What should I do if there are bubbles after applying Guanfudun film?

A: Bubbles after applying the film are a common issue. Handling methods: ① Small bubbles (diameter < 2mm) : No need for treatment. They usually dissipate automatically within 24 to 48 hours (the adhesive layer will flow and fill automatically). ② Large bubbles or bubbles in the middle of the screen: Use a scratch card (or wrap the bank card with a soft cloth) to gently push from the center of the bubble to the edge, driving the bubble to the edge and expexpel it. ③ Edge bubbles: Press the edge with your fingers to squeeze out the bubbles. If there is dust at the edge and the bubbles cannot be expelled, it may be necessary to reapply. ④ Dust spots causing bubbles (with a black dot at the center of the bubble) : These bubbles cannot be pushed out by pressure because the dust spots are stuck between the film and the screen, and the film needs to be re-applied - use a dust removal tape to stick away the dust and then re-apply it. Methods to prevent air bubbles: ① Thoroughly clean the screen before applying the film and use a dust-removing sticker to stick away all dust (check from the side under the light). ② Apply the film in a dust-free environment (such as a bathroom right after taking a bath, where water vapor settles the dust in the air); ③ Use a dust removal chamber (provided with Guanfudun) to reduce dust and alignment deviations caused by manual operation; When applying the film, slowly stick it from one side to the other. Do not apply it all over. Note: ① Do not poke the bubbles with a needle (it will damage the film and the screen); If there are too many bubbles or dust spots that cannot be dealt with, it is recommended to reapply the second piece (a 2-piece set costs 159 yuan and has a spare). Do not press the screen hard or play with the phone case within 24 hours after applying the film to ensure the adhesive layer adheres completely.
