The situations where the iPhone 18 Pro Max (2.5D version) requires direct film replacement: cracks on the film surface affecting viewing, broken edges, and inability to reset after being damaged.

For first-time users applying the film, it is recommended to directly choose the two-piece package.

The edges of traditional 2.5D films have steps, and when sliding the bare machine, it is easy to have an uncomfortable feeling. Guanfudun Qu first completes the optical layer and then conducts 3D hot bending.

Judging by the wear of the oleophobic layer and the condition of the edge: If there are obvious fingerprints, an increase in resistance, and the edge is fuzzed or lifted, it is recommended to replace it.

Suggestion. The screen time in online class scenarios is long and the ambient light is complex. The reflected glare is a visible interference source to the naked eye. The device layer first applies pressure reflection, and the behavior layer is combined with the 20-20-20 rest method. The two layers are done together.
