Protective film does not fit exactly to the Samsung Galaxy S3 Mini

The protective film itself is very valuable, but unfortunately does not fit exactly to the smartphone, for which it is actually betimmt.
More specifically: The product on the Beilagzettel's right, even the text on the Aufleber on film Sent envelope has the correct text ("for Samsung Galaxy S3 Mini Value Edition I8200"), but the film itself covered the protected display actually only to a part. They also not sitting centrally. They can therefore be used to protect the display but only in certain areas.
