The tempered film is to prevent the phone from crashing when the screen is broken. Not to scratch the flowers. Ordinary film is 3H hardness, use a few months will not have too many scratches, the reason for the selection of tempered screen is because: hardness of high toughness low, the mobile phone fell, can be very good to prevent broken screen. When the mobile phone dropped on the ground, the impact is very large, the tension over the big screen broke. Tempered film toughness low when the cell phone tension when the film will withstand tension so greatly reduced the main screen to bear the tension.
