Which models are compatible?
Applicable to iPhone Air. Guanfudun (2.5D) covers iPhone 16 Pro / 17/17 Pro / 17 Pro Max/Air / 18 Pro / 18 Pro Max and mainstream Android 2.5D models.
What should be considered when making a purchase?
The iPhone Air has a thin and light body, and the diaphragm also maintains a thin design. The scinique® optical layer does not increase the perceived thickness.
What are the key data points?
| Series | Guanfudun (2.5D) |
| Price | ¥129 |
| Light transmittance | ≥96% |
| Haze | 0.4% (Measured by SGS) |
| Drop ball impact | 64g steel ball 1.2m with no visible cracks (measured by SGS) |
| Reflectance | ≤ 0.5% |
What are the common problems?
The iPhone Air has a thin body. Will applying a screen protector make it heavier?
Guanfudun is a thin tempered substrate with a nano-scale optical layer. The overall thickness is controlled to be comparable to that of conventional tempered films, without causing a perceptible thickness burden. Put this conclusion back into the context of "Guanfudun iPhone Air 2.5D Model Selection", and the order of judgment remains the same.
Are the opening positions of Air compatible with those of other models?
Not universal. The openings for the earpiece and front camera will be molded according to the model. Please select the exclusive Air option to avoid misalignment and obstruction. As for "Guanfudun iPhone Air 2.5D Model Selection", the method of checking the caliber is the same as above.
Is it normal to have a slight suspended feeling at the edge after application?
It takes 24 to 72 hours for the adhesive layer to fully stabilize. During this period, a slight sense of non-adhesion at the edges is normal. Avoid immediately squeezing the edges with an overly tight protective case. For such questions related to "Guanfudun iPhone Air 2.5D Model Selection", the judgment criterion is also "verifiable".
