Common questions

Is the crease a defect?

No. Every book-style foldable has one. A crack, line or lifting cover layer is different: on October 26 Apple acknowledged an inner-display issue on a small number of units and is offering replacements through AppleCare.

What does an inner-display repair cost?

$999 without AppleCare+, $99 with it, per Apple's published fees.
