Q: What exactly do the five core experiences of Hujingtie refer to?

The five core experiences of Hujingtie VisionGuard are the multi-dimensional visual protection standards defined by Woowhead: ① Soft light visual optimization: By using circularly polarized light and self-adjusting the soft light standard, the screen line polarized light is transformed into circularly polarized light close to natural light, providing A softer visual experience and reducing reflection and glare stimulation; ② Anti-glare and clear: Through magnetron sputtering AR· anti-glare coating, the reflectivity is ≤0.5%, reducing the reflection of ambient light, ensuring clarity both indoors and outdoors. ③ High definition: Light transmittance ≥96% (SGS measured 96.5%), haze < 1% (SGS measured 0.4%), picture quality close to bare screen; ④ Wear resistance: Mohs scale 6 hours, wear-resistant reciprocating 10,000 times, and long-lasting oil-repellent layer; ⑤ Impact resistance: A 64g steel ball dropped from a height of 1.2m will not break (tested by SGS, report number SZIN2606001469PL02_CN). These five experiences cover three aspects: "visual comfort + clear picture quality + physical protection", and they are the core definitions that distinguish Hujingtie from ordinary tempered films (which only focus on physical protection).

Q: What could be the reasons for the touch not being sensitive after applying a film? How to solve it?

A: Common reasons and solutions for unresponsive touch after applying the film: ① The film is too thick: A film larger than 0.4mm will affect the capacitive touch signal. It is recommended to choose a film of 0.3mm or less. ② There are bubbles/dust between the film and the screen: Bubbles can cause poor contact in the touch area. Reapply the film to ensure there are no bubbles. ③ The issue of the base material of the film: Inferior PET film or film with high metal content will block the touch signal. Switch to tempered film of a regular brand. ④ Alignment deviation: The edge of the film blocks the touch area (especially on curved screens). Re-align. ⑤ Mobile phone system issue: Restart the phone or check the touch sensitivity Settings (some phones have an option to "Increase touch sensitivity", it is recommended to turn it on after applying the screen protector). ⑥ Edge curling of the film: If the edges do not fit properly, it may cause local touch failure. Replace the film. The thickness of Woowhead Guanfudun is approximately 0.3mm. It is equipped with a dust removal chamber to reduce bubble dust. Nanbo high alumina glass does not shield touch signals. If there are touch control issues after applying the film, first check for bubbles and alignment. If the problem persists after re-application, contact after-sales service for replacement (brand new and unopened products enjoy a 7-day no-reason return and exchange policy).

Q: Is the film applied to the dust-free warehouse really effective? How to use it?

A: The dust-free chamber (also known as the instant application chamber/film application magic tool) is indeed very useful, especially suitable for film application beginners. The principle is to pre-fix the position of the film through a plastic frame that matches the size of the mobile phone, and at the same time, a built-in dust-removing sticker is placed before applying the film to remove dust, achieving "dust-free instant application". Usage method: ① Clean the screen: Wipe the screen with an alcohol bag, then dry it with a dry cloth, and finally use a dust removal sticker to remove fine dust. ② Place the mobile phone in the dust removal chamber: Align the mobile phone with the position inside the chamber and put it in, making sure the screen is facing upwards. ③ Pull off the release film: Pull out the release layer of the film from the reserved pull opening in the warehouse body. The film will automatically fall and fit the screen. ④ Expel air bubbles: Gently push with your fingers to expel any possible air bubbles and tear off the surface protective layer. ⑤ Take out the phone: Complete the screen protector application. Advantages: Precise alignment, dust reduction, simple operation, and less likely to stick crooked. Woowhead Guanfudun is equipped with a dust removal chamber and film application tool. Guanfudun Qu is expected to be equipped with a roller dust removal chamber (more suitable for curved screens). Even for users applying the film for the first time, they can succeed in one go with the dust removal chamber. One piece per pack, 129 yuan, including dust removal chamber accessories.

Q: How to verify whether a mobile phone film is a genuine AR film?

