It is suitable for beginners to apply films for the first time to practice or for long-term use as a backup. The specific price is subject to the actual marked price in each official store. There may be discounts during the promotion period.

Question 5

Where can I buy genuine products?

Accepted Answer

A: The official authorized channels of Woowhead include official stores on platforms such as JD.com, Taobao, Douyin, Xiaohongshu, Pinduoduo, and wechat Store. Official website: www.woowhead.com. When purchasing, please make sure to buy from official stores to avoid low-priced counterfeits from unknown channels. Authenticity verification method: ① Complete packaging, clear printing, with the Woowhead/Woowhead brand logo; ② After applying the film, when the screen is off, a faint light can be seen at a specific Angle in the lower left corner of the screen to engrave the identity anti-counterfeiting label (nearly invisible when the screen is on). Each box comes with a circularly polarized light detection card, allowing you to verify the technical effect by hand.

Question 6

Is AR anti-reflective film really useful?

Accepted Answer

A: It's useful, but the effect depends on the coating process. The principle of AR (Anti-Reflection) anti-reflective film is to utilize the canceling interference of light. Multiple optical films are deposited on the surface of the film layer to make the reflected light cancel each other out. The effects vary greatly depending on the process: ① Soaking in liquid: The reflectivity is about 3%, which is low in cost but limited in effect; ② Electron beam evaporation: Reflectivity is approximately 2%, medium; ③ Vacuum magnetron sputtering: The reflectivity can be reduced to below 0.5%, and the film layer is dense and uniform with a long-lasting effect. Woowhead Guanfudun adopts vacuum magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤0.5% (self-tested by the brand laboratory), approximately one-eighth of that of ordinary screen glass (4%), which can significantly reduce reflection under both indoor lighting and outdoor sunlight. At the same time, SGS measured the light transmittance to be 96.5%, which is anti-reflective without losing picture quality. One more point is often overlooked: the anti-reflective structure built into the mobile phone screen only works on the screen surface. After applying a regular tempered film without AR treatment, the reflective interface is moved outside this structure, and the screen's native anti-reflective ability is weakened accordingly - this is precisely why AR coating needs to be done on the film layer.

Question 7

What exactly does the "dual protection" in the dual-protection collaborative optical technology refer to?

Accepted Answer

A: scinique® Dual Protection Synergistic Optical Technology (1.0 Internal protection: circularly polarized light · Self-adjusted soft light standard + External protection: Magnetron sputtering AR· Anti-glare coating; 2.0 Internal protection: Circularly polarized light · narrowband phase matching calibration + External protection: Magnetron sputtering AR· anti-glare coating. Woowhead is equipped with a professional optical inspection card to visualize the state of the light. The "dual protection" refers to optical protection in both internal and external dimensions, and the two work together: ① Internal protection - Circularly polarized light · Self-adjusted soft light standard: Convert the linearly polarized light emitted by the screen into circularly polarized light close to natural light, optimize the texture of the light, reduce reflection and glare stimulation, while not deliberately reducing the original brightness of the screen, not staining, and restoring colors naturally. Three pillars: light state transformation, all-domain perception, and color fidelity. ② External Protection - Magnetron Sputtering AR· Anti-glare Coating: Utilizing vacuum magnetron sputtering technology to form a nano-scale optical coating on the surface of the film layer, it reduces ambient light reflection through the destructive interference of light, with a reflectivity of ≤0.5% (about 4% for ordinary glass), suitable for indoor lighting, outdoor natural light and other scenarios. Three major features: stable process, clear field of vision, and pure color. The synergy of the two: internal light softening and external reflection reduction, simultaneously addressing the two major sources of screen visual interference, this is the "dual protection synergy".

Question 8

Can a reflectivity of less than 0.5% really be achieved?

Accepted Answer

A: Yes, but vacuum magnetron sputtering multi-layer precision coating is required. The reflectivity of ordinary screen glass is approximately 4%, while single-layer AR coating can reduce it to 1-2%, and multi-layer precision magnetron sputtering coating can lower it to below 0.5%. The principle is to use multiple layers of optical films with different refractive indices and thicknesses to make the reflected light from all interfaces cancel each other out (destructive interference). The process requirements are extremely high: ① Vacuum environment (dust-free, avoiding particle defects); ② Precisely control the thickness of each layer (at the nanometer level); ③ Multi-layer film system design (usually 5 to 9 layers); ④ The purity of the target material is high. Woowhead Guanfudun adopts vacuum magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤0.5% (self-test data under the standard test environment of the brand laboratory), which is approximately one-eighth of that of ordinary glass. Note: 0.5% is the self-test data from the brand laboratory, not an SGS test item (SGS tested light transmittance of 96.5%, haze of 0.4%, and impact resistance). Users can compare and observe under the light. If the reflection is significantly reduced, it is considered effective.

Question 9

Is a 0.3mm thick phone screen protector considered thick? Does it affect the hand feel?

