Folding screens mark with a fingernail. The makers' warranties exclude scratches and wear
Labs in the UK and Germany, and the makers' own handling guides, say a folding phone's inner screen is soft enough to be marked by a fingernail or a grain of sand. Apple, Samsung and Google's warranties, in every country checked, exclude scratches, cosmetic damage, wear and external causes.
The short answer
The inner screen on a folding phone is soft. Apple, Samsung and Google each say so in their own handling guides, which tell owners to keep sand, grit, keys, coins and fingernails away from it, and two independent labs have measured it: Which? scores foldable screens 1.3 out of 5 for scratch resistance against 5 for a glass phone, and Stiftung Warentest has recorded the same film as “kratzempfindlich”, scratch-sensitive, across three generations of Samsung’s folding phones.
The same three makers’ warranties, in the United States, the United Kingdom, Germany, France, Australia, Canada, Japan and India, exclude scratches, cosmetic damage, normal wear, protective coatings that wear down, and damage from accident, misuse or any external cause. Google’s adds “exposure to sharp objects” and “exposure to excessive force”. Those are the ways a soft screen fails in a pocket.
An inner screen costs about half the phone to replace out of warranty: £999 on an iPhone Duo in the UK, $999 in the United States, A$1,749 in Australia, 182,800 yen in Japan. The care plans that cut that to a fixed fee are sold separately and exclude cosmetic damage too. In the UK, the EU and Australia the law gives an owner a route that does not depend on the warranty; in the United States it mostly does not.
Where this comes from
Published documents only. The warranties, care-plan terms, handling guides and repair estimates are Apple’s, Samsung’s and Google’s own pages for the United States, the United Kingdom, Germany, France, Australia, Canada, Japan and India, plus Motorola’s razr guide. The durability figures are Which?’s, Stiftung Warentest’s, CNET’s and JerryRigEverything’s own reports. The failure record comes from Samsung’s and Motorola’s statements, a federal court docket, a Bar and Bench report of an Indian consumer commission order, and the press. The panel history comes from Apple’s specification pages and launch releases, DisplayMate’s shoot-outs, Samsung Display’s and Google’s own pages, and the Korean trade press. The law is quoted from the statutes. All pages were current on 25 October 2026. No company was asked for comment.
What I found
The panel, model by model
Apple’s specification pages for every OLED iPhone since 2017 never use the words “flexible”, “plastic”, “LTPO” or the name of a supplier. Those facts come from the lab that measured each generation and from the Korean trade press, and they are consistent. For the iPhone X, DisplayMate described “a state-of-the-art OLED display that is manufactured on a flexible plastic substrate”, adding that “While the OLED display itself is flexible, the screen remains rigid under an outer hard cover glass.” It repeated both sentences, word for word, in its shoot-outs of the XS Max, 11 Pro Max, 12 Pro Max, 13 Pro Max and 14 Pro Max, changing only “cover glass” to “Ceramic Shield cover glass” from 2020. Samsung Display, which made every iPhone X panel and most since, describes the type on its technology page: “Flexible OLED is a flexible panel completed by applying flexible PI substrate”, PI being polyimide, a plastic. That substrate is the one thing that has not changed. Almost everything above and below it has:
- iPhone X, 2017. “all-screen OLED Multi-Touch display”, 625 cd/m2 (Apple). First OLED iPhone. The panel “curves around behind itself” at the bottom edge (BGR). Samsung Display the only supplier (DisplayMate). Apple’s own “LT” emitter material set (The Elec).
- XS and XS Max, 2018. Same line. LG Display approved as a second supplier (The Korea Herald, via 9to5Mac). The XR is LCD.
- 11 Pro, 2019. “Super Retina XDR”, 800 nits. Apple “started using the M series in 2019”, Samsung Display’s standard material sets (The Elec). The 11 is LCD.
- 12 family, 2020. “Ceramic Shield front” (Apple). Cover “tougher than any smartphone glass” (Apple). All four models OLED, still at “the standard 60 Hz Refresh Rate” (DisplayMate).
