iPhone 8 users complain about the inoperability of their smartphones after installing the update to iOS 11.3. Some Apple gadgets simply stop responding to touch screen.However, all iPhone 8 owners should not panic. It seems that only gadgets, the screens of which have been replaced by someone other than an Apple Service Center, are no longer functioning properly. It is hard to say yet how widespread this problem is. We can only hope that Apple will soon release an update that fixes the functionality of smartphones. Recall that last year there was a similar situation with the iPhone 7. Then, it took the company a week to release the necessary patch.
