Two iPhone Duos, water and dust: the hinge question viewers won't let go

A foldable phone draws attention twice: when it unfolds, and when an expensive pair is subjected to water and powder. On the morning of November 3, a Ruliweb summary of a linked two-device test drew attention. We could not play the entire linked YouTube video independently.

A Ruliweb post published at 9:58 a.m. described two devices being exposed to water and dust and subsequently opened. Its author distinguished the main electronics from the display edge and hinge, claiming the latter retained moisture and debris. This remains an account by the post's author, not independently verified lab findings.

Two points caught commenters' attention: the cost of using two premium phones and what a water-resistance claim actually covers. Some asked whether a working circuit board settles the separate question of the hinge's long-term function. The observed page snapshot showed 5,482 views and 51 recommendations.

Visible comments expressed shock at sacrificing two costly devices, questioned whether protected main electronics alone mean the folding mechanism is safe, and debated the test method. The post's author corrected an earlier misreading of the cost. These are observations from one thread, not a representative consumer survey.

An IP rating describes resistance under defined test conditions; it is not a promise of immunity in every situation forever. Apple notes that resistance may diminish through ordinary wear. A one-off demonstration and long-term durability research answer different questions.

Verified: the dated forum post, visible engagement metrics and comments, plus its YouTube link. Apple's Korean specifications describe an IP68 rating; they do not establish that the linked demonstration followed a certification procedure. Exact test conditions, hinge lifespan and failure rates require further verification.

Next checks: the complete video, uploader and publication date; detailed experimental conditions versus certification requirements; and manufacturer hinge-care guidance. The sampled thread alone cannot establish noncompliance or real-world failure rates.