- 13 Pro, 2021. “Super Retina XDR display with ProMotion”, “adaptive refresh rates up to 120Hz” (Apple). A new backplane: Samsung’s “low-temperature polycrystalline oxide (LTPO)” panels for the Pro pair, LG’s LTPS for the 13 and mini (The Elec via 9to5Mac). Apple: “from 10Hz to 120Hz”, “a more efficient OLED panel” (Apple). M11 materials (The Elec).
- 14 Pro, 2022. “Always-On display”, 2000 nits outdoor (Apple). Still ProMotion at up to 120 Hz, and the panel can now drop to 1 Hz when idle: Apple says the Always-On display is “enabled by a new 1Hz refresh rate and multiple power-efficient technologies” (Apple). M12 materials (The Elec).
- 15 Pro and 16 Pro, 2023 and 2024. Same lines; “1 nit minimum brightness” from the 16. M12 then M14 materials; LTPO stays Pro-only (The Elec, ETNews).
- 17 family, 2025. ProMotion on every model, 3000 nits, “Anti-reflective coating”, “Ceramic Shield 2 front” (Apple). LTPO across the line: “all equipped with LTPO AMOLED displays”, Samsung 57 million panels, LG 30 million, BOE 1.3 million (UBI Research via OLED-Info). Apple: “adjusts down to 1Hz”, “3x better scratch resistance” (Apple).
- 18 Pro, 2026. Same lines as the 17 Pro. “LTPO+” reported, Samsung and LG only (ETNews and The Elec, via 9to5Mac and iClarified).
- iPhone Duo, 2026. “all-screen OLED folding display”, “Wide-angle OLEDs”, “Under-display FaceTime camera”, same ProMotion and brightness lines (Apple). A polymer cover layer instead of Ceramic Shield on the inner screen; “10 ultrathin layers” (MacRumors). Trade reports: Samsung Display sole supplier for three years, a polariser-free “CoE” stack, and the M14 material set (The Elec, April); ETNews, via Tom’s Guide in February, said M16. The reports conflict and Apple says neither.
So the part that bends in the Duo is not a new kind of panel. It is a flexible OLED on polyimide, the construction the X carried in 2017, nine generations on: a faster backplane, four material sets, twice the brightness, a different driver, and built to a folding specification rather than a flat one. On the slab phones the layer above that panel moved one way, from glass to Ceramic Shield in 2020 to Ceramic Shield 2 in 2025, harder each time. On the folding phones it went the other way, and every maker has spent seven years trying to claw it back:
- Galaxy Fold, 2019. A polyimide cover film. Samsung: “a new polymer layer” and “a display around 50 percent thinner than the typical smartphone display” (Samsung). After the review units failed, the film was extended under the bezel.
- Galaxy Z Flip, 2020. Glass “only 30㎛” thick, under a protective layer, replacing “our existing polyimide cover window” (Samsung Display).
- Z Fold3 and Flip3, 2021. “a new protective film made of stretchable PET and optimized display panel layers resulting in a Main Screen that’s 80% more durable”, and 120 Hz (Samsung). Samsung’s own support page on the change: “The current film material is still prone to deformation” (Samsung UK).
- Flip6, 2024. Glass “increased in thickness by 60%” (Samsung).
- Fold7, 2025. A “Titanium plate layer” and glass “increased to be 50% thicker” (Samsung); the panel passes 500,000 folds (Samsung Display).
- Fold8, 2026. “Flex Titanium”: a titanium-alloy film with “20 times greater mechanical stiffness” than the polymer film it replaces, over a titanium plate (Samsung); 3,000 nits.
- Pixel Fold to Pixel 11 Pro Fold, 2023 to 2026. Google’s spec page: “Ultra Thin Glass with protective plastic layer” on the first, “Ultra Thin Glass” and 3,600 nits on the latest (Google); “two layers of anti-impact film” on the 10 Pro Fold and a “thicker glass layer” on the 11 Pro Fold (Google).