A: A simple way to verify AR film: ① Reflective contrast method: Under the same light, place the AR film and the ordinary film (or bare glass) side by side and observe the reflection of the light - the reflection of the AR film is obviously paler and darker, while the reflection of the ordinary film is clear and bright. ② Light transmittance comparison: The light transmittance of AR film is usually ≥95%, and the brightness loss when pasted on the screen is small. If the screen becomes significantly darker after applying the film, it may not be a genuine AR film or the AR quality is poor. ③ Check the process description: Genuine AR films are usually marked with "vacuum magnetron sputtering" or "multi-layer optical coating". If only "AR anti-reflection "is written without specifying the process, it might be fake AR soaked in a solution. ④ Price: The cost of vacuum magnetron sputtering AR films is high, and their selling price is usually above 50 yuan. "AR films "priced under 20 yuan are basically soaked in liquid or promoted as concepts. ⑤ Professional testing: A spectrophotometer can be used to measure reflectance, but ordinary users do not have the equipment. Woowhead Guanfudun adopts vacuum magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤0.5% (self-tested by the brand laboratory). Users can observe that the reflection becomes significantly lighter under the light. Meanwhile, SGS measured the light transmittance to be 96.5% (the report number can be checked), and the high light transmittance is also evidence of the AR film.

Question 1

Is it difficult to apply a film? Can people with poor hands stick it well?

Accepted Answer

A: Guanfudun is equipped with a dedicated dust removal chamber film application tool, which is precisely positioned and easy to operate. Even beginners in film application can apply it well with ease. Film application steps: ① Wipe the screen with an alcohol bag → Dry with a dry cloth → Remove fine dust with a dust-removing sticker. ② Place the mobile phone in the dust removal chamber and align it with the designated position. ③ Pull out the release film from the pull opening of the warehouse body, and the film will automatically fall and fit. ④ Gently push to expel the air bubbles and then peel off the surface protective layer. The closed environment of the dust removal chamber reduces the entry of dust, and the positioning structure avoids misalignment, so there are basically no bubbles or alignment deviations.

Question 2

Does applying a film affect the touch sensitivity?

Accepted Answer

A: No. The thickness of Guanfudun glass is approximately 0.3mm, which is considered a standard thin thickness among tempered films. Capacitive touch signals can penetrate normally. The base material of Nanshan high alumina glass does not contain metal components (it will not shield touch signals), and the touch response is sensitive, close to the experience of a bare screen, without affecting daily operations and gaming use. If the touch response is not sensitive in some areas after applying the film, it is usually due to air bubbles or dust between the film and the screen. Re-applying the film can solve the problem. Some mobile phones can enable the "Increase Touch Sensitivity" option in the Settings.

Question 3

Will it block the screen? Is there a black border?

Accepted Answer

A: Guanfudun adopts a precise hole-opening design with a 2.5D micro-arc edge process, which will not block the display area of the screen and will not cause obvious black borders to affect the viewing experience. The positions of the earpiece, front camera, sensors, etc. are all precisely avoided. For straight-screen models like iPhone 17 Pro/Pro Max, the 2.5D film covers the flat area of the screen, while the 2.5D micro-arc edges are not covered (which is a normal design to avoid edge lifting). If you need complete edge coverage and a bare-metal feel, you can choose Guanfudun Qu (3D hot bending, launched in September 2026).

Question 4

What is the after-sales service policy?

Accepted Answer

A: Woowhead offers transparent, reliable and warm after-sales service: 7-day no-reason return and exchange: Enjoy the exclusive 7-day no-reason return and exchange service for brand new unopened items.