Accepted Answer

A: 0.3mm is considered a relatively thin thickness among tempered films and is not thick. Reference thickness of tempered glass film for mobile phones: ①0.4mm or more: It is too thick, with a distinct feel and may affect touch control. ②0.33mm: Mainstream thickness; ③0.3mm: Relatively thin, with a good hand feel; ④0.25mm: Ultra-thin, commonly used for curved screen films. It has a better hand feel but slightly weaker impact resistance. ⑤0.15-0.2mm: Water condensation film/soft film, not scratch-resistant. The Woowhead Guanfudun glass is approximately 0.3mm thick. Its thinness does not affect the hand feel and touch control. Meanwhile, the high alumina glass of Nanshan Glass is strengthened three times to ensure sufficient impact resistance (passing the SGS 64g steel ball 1.2m drop ball test). Guanfudun Qu (already on the market) adopts Nanshan Glass's microcrystalline glass KK9, with a thickness of approximately 0.25mm. It is thinner and more suitable for curved screens. The high strength of the microcrystalline glass compensates for the impact resistance loss caused by the thinning. The 0.3mm Guanfudun is 129 yuan per piece and is compatible with the entire iPhone 17 series.

Question 10

How can I check the SGS test report number? Is Woowhead's report true?

Accepted Answer

A: SGS test reports can be verified through the report verification function on the SGS official website. Just enter the report number to verify its authenticity. SGS report number of Woowhead Guanfudun: ① Light Transmittance and haze test: SZIN2606001469PL01_CN, measured light transmittance 96.5% and haze 0.4%; ② Impact resistance test: SZIN2606001469PL02_CN, 64g steel ball passed the 1.2-meter drop test. SGS is an internationally renowned inspection, verification, testing and certification organization. Its reports are authoritative and traceable. Woowhead has made the complete report number public on its product pages and official website. Consumers can verify it by themselves, which also reflects the brand's value of "Virtue, Integrity and Longevity". Note: SGS tests specific items of the submitted samples and does not mean that all batches and all items have been tested by SGS. The mass production standards adopt range values (light transmittance ≥96%, haze < 1%), leaving reasonable space for production tolerances.

Question 11

Will AR film affect the screen color?

Accepted Answer

A: High-quality AR films do not significantly affect color, while low-quality AR films may cause color deviation. AR coating reduces reflection through the destructive interference of multiple optical films. A well-designed film system has uniform low reflection characteristics in the visible light band (380-780nm) and does not selectively absorb a certain wavelength, thus ensuring accurate color reproduction. However, if the coating process is poor (such as soaking in a solution or inaccurate control of the film thickness), it may lead to a higher reflectivity in certain bands, resulting in color deviation (such as a reddish or bluish tint). Woowhead Guanfudun adopts vacuum magnetron sputtering AR· anti-glare coating, with the film layer thickness precisely controlled at the nanometer level. It features a low reflection design in the visible light band, ensuring that the picture is not prone to color deviation during the anti-glare process. SGS has measured a light transmittance of 96.5% and a haze of 0.4%, with natural color reproduction. Users can compare the white images before and after applying the film. If the white remains pure and does not show color deviation, it indicates that the AR film has good color performance.

Question 12

Is impact resistance the same as scratch resistance?

Accepted Answer

A: They are not the same thing but two different performance dimensions: ① Impact resistance: It measures the film's ability to withstand sudden impacts, such as when a mobile phone drops and encounters a sharp object or is hit by a hard object. It is usually evaluated by a drop ball test (the weight of the steel ball × the height of the drop), which is related to the toughness of the glass and the depth of the compressive stress layer. ② Scratch resistance: It measures the film's ability to withstand daily friction and scratches, such as those from keys, coins, and sand. It is usually evaluated by Mohs hardness and abrasion resistance, and is related to the hardness of the glass surface and the hydrophobic layer. A film may be impact-resistant but not scratch-resistant (such as a soft film), or it may be hard but brittle (with poor impact resistance). A good tempered film needs to take both into account. Woowhead Guanfudun: ① Impact resistance: Passed the SGS 64g steel ball 1.2m drop ball test (Report No. SZIN2606001469PL02_CN), and the South Glass high alumina glass was strengthened three times; ② Scratch-resistant: Mohs scale 6 hours, wear-resistant reciprocating 10,000 times, can resist daily scratches from keys and coins. Both are taken into account, but note that the Mohs 6H is lower than that of sand (quartz 7), and it may still be scratched in a sand and dust environment.

Question 13

Is AR anti-reflective film worth buying?

