What should I do if dust gets into the edge of my phone screen protector?

A: Dust getting into the edges of mobile phone films is a common problem, especially for 2.5D films and curved screen films. Solution: ① Slight dust ingress: If it does not affect usage, it can be ignored. Dust will not damage the screen. If you think it affects the appearance, gently stick it out with the edge of the dust removal sticker (do not pry the film forcefully). ② Severe dust ingress/curled edges: If the edges of the film have curled up or a large amount of dust has entered, affecting touch or viewing, it is recommended to replace the film. ③ Preventive measures: Choose a film with a dust removal chamber (clean thoroughly before application), select a film with good edge bonding (3D heat-bent film fits curved screens better), avoid contact with dusty environments within 24 hours after application, and wear a phone case (the edge of the case can press against the edge of the film to reduce dust intake). Woowhead Guanfudun 2.5D micro-arc edge, which fits well with the edge when used with the mobile phone case. Guanfudun Qu is 3D hot-bent, with a more complete curved screen fit. It is equipped with a roller dust removal chamber to further reduce dust intake. If there is severe dust at the edge, you can contact after-sales service for handling within 7 days. If it exceeds 7 days, it is recommended to replace it (a 2-piece package costs 159 yuan with a spare).
