You can torn it up, and then poste it again. You should change another film if it will not stick on. I can teach you a skill - a pasting method from top to bottom. After the film aligned at the phone, using the battery or bank cards push down from the upper, it will have substantially no blistering. There is a original mobile phone film at the surface of a new phone where has some small bubbles that look quite unpleasant. In fact, the processing method and the needed material are very simple: a facial tissue that cannot break up and water treatment methods: Moistened facial tissue wraps a finger, and then using the finger moving on the mobile phone film bubble in the appropriate strength by moving up and down or left and right, catching the bubbles close to the edge direction until out of the mobile phone film!
The problem is the film quality. You should first clean the screen, otherwise it will blister. You'd better buy the film with good quality, otherwise it can not use a long time.