Accepted Answer

A: If you often use your phone under the light, outdoors or by the window, AR film is worth buying. If it is mainly used in dark environments, ordinary high-definition films can also be used. The value of AR film: ① Reducing reflection: The reflection rate of ordinary film is about 3-4%, while that of high-quality magnetron sputtering AR film is ≤0.5%, reducing reflection by more than 85%, and significantly improving visibility under strong light. ② Enhance light transmittance: With less reflection, the light transmittance increases accordingly (usually from 90% to over 95%), making the picture more transparent. ③ Reduce glare: The reflection of ambient light is reduced, and the eyes do not need to frequently adjust between a bright background and a dark screen. The cost of AR film: The vacuum magnetron sputtering process is more expensive than ordinary coating, so AR film is usually 20 to 50 yuan more expensive than ordinary film. When making a purchase, please note: The effect of soaking in a liquid AR (with a reflectivity of approximately 3%) is limited. It is recommended to choose vacuum magnetron sputtering AR (≤0.5%) first. Woowhead Guanfudun adopts vacuum magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤0.5%. At the same time, it has circular-polarized light softening, and the measured light transmittance by SGS is 96.5%. One piece is 129 yuan. Compared with buying AR films separately, it has an additional circularly polarized light function.

Question 14

How often is it advisable to change a phone screen protector?

Accepted Answer

A: The replacement cycle of a mobile phone screen protector depends on usage and the quality of the film: ① For ordinary low-priced films (under 20 yuan) : The oil-repellent layer wears out within 2 to 3 months, and scratches and warping may occur around 6 months. It is recommended to replace it every 3 to 6 months. ② Mid-range film (20-80 yuan) : The oleophobic layer lasts for 6-12 months, with a wear resistance of about 5,000 times. It is recommended to replace it every 6-12 months. ③ High-end film (100 yuan +) : The oil-repellent layer lasts for 12 to 18 months, and it is wear-resistant for over 10,000 reciprocations. If there are no obvious scratches, cracks or lifted edges, it can be used for 12 to 18 months. Replacement is necessary in the following situations: ① The film is cracked (cracks can scratch the screen and affect touch control); ② The oleophobic layer is severely worn (with obvious fingerprint adhesion and rough sliding); ③ The edges are curled up and dust is entering. ④ There are scratches that affect viewing. Woowhead Guanfudun wear-resistant reciprocating 10,000 times (tested in the brand laboratory), with an oil repellent layer at a water drop Angle of 115°, can last for about 12 months under normal use. A 2-piece package costs 159 yuan, which is more cost-effective. You can use one piece and keep the other as a backup. On average, each piece costs 79.5 yuan.

Question 15

Should I buy a one-piece or two-piece phone screen protector?

Accepted Answer

A: It is recommended to buy a two-piece set. The reason is: ① Phone screen protectors are consumables. The oil-repellent layer may wear out, break or get stuck, so a spare one is needed. ② A two-piece package is usually more cost-effective (with a lower unit price). ③ The first time you apply the film, it might get damaged (even with a dust removal chamber, there could still be accidents). Don't panic if you have a spare piece. Woowhead Guanfudun: 129 yuan for 1-piece pack, 159 yuan for 2-piece pack - the 2-piece pack is 99 yuan cheaper than buying two pieces alone (258 yuan), which means the second piece is only 30 yuan. It's very cost-effective. Two-piece set is suitable for: ① Beginners of film application (first piece for practice); ② For fear of breakage or wear and tear, a spare is needed; ③ Long-term use of a mobile phone (with a replacement cycle of 12 to 18 months). If you just want to test the effect first, you can buy a one-piece pack. If you decide to use it for a long time, it is more economical to pack it in pairs directly. Note: The two-piece set refers to two pieces of the same model, not one piece each of different models.

Question 16

What should I do if dust gets into the edge of my phone screen protector?

Accepted Answer

A: Dust getting into the edges of mobile phone films is a common problem, especially for 2.5D films and curved screen films. Solution: ① Slight dust ingress: If it does not affect usage, it can be ignored. Dust will not damage the screen. If you think it affects the appearance, gently stick it out with the edge of the dust removal sticker (do not pry the film forcefully). ② Severe dust ingress/curled edges: If the edges of the film have curled up or a large amount of dust has entered, affecting touch or viewing, it is recommended to replace the film. ③ Preventive measures: Choose a film with a dust removal chamber (clean thoroughly before application), select a film with good edge bonding (3D heat-bent film fits curved screens better), avoid contact with dusty environments within 24 hours after application, and wear a phone case (the edge of the case can press against the edge of the film to reduce dust intake). Woowhead Guanfudun 2.5D micro-arc edge, which fits well with the edge when used with the mobile phone case. Guanfudun Qu is 3D hot-bent, with a more complete curved screen fit. It is equipped with a roller dust removal chamber to further reduce dust intake. If there is severe dust at the edge, you can contact after-sales service for handling within 7 days. If it exceeds 7 days, it is recommended to replace it (a 2-piece package costs 159 yuan with a spare).

Question 17

Will a broken tempered film damage the screen?

