Apple Says Small Number of iPhone Duo Screens Are Failing

What changed

Some iPhone Duo units are developing severe internal-display damage within minutes or about a day of use, just one week after Apple launched its first foldable phone at a reported $2,000. Apple says only a “small number” of devices are affected, while iFixit’s teardown points to a possible mechanical problem near the hinge.

Why it matters

The damage is strikingly consistent: bright lines start below the middle of the OLED and run toward the bottom and right edges. Some phones also develop dead pixels along the crease. Once the display layers are damaged, the practical fix is replacement, and that screen reportedly costs about half the phone’s price.

The pattern also suggests this may be more than ordinary wear. Owners have described unusual resistance or clicking while closing the phone, followed by the lines appearing on-screen. iFixit’s CT scans place the apparent failure point below the ribbon cable, where the hinge-support mechanism changes width.

The leading theory is that a narrow support component may not move far enough to make room for the display’s bend. That could press continuously on the OLED until its pixel matrix fails. It remains a theory, and neither the failure rate nor the root cause is confirmed.

Apple has replaced some defective phones, but replacement availability and any broader corrective action remain unclear. For a $2,000 device whose defining feature is the screen folding safely thousands of times, that uncertainty is the real problem: buyers may not yet know whether they encountered a rare bad unit or a weakness built into the hinge itself.