- iPhone Duo, 2026. “a nano-textured cover layer — made from a custom polymer with up to 40 percent higher stiffness than other materials used in the industry”, “High-strength glass … above and below the folding display panel”, sliding adhesives, “a titanium plate at the bottom” (Apple). On top of all of them is a soft film; Samsung’s is “Thermoplastic Poly Urethane, commonly abbreviated as TPU. It is a flexible/soft material” (Samsung United States).
Thicker glass, tougher film, stiffer plate, every year. And every year’s inner screen still marks at Mohs level 2.
What the makers say the screen cannot take
In their own guides:
- Apple, iPhone User Guide: the cover layer “is an integral part of the inner display … don’t attempt to remove it”; “Applying an external screen protector can compromise the display performance”; “keep sand and grit away from the hinge”; “Folding hard objects such as keys or coins inside iPhone Duo can damage the inner display.”
- Samsung, UK support: the film “is a consumable product. If a certain period has elapsed scratches, bubbles, and lifting may occur on the protective film due to normal wear.” Avoid “folding the screen with foreign objects such as cards, keys, sand, metal powder etc.” and “Pressing the screen with various objects such as pens, nails, keys”. An impact on the thin glass “is likely to cause a crack or break, which can spread to the surrounding areas resulting in the appearance of a white line while folding the device.”
- Google, Pixel 11 Pro Fold safety guide: “Flexible screens are softer than traditional phone screens, so avoid contact with sand, crumbs, fingernails and sharp objects. Ensure there are no objects or fine particles (such as sand or dirt) on the foldable display or in the display hinge when closing it. Do not remove or peel back the pre-installed screen protector, as it can cause damage. Do not apply a third party screen protector.”
- Motorola, razr 2024 user guide: “Don’t replace the screen protector in service centers that Motorola doesn’t authorize or try to remove or replace the screen protector yourself. This may damage the main screen and void the warranty.”
Sand, grit, crumbs, keys, coins, pens, fingernails. That is the contents of a pocket.
What the labs measured
Which? has tested 59 folding phones since 2020. On the things people fear they did well: 58 passed 30,000 machine folds and every one survived 100 drops from 80 cm. On scratch resistance, scored one to five with glass phones “usually” at five, “They score a dismal 1.3 on average”, and “the screen can be permanently marked by something as simple as a firm fingernail – damage a normal phone would shrug off without a second thought.”
Stiftung Warentest, the German consumer testing body, has said the same three times. In November 2019 its Galaxy Fold survived 37,000 folds and “Das Display hielt stand”, the display held. In October 2023 the Fold5 and Flip5 hinges passed 30,000 folds “problemlos”, but “Die Displays sind aber nach wie vor kratzempfindlicher als die klassischer Smartphones, etwa gegenüber Fingernägeln”: the displays remain more scratch-sensitive than a conventional phone’s, for instance to fingernails. In September 2024 the Fold6 took 50,000 folds, and of the Flip6: “Leider war die innere Displayfolie sehr kratzempfindlich”, unfortunately the inner display film was very scratch-sensitive.
The Mohs hardness tests run by the YouTube channel JerryRigEverything put a number on it. On the iPhone Duo, in a video published 23 October 2026, “The outer screen with Ceramic Shield 2 scratched at level 7 on the Mohs scale, but the inner screen only managed level 2”, as MacRumors summarised it. Level 2 is a fingernail. The same channel’s tests of the Galaxy Z Fold8 and the Pixel 11 Pro Fold report the same level for their inner screens. One lab, one channel and one magazine, three countries, one result.
On folding itself the record is better. Samsung has said since 2019 that its panels pass a 200,000-fold test, now 500,000, verified by Bureau Veritas. CNET’s fold robot stopped the first Galaxy Fold in 2019 after “119,380 folds left the hinge damaged and half the screen blacked out”, which CNET put at “around three years of use”. Which? and Stiftung Warentest found hinges pass. The weakness is not the fold count. It is the surface.