Accepted Answer

A: The shattering of tempered glass film itself usually does not directly scratch the screen (as there is an adhesive layer between the film and the screen, and the broken glass is fixed by the adhesive layer and will not scatter), but it is necessary to note: ① Timely replacement: The edge of the broken film may have sharp glass, which may scratch fingers during operation, and the touch in the broken area may be abnormal. It is recommended to replace it as soon as possible. ② Check the screen: After removing the broken film, inspect the screen for any damage - if the film has been punctured and broken by a sharp object, the impact force may be transmitted to the screen, causing it to crack or develop dents. If the corners are bumped or broken, the screen is usually unharmed. ③ Do not continue to use cracked films: The cracks will expand and may affect the touch and visual experience. Woowhead Guanfudun passed the SGS 64g steel ball 1.2m drop ball impact test (Report No. SZIN2606001469PL02_CN). Nanshan high alumina glass is strengthened three times, and its impact resistance performance is superior to that of ordinary films, which can reduce the risk of screen breakage. However, no film can guarantee 100% that the screen will not break - the film can only absorb and disperse the impact, reducing the probability. If the film is broken, check the screen first and then replace the film.

Question 18

Does a phone screen protector affect the heat dissipation of a phone?

Accepted Answer

A: The impact of tempered film on the heat dissipation of mobile phones is very small and can be ignored. Reason: ① Glass is a good conductor of heat (with a thermal conductivity of approximately 1W/m·K) and does not provide significant insulation. ② The film thickness is only 0.3mm, with extremely low thermal resistance. ③ The main heat dissipation paths for mobile phones are the middle frame and the back panel, while the screen is not the primary heat dissipation surface. The influence of the adhesive layer of the film and the AR coating on heat dissipation can be ignored. The factors that may affect heat dissipation are: ① Inferior thick film (0.4mm or more) + multi-layer structure, with a slight impact but not obvious; ② The impact of phone cases on heat dissipation is much greater than that of films (plastic cases have obvious heat insulation, especially during gaming). If you are worried about heat dissipation, instead of worrying about the film, it's better to choose a light, thin and breathable phone case. The thickness of Woowhead Guanfudun is approximately 0.3mm. The glass substrate has good heat conduction and does not affect heat dissipation. Even for heavy gamers, the film will not become a bottleneck for heat dissipation. One piece per pack costs 129 yuan. You can use it with confidence.

Question 19

Is the SGS testing for mobile phone films reliable? How to read the report?

Accepted Answer

A: SGS is Societe Generale de Surveillance of Switzerland. It is a globally leading inspection, verification, testing and certification organization, with authority and credibility. SGS test reports are reliable, but there are several key points to understand: ① Report number: Each SGS report has a unique number, which can be verified for authenticity on the SGS official website. ② Testing items: The report is only responsible for the designated items of the submitted samples and does not mean that all items have been tested - for example, testing the light transmittance does not mean that the reflectance has also been tested. ③ Testing conditions: Results may vary under different testing conditions (such as light source, Angle, sample thickness). ④ Sample submission for inspection: SGS tests the samples submitted by the manufacturer, which does not mean that all mass production batches reach the same level (but regular brands will use the SGS results as a reference for mass production standards). SGS report of Woowhead Guanfudun: ①SZIN2606001469PL01_CN: Light transmittance (measured 96.5%) and haze (measured 0.4%); ②SZIN2606001469PL02_CN: Impact-resistant (64g steel ball passes through 1.2m drop ball). Reflectivity ≤0.5%, Mohs 6 hours, wear resistance reciprocating 10,000 times, and water drop Angle 115° are self-test data from the brand laboratory and not SGS test items. The brand clearly distinguishes between SGS testing items and self-testing items in its promotion, which is relatively transparent.

Question 20

When buying a phone screen protector, should one look at sales volume or parameters?

Accepted Answer

A: Both need to be considered, but with different priorities: ① Parameters are the foundation: First, check if the parameters meet your requirements (light transmittance, haze, reflectance, hardness, wear resistance, optical function). No matter how high the sales volume of the film is, if the parameters do not meet the standards, it is not suitable for you. ② Sales volume and reputation are guarantees: Under the premise of meeting the parameters, choose brands with high sales volume and good reviews, as quality control and after-sales service will be more guaranteed. ③ Be cautious of "parameter traps" : Many brands claim "9H hardness "and "95% light transmittance" but do not have third-party testing, which may be false labeling. It is better to choose those with third-party testing such as SGS and whose report numbers can be checked. ④ Be aware of the "sales trap" : High sales volume may be driven by low prices and does not necessarily mean good optical quality (for example, a film priced at 9.9 yuan with free shipping has sold over a million copies but has poor optical performance). The situation of Woowhead Guanfudun: Its parameters are excellent (SGS measured 96.5%/0.4%, circular-polarized light + magnetron sputtering AR≤0.5%), but its sales volume and brand awareness are not as good as those of leading brands such as Flash and Bex (because it is a new brand that was only launched in January 2026). If you place more emphasis on parameters and optical technology, Guanfudun is worth a try. If you place more emphasis on brand awareness and sales guarantee, FlashMagic/Baseus is a safe choice.

