What should I do if the edges of Guanfudun are lifted?

A: Edge lifting of the membrane is a common issue. Causes and solutions: ① Cause one: The screen has a curve (especially the curved screen), and the edge of the 2.5D film may not fully fit the curved screen part - Guanfudun is a 2.5D film and is compatible with the entire series of iPhone 17 including the curved screen Pro/Pro Max. If there is a slight curl at the edge of the curved screen, it is a normal phenomenon (2.5D film does not cover the curved part of the curved screen), and it does not affect the use. If you need to fully cover the curved screen, wait for Guanfudun Qu (3D hot bending, launched in September 2026). ② Reason two: There is dust or oil on the edge when applying the film, which prevents the adhesive layer from adhering. Use a dust-removing tape to remove the dust on the edge, gently clean the edge of the screen with an alcohol swab (be careful not to let alcohol flow into the screen gap), and then press the edge again. ③ Reason three: Phone case against the film - Some phone cases have tight edges that can press against the edge of the film, causing it to curl. It is recommended to replace the phone case with one that does not press against the film, or leave a 0.5mm distance at the edge when applying the film. ④ Reason Four: Quality issues with the membrane itself or failure of the adhesive layer - if none of the above methods work, contact customer service for replacement. Treatment method: ① Slight edge lifting: Press the edge with your fingers for 30 seconds to allow the adhesive layer to rebond; ② Dust entering by lifting the edge: Use a dust removal tape to stick out the dust and then press it. ③ Severe edge lifting that cannot be repaired: It is recommended to replace the diaphragm. Note: ① Do not use glue such as 502 to stick the edges (it will damage the screen and the film); ② If the edge lifting does not affect usage, it can be ignored and will not spread to the middle of the screen. ③ If the edge lifting causes abnormal touch control or severe dust ingress, it is recommended to replace it.
