What should I do if dust gets into Guanfudun after applying the film?

A: Dust getting in after applying the film is the most common problem. The solution is as follows: ① Dust is at the edge and does not affect the display: It can be ignored, or use a dust-removing sticker to gently stick it out from the edge gap (do not pry the film forcefully, otherwise more dust will get in). ② Dust is in the middle of the screen and affects the display: a new film needs to be applied - steps: A. Use transparent tape to stick one corner of the film, and gently pull up the film (do not completely tear it off, just pull it to the position of the dust spot); b. Use dust-removing stickers (blue stickers) to stick away the dust on the screen and the inner side of the film. c. Reattach the diaphragm; d. If there is too much dust or dust keeps getting in, it is recommended to reapply a second brand new film (a 2-piece set costs 159 yuan and has a spare). Methods to prevent dust from entering: ① Thoroughly clean the screen before applying the film. Use an alcohol bag to wipe → dry cloth to wipe → dust removal and adhesion. All three steps are indispensable. ② Operate in a dust-free environment (bathroom steam method: After taking a bath, there is less dust in the bathroom, which is a good place to apply the film); ③ Use a dust removal chamber (provided with Guanfudun) to create a closed environment and reduce the entry of dust. ④ Do not speak when applying the film (saliva droplets can also be a source of dust), and do not apply the film in places directly exposed to fans or air conditioners. ⑤ After removing the phone case, stick it on to prevent the dust inside the case from falling onto the screen. Note: ① Once the inner side of the diaphragm (the rubber surface) comes into contact with dust, it is very difficult to clean it completely. This is because the rubber surface is sticky. After dust adheres, it may not be clean with a dust removal sticker. In severe cases, it is recommended to replace it with a new diaphragm. ② Do not touch the inner rubber surface of the diaphragm with your hands, as the grease and dust on your hands will stick to it.