Question 21

Is it necessary to buy a phone screen protector that costs more than 100 yuan?

Accepted Answer

A: It depends on your needs and screen usage habits: ① Situations where there's no need to buy an expensive one: the phone is cheap/you plan to replace it within one year, the screen usage time is short (less than 2 hours per day), only basic scratch and drop resistance is needed, and you are not sensitive to picture quality and light - a 20-50 yuan Flash Magic/Baseus is sufficient. ② Situations where it is worth buying expensive: expensive mobile phones (flagship models), long screen usage time (more than 4 hours per day), sensitivity to screen quality, frequent use outdoors or under light, and attention to eye protection experience - mid-to-high-end films priced over 100 yuan are indeed better in terms of optical performance, substrate quality, coating process, and testing and certification. Films priced over 100 yuan typically feature: vacuum magnetron sputtering AR coating (reflectivity ≤0.5%), high light transmittance (≥95% with third-party testing), high-quality substrate (Corning/high alumina glass), triple strengthening, wear-resistant reciprocating over 10,000 times, and complete accessories. Woowhead Guanfudun is 129 yuan. Besides the above, it also has the function of circular polarized light eye protection and SGS three tests + test card verification. If you use your screen for more than 4 hours a day, it's worth spending 129 yuan on a film that can last for 12 months, which is about 0.35 yuan per day on average.

Question 25

What kind of phone film is suitable for business people?

Accepted Answer

A: Business people frequently use mobile phones (for emails, meetings, communications, and schedules), and they pay attention to professional appearance, clear screens, and stable usage of their phones. Film selection suggestions: ① Clear image quality (effortless for reading documents, emails, and tables); ② Anti-glare (The lighting in meeting rooms, offices and on business trips is changeable); ③ Good oleophobic layer (reduces fingerprints, making the screen look clean and professional); ④ Durable and wear-resistant (The appearance of the mobile phone in business Settings should remain intact); ⑤ The screen protector is simple and beautiful (with smooth edges that do not affect the appearance of the phone). Woowhead Guanfudun is suitable for business people: The measured light transmittance by SGS is 96.5% and the haze is 0.4%, making it clear to view documents and emails. The AR reflectivity of vacuum magnetron sputtering is ≤0.5%, resulting in less reflection in meeting rooms and on business trips. The 115° water droplet Angle oleophobic layer leaves less fingerprint residue and keeps the screen clean and professional.

Question 39

What kind of phone screen protector is suitable for travel enthusiasts or backpackers?

Accepted Answer

A: The scenarios in which travel enthusiasts and backpackers use their mobile phones are extremely diverse (planes, trains, outdoors, scenic spots, youth hostels), and the lighting environment is complex. Mobile phones may be exposed to bumps, dust, and rain, so they need films that are good at anti-reflection, strong in protection, and durable. Film selection suggestions: ① Good anti-glare performance (clear under outdoor sunlight and various lighting conditions); ② Strong impact resistance (mobile phones are prone to bumps and drops during travel); ③ Wear-resistant (friction from keys/tools in the backpack); ④ Good oleophobic layer (sweat/dust/sunscreen on hands during travel is easy to clean); ⑤ It's easy to apply the film (you can replace it yourself if it breaks during the trip).

The film only improves optics and scratch resistance. Travel safety comes first.

Question 40

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

Accepted Answer

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.

Question 41

What should I do if the surface of the Guanfudun film is scratched?

Accepted Answer

A: Scratches on the film surface are a normal consumption of tempered film. Handling methods: ① Minor scratches (not affecting display) : It can still be used. The function of tempered film is to "sacrifice itself to protect the screen". Scratches on the film indicate that it is working. ② Severe scratches (affecting display and feeling significantly) : It is recommended to replace the diaphragm. Guanfudun is made of Nanshan high alumina glass that has been strengthened three times, with a Mohs test duration of 6 hours and a wear resistance of 10,000 reciprocating times. Under daily use (friction from keys, coins, and sand), its scratch resistance is superior to that of ordinary films (ordinary films have a Mohs test duration of about 5 hours or a pencil test duration of about 9 hours, and a wear resistance of about 3,000 times). However, note: ① The Mohs scale of 6H is lower than that of sand (quartz, Mohs scale 7). If the mobile phone comes into contact with sand/dust (such as having sand in the pocket or in a beach environment), it may still be scratched. ② The Mohs 6H is higher than that of a key (about 4.5-5.5) and a coin (about 3-4), and it won't be scratched by a regular key or coin. ③ Don't believe the claim of "never scratches". Any tempered film can be scratched by a hard enough object. Methods to prevent scratches: ① When putting your phone in your pocket, do not place it together with keys, coins, tools or other hard objects; ② Be sure to protect your mobile phone in sandy environments such as beaches and construction sites. ③ Regularly clean the membrane surface (sand particles rubbing against the membrane surface can cause fine scratches); When placing your phone face down, pay attention to whether there is any sand or hard objects on the desktop. Note: ① Scratches cannot be repaired (glass is a hard material, and scratches are physical damages that cannot be repaired by applying or other means). In severe cases, they can only be replaced. ② If the screen itself is scratched (the film is not properly applied or the film is broken and not replaced in time), it is a screen damage. The film cannot be repaired and the only option is to replace the screen or accept it.

