Apple’s latest iOS 11.3 software update is causing iPhone 8 devices with third-party repaired screens to stop working.

Users who have had a screen repair performed by a third party, rather than with Apple, on their iPhone 8 smartphones found that the iOS 11.3 update stopped the touchscreen from working, reports Motherboard. The update was pushed out on 29 March, introducing Apple’s promised iPhone battery health information, as well as the ability to turn off the slowing down of smartphones related to the battery following the scandal in December.

The screens continue to display the homescreen once updated to iOS 11.3 but cannot be interacted with, effectively rendering the affected iPhone 8 device unusable without warning from Apple.
