When new message comes, the iPhone 14 Pro / 14 Pro Max should have a notification and screen will light up by itself, but some people faced this strange problem when they replaced a new screen or when their screen was refurbished.

This problem was caused by the missing black sticker between the display proximity sensor area of plastic frame, when the manufacturers glue a new screen with new frame, they did not put the black sticker over there, to solve this problem, you just need put a black sticker over the red area as this picture.

Above picture is showing you what do to, please make sure you can do it otherwise give your phone to repair shops for help. Please share this tip to anyone who has this problem.