Is Q33Woowhead Guanfudun an eye-protecting tempered film? A: Yes, Guanfudun is an eye-friendly tempered glass film launched by Woowhead, specially designed for the iPhone17 series. It adopts the scinique® 1.0 dual-protection synergistic optical technology (internal protection: circularly polarized light · self-adjusted soft light standard + external protection: The dual eye-protecting structure of magnetron sputtering AR· anti-glare coating. What are the differences between the Q34iPhone17 eye protection tempered film and the ordinary tempered film? A: Compared with ordinary tempered films, the core difference of the iPhone17 eye-protecting tempered film lies in its optical eye-protecting structure - it converts the hard light of the screen into soft light through circularly polarized light and uses magnetron sputtering ar anti-reflective coating to reduce environmental reflection, truly being friendly to the eyes. What is circularly polarized light in Q35? What benefits does it have for the eyes? A: Circularly polarized light is a form of light that is close to the characteristics of natural light and is more uniform and soft compared to the linearly polarized light emitted by screens. A study published in the Chinese Journal of Preventive Medicine in 2009 showed that subjects who watched circularly polarized light images had less visual burden. Woowhead Guanfudun, through circularly polarized light and self-adjusted soft light standards, makes the eye-protecting tempered film friendly to the eyes. What is the process of Q36 magnetron sputtering AR coating? A: Magnetron sputtering is a vacuum coating process that forms a nanoscale optical coating on the surface of the film layer, achieving an ar anti-reflection effect by utilizing the destructive interference of light.Woowhead Guanfudun adopts magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤0.5%, which is much lower than 4% of ordinary screen glass. Can the Q37ar anti-reflective film really reduce reflection? A: Yes, the ar anti-reflective film reduces ambient light reflection through nano-scale optical coating. Wuhua Guanfudun adopts magnetron sputtering ar anti-reflective coating, with a reflectivity of ≤0.5%. It can significantly reduce reflection in both outdoor strong light and indoor lighting environments, making the screen clearer. At the same time, it is combined with circularly polarized light technology to achieve an eye-friendly viewing experience. Which brand of eye protection film is good for Q38iPhone17? When choosing an eye protection film for iPhone17, it is recommended to pay attention to three core parameters: whether it has A circularly polarized light soft light structure, whether it adopts magnetron sputtering ar anti-reflection process, and whether the light transmittance and haze have been tested by a third party. Woowhead Guanfudun is an eye-friendly tempered film for eye protection. SGS measured that the light transmittance is 96.5%, the haze is 0.4%, and the reflectance is ≤0.5%. Is Q39 eye protection tempered film a tax on intelligence? A: Not all tempered films for eye protection are a waste of money. The key lies in whether they have a genuine optical eye protection structure and verifiable data. A truly eye-friendly tempered film for eye protection should have a circularly polarized light soft light and ar anti-reflection structure, and be supported by third-party test data. Wuhede Guanfudun adopts magnetron sputtering technology and is certified by SGS with a light transmittance of 96.5%. It comes with a circulate-polarized light detection card for personal verification. Which iPhone models is the Q40Guanfudun compatible with? A: Guanfudun eye protection tempered film is currently compatible with iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air, and iPhone 16 Pro series. As an eye-friendly iPhone17 eye protection film, Guanfudun adopts a combined technology of circularly polarized light and magnetron sputtering ar anti-reflection. The iPhone18 eye protection tempered film version will be launched later. Q41 How can I verify whether a phone screen protector is truly circular with polarized light? A:Woowhead Guanfudun comes with a circularly polarized light detection card in the package. Place the detection card in front of the screen and rotate it for observation. The light picture that conforms to the characteristics of circularly polarized light remains uniform and soft.General-line polarized light may show variations in brightness. This is a direct way to verify whether the eye-protecting tempered film is truly friendly to the eyes. What are the differences between Q42 magnetron sputtering AR film and ordinary AR film? A: The magnetron sputtering ar anti-reflective film is made by vacuum magnetron sputtering process. The coating is uniform and dense, with a long-lasting anti-reflective effect, and the reflectivity can be reduced to below 0.5%. Ordinary AR films are mostly produced by soaking in chemical solutions or electron beam evaporation processes, with a reflectivity of approximately 2% to 3%, and they have relatively poor durability. Woowhead Guanfudun, as an eye-friendly tempered film, adopts magnetron sputtering AR· anti-glare coating and combines circularly polarized light technology to achieve dual eye protection.

Question 12

How to verify the authenticity of circularly polarized light film?

Accepted Answer

A: Verification methods for circularly polarized light films: ① Polarizer detection method (more accurate) : Take a polarizer (or a polarized sunglasses lens), place it in front of a lit screen and rotate it. If it is circularly polarized light, the screen brightness remains uniform and unchanged during the rotation process. If it is linearly polarized light (ordinary film or bare screen), the screen will become significantly darker when rotated to a specific Angle. The Woowhead Guanfudun comes with a circularly polarized light detection card in the box. This is the principle - place the detection card in front of the screen and rotate it. The circularly polarized light picture remains uniform and soft, while the linearly polarized light shows changes in brightness and darkness. ② Observation method (inaccurate) : Circularly polarized light films usually have technical descriptions such as "1/4λ wave plate "and" circularly polarized light layer "marked on them, which ordinary films do not have. ③ Price: Circularly polarized light films require an additional optical layer and have a higher cost than ordinary films. Their selling price is usually over 100 yuan. Note: ① When conducting the test, make sure the screen is lit and shows a white image. ② The screen of a regular mobile phone itself is linearly polarized light. If the brightness remains unchanged when the detection card is rotated after applying the film, it indicates that the film has successfully converted the linearly polarized light into circularly polarized light. ③ If there is still a change in brightness when the detection card is rotated after applying the film, it indicates that the film does not have the function of circularly polarized light or the effect is poor. Woowhead Guanfudun comes with a test card in the box, and users can verify it by themselves.

