iPhone 8 Logic Board Replacement Program

Apple has determined that a very small percentage of iPhone 8 devices contain logic boards with a manufacturing defect. Affected devices may experience unexpected restarts, a frozen screen, or won't turn on. Apple will repair eligible devices, free of charge.

If your iPhone 8 has an eligible serial number, Apple will repair it, free of charge. Use the serial number checker to see if your device qualifies for this program.

This program does not affect iPhone 8 Plus models or other iPhone models.
