Please don't panic, there is a step-by-step process to remedy this situation, but you will have to be very careful and patient.
Try to gently and carefully remove the 9H Tempered Glass Screen Protector from the screen of your phone using the included squeegee card, starting from one of the corners. Avoid touching the adhesive with your fingers, hold it by the sides. Once protector is completely removed, use either the included dust removal sticker or a scotch tape to remove the dust particles.
