We are sorry for causing trouble to you. The TP protective film may be squeezed by external forces during long-distance transportation to generate bubbles. It is recommended that you try to use a soft cloth or credit card to gently push the bubbles from the center of the screen to the outside to help the bubbles out. If the bubble problem of the protective film still cannot be solved, you can remove the protective film and use it or go to the official after-sales service center to replace the film.
