The delivered disc is perfectly fine, no errors, as the original ... However, the original screen on the back is dark-coated, so that the Display area in the off state is beautiful as black as night. The lack of this disc, thus the screen is completely absent after the exchange the contrast on and off sees the S3 then also as a failed China replica from. While working but happy one is not so. For me, unfortunately, remained as only the alternative of a complete display exchange.
