It has been reported that iOS 11.3 has disabled some iPhone 8 touch displays. The devices affected are those who have had third party displays installed. These displays are typically installed by local repair shops and are not affiliated with Apple.
I’ve been a supporter of the Right to Repair movement and Apple once again disappoints. Perhaps the issue is a anomaly but if the past is pattern and without providing comment, then it feels like spite.
Louis Rossman has a good breakdown video you can watch for more info.
UPDATE: Another relivent story today: FTC: Warranty-voiding language like Nintendo’s and Sony’s is illegal
