4 iOS Could Reject It
After being updated to the latest iOS 11.3 software version, thousands of iPhone 8 devices have shown signs of defunct screen/touch functionality, according to repair technicians across the country.
According to 9to5Mac, “It looks like Apple is using a custom microchip that pairs with the display. Once a third-party repairs a screen, they must also upgrade the microchip, otherwise iOS will reject all touch input from the device.”
It’s possible that Apple could rectify this problem with a software update, but at the time of writing, no remedy has been issued.
