Despite an IP48 rating for water resistance, the phone offers no protection against particles smaller than 1mm. iFixit deliberately introduced UV-reactive dust into the hinge, and after exposure the phone made severe crunching noises when folded. Disassembly (which requires removing the flexible OLED screen) revealed the hinge mechanism caked in dust, rendering it effectively non-functional, while the two internal halves of the device stayed relatively clean. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why does the Samsung Galaxy Z Fold 8 hinge stop working after dust exposure? The hinge mechanism traps fine dust particles that its IP48 rating cannot block, since IP48 only guards against water and against particles larger than 1mm. An iFixit teardown using UV-reactive dust showed the mechanism caked with debris, causing horrific crunching noises and making the fold motion effectively unusable, even though the display halves themselves stayed relatively dust-free. _Anyone weighing a foldable phone purchase can find durability breakdowns like this on daily.dev._ ### What IP rating does the Samsung Galaxy Z Fold 8 have and what does it protect against? The Galaxy Z Fold 8 carries an IP48 rating, meaning it is water-resistant but only dust-resistant against particles 1mm or larger. Finer dust can still penetrate the hinge mechanism, as shown when UV-reactive dust caused visible caking and mechanical crunching noises during a teardown test. _Readers tracking real-world durability limits of foldables can follow teardown coverage on daily.dev._ ## Similar posts on daily.dev - [Is this the folding iPhone’s creaseless display?](https://daily.dev/posts/is-this-the-folding-iphone-s-creaseless-display--p11b2ksi5) · The Verge · 0 upvotes · 0 comments - [I replaced my laptop with a Samsung Fold 8](https://daily.dev/posts/i-replaced-my-laptop-with-a-samsung-fold-8-j6uxlzz20) · XDA Developers · 0 upvotes · 0 comments - [Teardown of unreleased LG Rollable shows why rollable phones aren’t a thing](https://daily.dev/posts/teardown-of-unreleased-lg-rollable-shows-why-rollable-phones-aren-t-a-thing-uybo9t2mw) · Hacker News · 0 upvotes · 0 comments - [Pixel 10 Pro Fold review: Google’s bet to make foldables sturdy](https://daily.dev/posts/pixel-10-pro-fold-review-google-s-bet-to-make-foldables-sturdy-djzrz34jl) · TechCrunch · 0 upvotes · 0 comments --- Tags: [#tech-news](https://daily.dev/tags/tech-news) [View this post on daily.dev](https://daily.dev/posts/foldable-oled-displays-and-the-bane-of-dust-lxt2ehihl) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Foldable OLED Displays And The Bane Of Dust","url":"https://daily.dev/posts/foldable-oled-displays-and-the-bane-of-dust-lxt2ehihl","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/foldable-oled-displays-and-the-bane-of-dust-lxt2ehihl"},"datePublished":"2026-08-20T18:44:51.664Z","dateModified":"2026-09-14T09:02:25.489Z","description":"A teardown of the Samsung Galaxy Z Fold 8 by iFixit exposes a durability weakness shared with foldable OLED devices generally: dust intrusion into the hinge...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/bbaceb1049e0de6848b3a010a5c08cc5?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/bbaceb1049e0de6848b3a010a5c08cc5?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Hackaday","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Hackaday","logo":"https://media.daily.dev/image/upload/s--JhDfhy70--/f_auto,q_auto/v1767541814/logos/hackaday","url":"https://daily.dev/sources/hackaday"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/foldable-oled-displays-and-the-bane-of-dust-lxt2ehihl","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":5},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"tech-news","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Hackaday","item":"https://daily.dev/sources/hackaday"},{"@type":"ListItem","position":3,"name":"Foldable OLED Displays And The Bane Of Dust"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/foldable-oled-displays-and-the-bane-of-dust-lxt2ehihl#faq","mainEntity":[{"@type":"Question","name":"Why does the Samsung Galaxy Z Fold 8 hinge stop working after dust exposure?","acceptedAnswer":{"@type":"Answer","text":"The hinge mechanism traps fine dust particles that its IP48 rating cannot block, since IP48 only guards against water and against particles larger than 1mm.