What has failed, since 2019
- April 2019, Galaxy Fold review units, United States. The Verge: “a small bulge right on the crease” that broke the screen, “no obvious proximate cause”. CNBC’s unit failed with the film untouched. Response: Samsung, 17 April: the top layer “is part of the display structure”; removing it “may cause damage” (statement, via The Verge). 22 April: launch delayed; failures “could be associated with impact on the top and bottom exposed areas of the hinge” and “substances found inside the device” (Samsung). July: film extended under the bezel, hinge caps added (Samsung).
- February 2020, Motorola razr, United States. Input: the display “peeling at the fold” after a week, never dropped. Response: Motorola: “We have full confidence in razr’s display, and do not expect consumers to experience display peeling as a result of normal use”; weather-related failure “during normal use” would be “covered under our standard warranty” (Input).
- February 2020, Galaxy Z Flip, United States. iFixit’s teardown: “The top layer is indeed plastic”, glass beneath (iFixit). Response: Samsung said the phone “has a protective layer on top of the UTG” and “should be handled with care”.
- February 2023, Galaxy Z Fold3, United States, Australia. TechSpot: cracks at the fold; “Virtually all of the users say these problems were not caused by accidental drops, impact damage, or heavy-handedness.” One owner quoted $700 for a repair after Samsung “claims to have found an impact point”, “something the owner insists never happened”. Response: No Samsung statement found.
- December 2022 to April 2024, Galaxy Z Fold3, United States, federal court. Lewis v. Samsung Electronics America, S.D.N.Y. 1:22-cv-10882: the complaint alleged the phone was sold on a 200,000-fold claim while screens cracked at the fold, and that Samsung “shifts blame to user error or misuse”. Response: Samsung’s motion to compel arbitration was granted in November 2023; the case was voluntarily dismissed in April 2024. No court ruled on the screen. The complaint is allegation, not finding.
- June 2023, Pixel Fold, United States. Ars Technica: “The flexible OLED screen died after four days.” The reviewer’s diagnosis: debris in the gap between film and bezel, crushed when the phone closed. Response: Google told The Verge: “We recommend anyone having an issue reach out to support to investigate.”
- July 2026, Galaxy Z Flip3, India, Kolkata consumer commission. Bar and Bench: “a black shadow appeared near the fold” seven months in; the service centre “demanded Rs 29,849 for repairs, terming the damage ‘accidental and liquid damage’”. The commission ordered Samsung “to either replace the handset or refund Rs 85,000, along with Rs 25,000 as compensation and Rs 10,000 towards litigation costs”, and said Samsung “has not explained why an external impact that supposedly cracked the body would require replacement of the internal OCTA display”. Response: One order, one phone, as Bar and Bench reported it.
- October 2026, iPhone Duo, Australia, United States, Canada, China. MacRumors, Tom’s Guide, Notebookcheck: owner photos of inner screens failing along the hinge within a day of sale, one after “fewer than 20” openings. Every outlet says the count and cause are unknown. Response: Apple Stores replaced phones. No Apple statement found by 25 October.
There is no published regulator action on a folding screen, no free inner-screen repair programme from any maker, and no published failure rate for any model. What the record shows is narrower and still worth stating: in every year since the category launched, in the United States, Europe, India and Australia, owners and reviewers have reported inner screens failing at the fold with no impact they could identify, and the makers’ answers have been that the layer must stay on, the hinge must stay clean, and the damage was external.
What the warranties exclude
The limited hardware warranties, by maker, in their own words. The exclusions are the same in substance everywhere; the duration is not.
- Apple (United States, UK, Germany, France, Australia, Canada, Japan). One year, everywhere. Excluded: “(a) to consumable parts, such as batteries or protective coatings that are designed to diminish over time …; (b) to cosmetic damage, including but not limited to scratches, dents …; (d) to damage caused by accident, abuse, misuse, fire, liquid contact, earthquake or other external cause; (e) to damage caused by operating the Apple Product outside Apple’s published guidelines; … (h) to defects caused by normal wear and tear”. The United States, Australian and Canadian texts add: “Apple is not responsible for damage arising from failure to follow instructions relating to the Apple Product’s use.”
