Interference by applying the film-removed again

Hello, Unfortunately, we did not have good experiences with the film. My daughter and I have an Archos G9 Turbo and I said, we are doing ourselves and the Tablets something good. The film sits in register and works well on. So properly cleaned up and the tablet so. And then we were off to the independence of the Tablet's. One turned out as they wished, the other jumped off the browser returns to the home screen. Performances churning out, just do not bring desired. Primitive state made on both tablet's back, the tablet's were again the "old". We have applied to us the statistics, 100%, 100% failure, what can you say?