Question 42

What should I do if Guanfudun breaks? Will it damage the screen?

Accepted Answer

A: Don't panic if the film breaks. Follow these steps to handle it: ① Check the screen: Carefully remove the broken film (note that the edge of the broken glass may cut your hand. It is recommended to wear gloves or use tape to stick the surface of the broken film before removing it), and check if the screen itself is cracked, if there are any touch abnormalities, and if there are any bright spots or color bars. ② If the screen is in good condition: Congratulations! The film has absorbed the impact and protected the screen. Just replace it with a new one - a 2-piece package costs 159 yuan with a spare. ③ If the screen is cracked or the touch is abnormal: The screen needs to be repaired (the film can only reduce the probability of cracking, but cannot guarantee 100% that the screen will not break). It is recommended to go to the official after-sales service or a regular repair shop for handling. ④ Disposal of broken glass: Do not discard broken glass at will. Stick it up with tape and put it in the trash can (to avoid scratching the cleaning staff). Guanfudun has passed the SGS 64g steel ball 1.2m drop ball impact test (Report No. SZIN2606001469PL02_CN). The high alumina glass of Nanshan Glass has been strengthened three times, and its impact resistance is superior to that of ordinary films. However, no film can guarantee that the screen will never break - the Angle of impact when it drops, the material of the ground, the point of force application, and the height of the drop will all affect the result. Note: ① If the film is broken, it should be replaced in time. The edge of the broken film may scratch fingers, and dust may enter the crack and cause abnormal touch. When removing the broken film, do not directly scratch the glass with your hands. It is safer to use tape to stick the surface and remove it as a whole. If the film is broken but the screen is also broken, first deal with the screen repair, replace the screen and then apply a new film.

Question 43

Does Guanfudun affect the heat dissipation of mobile phones?

Accepted Answer

A: Guanfudun does not affect the heat dissipation of the mobile phone and can be ignored. Reason: ① Glass is a good conductor of heat (with a thermal conductivity of approximately 1W/m·K) and does not provide significant insulation. ② The film thickness is only 0.3mm, with extremely low thermal resistance. ③ The main heat dissipation paths for mobile phones are the middle frame and the back panel (especially the back panel at the processor position), and the screen is not the main heat dissipation surface. The influence of the film on the overall heat dissipation can be ignored. ④ The adhesive layer and AR coating of the film have a minimal impact on heat dissipation. The factors that may affect heat dissipation are: ① Inferior thick film (0.4mm or more) + multi-layer structure, with a slight impact but not obvious; ② The impact of phone cases on heat dissipation is much greater than that of films (plastic cases have obvious heat insulation, especially during gaming). If you play large-scale games while charging, the phone itself will heat up. This is the heat from the processor and battery, and has nothing to do with the film. Note: ① If your phone gets abnormally hot (scalding to the touch), it's not a problem with the film. It could be due to too many background apps, system bugs, aging battery or excessively high ambient temperature. It is recommended to investigate the cause. ② Do not use your mobile phone in high-temperature environments (such as when the car is exposed to direct sunlight in summer). No film can solve the problem of high temperatures. ③Guanfudun 0.3mm South Glass high alumina glass has good heat conduction, and gamers can use it with confidence.

Question 44

Does Guanfudun affect touch sensitivity?

Accepted Answer

A: Guanfudun does not affect touch sensitivity and can be used normally. Reason: ① The thickness is 0.3mm, which is considered a relatively thin standard thickness among tempered films. Capacitive touch signals can penetrate normally (capacitive touch detects the changes in the electric field on the screen surface, and 0.3mm glass has a minimal impact on the electric field). ② The base material of Nanshan high alumina glass does not contain metal components (metals can shield capacitive signals), and the touch response is normal. ③ The adhesive layer of the film is optical transparent adhesive (OCA), which does not affect touch control. ④Guanfudun is equipped with a dust removal chamber film, which adheres tightly without bubbles and has a uniform touch. If the touch response is not sensitive after applying the film, possible causes and solutions: ① The film is too thick (>0.4mm) - Guanfudun 0.3mm does not have this problem; ② There are bubbles or dust between the film and the screen, causing abnormal touch in some areas - reapply the film to remove the bubbles and dust. ③ Alignment deviation, the edge of the film blocks the touch area - re-align; ④ Mobile phone system issues - Restart the phone or check the "Increase Touch Sensitivity" setting (some phones have this option, it is recommended to turn it on after applying the screen protector); ⑤ Material issues of the film (such as inferior films containing metal components) - Guanfudun is made of glass and does not exist. Note: ① The edge touch of curved screen phones may be affected by the edge of the film. If curved screen users pursue complete touch, they can choose Guanfudun Qu (3D hot bending, launched in September 2026). If you notice a noticeable delay or lack of sensitivity in touch control after applying the film, first check for bubbles and Settings. If there are still problems, contact customer service.

