Apple acknowledges iPhone Duo display ‘issue’ after reports of cracked screens

What happened

Many iPhone Duo owners reported cracked and broken inside screens. Often a bright line runs from the center of the screen to the right side. Apple told Bloomberg and 9to5Mac that it is aware of "an issue impacting the inner display" on a "small number of iPhone Duo units." If your phone is affected, Apple says to contact AppleCare for a replacement.

How the problem seems to start

Soon after launch, users said the hinge (the part that lets the phone fold) would tighten. When they opened the phone, the screen cracked and the bright lines appeared. One user in Australia said an Apple Store replaced their phone "on the spot." iFixit, a company that takes devices apart to study them, published a teardown of the phone. It suggests the foldable screen may be pushing against a center bar where the damage happens.

Key facts

• The bright line usually runs from the center of the screen to the right side.
• Apple's advice: contact AppleCare for a replacement.
• The Verge asked Apple about the reports but had not received an on-the-record reply.

Why it matters

The iPhone Duo is one of the first devices to launch under new CEO John Ternus, who took over from Tim Cook. A screen problem on a new foldable phone can make buyers worry about the design. Apple's quick admission and replacement offer may help calm customers.

What to watch

• Whether Apple shares more details about the cause of the cracks.
• Whether the number of affected phones grows.
• Any design or repair changes Apple announces for the hinge or inside screen.
