this device!!
ON ALL OTHER PHONES IT WORKS GREAT!!
I'm Using ONLY OpenGL 1.0.
The problem is that with the code below my game cannot draw the object
that need rotation (the objects are not visualized on the screen).
Objects with no rotation (angle = 0.0) are drawn perfectly.
ONLY on samsung galaxy s2 the rotated images are not visualized on the
screen. There is some bug in SG2 that i have to take in cosideration
or some specific initialization?
Can you help me???
Thank you in advance
public static void drawBitmap(final GL10 gl, final float x, final
float y,
final float rotate_x, final float rotate_y, final MyImage m,
final float angle) {
// Draw using verts or VBO verts.
gl.glPushMatrix();
// gl.glLoadIdentity();
final int indexPerTile = TextureManager.INDEX_PER_TILE;
final int indexRow = m.fx.row * TextureManager.INDEX_PER_TILE
* TextureManager.TILE_PER_ROW;
if (angle == 0.0f) {
gl.glTranslatef(x, y, 0f);
gl.glScalef(m.scaleWidth, m.scaleHeight, 1);
m.fx.grid.drawStrip(gl, true, indexRow, indexPerTile);// the

if (m.alpha != 1 || m.red != 1 || m.blue != 1 ||
m.green != 1) {

}
} else {
final float xt = rotate_x;
final float yt = rotate_y;
gl.glTranslatef(xt, yt, 0f);