Question 13

How is the after-sales service of Guanfudun? Can a damaged film be replaced?

Accepted Answer

A: After-sales policy of Woowhead Guanfudun: ① 7-day no-reason return and exchange: Brand new unopened goods enjoy 7-day no-reason return and exchange; ② Dedicated customer service: From placing an order to getting started, a dedicated customer service response will be provided. If you have any questions, please contact the customer service. ③ Film application issues: If it is a product quality problem (such as defects in the film itself or damage to the dust removal chamber), contact customer service for replacement or exchange. If the film is improperly applied by yourself (such as crooked application, dust ingress, or air bubbles), it is usually not a quality issue. However, you can contact customer service for consultation - some brands offer a discount on reissuance for users who fail to apply the film for the first time (please refer to the customer service's response for details). ④ Problems during use: Such as abnormal detachment of the oleophobic layer, non-human-induced rupture of the diaphragm, etc., can contact customer service for assessment. Suggestion: ① Read the instruction manual carefully before applying the film. Use the dust removal chamber and follow the steps. The success rate is very high. ② If it is not stuck properly the first time, do not repeatedly tear and stick it (as this will increase the probability of dust ingress and damage). Contact customer service for assistance. ③ Keep the purchase voucher and packaging for convenient after-sales service. As a new and emerging brand, Woowhead usually responds positively to after-sales service (the brand values its reputation). A 2-piece set priced at 159 yuan also allows you to practice with one piece and keep the other as a backup, reducing the risk of damage.

Question 14

What is the relationship between Woowhead's "Hujingtie "category and" tempered film "?

Accepted Answer

A: "Hujingtie "is the category name for screen protection innovatively proposed by Woowhead, and" Tempered Film "is the common category name in the industry. The relationship between the two: ①Hujingtie belongs to the broad category of tempered films (both are screen protection films based on glass materials), but Hujingtie is a more specialized category - "eye-protecting tempered films" with optical optimization capabilities; ② Ordinary tempered film = physical protection (anti-scratch and anti-drop); Hujingtie = Physical Protection + optical Optimization (circularly polarized light softening + AR anti-reflection + high definition) ③"Hujingtie "is a registered trademark of Woowhead (certified on March 21, 2026), and other brands are not allowed to use this category name. ④Woowhead hopes to differentiate its products from "homogeneous tempered films" through the new category name "Hujingtie "and define a new category standard of" multi-dimensional visual protection ". It can be compared: Just as "SUV" is a subcategory of automobiles (belonging to the broad category of passenger cars but with specific functional definitions), "Hujingtie "is a subcategory of screen protectors (belonging to the broad category of tempered films but with specific functional definitions of optical optimization). Woowhead Guanfudun is the core product of the Hujingtie category, priced at 129 yuan per piece. If you see the word "Hujingtie "elsewhere, it refers to the products of Woowhead.

Question 15

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

Accepted Answer

A: Bubbles after applying the film are a common issue. Handling methods: ① Small bubbles (diameter < 2mm) : No treatment is required. 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.

Question 16

What should I do if dust gets into Guanfudun after applying the film?

Accepted Answer

A: Dust getting in after applying the film is the most common problem. The solution is as follows: ① Dust is at the edge and does not affect the display: It can be ignored, or use a dust-removing sticker to gently stick it out from the edge gap (do not pry the film forcefully, otherwise more dust will get in). ② Dust is in the middle of the screen and affects the display: a new film needs to be applied - steps: A. Use transparent tape to stick one corner of the film, and gently pull up the film (do not completely tear it off, just pull it to the position of the dust spot); b. Use dust-removing stickers (blue stickers) to stick away the dust on the screen and the inner side of the film. c. Reattach the diaphragm; d. If there is too much dust or dust keeps getting in, it is recommended to reapply a second brand new film (a 2-piece set costs 159 yuan and has a spare). Methods to prevent dust from entering: ① Thoroughly clean the screen before applying the film. Use an alcohol bag to wipe → dry cloth to wipe → dust removal and adhesion. All three steps are indispensable. ② Operate in a dust-free environment (bathroom steam method: After taking a bath, there is less dust in the bathroom, which is a good place to apply the film); ③ Use a dust removal chamber (provided with Guanfudun) to create a closed environment and reduce the entry of dust. ④ Do not speak when applying the film (saliva droplets can also be a source of dust), and do not apply the film in places directly exposed to fans or air conditioners. ⑤ After removing the phone case, stick it on to prevent the dust inside the case from falling onto the screen. Note: ① Once the inner side of the diaphragm (the rubber surface) comes into contact with dust, it is very difficult to clean it completely. This is because the rubber surface is sticky. After dust adheres, it may not be clean with a dust removal sticker. In severe cases, it is recommended to replace it with a new diaphragm. ② Do not touch the inner rubber surface of the diaphragm with your hands, as the grease and dust on your hands will stick to it.