- Samsung (United States, UK, Germany, Australia, India). 12 months in the United States and India; 24 months in the UK, Germany and Australia. Excluded, United States: “(a) Defects or damage caused by accident, misuse, abnormal use …; (c) Scratches, dents, and cosmetic damage; (d) Defects or damage caused by pressing on a touch screen with excessive force or with an object not approved by Samsung …; (f) Ordinary wear and tear”. UK: “If your device has a smashed or cracked screen, this will be deemed out of warranty. If the device has deep scratches or dents that cause the device not to operate, this would also be classed as out of warranty” (Samsung UK). India: “Warranty does not cover normal wear and tear (including, without limitation, wear and tear of camera lenses, batteries or displays).”
- Google (United States and Canada, UK and EEA, Australia and New Zealand). One year in the United States and Canada; two years in the UK, EEA, Australia and New Zealand. Excluded: “does not apply to any consumable parts, such as batteries or protective coatings, that due to their nature diminish over time … nor to any cosmetic damage … does not apply to damage caused by: (1) normal wear and tear; (2) accidents; (3) misuse (including failure to follow product documentation); … (8) external causes such as, but not limited to: liquid damage, exposure to sharp objects, exposure to excessive force”.
Set the two lists side by side. The guides say the screen is damaged by fingernails, sand, keys and coins. The warranties exclude scratches, cosmetic damage, wear, external causes, sharp objects, excessive force and not following the guide. None of the three warranties mentions a folding screen, a film or a cover layer by name; the only clause that reaches the film is the one on “protective coatings that are designed to diminish over time”. The one maker that puts the question beyond doubt is Motorola, whose guide says removing the film yourself “may damage the main screen and void the warranty”.
Germany is the exception worth knowing about. Samsung Germany’s film page says the film is replaced free four times in the first 24 months, “insgesamt viermal kostenlos”, and that “Durch das Abziehen der Folie erlischt nicht die Garantie”, removing the film does not end the warranty, though damage caused by removing it is the owner’s to pay (Samsung Germany). In the United States it is one free film in the first year and $19.99 after that (Samsung United States); in the UK, “a free one-time replacement”.
The paid plans do not fill the gap either. AppleCare+ in the UK excludes “cosmetic damage … including, but not limited to, hairline cracks, scratches, dents, tears, bubbling, peeling” (AppleCare+ UK terms) and in the United States covers only damage “resulting from an unexpected and unintentional external event (such as, drops and damage caused by liquid contact)” (AppleCare+ United States terms). Samsung Care+ in the UK excludes “cosmetic damage and wear and tear … scratched screen or dented casing” (Samsung Care+ UK terms). Google’s Pixel Care+ gives free screen repairs on its phones with a footnote: “not available for inner screens of Pixel Fold phones” (Pixel Care+).
What the repair costs, against the phone
Apple’s own out-of-warranty estimates for the iPhone Duo on 25 October 2026, with the phone’s starting price from Apple’s store in each country. Apple also prices the cover layer alone and “Other damage” in each: $49 and $1,499 in the United States, £49 and £1,499 in the UK, 55 EUR and 1,719 EUR in Germany and France, A$79 and A$2,619 in Australia, C$69 and C$2,249 in Canada, 8,800 yen and 273,800 yen in Japan, Rs 5,900 and Rs 224,900 in India.
| Country | Phone from | Inner display | With AppleCare+ |
|---|---|---|---|
| United States | $1,999 | $999 | $99 |
| United Kingdom | £1,999 | £999 | £79 |
| Germany | 2,299 EUR | 1,149 EUR | 99 EUR |
| France | 2,339 EUR | 1,149 EUR | 99 EUR |
| Australia | A$3,499 | A$1,749 | A$149 |
| Canada | C$2,999 | C$1,499 | C$129 |
| Japan | 364,800 yen | 182,800 yen | 12,900 yen |
| India | Rs 299,900 | Rs 149,900 | Rs 8,900 |
In every country the inner display is half the phone. AppleCare+ for the Duo is $16.49 a month in the United States and £13.99 a month or £169.99 a year in the UK (AppleCare+ UK pricing). Each Apple page adds: “We’ll need to inspect your product to provide a personalised estimate.”
