Apple is launching a repair program for iPhone 8 users having a problem of some sorts with its logic board. A logic board is a component which houses the CPU, device memory and other components.
This comes in after the company determined that a very small percentage of iPhone 8 devices contain logic boards with a manufacturing defect. The defect may cause devices to restart unexpectedly, display a frozen screen or not turn on at all. The defect does not affect the iPhone X and the iPhone 8 Plus, though.
Also, only the iPhone 8 units manufactured between September 2017 and March 2018 in Australia, China, Hong Kong, India, Japan, Macau, New Zealand, and the U.S are affected. An added benefit is that Apple has made this repair free-of-cost. However, you might have to fix any previous damages to the phone including screen cracks, etc. before submitting your iPhone 8 for the logic board repair.
According to Apple, you can choose from three modes through which you can submit your iPhone 8:
Find an Apple authorized service provider.
Make an appointment at an Apple retail store.
Contact Apple support to arrange a mail-in service via the Apple repair center.
Although, your iPhone will be examined for eligibility before being considered for the repair. And you could also get charged for additional costs in some repairs. But that depends entirely on the condition of the device.