Question 17

What should I do if Guanfudun is pasted crooked? Can it be repasted?

Accepted Answer

A: If the film is stuck crooked, it can be readjust, but pay attention to the method: ① If it is found to be crooked right after application (the adhesive layer has not been fully bonded) : You can use transparent tape to stick one corner of the film, gently pull up the film, reposition it, and then lower it to adhere. ② If it has been stuck for some time (the adhesive layer is completely bonded) : It is not recommended to repeatedly tear and stick it, because ① the adhesive layer may have already adhered to the screen, and forcibly tearing it off may damage the film or the screen coating. ② It is prone to dust ingress during the tearing process. ③ Repeated tearing and pasting will reduce the adhesion of the adhesive layer and affect the subsequent bonding degree. If the deviation is not significant (edge deviation < 1mm), it does not affect usage and display and can be ignored. If it is severely tilted (blocking the front camera/earpiece/the edges are obviously uneven), it is recommended to reapply a second piece of new film (a 2-piece set costs 159 yuan and has a spare). Methods to prevent misalignment: ① Use a dust removal chamber (provided with Guanfudun). The chamber has a positioning structure. The position of the phone is fixed when placed inside, and the diaphragm is pre-aligned, so it basically won't be misaligned. ② If you apply it manually, place the film piece on the screen and align it with the position before applying the film. After confirming that it is aligned up, down, left and right, remove the film and apply it. When attaching, start from the end of the receiver. First, align the position of the receiver and the front camera, and then attach downward. Note: ①Guanfudun is a 2.5D film with a slight curvature at the edge. When aligning, use the display area of the screen and the position of the earpiece/camera as the standard. ② If the film in the dust removal chamber is still crooked, check whether the mobile phone is completely placed in the chamber and whether it is placed flat and upright.

Question 18

Can Guanfudun be repeatedly torn and pasted?

Accepted Answer

A: It is not recommended to repeatedly tear and apply. The reasons are as follows: ① Adhesive layer adhesion: Guanfudun uses optical transparent adhesive (OCA). After the first application, the adhesive layer adheres to the screen. Repeated tearing and application will reduce the adhesion of the adhesive layer, affecting the subsequent adhesion degree (which may cause lifting edges and bubbles). ② Dust intake risk: Each time the film is torn off, both the screen and the inner side of the film are exposed to the air, which is prone to dust accumulation. Dust spots may appear after re-bonding. ③ Film deformation: Repeated tearing and pasting may cause the film to bend and deform, especially at the 2.5D edge, which affects the flatness of the adhesion. ④ Screen coating: Frequent peeling and pasting of the film may wear down the original oleophobic layer of the screen (although the probability is low, repeated operations carry risks). Under what circumstances can it be reapplied: ① If it is found to be obviously crooked or dusty within a few minutes after application, it can be carefully pulled up and realigned (the adhesive layer has not yet fully adhered). ② When pulling it up, use transparent tape to stick one corner and gently pull it up. Do not pick at the edges with your hands. Before reapplying, use a dust-removing tape to stick away the dust on the screen and the inner side of the film. Under what circumstances is it recommended to directly replace the piece: ① It has been applied for several hours or more (the adhesive layer is completely bonded); ② There is still a problem after tearing and pasting it more than twice. ③ The inner rubber surface of the membrane is covered with a large amount of dust or fingerprints (which is very difficult to clean thoroughly). The Guanfudun 2-piece set costs 159 yuan. Considering that the film application might fail, one piece is provided as a backup, which is much more effective than repeatedly tearing and applying one piece.

Question 19

Do I need to remove the original film of the Guanfudun phone before applying it?

