Apple has today announced a new Logic Board Replacement program for some iPhone 8 users.
They will be issuing free repairs for iPhone 8 devices that are affected by freezing, unresponsive screens and reboots. According to Apple, "a very small percentage" of iPhone 8s have logic boards with a defect in.
You can check if your phone is eligible for a repair by going to this website. You will need to enter your iPhone's serial number. Affected phones were sold between September 2017 and March 2018, in Hong Kong, China, India, Japan, Macau, U.S and New Zealand.
The problem only affects iPhone 8 models, not the Plus version or any other iPhones. Customers can make appointments at a local Apple Store, or arrange a mail-in service via Apple Support.
It is recommended by Apple that you back your device up through iCloud or iTunes before you send your device in for repair. Any screen damage will need to also be fixed before the logic board repair.
