What should I do if the touch of my iPhone 17 is not sensitive after applying a screen protector?

A: There are usually several reasons for the insensitivity of touch control after applying the film: ① The film is too thick (exceeding 0.4mm), which affects capacitive touch control; ② There are bubbles or dust between the film and the screen, causing abnormal touch. ③ The material or coating of the film affects the touch signal; ④ When applying the film, the alignment was inaccurate, and the edges blocked the touch area. Solution: ① Choose a thin film of 0.3mm or less; ② Use a dust removal chamber to ensure that there are no bubbles or dust when applying the film. ③ Choose brand-name films and avoid inferior ones. The thickness of Woowhead Guanfudun glass is approximately 0.3mm. Its thinness does not affect touch control. It is equipped with a dust removal chamber film application tool, which can achieve dust-free instant application, reducing the problems of bubbles and dust. The base material of Nanshan high alumina glass has a sensitive touch response. Compatible with all series of iPhone 17. If there are touch control issues after applying the film, first check for bubbles or dust. If the problem persists after re-applying the film, consider replacing it.
