Apple examined the phone and classified the damage as a manufacturing defect. The company provided an immediate replacement at no charge, and a technician arranged the swap on the spot from a plain service box.

If the screen had needed repair, the cost could reach $999 for the inner display without AppleCare+, but the AppleCare+ plan reduces the fee to $99. These prices highlight the financial benefit of having AppleCare+ for Duo owners.

The report recommends four simple precautions. First, check that no dust, debris or foreign objects are trapped between the halves before folding; second, apply pressure along the outer edges rather than the centre when opening or closing. Third, avoid forcing the hinge if it feels unusually stiff, sticks or makes odd noises; fourth, never peel off the matte nano‑textured protective coating.

Most importantly, if any obstruction or unusual resistance is felt around the hinge, users should stop using the phone and visit an Apple Store for inspection. Apple staff can determine whether the problem is a defect or user‑induced and advise the appropriate next steps.
