Analysis and impact
从拆解结果看，Z Fold 8 的内部布局延续了三星折叠屏机型一贯的高集成度，电池、主板等核心部件更换难度较大。iFixit 提到，铰链组件与屏幕面板之间的连接方式使得维修时需要处理多层粘合与精密排线，非专业用户自行拆修的风险较高。这也是其评分低于多数直板旗舰的主要原因。来源
iFixit 拆解三星 Galaxy Z Fold 8 的铰链区域
值得注意的是，IP48 中的“4”代表防护大于 1 毫米的固体异物，而“8”则对应持续浸水防护。这意味着该机在防尘方面并非完全密封，铰链活动部件仍留有进尘缝隙。iFixit 的拆解显示，三星在铰链内部加入了一定程度的防护结构，但并未从根本上解决折叠屏机型在防尘与可维修性之间的长期矛盾。原文未提供三星官方对此次评分的回应。来源

iFixit has provisionally given Samsung's Galaxy Z Fold 8 a repairability score of 4 out of 10, which largely hinged on… well, the hinge. In its teardown of the device, iFixit found that because it carries an IP48 ingress rating - meaning it isn't protected against particles under 1 millimeter - dust and sand could make its way into the hinge mechanism, a component that's difficult to repair or replace.
"After working the Fold 8 open and closed, the hinge started making truly awful crunching and grinding noises, and the phone stopped opening normally," iFixit said. "Samsung has previously treated the hinge and inner display as one replacemen …