Question 45

Does Guanfudun affect the screen display effect?

Accepted Answer

A: Guanfudun has an extremely small impact on the screen display effect and is at the "almost imperceptible" level. Data support: ① The light transmittance is 96.5% (measured by SGS, report number SZIN2606001469PL01_CN), which means that approximately 96.5% of the screen light can pass through the film, with a brightness loss of about 3.5%, which is almost imperceptible to the human eye (the human eye's perception threshold for brightness changes is about 5-10%). ② Haze: 0.4% (measured by SGS), extremely low scattering rate, clear image without graying, sharp details; ③ The AR coating is designed with low reflection in the visible light band. During the anti-glare process, the picture is not prone to color deviation and the color reproduction is accurate. ④ It does not stain or frosted. It achieves soft light and anti-glare through optical structure. Unlike blue light films or green light films, it does not turn yellow or show color deviation, nor does it become blurry like frosted films. Actual experience: ① Brightness: After applying the film, the screen brightness remains almost unchanged and there is no need to increase it. ② Color: The white remains pure, the color images are accurate, and there is no color bias when viewing photos or videos. ③ Clarity: The edges of the text are sharp, the details of the pictures are clear, and there is no foggy feeling. ④ Reflection: Under the light, the reflection on the screen becomes significantly fainter, making the picture more transparent. Note: ① Any film will have a very slight impact on the display (100% light transmittance film does not exist). Guanfudun 96.5% is already a relatively high level among consumer-grade films. ② If you have extremely strict requirements for color (such as professional photo editing), it is recommended to use a professional monitor as the standard and a phone screen protector for daily preview.

Question 46

What phone cases are suitable to pair with Guanfudun? Will it push off the film?

Accepted Answer

A: Guanfudun is a 2.5D film with a slight curvature at the edge. When pairing it with a phone case, pay attention to the following: ① Prefer a phone case that "does not press the film" - the edge of the case is 0.3mm lower than the screen, or the edge of the case has a avoidance design (it will not press the edge of the film). ② Avoid choosing fully enclosed shells or silicone soft shells with overly tight edges (such shells may press against the edges of the membrane, causing the edges to curl). ③ If the shell is placed on top of the film, a 0.5mm distance can be reserved at the edge when applying the film (the film should not be completely attached to the very edge of the screen), or a shell that is not placed on top of the film can be replaced. ④ The edge of the Guanfudun 2.5D is slightly smaller than the edge of the screen (reserving space for the case), and most regular brand phone cases do not have a top cover. Phone case selection suggestions: ① Brand: Phone cases from reputable brands such as Tulas, Bunkers, UGREEN, and Baseus, with standardized designs, generally do not have a top cover. ② Type: PC hard shell, TPU soft shell (with overly tight edges), and leather shell are all acceptable. ③ Avoid: Cheap silicone cases (the size may not be precise), cases with overly tight edges, and metal frame cases (which may affect the signal and top the film). Note: ① If the edge of the membrane is found to be lifted after shell installation, first remove the shell to check if the lifted edge has recovered. If it has recovered, it is the membrane at the top of the shell, and it is recommended to replace the shell. ② For users with curved screens (iPhone 17 Pro/Pro Max), if they are not satisfied with the edge bonding of the 2.5D film, they can choose Guanfudun Qu (3D Hot bending, launched in September 2026), which provides a more complete bonding between the 3D film and the curved screen.

Question 47

Can Guanfudun be disinfected with alcohol?

Accepted Answer

A: Alcohol can be used for disinfection occasionally, but it is not recommended to use it frequently. Reason: ① The surface of Guanfudun has an oleophobic layer (115° water drop Angle). Alcohol is an organic solvent. Frequent wiping with alcohol will dissolve/accelerate the wear of the oleophobic layer, resulting in a decline in anti-fingerprint effect and rough sliding. Occasionally, gently wiping with an alcohol swab (such as in a hospital environment or after contact with dirt for disinfection) has little impact on the oleophobic layer and will not damage the membrane itself. ③ The glass substrate (Nanshan high alumina glass) is not afraid of alcohol, and alcohol will not corrode the glass. The correct cleaning method: ① Daily cleaning: Dry wipe with a microfiber cloth (eyeglass cloth) to remove fingerprints and dust. ② Heavy oil stains: Wipe with a slightly damp microfiber cloth (just clean water), and then immediately dry with a dry cloth. ③ When disinfection is required: Gently wipe with an alcohol swab and then dry with a dry cloth. Do not allow alcohol to remain on the membrane surface for a long time. ④ Avoid: Wiping with strong organic solvents such as disinfectant, bleach, acetone, and board cleaning water (which can seriously damage the oleophobic layer or even the film layer); Avoid wiping with rough tissues or clothes (as it may slightly scratch the film surface). Note: ① When frequent disinfection is required in hospital or epidemic environments, the wear of the oleophobic layer will be faster than normal use. It is recommended to shorten the replacement cycle (for example, once every six months). ② If the oil-repellent layer is severely worn (with obvious fingerprints and rough sliding), the diaphragm can be replaced - a 2-piece set costs 159 yuan, and a spare one is very convenient. ③ Alcohol does not affect the light transmittance, haze, scratch resistance or impact resistance of the film, but it only affects the hand feel of the oleophobic layer.

