Apple has initiated a replacement program for iPhone 8 devices with defective logic boards. Only a "very small percentage" of incidents have been discovered but, at iPhone scale, that's still something.

From Apple:

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.

Affected units were sold between September 2017 and March 2018 in Australia, China, Hong Kong, India, Japan, Macau, New Zealand, and the U.S.

Apple may restrict or limit repair to the original country or region of purchase.

This Apple program doesn't extend the standard warranty coverage of the iPhone 8.

The program covers affected iPhone 8 devices for 3 years after the first retail sale of the unit.

You can enter your serial number into Apple's system to see if your device is affected.

If it is, contact AppleCare, your local Apple Store, or Apple Authorized Service Provider to schedule an appointment. (And make sure you back up your iPhone 8 before taking or sending it in.)
