Apple just announced the IPhone 8 Logic Board Replacement Program, after determining that ?a very small percentage? of iPhones 8 may come with defective logic boards.
According to Apple, the affected devices may restart unexpectedly or display frozen screens, as well as not even turning on. All will be repaired free of charge by the company.
Affected units were sold between September 2017 and March 2018 in Australia, China, the United States, Hong Kong, India, Japan, Macau and New Zealand. That is, if you bought your iPhone 8 in Brazil, there is nothing to worry about; if you have an iPhone 8 Plus, regardless of where it was purchased, ditto.
Users who are in doubt whether their iPhone 8 does or is not part of the program (if they purchased it in the USA, for example) should enter the device's serial number on this page for verification.
Apple said it could restrict the repair to the original country of purchase of the device and says it does not extend the original warranty on the iPhone 8. Devices will be covered for up to three years from the original date of purchase.
