Video shows iPhone Duo screen wrinkling above hinge when pressed
A Weibo hands-on clip shared by Ice Universe shows several iPhone Duo units dimpling over the hinge; Apple has not confirmed the glass type used.
A hands-on video shared on October 20, 2026 shows that the section of the iPhone Duo's inner display above the hinge depresses when pressed with a finger, according to footage posted by Weibo user Kang and circulated by the tipster account Ice Universe, as reported by GSM Arena.
Kang says pressing the screen in that area can produce wrinkles that disappear once the finger is moved. According to Kang, multiple iPhone Duo units were tested and displayed the same behavior.
Ice Universe speculates that the effect may be related to variable-thickness ultra-thin glass, which uses a thinner strip over the hinge. Apple has not confirmed whether it uses Corning's variable-thickness glass in the iPhone Duo.
Earlier glass work
A couple of years before October 2026, glass maker Corning unveiled variable-thickness glass, which it calls Corning VtG, with a thinner strip over the hinge and thicker glass elsewhere.
