Some iPhone 14 Pro screens have a horizontal line problem
The horizontal line problem has only appeared on iPhone 14 Pro and iPhone 14 Pro Max models for now. It is unclear whether the horizontal yellow and green lines appearing on the screen from time to time are hardware problems. Because, according to user information, this problem appears in new areas of the phone. On the other hand, those who have the problem report that it becomes more frequent with iOS 16.2, but they state that this problem is also present in previous versions of iOS 16.
There is no definite solution to the problem
If you have an iPhone 14 Pro and you are facing the problem of horizontal lines appearing on the screen, you can try to turn off the Always On Display feature or manually set the screen timeout. As a result of these actions, some users report that the horizontal line problem is reduced.
However, some Reddit users suspect that the problem may be caused by LG. As it is known, LG is among the screen suppliers of the iPhone 14 Pro models, and according to those who have experienced the problem, the problem mainly occurs in models using LG panels. Additionally, Apple is currently developing iOS 16.3 with developers and public beta testers, but the update is not expected to be released until early next year.
