A3.The product is brand new. In order to ensure the quality and integrity of the screen product we provide to you, we conduct strict quality inspection procedures before it leaves the factory. Bubbles or smudges on the protective film, caused by the inspection process, are considered normal occurrences. The protective film is applied to safeguard the screen from scratches and dirt during transportation and testing. Upon receiving the package, you can peel off the film to inspect the screen for any damage. After inspection, you can reapply the film to continue protecting your screen during the installation process. Once the final installation is complete, you can remove the protective film and start experiencing the brand-new anti-glare screen!
