iPhone 14 Pro and Pro Max owners faced this problem. On the network you can find many shots that show what these stripes look like.
The defect occurs when turning on or unlocking this or that gadget. There were rumors that such a problem could have arisen due to a violation during the manufacture of the devices. For example, due to a lack of internal equipment. Apple has assured us that this is not the case.
According to MacRumors, the “apple” company is already preparing a solution: the new iOS update will contain all the necessary fixes. After it is released, the problem should disappear.
As a reminder, iOS 16.3 is currently undergoing beta testing. The exact release date of the new version of the OS is unknown, but the update is expected to be available for download in a few weeks – in February or March.