Samsung’s United States repair page prices a Galaxy Z Fold8 inner screen at $579 as a module with frame and battery, or $419 as a screen-only repair, against a launch price of $1,899.99; the Fold8 Ultra is $639 or $479, the Flip8 $359 or $249. Samsung India’s spare part price list puts the Fold8’s main screen assembly at Rs 54,130 and the OLED alone at Rs 35,490, before tax and labour, on a phone launched at Rs 179,999. Google’s repair estimator gives a Pixel Fold inner screen at about £550 to £570 in the UK and about A$1,000 in Australia on a Pixel 11 Pro Fold priced at £1,799 and A$2,799.
Apple’s Duo repair manual, published on launch day, shows why the number is what it is. The bare-panel Inner Display procedure cuts the old panel out of the body, cleans “21 glue pockets”, injects glue by syringe, lets the screen “set for 1 hour” and finishes in a display press; a hinge fault goes instead to the Inner Display Assembly, a whole new body with hinge and screen into which everything else is transplanted. Samsung’s screen-only service refuses any phone with “a bent or broken frame”.
What the law adds, country by country
A manufacturer’s warranty is a voluntary promise. Beside it sits whatever the law of the country says about goods that fail, and that is where a folding screen’s softness meets its sharpest test, because every one of these laws asks whether the goods were as durable as a reasonable buyer would expect, and every one shifts the burden of proof for a period after sale.
- United Kingdom. The Consumer Rights Act 2015 makes durability an aspect of satisfactory quality (s.9(3)(e)). A fault in the first 30 days gives a right to reject for a refund (s.22). For repair, replacement or a later rejection, goods that “do not conform to the contract at any time within the period of six months beginning with the day on which the goods were delivered to the consumer must be taken not to have conformed to it on that day”, unless the trader proves otherwise or the presumption “is incompatible with the nature of the goods or with how they fail to conform” (s.19(14) and (15)). The claim is against the seller, not the maker. Apple’s UK warranty says its own terms “shall not apply to consumer law claims”.
- European Union. Directive 2019/771 requires goods to have the durability “normal for goods of the same type and which the consumer may reasonably expect” (art. 7(1)(d)), makes the seller liable for two years (art. 10), and presumes that “Any lack of conformity which becomes apparent within one year of the time when the goods were delivered” existed at delivery, “unless proved otherwise or unless this presumption is incompatible with the nature of the goods or with the nature of the lack of conformity” (art. 11). Member states may make that two years; France has, for new goods. Germany’s Civil Code applies one year (BGB s.477).
- Australia. The Australian Consumer Law guarantees goods are “durable” as “a reasonable consumer fully acquainted with the state and condition of the goods … would regard as acceptable” (s.54), says goods do not fail that test if “damaged by abnormal use”, and makes any contract term that excludes the guarantee void (s.64). Apple’s Australian warranty says so itself: “Our goods come with guarantees that cannot be excluded under the Australian Consumer Law.” The manufacturer can be sued directly (s.271).
- United States. The Magnuson-Moss Warranty Act stops a maker that gives a written warranty from disclaiming the implied warranty of merchantability, but lets it limit that implied warranty to the written warranty’s length (15 U.S.C. s.2308). There is no federal presumption that a fault within a year was there at sale, and the one class action over a folding screen was sent to arbitration. The regulator’s one relevant intervention is the FTC’s 2018 warning that conditioning a warranty on the use of a particular part or service is unlawful (16 CFR 700.10), which bears on “void the warranty” wording about screen films.