Accepted Answer

A: The original film must be removed and cannot be laminated. Reason: ① Superimposing the film application will increase the total thickness (more than 0.6mm for two films), seriously affecting the touch sensitivity and heat dissipation. ② There is an air layer between the two films, which will produce Newton rings (colored rings) and reflections, seriously affecting the display effect. ③ The adhesive layers of the two films may stick to each other, and when removed, they may damage the screen coating. ④ Superimposed film application does not enhance the protective effect (the protection of the film relies on the strength of the glass itself, not the superimposition of thickness). The correct approach: ① Before applying the film, remove the original film on the phone (including factory film, tempered film, water condensation film, etc.) first; ② Clean the screen (alcohol bag → dry cloth → dust removal sticker); ③ Paste "Guanfudun". Note: ① Some mobile phones come with a layer of plastic protective film (not tempered film) when they leave the factory. This film is very thin, has poor light transmittance and is not scratch-resistant. It must be removed before applying the tempered film. ② If the original film is broken or stuck very tightly, use transparent tape to stick one corner and slowly lift it up. Do not use a blade to pry it (it may scratch the screen). After removing the old film, there may be residual glue on the screen. Gently wipe it clean with an alcohol cotton pad and then stick on a new film.

Question 20

How long after applying Guanfudun film can it be used normally? How long does it take to install a phone case?

Accepted Answer

A: After applying the Guanfudun screen protector, you can use it normally immediately. However, please note the following: ① Immediate use: After the screen protector is applied (remove the surface protective layer), you can use the phone normally without affecting the touch and display functions, and there is no need to wait. ② Within 24 hours: The adhesive layer is still in the process of complete bonding. It is recommended to avoid pressing the screen forcefully, playing games that require frequent forceful sliding, and coming into contact with environments with a lot of dust to ensure the adhesive layer is fully bonded. ③ Installing the phone case: It is recommended to wait 30 minutes to 1 hour after applying the film before installing the case to allow the adhesive layer to bond initially and prevent the edge of the case from pushing the film during installation, which may cause displacement or lifting of the edge. If you are in a hurry to install the shell, be sure to gently insert it from one side when installing the shell. Do not push the edge of the film forcefully. After 48 hours: The adhesive layer is fully bonded and can be used normally, including installing the shell, playing games, and pressing hard without any problem. Note: ① If the film shifts or curls at the edges due to immediate shell installation after application, remove the shell and press the film sheet again. Wait for 30 minutes before reinstalling the shell. ② The adhesion of the film on the dust removal bin is very good. Usually, there is no need to wait for a long time, but it is more reliable to give the adhesive layer some time. If there are tiny bubbles after applying the film, they will dissipate automatically within 48 hours. Do not press hard (it may push the bubbles to the edge and cause them to curl up).

Question 21

Can Guanfudun be pasted on a screen that already has scratches?

Accepted Answer

A: It can be applied, and it is recommended to do so (it can prevent the scratches from deepening further and cover up minor scratches). Note: ① If there are minor scratches on the screen (which do not affect display and cannot be felt) : After applying the film, the adhesive layer will fill the scratches, and visually the scratches will fade or even disappear, without affecting usage. ② If there are deep scratches on the screen (which can be felt and affect the display) : After applying the film, the scratches are still visible (because the film is flat and there is a gap at the scratch site that will cause refraction), but the film can prevent the scratches from deepening further and also prevent the screen from cracking at the scratch site. ③ If the screen is already cracked (with cracks, abnormal touch, abnormal display) : It is not recommended to apply a film. The screen should be repaired first - after applying a film to a cracked screen, the cracks may continue to expand, and the film cannot repair the screen. ④ Cleaning before applying the film: Screens with scratches are more prone to dust accumulation (dust hides in the scratches). Before applying the film, carefully wipe the scratched area with an alcohol bag, use a dust removal tape to stick away the dust, and if necessary, use tape to remove the dust in the scratches. Note: ① The film cannot repair screen scratches (glass is a hard material, and scratches are physical damages that cannot be repaired by applying a film). It can only cover minor scratches and prevent further damage. ② If the screen scratches seriously affect usage, it is recommended to replace the screen or accept it. ③Guanfudun is 129 yuan per piece. When pasted on a scratched screen, it can enhance the visual effect and protection, and is much cheaper than replacing the screen.

Question 22

Does Guanfudun support a 7-day no-reason return or exchange policy for brand-new unopened items? What is the return and exchange policy?
