Too bad that the explanations are in English for me did not learn that language. The cuts are immaculate, perfectly protecting covers the front of my S3. I have not managed to avoid air bubbles and it is not very nice when the phone is off. After 1 and a half months of use, I've realized that this purchase was useless for me because I have a protective cover to "flap" that effectively protects my S3. I just removed the protection this morning. It's better that way anyway. Good product for those who do not want to use it everywhere.