- Elsewhere. New Zealand’s Consumer Guarantees Act carries the same acceptable-quality and durability test as Australia’s. In India, the Kolkata order above is one tribunal applying the Consumer Protection Act to one phone.
None of these laws names a folding phone. What they share is a question the warranties do not ask: not whether the damage came from outside, but whether a screen that marks with a fingernail is as durable as a reasonable buyer of a £1,999 phone would expect. No published court or regulator decision has answered it for a folding phone. The Kolkata commission came closest, and found for the owner.
What it means for you
- The screen is soft, and every maker says so. Treat the handling guide as the specification. A folding phone that lives in a pocket with keys, on a beach, or in a bag with a pen is being used outside the guide, and the warranty says so too.
- A scratch, a mark or a line with no impact is, under the warranty, yours to pay for. Scratches and cosmetic damage are excluded by name. A line or a dead patch at the fold with no visible cause is where the argument happens, and the record from 2019 to the Duo’s launch weekend is that the maker’s first answer is external damage.
- Price the repair before the phone. On the Duo, an inner screen is half the purchase price in every country Apple sells it. On a Fold8 it is $419 to $639 in the United States. A care plan turns that into a fixed fee, at $16.49 or £13.99 a month on the Duo, and still excludes cosmetic damage.
- In the UK, EU and Australia, go to the seller under the law, not the maker under the warranty. In the UK a fault in the first six months is presumed to have been there at delivery unless the seller proves otherwise; in the EU it is a year, in France two; in Australia the guarantee of durability cannot be excluded and reaches the manufacturer. Put it in writing and cite the section.
- In the United States you have the warranty, the care plan and arbitration. The written warranty’s exclusions are the terms, the implied warranty can be limited to the same year, and Samsung’s terms send disputes to arbitration, as the Fold3 case shows.
- If you repair these, the screen-only job is its own trade. Apple’s bare-panel route is a cut-out, a glue-pocket clean, a syringe, an hour’s set and a press; a hinge fault means the whole enclosure. Samsung’s screen-only service refuses a bent frame. Sending a phone back raises its own questions on some models, as the iPhone 18 Pro Max’s battery showed last week, and the assembly route ends in the same calibration step that governs Apple parts generally.
OpinionA judgement on the facts above, not a finding. It rests only on what is quoted on this page.
My view
In my view, folding phones are not ready for everyday use, and the makers’ own documents are the evidence. Their handling guides say the inner screen is damaged by a fingernail, a grain of sand in the hinge or a coin closed inside it. The independent labs measure exactly that: 1.3 out of 5 at Which?, “kratzempfindlich” three years running at Stiftung Warentest, Mohs level 2 against level 7 for the glass on the outside of the same phone. Those are the things a phone meets every day in a pocket. The warranties then exclude scratches, cosmetic damage, wear, external causes, sharp objects and excessive force, which is a list of the ways that screen fails. My read is that the plastic cover is not strong enough for the use a phone gets, and that the warranty terms do not cover the damage the cover lets through.
The makers’ answer is fair as far as it goes. Apple says the Duo’s inner display is built “to withstand the wear of everyday use” and gives it a scratch-resistant coating; Samsung says its thin glass “should be handled with care” and that the film is a consumable it will replace; Which? says the softness “simply has to be to bend”, and I agree that a screen that folds cannot carry thick glass. All three sell a care plan that turns a half-the-phone repair into a fixed fee, and Samsung in Germany replaces the film free four times. But a paid plan is the maker pricing the risk and passing it to the buyer, and the warranty itself, in every country above, covers defects in materials and workmanship and not the damage its own guide predicts. Until the cover can take what a slab phone’s glass takes, or the warranty takes on the failures the handling guide describes, my view is that a folding phone is for someone who will carry it like a camera, in its own pocket, with nothing else, and who has priced the inner screen before buying. That is not most people, and the launch weekend of the most expensive one yet, whatever its cause turns out to be, has not changed my mind.
