Does Guanfudun affect touch sensitivity?

A: Guanfudun does not affect touch sensitivity and can be used normally. Reason: ① The thickness is 0.3mm, which is considered a relatively thin standard thickness among tempered films. Capacitive touch signals can penetrate normally (capacitive touch detects the changes in the electric field on the screen surface, and 0.3mm glass has a minimal impact on the electric field). ② The base material of Nanshan high alumina glass does not contain metal components (metals can shield capacitive signals), and the touch response is normal. ③ The adhesive layer of the film is optical transparent adhesive (OCA), which does not affect touch control. ④Guanfudun is equipped with a dust removal chamber film, which adheres tightly without bubbles and has a uniform touch. If the touch response is not sensitive after applying the film, possible causes and solutions: ① The film is too thick (0.4mm) - Guanfudun 0.3mm does not have this problem; ② There are bubbles or dust between the film and the screen, causing abnormal touch in some areas - reapply the film to remove the bubbles and dust. ③ Alignment deviation, the edge of the film blocks the touch area - re-align; ④ Mobile phone system issues - Restart the phone or check ";" "Increase touch sensitivity" Settings (Some phones have this option. It is recommended to turn it on after applying the screen protector); ⑤ Material issues of the film (such as inferior films containing metal components) - Guanfudun is made of glass and does not exist. Note: ① The edge touch of curved screen phones may be affected by the edge of the film. If curved screen users pursue complete touch, they can choose Guanfudun Qu (3D hot bending, launched in September 2026). If you notice a noticeable delay or lack of sensitivity in touch control after applying the film, first check for bubbles and Settings. If there are still problems, contact customer service.
