has launched a repair program to fix defective logic boards in the iPhone 8. The company says a small number of faulty units were sold between September 2017 and March 2018 in Australia, China, Hong Kong, India, Japan, Macau, New Zealand, and the U.S. People who own an iPhone 8 can enter their serial number to see if it qualifies for a fix. The issue, accord to Apple, led to screen freezes, random restarts, and defective startups. The iPhone 8 Plus and iPhone X are not affected. People with an eligible iPhone 8 can drop it off at an Apple Store, mail it in, or bring it to an authorized repair shop. Apple suggests people backup their phone before bringing it in. The program will be available for up to three years from the iPhone 8's September 2017 launch.
