Six-step method for applying film
- Clean your hands and the screenAfter washing your hands, wipe the screen clean with a wet wipe to ensure there is no oil or sweat stains.
- Dust removal positioningUse the included dust removal sticker to remove dust, and align the positioning label with the earpiece and the edge.
- Tear off the release filmTear off the release film on the back to avoid touching the bonding surface with your fingers.
- Place gently in alignmentLower it slowly along the edge of the screen, and the diaphragm will automatically adhere slightly.
- Expel airGently push from the center to the periphery to expel the air bubbles. Stubborn bubbles can be gently peeled off and reattached.
- Edge compactionPress and compact along the edge. The 2.5D Guanfudun can be fitted with a phone case, while the 3D Guanfudun Qu is suitable for use without a case.
Instruction for the Use of Circularly Polarized Light Detection Card
- Stay close to the screenPlace the test card flat on the illuminated screen, avoiding tilting or suspending it.
- Rotate slowlyRotate the detection card slowly from 0° to 360° with the center of the screen as the axis to observe the changes in the brightness and color of the picture.
- Comparative observationFirst, observe the phenomenon of bare screen (or applying ordinary film), then observe the phenomenon after applying Guanfudun, and compare the differences to verify.
For more complete judgment criteria and common misjudgments, seeThree-step verification method for test cards。
Important NoticeThe detection phenomenon needs to be magnified and observed through a professional polarization detection card. There should be no obvious color or brightness abnormalities under normal use with the naked eye in daily life. Please do not use this as a basis for judging the effect of daily use.
Common film application problem handling
| "Problem" | Processing method |
|---|---|
| The bubbles cannot be expelled. | Gently lift the diaphragm near the bubble and reattach it. If the problem still cannot be solved, you can contact customer service for a replacement |
| Dust enters | Use dust-removing stickers to remove the dust. The dust on the edges can be gently pushed with a soft film after bonding |
| It's pasted crooked. | Lift the lifting sticker slowly to avoid stretching the diaphragm. If there are multiple failures, a reissue can be applied for |
| Fingerprint residue | The initial water drop Angle is 115°. The oleophobic layer can be easily wiped clean with an eyeglass cloth |