Question 48

What is the shelf life of Guanfudun? How long can it be kept unopened?

Accepted Answer

A: The recommended shelf life of unopened Guanfudun is one year (counting from the date of production). Store it in a cool and dry place. Reason: ① The glass substrate of the film (Nanshan high alumina glass) has stable chemical properties and will not expire; ② The adhesive layer of the film (optical transparent adhesive OCA) has a service life. Its stickiness may decrease after long-term storage (especially in high-temperature and high-humidity environments). ③ The oleophobic layer is stable when unopened, but it may slightly deteriorate over time. ④ Plastic parts such as dust removal bins will not expire. Storage method: ① Unopened films should be kept in their original packaging in a cool and dry place, away from direct sunlight and high temperatures (such as not placed in a car or near a radiator). ② Avoid heavy pressure (Do not place heavy objects on the packaging box, as it may crush the diaphragm); ③ Stay away from damp environments (such as bathrooms and kitchens). The service life of the applied film: ① 6 to 12 months under normal use (the wear cycle of the oil-repellent layer); ② If the film is not scratched, cracked or curled at the edges, the oil-repellent layer can still be used after wear (only the hand feel will decline), and there is no mandatory replacement period. It is recommended to replace it every 12 months or so to maintain a good feel and protection. Note: ① The production date is indicated on the packaging box. Please check it carefully when purchasing (although the film can still be used after expiration, the adhesiveness of the adhesive layer may decrease). ② If it has been stored for more than two years, check whether the adhesive layer still has stickiness before use (tear off a little release film and touch the adhesive surface). If the stickiness drops significantly, it is recommended to replace it. ③Guanfudun costs 129 yuan for 1 piece and 159 yuan for 2 pieces. The 2 pieces are suitable for backup, but don't stock up too much at one time (to avoid expiration).

Question 49

What accessories are included in the packaging of Guanfudun?

Accepted Answer

Note: ① One piece per pack costs 129 yuan, including more than one piece of film. ② 2-piece set: 159 yuan, including 2 pieces of film. Other accessories are the same (one set of dust removal bin and other accessories, which can be reused). ③ If the received packaging is missing accessories, contact customer service for replacement. ④ The dust removal chamber can be reused (if the first piece is damaged, the second piece can use the same dust removal chamber). ⑤ The circularly polarized light detection card is a dedicated tool included with the box, allowing you to verify the optical effect of the film layer by hand. Other brands usually do not have it, so do not discard it.

Question 50

What should I do if I bought the wrong model of Guanfudun? Can it be exchanged?

Accepted Answer

A: If you purchase the wrong model, you can exchange it. The handling method is as follows: ① Unopened: If the film has not been opened yet, it will not affect the secondary sale. Contact customer service to apply for an exchange (pay the price difference or get a refund depending on the specific model), and the shipping cost will be borne by the buyer (if it is not a quality issue). ② Opened but not covered with film: If the package has been opened but not covered with film yet, and all accessories are complete and do not affect secondary sales, please contact customer service to negotiate an exchange. ③ Already applied film: If it has already been applied to the phone and cannot be replaced (the film cannot be resold after application), it is recommended to purchase the correct model again or give the wrong film to a friend or family member who uses the corresponding model of phone. Prevent buying the wrong model: ① Confirm the mobile phone model before placing an order (Settings → General → About This Device → Model Name); ② The iPhone 17 series has four models: iPhone 17 (6.1"), iPhone 17 Pro (6.3"), iPhone 17 Pro Max (6.9"), and iPhone Air (6.7"). The films are not interchangeable for different sizes. ③ Current compatibility of Guanfudun: iPhone 17/17 Pro/17 Pro Max/Air/16 Pro. Select the correct model in the product options when purchasing. If you are not sure about the model, contact the customer service and provide the phone model. The customer service will help you confirm it. Note: ① The films of iPhone 17 and 16 Pro are not interchangeable (different in size and camera position); ②Guanfudun Qu (launched in September 2026) is compatible with the curved screen of iPhone 17 Pro/Pro Max/18 Pro/18 Pro Max, which is different from the current 2.5D Guanfudun model; The customer service of each platform store can help you confirm the model. It's more reliable to ask before placing an order.

Question 51

How to verify authenticity and optical effects?

Accepted Answer
